NWS HOUSTON/GALVESTON TX
IRIS SYSTEM

[srainhoutx]

Update from Jeff:

A truly devastating day across SE TX and Harris County with incredible rainfall amounts and historic flooding.

Will deem this the most significant flood event in Harris County since Tropical Storm Allison.

Harris and 8 other counties in SE TX are requesting a federal disaster declaration.

A total of 240 billion gallons of water fell over Harris County resulting in major flooding in over 13 of our 22 watersheds. Over 110 subdivisions have reported house flooding…and initial estimates of house flooding are potentially very high.

Rainfall amounts have averaged 14-17 inches over Waller County into NW Harris County with a large area of 5-10 inches NE of US 59 in Fort Bend and Harris Counties. Almost all of this rain fell in a 12-24 hour period with incredible short term rainfall rates overnight. At times rainfall rates were over 4 inches in 1 hour and several of the gages have recorded over 100-yr and 500-yr flood levels.

Watersheds with significant channel/house flooding:

Brays Bayou (about 1 ft below Memorial Day 2015 levels)

Keegans Bayou

South Mayde Creek

White Oak Bayou (highest levels since 2002)

Halls Bayou

Greens Bayou (highest level since TS Allison)

Cypress Creek

Little Cypress Creek (appears to be record flooding)

Willow Creek

Spring Creek

Horsepen Creek (record flooding)

Langham Creel (record flooding)

Bear Creek

West Fork San Jacinto River

East Fork San Jacinto River

Lower San Jacinto River below Lake Houston (crest on Thursday)

Water levels in upper Cypress Creek have risen to levels that is resulting in overflow across the basin divide into upper Bear Creek and South Mayde Creek and this will continue for the next few days.

Addicks and Barker Reservoirs:

Record pool elevations are forecasted on both Addicks and Barker. HWY 6 in Addicks is already under water and will remain under water for many days. It appears that water levels will rise into the streets of the subdivisions that surround the Govt owned land.

The previous record of Addicks was March 1992 of 97.46 ft and the forecast is currently taking Addicks to 102.3ft.

The previous record in Barker was 93.60 ft in March 1992 and is forecast to go to 95.5 ft.

Forecast:

Air mass has been worked over, but large upper low responsible for all the rainfall remains in a favorable location to our NW to at least maintain a threat of additional rainfall. Air mass south of old outflow boundary remains moist and unstable and capable of additional activity over the next 24-48 hours. Not expecting the magnitude of rainfall we saw overnight, but an additional 1-3 inches will be possible over the next 48 hours. Any additional rainfall at this point with the watersheds so full will slow recessions or result in additional rises.

Not overly confident in any time period for additional development, but will need to keep an eye to the WSW for any disturbance that may move out of MX and into the region

[ticka1]

just have to keep an eye on radar tonight and in the morning. It wont take much to flood again.

[jasons2k]

Radar looks concerning to me. It looks like E-W bands trying to setup to the west, with storms training in them.

[davidiowx]

Radar looks concerning to me. It looks like E-W bands trying to setup to the west, with storms training in them.

Was coming on here to post this. I am wondering if the clearing and "sun" coming through may have contributed to the development. I am just going to check the radar every 30 min or so and see what it looks like as the night goes on. I

[davidiowx]

double post

[Andrew]

Analyzing radar, satellite, and current conditions indicate that upper level support is not nearly as impressive as this morning. Mid to upper level moisture advection is not nearly as deep as earlier. Paired with that, the atmosphere still seems pretty worked over. Pwats are also down by about half an inch compared to earlier in the day. Could still see some more rain tonight but i suspect that breaks in the precipitation paired with much lower rain rates will limit totals. With that said any rain will aggravate the flooding situation and drain off. Another interesting note is the ECMWF suggests we could see yet another round Tuesday evening/ Wednesday. So another thing to keep an eye on.

[Ounce]

I will be curious to see in the morning how far north those storms south of Brownsville have moved.

[Andrew]

I will be curious to see in the morning how far north those storms south of Brownsville have moved.

