May 2016: Shower/Storm Chances To End May

[ticka1]

Will our wet pattern continue into May? Or will April showers bring May flowers?

[srainhoutx]

The afternoon Updated quantitative precipitation forecast continues to suggest a potential Heavy Rainfall Event may be ahead, particularly next weekend into the early days of May. We encourage everyone to monitor the weather carefully this week as we receive more data and fine tune the sensible weather forecast.

[djjordan]

Even if it is upstream, that doesn't bode well for us here in SE Texas, so yes stay tuned to forecasts this week.

[srainhoutx]

The 04/25/2016 12Z GFS suggests total quantitative precipitation totals generally ranging from 2-5 inches across the Region with some isolated totals nearing 8 inches mainly N and E of Metro Houston. It is still too soon to know with any certainty exactly where and what neighborhoods the heavier rainfall may occur, so we encourage everyone to monitor the updates daily as additional information/data becomes available.

[srainhoutx]

The afternoon updated quantitative precipitation forecast for the next 7 days which takes us into the beginning of May suggests more unsettled weather could persist into the new Month. Also we are 40 days away from the beginning of Hurricane Season/2016 for the North Atlantic Basin and the ENSO update issued this morning suggests we are indeed well on the way to transitioning toward a La Nina pattern. Often during the transitioning of Global weather patterns we experience volatility with extended periods of unsettled weather. In the days ahead we will begin to focus on what potentials for Tropical Troubles could be ahead particularly for the Western Caribbean and the Gulf of Mexico. Look for a new Topic in the days ahead where we will attempt to outline what we may expect this Summer when all eyes turn to the Tropics.

Some of the wettest years happened in El Nino to La Nina years like 1973, 1983, and 2007. Floods occurred in the summer in 1973 and 2007.

[BlueJay]

I'm thinking about May flowers with just enough rain to keep them alive...

[srainhoutx]

Starting to get a bit concerned that a pesky frontal boundary may linger across SE Texas as we begin May and head into early next week. The 12Z GFS is suggesting some locations may see near 6 inches of rainfall where it is not needed. This includes the Friday and Saturday timeframe, but if the GFS is correct additional heavier rainfall could regenerate late Sunday into Tuesday of next week. We will need to watch the latest trends to see if this pesky upper pattern continues to send impulses across our area into next week.

[wxman57]

I'm not seeing much change to the overall weather pattern across the southern U.S. through the next couple of weeks. Chance of more heavy rain on Saturday, but nothing like last week's flood.

[srainhoutx]

The 12Z GFS suggests generally 1 to 3 inches of additional rainfall may be possible Sunday through Tuesday.

...THERE IS A MRGL RISK OF SVR TSTMS FROM CNTRL TX NEWD ACROSS THE
OH RIVER...

...SUMMARY...
SCATTERED STRONG TO SEVERE STORMS ARE POSSIBLE FROM PORTIONS OF
TEXAS INTO THE OHIO VALLEY WITH A THREAT OF HAIL AND WIND.

...SYNOPSIS...
A BELT OF STRONG SWLY FLOW ALOFT WILL EXTEND FROM THE SRN PLAINS
INTO THE NERN STATES WITH TWO LOW-AMPLITUDE WAVES. ONE WILL MOVE
FROM IL/IN EWD ACROSS THE OH VALLEY LATE IN THE AFTERNOON THROUGH
EVENING WITH A WEAK SFC LOW ACROSS THE AREA. TO THE SW...AN INVERTED
SFC TROUGH WILL EXIST FROM THE LOWER RIO GRANDE VALLEY INTO SERN TX
AND LA...WITH SUBSTANTIAL MOISTURE AND INSTABILITY IN PLACE.
MEANWHILE...A POLAR AIR MASS WILL CONTINUE TO SURGE SWD OVER WRN
TX...WITH THE LEADING FRONT THROUGH ALL BUT FAR SERN TX BY MON
MORNING. THE RESULT WILL BE A RELATIVELY LARGE AREA OF ISOLATED
SEVERE THUNDERSTORM POTENTIAL FROM LATE AFTERNOON INTO THE EVENING.


