June 2017: Typical Summertime WX To End Month

[srainhoutx]

Interesting Mid/Upper level feature in the Western Gulf is pulling the moisture from 93E into the Bay of Campeche increasing shower and isolated thunderstorm activity to its S and possibly Eastern flank later today. No tropical development is expected, but it adds to the complicate/complex forecast scenario ahead the next several days...

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.

1009 AM EDT SAT JUN 24 2017

AREAS AFFECTED...SOUTHEAST TX

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

VALID 241400Z - 241800Z

SUMMARY...VERY SLOW-MOVING SHOWERS AND THUNDERSTORMS WITH INTENSE
RAINFALL RATES MAY CAUSE SOME ADDITIONAL CONCERNS FOR RUNOFF AND
POSSIBLE FLASH FLOODING OVER THE NEXT FEW HOURS.

DISCUSSION...EXPERIMENTAL GOES-16 0.64 MICRON/VIS IMAGERY SHOWS AN
AGITATED CU/TCU FIELD ALONG THE IMMEDIATE MIDDLE AND UPPER TX
COAST...WITH NUMEROUS SMALL SCALE CLOUD STREETS ADVANCING
NORTHWEST IN CONJUNCTION WITH THE LOW LEVEL SOUTHEAST FLOW. THE
BOUNDARY LAYER IS RATHER UNSTABLE AND THE INTERACTION OF THIS WITH
AN OUTFLOW BOUNDARY A BIT FARTHER INLAND COUPLED WITH A VERY
DIFFLUENT UPPER AIR SIGNATURE IS ALLOWING CONVECTION TO EXPAND IN
COVERAGE.

CONVECTIVE CELL MOTION IS QUITE WEAK THOUGH WHICH IS ALLOW FOR
SOME HEAVY RAINFALL TOTALS. ALREADY THERE HAVE BEEN LOCALLY SOME 3
TO 4+ INCH AMOUNTS AROUND THE HOUSTON METROPOLITAN AREA...WHICH IS
BEING AIDED BY A VERY MOIST ENVIRONMENT WITH PWATS UP BETWEEN 2 TO
2.2 INCHES. THIS IS ENHANCING THE RAINFALL RATES WITH HIGHLY
EFFICIENT RAINFALL PROCESSES AT WORK.

EXPECT SOME ADDITIONAL RAINFALL AMOUNTS OF AS MUCH AS 2 TO 4
INCHES...WITH ISOLATED TOTALS POSSIBLE AS HIGH AS 6 INCHES WHERE A
FEW CELL MERGERS OCCUR AND TEND TO STALL GIVEN THE WEAK STEERING
FLOW/CELL MOTION.

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.

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.

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!