Overall movement and flow is to the east and ENE south of the boundary.

[Ptarmigan]

While additional showers and storms are expected this evening into the overnight hours and early Tuesday, rainfall totals do not appear to be as high as we experienced overnight and today. That said the ground is fully saturated and the bayou's are not receding as fast because of the magnitude of the Flood Event across Waller and NW, N Harris and Montgomery Counties. Another concern is River Flooding waves moving down from Central and N Texas. As long as that pesky upper low/trough sits and spins nearly stationary, we will need to monitor for any thunderstorm complex that organizes to our SW and W.

That water vapor image satellite shows a typical setup for flooding.

I have seen flood events in which there is a upper level low over Colorado or Four Corners. May 1989, December 1991, and March 1992.

THE FLASH FLOOD WATCH IS NOW IN EFFECT FOR

* A PORTION OF SOUTHEAST TEXAS...INCLUDING THE FOLLOWING
AUSTIN...BRAZORIA...BRAZOS...BURLESON...CHAMBERS...COLORADO...
FORT ...BEND...GALVESTON...GRIMES...HARRIS...HOUSTON...
JACKSON...LIBERTY...MADISON...MATAGORDA...MONTGOMERY...POLK...

* THROUGH WEDNESDAY MORNING

* ADDITIONAL THUNDERSTORM ACTIVITY WILL BE POSSIBLE TODAY AND
WEDNESDAY. THE FLASH FLOOD WATCH MAY BE EXTENDED YET AGAIN FOR
WEDNESDAY. SCATTERD SHOWERS AND THUNDERSTORMS MAY FORM TODAY BUT
COULD BE CAPABLE OF PRODUCING RAINFALL RATES OF 1 TO 2 INCHES OF
RAIN AN HOUR. STORMS MAY BE SLOW MOVING SO LOCALIZED HIGHER
RAINFALL AMOUNTS WILL BE POSSIBLE. GIVEN THE ONGOING FLOODING
CONDITIONS AND THE EXPECTATION OF THUNDERSTORM ACTIVITY THE
FLASH FLOOD WATCH WILL CONTINUE.

* AVOID TRAVEL IN AND AROUND FLOODED AREAS. MOST PEOPLE WHO DIE
IN FLASH FLOODING WILL DIE IN THEIR VEHICLES. IF IN A FLOODED
AREA STAY WHERE YOU ARE...AT HOME OR AT WORK. NEVER DRIVE INTO A
FLOODED ROADWAY. TURN AROUND DONT DROWN!

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FLASH FLOOD WATCH MEANS THAT CONDITIONS MAY DEVELOP THAT LEAD
TO FLASH FLOODING. FLASH FLOODING IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION
SHOULD FLASH FLOOD WARNINGS BE ISSUED.

[Katdaddy]

The large upper level low remains over the Rockies. The Flash Flood Watch has been extended through Wednesday morning due to saturated grounds, ongoing flooding, and additional disturbances which could lead to thunderstorm development later today. Mesoscale models show development near the coast later this morning along the coast and then moving inland. The Flash Flood Watch may need to be extended through Wednesday should a squall line/mesoscale convective system develop across Central TX late tonight and move across SE TX Wednesday morning. A cold front and strong disturbance on Thursday may require an extension of the Flash Flood Watch. The SPC has a marginal risk area for Central TX, most of S Central & SE TX, and NE TX on Wednesday. The marginal risk area then shifts S Thursday to include all of SE TX, S Central TX, and a large portion of Central TX.

...SOUTHERN PLAINS...