...CNTRL INTO SERN TX...
NEUTRAL TO RISING HEIGHTS ALOFT WILL EXIST WITH MODESTLY STRONG MID
TO UPPER LEVEL FLOW PERSISTING OVER THE REGION. WEAK CONVERGENCE
WILL EXIST OVER MUCH OF ERN TX INTO WRN LA AS SELY SFC WINDS BRING
TROPICAL MOISTURE FARTHER INLAND. HEATING WILL LEAD TO STRONG
INSTABILITY WITH MLCAPE OF 2000 TO PERHAPS 3000 J/KG. SOME MODELS
INCLUDING THE ECMWF PRODUCE A SUBSTANTIAL AREA OF THUNDERSTORMS
ACROSS MUCH OF CNTRL TO ERN TX DURING THE EVENING...APPROACHING THE
TX COAST BY MON MORNING. GIVEN RATHER WEAK FORCING AND POTENTIAL FOR
CAPPING AHEAD OF THE FRONT...WILL DEFER ANY POTENTIAL SLIGHT RISK TO
LATER OUTLOOKS. LONG STRAIGHT LINE HODOGRAPHS...STEEP LAPSE RATES
ALOFT AND AMPLE MOISTURE WILL CONDITIONALLY FAVOR LARGE DAMAGING
HAIL.

Early morning moisture returns to SE Texas from the Gulf. Scattered showers and thunderstorms are developing from Galveston Bay on E into Beaumont/Lake Charles and into Arcadia of Louisiana where heavy training rainfall is occurring.

We have a weak frontal boundary just to the NW of Metro Houston and a combination of the seabreeze and the stationary frontal boundary could lead to additional showers and storms to develop with daytime heating roughly from Victoria on NE.

An incoming disturbance embedded in the sub tropical jet may provide some lift later this afternoon and evening further enhancing storm development. No clear cut solutions on the who, where and how much rainfall we could see, but as HGX mentions...will need to monitor developments throughout the next 24 hours or so particularly along and N of I-10 across the Metro Region where additional heavy rainfall could pose minor street flooding.

508 AM EDT SUN MAY 01 2016

AREAS AFFECTED...FAR SE TX...SW LA...CENTRAL LA...SW MS

CONCERNING...HEAVY RAINFALL...FLASH FLOODING LIKELY

VALID 010908Z - 011438Z

SUMMARY...MODELS SIGNAL LOCALLY VERY HEAVY RAINFALL THIS MORNING.
GREATEST CONFIDENCE LIES IN CENTRAL LA TO SOUTHWEST MS...THOUGH A
SECOND MAXIMUM MAY OCCUR NEAR THE TX/LA COAST. FLASH FLOODING
LIKELY.

DISCUSSION...MODELS HAVE SIGNALED VERY HEAVY RAIN...EVEN IN THE
WAKE OF EXTENSIVE OVERTURNING THAT OCCURRED SATURDAY.
OBSERVATIONAL TRENDS LEND INCREASING CONFIDENCE THAT A FLASH FLOOD
THREAT WILL DEVELOP THIS MORNING. SURFACE TO 850 MB FLOW WAS
FAIRLY WEAK...BUT WARM ADVECTION ALONG THE NORTH SIDE OF A PW
MAXIMUM OVER THE GULF...HAD YIELDED SCATTERED CONVECTIVE
INITIATION OVER TX/LA BY 09Z. FLOW IN THE VERY LOW LEVELS IS
FORECAST TO REMAIN TAME...BUT GEFS ANOMALIES DO INDICATE RATHER
ANOMALOUS SOUTHERLY 700 MB FLOW CENTERING ON LOUISIANA THIS
MORNING...WITH RAP FORECAST SOUNDING INDICATING STRONG WARM
ADVECTION ROUGHLY IN THE 800-600 MB LAYER. PRECIPITABLE WATER WAS
RISING TOWARD 1.7 TO 1.9 INCHES WITH MODERATE MIXED LAYER CAPE
WELL OVER 1000 J/KG. THIS ENVIRONMENT WILL FAVOR VERY EFFICIENT
RAINFALL...SUPPORTING THE NOTION IN THE HI-RES MODELS THAT SPOT
AMOUNTS OF 4 OR MORE INCHES ARE LIKELY TO OCCUR...AND ISOLATED
EXTREME TOTALS ABOVE 7 INCHES ARE POSSIBLE.

