[kayci]

In Brazoria Co. (Alvin) will I be impacted?????

kayci, Brazoria County as well as all of SETexas need to keep p with the latest weather trends. I have been busy activating several new member accounts as more folks join our Region Weather Community.

Srain, I appreciate you! Thank you!

Another update from Jeff:

SPC has issued a tornado watch until 900am for a large part of SE TX and the coastal bend.

 

Torandic supercell has rotated through Wharton and Fort Bend Counties producing numerous funnel clouds and damage near Hungerford. Cell is now over W Harris County and has weakened, but could still cycle through and go tornadic again. This cell is producing extremely heavy rainfall of 1.5-3.0 inches per hour and the threat may be quickly transitioning to excessive rainfall.

 

Further SW a line of storms extends from the lead supercell to northern Jackson County along the leading edge of well defined cold pool. Air mass over the coastal plains has warmed into the lower 80’s and speed shear is enhanced near the low level boundary making tornado production possible. Thus far no additional cell except the Fort Bend County storms have shown rotation, but the environment is becoming more favorable with the modest heating we have seen today.

 

Next rounds is blowing up across NW TX at this time and expect this activity to arrive into SE TX toward Tuesday morning. Likely the first of several rounds of severe weather and heavy rainfall over the next 3-4 days.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
404 PM CDT MON MAY 26 2014

.DISCUSSION...
PROPAGATION OF THE OVERNIGHT PCPN THROUGH SE TX THIS AFTN LIKELY
HELPED BY SPLITTING JET ALOFT/INFLUX OF ABUNDANT LOW-LEVEL MOIST-
URE FROM THE GULF. SAVE FOR THE LEADING TSRA (WHICH PROMPTED THE
WARNINGS) THE REST OF THE ACTIVITY SHOULD CONTINUE TO BE GENERAL-
LY MODERATE/HEAVY RAINFALL PRODUCERS. NOT SEEING MUCH BEHIND THE
SYSTEM...SO WITH THE LOSS OF DAYTIME HEATING WILL EXPECT A BREAK
OVERNIGHT. BUT PER WV IMAGERY ADDITIONAL DISTURBANCES SEEM TO BE
HEADED THIS WAY.

AND SO...THE FCST FOR THE NEXT FEW DAYS SHOULD REMAIN ON THE ACT-
IVE SIDE WITH THE SLOW APPROACH/POSSIBLE STALLING OF THE MAIN UP-
PER LOW OVER SE TX. MOST NOTICEABLE DIFFERENCES FOR THE 12Z RUNS
SEEM TO BE WITH THE END OF PCPN CHCS...WHICH COULD EXTEND TO SAT.
OTHERWISE NOT TOO MANY CHANGES WITH THE GRIDS AS MODELS ARE/HAVE
BEEN HANDLING THIS SYSTEM RATHER CONSISTENTLY. GIVEN THE PROGGED
DYNAMICS AND ONGOING TRENDS THE FCST OF POSSIBLE SEVERE WX/HEAVY
RAINS FOR THE NEXT COUPLE OF DAYS LOOK REASONABLE AT THIS POINT.

Excessive rainfall ongoing over western Harris County. HCFCD gage at US 90 and Buffalo Bayou has recorded over 3.0 inches in the last hour. An additional 1-2 inches of rainfall is likely as cells continue to train NNE across western Harris County.

Currently raining nicely IMBY. Only .40 inches so far but it looks like that amount is fixing to at least double soon. I hope everyone is having a nice Memorial Day.

It looks like a new MCS is developing across NW Texas and storms are again firing W of the Rio Grande. Also new storms are forming across the Hill Country along an outflow boundary. You folks S and E of DT Houston hang on. Remember the forecast yesterday did not expect much to anything across Houston today. It was expected for Tuesday. We have at least 72 to 96 hours or more before this system finally relaxes and moves away.