MODELS ALONG WITH THE UPDATED WPC FORECAST NOW DOWNPLAY THE
LEADING EDGE PRECIPITATION MOVING INTO THE MISSISSIPPI
VALLEY...WHICH WILL ENCOUNTER THE DRYING AND BLOCKING INFLUENCE OF
RIDGING...BUT NOW WILL PLAY UP THE CONVECTIVE CLUSTERS THAT WILL
FORM IN A FAVORABLE CAPE AND SHEAR ENVIRONMENT OVER WESTERN
KS/OK/TX TODAY. EARLY MORNING ACTIVITY WAS VERY WIDELY SCATTERED
AT 06Z...BUT MODEL OMEGA FIELDS AND SOME OF THE MORE TRUSTED
QPFS...HRRR...NSSL WRF...GEM REGIONAL...STRONGLY INDICATE THE
GROWTH OF ADDITIONAL STORM CLUSTERS ALONG THE UPPER TEXAS COAST
AND SOUTHWEST LOUISIANA EARLY TUESDAY. THIS APPEARS DRIVEN BY WARM
ADVECTION NORTH OF THE
RESIDUAL OUTFLOW BOUNDARIES AND A VERY SUBTLE SHORTWAVE ALOFT THAT
WAS ENHANCING ACTIVITY OVER SOUTHWEST OKLAHOMA AND WESTERN NORTH
TEXAS. CONFIDENCE ALONG THE UPPER TEXAS COAST IS NOT HIGH...GIVEN
THE SUBTLE FORCING AND RECENT LARGE SCALE OVERTURNING...BUT THERE
IS GOOD MODEL AGREEMENT...WITH THE BULK OF NEW RAINFALL FORECAST
TO BE CENTERED ON THE EASTERN SIDE OF HOUSTON. MODELS SUGGEST THAT
IF NEW CONVECTION BECOMES ESTABLISHED IT MAY PERSIST WELL INTO THE
DAY GIVEN FAVORABLE INFLOW...ALTHOUGH THE LACK OF WELL DEFINED
DEEP LAYER LIFT SUGGESTS THE CONVECTION MAY NOT BE OVERLY
ORGANIZED ON A LARGE SCALE. FOR THIS REASON...A SLIGHT RISK IS
MAINTAINED OVER THE HARD HIT AREAS OF THE UPPER TEXAS COAST.

FARTHER NORTH AND WEST...SCATTERED CONVECTION WAS ALREADY SPILLING
OUT INTO THE HIGH PLAINS OF NM/TX/OK PANHANDLES. HEIGHT FALLS
BECOME SOMEWHAT PRONOUNCED LATER TODAY PUSHING OUT INTO KS AND
NORTHWEST OK...AS A SHORTWAVE EMERGES FROM THE LINGERING UPPER LOW
OVER THE ROCKIES. THIS DRIVES A REINFORCING BOUNDARY DOWN INTO THE
SOUTH ROLLING PLAINS NEAR/EAST OF LUBBOCK. AHEAD OF THIS
BOUNDARY...THE LEADING PACIFIC COLD FRONT REMAINS IN PLACE OVER
CENTRAL OK/TX...BUT WINDS DO BACK...WITH MOISTURE DEPTH INCREASING
WESTWARD...AND PLENTY OF HEATING RESULTING IN WIDESPREAD MODERATE
CAPE VALUES IN THE NAM/SREF/GFS FROM SW KS TO SW TX...GREATEST
VALUES BEING DOWN ACROSS SOUTHWEST TEXAS. ALTHOUGH IT IS HARD TO
HAVE TOO MUCH CONFIDENCE IN THE DETAILS...THE FORCING MECHANISMS
DO SEEM TO SUPPORT THE NEAR UNANIMOUS SIGNAL IN THE HI-RES MODELS
FOR THREE DISTINCT SWATHS OF PRECIPITATION...ONE NEAR THE HEIGHT
FALLS UP NORTH...ONE WHERE THE BETTER FRONTAL PUSH INTERSECTS
GREATER MOISTURE / WESTERN RED RIVER VALLEY...AND ONE DRIVEN BY
THE STRONGER INSTABILITY AND SUFFICIENTLY WIDESPREAD CONVECTIVE
INITIATION OVER SOUTHWEST TEXAS / EDWARDS PLATEAU. THROUGHOUT THIS
REGION CAPE/SHEAR PROFILES SUPPORT ORGANIZED CONVECTION CAPABLE OF
GROWING UPSCALE AND BEING SUSTAINED AS EVENTS TREK EASTWARD INTO
THE OVERNIGHT HOURS. WITH LOW LEVEL INFLOW BEING ON THE LIGHT
SIDE...CONVECTION MAY SLIDE EAST RELATIVELY QUICKLY...BUT WILL
ALSO CROSS MANY AREAS THAT HAVE WET ANTECEDENT CONDITIONS...AND
ADDITIONAL CONVECTIVE RAIN RATES COULD LEAD TO FLASH FLOODING.