THE MAIN UNCERTAINTY IS WHERE THE EVENT WILL FOCUS. ONLY ABOUT
HALF OF THE GUIDANCE GENERATES INTENSE RAIN FROM THE EAST SIDE OF
HOUSTON INTO SW LA...WHERE ORGANIZATION WILL BE MORE DEPENDENT ON
ESTABLISHING A COLD POOL. A LITTLE GREATER CONFIDENCE EXISTS FROM
CENTRAL LA TO SW MS...WHERE THE RAP HAS COME INTO SYNC WITH GLOBAL
GUIDANCE IN PREDICTING A PERSISTENT AXIS OF 250 MB DIVERGENCE AND
ASSOCIATED DEEP LAYER LIFT. THE HRRR ALSO SHIFTED ITS HEAVY RAIN
SIGNAL INTO THIS REGION. AT 09Z...HOWEVER...RADAR TRENDS SUGGESTED
THAT A COLD POOL MAY INDEED BECOME ESTABLISHED BACK OVER
TX/LA...SUCH THAT A PRONOUNCED FLASH FLOOD THREAT EXISTS
THROUGHOUT THE MPD AREA. FFG WILL QUICKLY BE EXCEEDED ALONG THE
TX/LA COAST...WHERE ANTECEDENT CONDITIONS ARE THE WETTEST.

AREAS AFFECTED...UPPER TX COAST...SOUTHERN LA

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

VALID 011430Z - 011900Z

SUMMARY...BACKBUILDING AND TRAINING CONVECTION WILL BE A CONCERN
OVER THE NEXT FEW HOURS ALONG THE FAR UPPER TX COAST AND ACROSS
FAR SOUTHERN LA. GIVEN RECENT HEAVY RAINFALL...ADDITIONAL FLASH
FLOODING WILL BE POSSIBLE.

DISCUSSION...SEVERAL COLD-TOPPED AND VERY SLOW MOVING CONVECTIVE
CLUSTERS OVER SOUTHERN LA ARE LIKELY TO PERSIST THROUGH
MID-AFTERNOON WHILE GRADUALLY CONSOLIDATING AND SETTLING OFF TO
THE SOUTHEAST. IN FACT...SURFACE OBSERVATIONS SHOW A RATHER
WELL-DEFINED COLD POOL IN RESPONSE TO THE CONVECTIVE
ORGANIZATION...AND THIS IS ALLOWING FOR AN OUTFLOW BOUNDARY TO
GRADUALLY BOW OUT IN AN ANTICYCLONIC FASHION. THE SOUTHERN FLANK
OF THE OUTFLOW BOUNDARY IS FOCUSING STRONG CONVECTION WITH SLOW
MOVEMENT AND VERY HEAVY RAINFALL RATES...AND THIS IS WHERE THE
CONCERN WILL BE OVER THE NEXT FEW HOURS.

ENHANCED MOISTURE CONVERGENCE ALONG THIS BOUNDARY INVOLVING THE
UPPER TX COAST AND SOUTHERN LA WILL BE INTERACTING WITH A
MODERATELY UNSTABLE AIRMASS ADVECTING NORTH IN OFF THE NORTHERN
GULF OF MEXICO. MLCAPE VALUES ARE ALREADY LOCALLY OVER 2000
J/KG...WITH PWATS OVER THIS AREA OF 1.7 TO 1.8 INCHES. THIS IS
EXPECTED TO RESULT IN AN ENVIRONMENT CONDUCIVE FOR BACKBUILDING
AND TRAINING CONVECTION AT LEAST OVER THE NEXT FEW HOURS.

EXPECT RAINFALL RATES OF 2 TO 2.5 INCHES/HR WITHIN THE STRONGER
CONVECTIVE CORES AND ESPECIALLY WITH ANY OVERSHOOTING TOPS. SOME
OVERSHOOTING TOPS HAVE BEEN VALIDATED BY THE GOES-OTD ALGORITHM
NOT FAR SOUTH OF BATON ROUGE OVER THE LAST 30 MINUTES.

ADDITIONAL STORM TOTAL RAINS OF 3 TO 5 INCHES WILL BE POSSIBLE
THROUGH 19Z. CONSIDERING THE RECENT HEAVY RAINFALL ACROSS THE
THREAT AREA...ADDITIONAL FLASH FLOODING AND/OR RUNOFF PROBLEMS
WILL BE POSSIBLE.

Locally we are begging to see some developing showers and thunderstorms possibly organizing across Brazoria, Ft Bend, Galveston and Chambers Counties. Gulf moisture is showing some sign of lifting N as an upper air disturbance spins over Arizona/New Mexico. There are signs that another disturbance is crossing Mexico embedded in the sub tropical Jetstream.

The latest NAM model is indicating the potential of a couple of inches of rainfall today. We can handle an inch or two across Metro Houston, but further East up to 9 additional inches of rain may be possible...if the 12Z NAM is correct.

