June 2017: Typical Summertime WX To End Month

[srainhoutx]

Saturday morning Update from Jeff:

Flash Flood Warning for NE Harris County around Lake Houston until 1100am.

Isolated excessive rainfall occurring across portions of Harris County this morning. Lake Houston Dam has recorded 5.96 inches of rainfall in the last 3-4 hours from slow moving to at times stationary storms. Influx of deep Gulf moisture is combining with an approaching frontal boundary from the north to produce widespread showers and thunderstorms. Storm motions at times have been extremely slow to nearly stationary and rainfall rates in the strongest cells have averaged 1.5-3.0 inches per hour. Activity will continue to slowly sag southward and the atmosphere will gradually stabilize by late morning likely leading to decreasing coverage of storms.

Main threats this morning will be street flooding where intense localized rainfall develops.

Another active day on Sunday with similar conditions in place.

Conditions continue to deteriorate as boundary collisions are occurring along the HWY 105 area. Getting a bit concerned that flooding issues may increase across potions of Waller/Montgomery/Harris/Austin/Fort Bend/Liberty Counties as rainfall rates of near 2 inch per hour are increasing. I would not be surprise to see additional Flood Warnings/Advisories coming shortly.

Hope they move, instead of stall out. Like North!

We're caught in no man's land between the Hwy 105 and south sea breeze showers and the DFW MCV. CLL would use some rain after Cindy teased us and moved on...

We're right along the front...yet nothing.

I's been raining most of the morning here in Stafford. Currently a light rain, hearing some thunder here and there.

[TexasBreeze]

Already much more rain than from Cindy! The ghost of week ago Bret absorbed within the upper low to the south moving nw should keep things busy tonight and tomorrow!

HGX believes you folks in the Bryan/College Station area may see development before long. Convective temperatures are in the low 80's and with breaks in the clouds across your Region, thunderstorm activity may blossom before long. Fingers crossed!

Guess we better stay on our side of town. Have some errands to run.

Accumulations are mounting:

A line from Huntsville is expanding east, we may as Srain alluded get a piece of the pie soon.

Just a curious question. What are the odds of this stalled front drifting into GOM and causing a problem? Like an Alicia thing?

Doesn't look like any tropical mischief...for now. Hemispheric Patterns may be a bit more conducive for tropical development just beyond the 4th of July Holiday timeframe. But is for a different Topic.

MESOSCALE PRECIPITATION DISCUSSION 0394
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
353 PM EDT SAT JUN 24 2017

AREAS AFFECTED...SOUTHERN LA...SOUTHWEST MS...SOUTHEAST TX

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

VALID 241952Z - 242352Z

SUMMARY...SLOW MOVING SHOWERS AND THUNDERSTORMS WITH HEAVY
RAINFALL RATES ARE LIKELY TO PERSIST THROUGH THE REMAINDER OF THE
AFTERNOON HOURS. SOME LOCALIZED FLASH FLOODING IS POSSIBLE WITH
RAINFALL RATES ON THE ORDER OF TWO INCHES PER HOUR POSSIBLE.

DISCUSSION...RECENT IR SATELLITE IMAGERY HAS INDICATED EXPANDING
DEEP CONVECTION WITH EMBEDDED OVERSHOOTING TOPS. THE CONVECTION
IS ASSOCIATED WITH THE SLOW SOUTHWARD ADVANCE OF A COLD FRONT INTO
A VERY MOIST AND UNSTABLE AIRMASS OUT AHEAD OF IT AND IS BEING
FOCUSED NEAR A DEVELOPING WAVE OF LOW PRESSURE ALONG THE FRONT.
MIXED LAYER CAPE ON THE ORDER OF 2000 J/KG EXISTS JUST SOUTH OF
THE ONGOING CONVECTION, AND THIS UNSTABLE INFLOW TOWARDS THE FRONT
WILL SERVE TO ENHANCE RAINFALL RATES. THERE ARE ALSO INTERSECTING
OUTFLOW BOUNDARIES FROM EARLIER CONVECTION OVER THIS REGION.

A RIBBON OF HIGH PWS, ON THE ORDER OF 1.8 TO 2.2 INCHES PER THE
LATEST SPC MESOANALYSIS, IS POOLED ALONG AND AHEAD OF THE FRONT.
THIS IS FACILITATING RATHER EFFICIENT RAINFALL PROCESSES FOR
HEAVIER RATES, WHICH MAY APPROACH 2 INCHES PER HOUR AT TIMES THIS
AFTERNOON. THE LATEST HRRR EXPERIMENTAL GUIDANCE SUPPORTS SOME
IMPRESSIVELY HIGH RAINFALL TOTALS BETWEEN THE 20Z TO 00Z TIME
FRAME, WITH AMOUNTS LOCALLY UP TO 4 INCHES BY 00Z. THIS SEEMS TO
HAVE A BETTER HANDLE ON THE SITUATION THAN THE OPERATIONAL HRRR,
WHICH APPEARS TO BE UNDERDONE WITH ITS AMOUNTS. SOME FLASH
FLOODING WILL BE POSSIBLE GIVEN THESE TYPES OF RAINFALL AMOUNTS,
ESPECIALLY OVER AREAS THAT HAVE RECEIVED APPRECIABLE RAIN OVER THE
PAST FEW DAYS.

The afternoon Update 3 Day Quantitative Precipitation Forecast suggests and 1 to 2 inches may be possible into Tuesday. We'll need to watch Monday as a weak surface trough attempts to organize near Brownsville which may increase rainfall chances and that pesky frontal boundary as well as any meso/microoscale features that cannot be predicted beyond 3 to 5 hours pop up. I just emptied .92 of an inch out of the rain bucket which certainly beat the .38 of an inch I received for the Cindy 'event'. It is also 80F...I hit 100F yesterday, so the rainfall and cloud cover is appreciated.

[BlueJay]

No rain for us.
Zip. Zero. Zilch.