OF NOTE...THE HEAVIEST OF THE THREE SWATHS IN THE HI-RES MODELS IS
THE ONE COMING OUT OF SOUTHWEST TEXAS...OWING TO GREATER
MOISTURE/INSTABILITY AT THAT LATITUDE. IT IS WORTH NOTING THAT THE
00Z WRF-ARW DROVE THIS EVENT VERY FAR SOUTH...AFFECTING SAN
ANTONIO AND SOUTHWARD. WE SIDED WITH THE CONSENSUS THAT WAS
FARTHER NORTH...ALONG AN AXIS THROUGH AUSTIN...AS THE WESTERLY
UPPER FLOW AND SOUTHERLY LOW LEVEL INFLOW DID NOT APPEAR
ESPECIALLY CONDUCIVE TO A STRONG RIGHT HAND TURN. WILL HAVE TO
MONITOR TRENDS AND CONTINUE TO ADJUST WITH THE NEXT CYCLE.

Yep. I can attest to that. HCC is closed today. Still be weather wary folks. Just because it has no rained in awhile (hours...LOL), does not mean that this could be not be problem down the road with any amount of rain falling. Stay tuned here ( our mets...Srain, Andrew, Jeff, Brooks, David and Wxman 57) will guide you through. Also the folks that provide information to pass on here are so welcomed during times of weather events. A BIG thank you goes out to you all.

COAST. GENERALLY EXPECT TO SEE MVFR CEILINGS TODAY WITH SHRA POSSIBLE
THIS MORNING AND TSRA POSSIBLE THIS AFTERNOON. BEST COVERAGE MIGHT END
UP BEING BETWEEN IAH AND GLS. ANTICIPATE A BREAK TONIGHT WHICH COULD
ALLOW FOR A POSSIBLE LOWERING OF AREA CEILINGS AND VISIBILITIES INTO

.PREV DISCUSSION... /ISSUED 501 AM CDT TUE APR 19 2016/

..FLASH FLOOD WATCH TO CONTINUE TODAY...

DISCUSSION...
AFTER A LONG MORNING ON THE WARNING DESK YESTERDAY...BACK AT THE
FORECAST DESK ONE MORE TIME. AREA RADAR ARE RATHER QUIET COMPARED
TO 24 HOURS AGO. SURFACE OBSERVATIONS SHOWING SOME PATCHY FOG WITH
OVERALL STABLE BOUNDARY LAYER MAINLY FROM BRENHAM TO COLLEGE
STATION OVER TO HUNTSVILLE. SURFACE ANALYSIS ALSO SHOWS 70
DEWPOINTS JUST OFF THE COAST WHICH MAY STILL ADVECT INLAND DESPITE
A WEAK PRESSURE GRADIENT. VAD WIND PROFILES AT THE KHGX 88D SHOW
30-35KTS JUST 2000-5000FT AGL VEERING FROM S TO SW WHICH SUGGESTS
WARM ADVECTION PATTERN. ALOFT LOOKING AT WATER VAPOR
IMAGERY...CLOSED UPPER LEVEL LOW WAS LOCATED OVER THE CENTRAL AND
NORTH ROCKIES. UPPER LEVEL RIDGE HAS WEAKENED OVER THE MISSISSIPPI
AND OHIO RIVER VALLEYS WHILE A RIDGE HAS STRENGTHENED OVER THE
PACIFIC COAST. IT APPEARS THAT THIS BLOCKING PATTERN MAY BE IN THE
PROCESS OF BREAKING DOWN THE NEXT COUPLE OF DAYS. SYNOPTIC MODELS
SEEM ON TRACK WITH THIS SCENARIO.