[jasons2k]

The location of that front is going to be very important in deciding where training sets up later today. From Galveston Bay eastward, it's stationary. To the SW, you can see it edging very slowly to the coast still. It's just now crossing LBX (Lake Jackson/Angleton Apt. off 288) but it is slowly a lot. If that front pulls back north later today, we need to watch out, big time.

[jeff]

still a good cap to overcome. Never turn your back on a boundary in a tropical air mass...but capping continues to hold convection down. Vis satellite shows increasing breaks...but not sure we will be able to break the cap. Meso guidance not very excited about convection.

AREAS AFFECTED...UPPER TX COAST...SOUTHWEST LA

CONCERNING...HEAVY RAINFALL...FLASH FLOODING LIKELY

VALID 011855Z - 012245Z

SUMMARY...ADDITIONAL REPEATING SHOWERS AND THUNDERSTORMS POSSIBLE
THROUGH THIS AFTERNOON. GIVEN THE VERY WET ANTECEDENT
CONDITIONS...FLASH FLOODING WILL REMAIN A CONCERN.

DISCUSSION...A WELL-DEFINED AND CONVECTIVELY INDUCED OUTFLOW
BOUNDARY HAS BEEN SETTLING SLOWLY SOUTH OUT INTO THE IMMEDIATE
OFFSHORE WATERS OF SOUTHERN LA. HOWEVER...THE WESTERN END OF THIS
BOUNDARY EXTENDS BACK TO THE UPPER TX COAST. STRONG CONVECTION
CONTINUES TO FOCUS ALONG THE BOUNDARY AND ALSO IN AN ELEVATED
FASHION NORTH OF IT ALONG THE SOUTHERN LA COAST.

THE RAP MOISTURE FLUX CONVERGENCE IS A BIT STRONGER ALONG THE
UPPER TX COAST AND INTO SOUTHWEST LA...AND A NOSE OF MODERATE
INSTABILITY WITH MLCAPE VALUES OF 2000 TO 2500 J/KG ARE FOCUSING
IN ON THE WESTERN AND SOUTHWEST FLANK OF THE OUTFLOW BOUNDARY.
MEANWHILE...A SPLIT UPPER JET PATTERN REMAINS IN PLACE WITH
NOTABLY DIFFLUENT FLOW ALOFT PERSISTING AND HELPING TO SUSTAIN
STRONGER UPDRAFTS.

THE BULK OF THE STRONGER CONVECTION OVER THE NEXT FEW HOURS WILL
GENERALLY TEND TO FOCUS OVER THE OFFSHORE WATERS JUST SOUTH OF
LA...HOWEVER...THERE IS SUFFICIENT FORCING AND MOIST/UNSTABLE LOW
LEVEL FLOW INTERCEPTING AND OVERRUNNING THE BOUNDARY SUCH THAT
CONVECTION WILL TEND TO PERSIST A BIT LONGER OVER THE UPPER TX
COAST AND ADJACENT AREAS OF ESPECIALLY SOUTHWEST LA.

CONSEQUENTLY...THE THREAT FOR FLASH FLOODING CONTINUES HERE...WITH
RAINFALL RATES THAT MAY REACH OR EXCEED 2 INCHES/HR...AND YIELDING
ADDITIONAL AMOUNTS THROUGH THE LATE AFTERNOON OF 3 TO 6 INCHES.

AREAS FARTHER DOWNSTREAM TOWARD SOUTHEAST LA SHOULD BECOME
STABILIZED ENOUGH FOR THE HEAVY RAINFALL THREAT TO GRADUALLY
DIMINISH AT LEAST FOR THE MID TO LATE-AFTERNOON HOURS AS THE MAIN
CONVECTIVE FOCUS WILL SHIFT FARTHER SOUTH AND EAST AND OUT OVER
THE WATER.

Sunday afternoon briefing from Jeff:

Yet another complicated forecast for the region over the next 24-36 hours….

Tremendous flash flood event ongoing over SW LA where 8-12 inches of rain has fallen today around/SE of Lake Charles. This activity has produced a sprawling meso high which is slowly shifting an outflow boundary WSW/SW over the northern Gulf waters south of Sabine Pass. Extending WSW/SW from this outflow boundary is a stalled weak trough axis which has been the focuses for showers today over the coastal sections of SE TX. Upper air divergence if strong over far SE TX on the western edge of backbuilding flash flooding thunderstorms over the extreme N Gulf and south LA coastal marshes. 12Z CRP sounding showed a strong capping inversion in place over the coastal bend which has likely held convection back over the stalled coastal boundary over SE TX. Low level cloud deck is also preventing strong surface heating and thus the cap is maintaining a lid on convection thus far. An upper air disturbance approaching from the west will spread large scale ascent toward the region later this afternoon into tonight.