TODAY LOOKS LIKE MORE OF A RECOVERY DAY FOR THE ATMOSPHERE. BUT AS
NOTED WITH THE VAD WIND PROFILE...COULD SEE AN INFLUX OF MOISTURE
ALONG THE COAST LATER THIS MORNING AND FURTHER INLAND LATER THIS
AFTERNOON. WATER VAPOR IMAGERY SHOWS WHAT LOOKS LIKE A COUPLE OF
WEEK SHORT WAVE TROUGHS THAT COULD BE ON TRACK TO MOVE OVER THE
AREA TODAY SUPPORT AT LEAST SOME BROAD LARGE SCALE ASCENT. IT IS
HARD TO TELL IF THE MODELS ARE RESOLVING ANY OF THESE FEATURES OR
NOT. MESOSCALE MODELS LIKE THE HRRR AND THE TEXAS TECH WRF SHOW
THUNDERSTORM DEVELOPMENT LATER IN THE MORNING ALONG THE COAST AND
THEN INLAND. LOOKS LIKE CONVECTIVE INITIATION MAY BE ALONG A
BOUNDARY MOVING NORTH OUT OF THE GULF. WRF-ARW HAS A HINT OF THIS
AS WELL BUT NOT AS PRONOUNCED. RIGHT NOW THINK A GENERAL 40-60
PERCENT RAIN CHANCE WILL COVER THE POSSIBILITY OF SCATTERED
ACTIVITY. JUST WORRIED THAT IF SOME OF THESE STORMS GET A BIT MORE
ORGANIZED THEN WE WILL SEE RAIN RATES BACK IN THE 1-2 INCH AN HOUR
RANGE. PRECIP WATER VALUES ARE STILL EXPECTED TO BE AROUND 1.6-1.7
INCHES. BASED ON UPWIND CORFIDI VECTORS...STORM MOTIONS WILL BE
ON THE SLOW SIDE SO A LOCALIZED SPOT OF 2-3 INCHES OF RAIN WILL BE
POSSIBLE. IT IS FOR THIS REASON WE WILL CONTINUE THE FLASH FLOOD
WATCH UNTIL 12Z WEDNESDAY.

THE FLASH FLOOD WATCH MAY NEED TO BE EXTENDED THROUGH WEDNESDAY.
LOOKS LIKE GFS/NAM AND THEN HIGH RES WRF MODELS WANT TO BRING A
SQUALL LINE/MCS INTO SE TX LATE TONIGHT INTO WEDNESDAY MORNING.
GFS SHOWS PRECIP WATER VALUES GOING UP TO 1.8 INCHES WITH S/SW
BOUNDARY LAYER FLOW AROUND 20-30KTS. THIS WOULD CERTAINLY SUPPORT
MORE HEAVY RAINFALL. A STRONG SHORT WAVE TROUGH ALSO ROUNDS THE
BASE OF THE MAIN UPPER LOW NOW OVER THE PLAINS THROUGH THURSDAY. A
COLD FRONT WORKS INTO THE AREA DURING THIS TIME AND MAY BE THE
FOCUS FOR MORE RAINFALL. HATE TO SOUND LIKE A BROKEN RECORD BUT AT
LEAST ANOTHER CHANCE FOR THE FLASH FLOOD WATCH TO BE EXTENDED.
RAINFALL AMOUNTS FOR THE NEXT 3 DAYS ARE IN THE NEIGHBORHOOD OF 2
TO 4 INCHES WITH OBVIOUSLY LOCALLY HIGHER AMOUNTS.

COLD FRONT WORKS THROUGH THE AREA THURSDAY NIGHT SO EXPECT SOME
DRIER CONDITIONS OVER THE WEEKEND. WARM AIR ADVECTION PATTERN SETS
UP AGAIN SUNDAY INTO EARLY NEXT WEEK WHICH WILL SUPPORT SOME LOW
20-30 PERCENT RAIN CHANCES.

LIGHT TO MODERATE ONSHORE WINDS ALONG WITH PERIODS OF SHOWERS AND
THUNDERSTORMS WILL PERSIST UNTIL THURSDAY NIGHT WHEN A COLD FRONT
MOVES THROUGH THE AREA. THE LIGHT TO MODERATE OFFSHORE WINDS BEHIND

Storms firing up again all around Beaumont. Seems to be more eastward towards our area so far. 4-5" yesterday for us. Nowhere near what you guys received in HOU. Any additional rain today will be quick to flood. Here and HOU. Stay safe my friends. Eyes to the skies!

The only areas that may see heavier showers and storms today via the 14Z HRRR seems to be focused along and East of Galveston Bay with isolated scattered showers inland. The feature offshore is at the upper levels and could enhance the Coastal/Bay activity and on toward Beaumont and Lake Charles. Will watch the trends today for any unforeseen upper disturbances back to our West rotating beneath that pesky upper low that appears to be finely shearing out and slowly moving NE this morning.

MESOSCALE PRECIPITATION DISCUSSION 0131
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1123 AM EDT TUE APR 19 2016

AREAS AFFECTED...SOUTHEAST TX

CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE

VALID 191521Z - 192121Z

SUMMARY...SCATTERED THUNDERSTORMS ARE EXPECTED TO FORM IN AN AREA
THAT RECEIVED HEAVY RAINFALL YESTERDAY ACROSS SOUTHEAST TX. FLASH
FLOODING IS POSSIBLE WITHIN THIS SATURATED AREA.

DISCUSSION...A MESOANALYSIS FOR THE REGION DEPICTS A COUPLE WEAK
WAVES OF LOW PRESSURE ALONG A BAROCLINIC ZONE JUST OFF THE MIDDLE
AND LOWER TX COAST. THE SURFACE FEATURES LIE EAST OF AN AREA OF
DARKENING ON WATER VAPOR IMAGERY MOVING ACROSS SOUTH-CENTRAL TX.
OVER THE TOP OF THE NORTHERN WAVE, A MOISTURE GRADIENT HAS SET UP
IN THE FORM OF A COASTAL FRONT, SEPARATING GULF MOISTURE FROM
DRIER CONTINENTAL AIR. PRECIPITABLE WATER VALUES OF 1.77" WERE
DERIVED VIA GPS AT GALVESTON TX WITH VALUES JUST ABOVE 1.6" IN
SOUTHWEST LA. MLCAPES IN THE AREA ARE 500+ J/KG WHILE MUCAPES ARE
1000+ J/KG. THE INFLOW AT 850 HPA IS 25 KTS FROM THE SOUTHWEST.

THE CAM GUIDANCE IS NEARLY UNANIMOUS IN IMPLYING THAT THE ZONE OF
MOISTURE GRADIENT WOULD BE THE FOCUS FOR CONVECTION ROUGHLY
BETWEEN 16-21Z. RAP GUIDANCE HAS THE LOW-LEVEL INFLOW DECREASING
WITH TIME, IMPLYING THAT CELLS SHOULD BE OF A PULSE NATURE. CELL
MOTION SHOULD BE NORTHEAST AT 10-15 KTS, MOVING ALONG WITH THE
850-400 HPA MEAN WIND. SHOULD ORGANIZED ACTIVITY OCCUR, IT WOULD
PROPAGATE SLOWLY TO THE EAST-SOUTHEAST. ANY CONVECTION IN THIS
REGION COULD STRENGTHEN THE TEMPERATURE DIFFERENTIAL ALONG THE
MOISTURE GRADIENT, MAKING IT A POTENTIALLY MORE IMPORTANT
CONVECTIVE BOUNDARY. AVAILABLE MOISTURE IMPLIES HOURLY RAIN RATES
UP TO 2", WHILE CAM GUIDANCE INDICATES 3-5" IS POSSIBLE LOCALLY.
WITHIN A SATURATED/FLOODED AREA, HEAVY RAINS COULD LEAD TO OR
RENEW FLASH FLOODING.