Main question going forward is can the capping inversion be overcome either by enough surface heating or incoming lift from the west. There are certainly plenty of boundaries in place to focus convection if the cap is broken and overall storm motions have been very slow. Upper air winds really are not that divergent over SE TX…maybe Chambers and Liberty Counties where stronger cells have fired today on the stalled boundaries.

Short term models are really not very aggressive in developing much along the boundaries over the region…they are suggesting the capping holds. Looking at current satellite loops and actual cloud formations outside show very little vertical development thus far.

Not sure the capping will be overcome…so will just have to watch radar trends closely the next several hours.

If storms are able to organize very heavy rainfall will be possible as seen over SW LA today, although moisture levels do decrease from east to west over SE TX. Still could easily see a quick 1-3 inches with any stronger storms that develop. Will favor any develop along and SE of a line from Liberty to SE Houston to Freeport where several boundaries are in place and upper air divergence is greatest.

Area should finally get a decent break in the active weather Tuesday-Friday with a ridge of high pressure building into the state from the NW with blocking lows over the east coast and SW US. Active pattern set to return next weekend as large upper level system over the SW US begins to edge toward TX. This looks like another slow moving upper level system….still plenty of time to watch for both severe and heavy rainfall threats next weekend into early the following week.

655 PM EDT SUN MAY 01 2016

AREAS AFFECTED...WESTERN LA AND SOUTHEAST TX

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

VALID 012254Z - 020254Z

SUMMARY...THUNDERSTORMS WITH HEAVY RAIN ARE OCCURRING OVER
SATURATED SOILS. FLASH FLOODING REMAINS POSSIBLE.

DISCUSSION...THERE ARE TWO FOCI FOR CONVECTIVE DEVELOPMENT: A
STATIONARY FRONT IN THE PINEY WOODS AND BIG THICKET OF EAST TX
DOWN TOWARDS HOUSTON (NEAR THE APPARENT CAP EDGE) AND A STATIONARY
FRONT-LIKE FEATURE IN THE GULF OF MEXICO WITH CIN ALONG IT.
SOUTHEAST FLOW AT 20 KTS IS OVERRIDING THE STATIONARY FRONT IN THE
GULF AND CONTINUING TO CAUSE FRAGMENTS OF CONVECTION ACROSS
SOUTHWESTERN LA AND NEAR HIGH ISLAND TX. THE STATIONARY FRONT IN
EASTERN TX HAS BEEN LIGHTING UP WITH NEW ACTIVITY DURING THE PAST
COUPLE HOURS, AND RAIN RATES THERE ARE INCREASING. MLCAPES ALONG
THE EAST TX BOUNDARY ARE 2000 J/KG WHILE MUCAPES OF 1000+ J/KG LIE
OFFSHORE THE LA COAST. PRECIPITABLE WATER VALUES ARE 1.50-1.75".

THE 18Z NAM CONEST AND RECENT RUNS OF THE HRRR AND EXPERIMENTAL
HRRR HAVE AN IDEA REGARDING ACTIVITY IN EASTERN TX, THOUGH NONE OF
THE GUIDANCE IS A FAN OF ACTIVITY CONTINUING IN SOUTHWEST LA.
EVEN SO, BELIEVE CONVECTION REMAINS POSSIBLE INTO THE OVERNIGHT
HOURS, UNTIL LOW-LEVEL INFLOW DECREASES FURTHER AROUND 03Z PER
RECENT RAP RUNS. CONVECTION ALONG THE BOUNDARY IN EASTERN TX WILL
HAVE PROBLEMS FORWARD PROPAGATING TO THE EAST DUE TO SOUTHEAST 850
HPA INFLOW -- IT COULD REMAIN QUASI-STATIONARY. HOURLY RAIN RATES
UP TO 2", WITH LOCAL AMOUNTS OF 3-5", ARE POSSIBLE IN THIS REGION,
THOUGH MORE LIKELY NEAR THE CENTRAL TX/LA BORDER. IN AN AREA
SATURATED BY RECENT RAINS, FLASH FLOODING REMAINS POSSIBLE.
