.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE ON WATER VAPOR ACTUALLY SHOWED
UPPER LOW SLIGHTLY FURTHER WEST CENTERED IN JONES COUNTY TEXAS THIS
AFTERNOON COMPARED WITH 24HRS AGO.  ONE SMALL DIFFERENCE IS WEAKNESSES
UPSTREAM ARE A LITTLE CLOSER AND ACTUALLY BEGINNING TO HAVE AN EFFECT
OF NUDGING LOW EAST RECENTLY.  THAT IS GOOD NEWS FOR WATER WEARY CENTRAL
AND S CENTRAL TEXAS AS BLENDED TPW LOOP ALONG WITH LATEST GPS SITES AND
GOES SOUNDER PW LOOP NOW BEGINNING TO SEE SOME DRIER AIR FROM NM AND
NW AND EXT W TEXAS BEGINNING THEIR MOVE EAST.  BUT STILL WILL HAVE TO
BE CONCERNED WITH INSTABILITY AND LINGERING MODERATE MOISTURE CENTRAL
TEXAS SO ISOLATED HVY RAIN CELLS COULD STILL OCCUR AFTER 4PM CDT.
OBVIOUSLY MOST ACTION OCCURRING NOW IN SE TX...WITH NEXT BEST ACTION
INTERIOR E CENTRAL TX TO N CENTRAL TX INTO S CENTRAL
OKLAHOMA.  KEYING IN ON SE TX AS COLDEST CLOUDS TOPS...BEST MOISTURE
AND STRONGEST FORCING (OUTSIDE OF LOW TO THE WEST) OCCURRING HERE.
WILL BE CONCERNED WITH SLOW MOVING CELLS AS UPPER LEVEL WINDS AS LIGHT
AS YESTERDAY AND TRAINING CELLS AS CONVECTIVE CELLS FOLLOWING ALONG SWLY
FLOW AND MOST CONCERNED CENTERED FORT BEND/WHARTON ON THE SOUTH END
AND LIBERTY TO MONTGOMERY TO BRAZOS/GRIMES ON THE NORTH END AND THIS
INCLUDED THE HOUSTON AND HARRIS COUNTY METRO AREA WHERE PWS OF 2.1"
OR GREATER CAN RESULT IN 1-2.5" IN A 30 TO 75 MINUTE TIME THRU 2130Z.
ALSO EYEING WEAKER BUT STILL POTENT ORGANIZED HVY RAIN CELLS LIFTING
NORTH THRU N CENTRAL TEXAS VIC OF MCLENNAN TO TARRANT THAT IN ITS PATH
NORTH/NE COULD RESULT IN HVY RAIN BURSTS IN A SHORT TIME AND
S CENTRAL OK COULD GET THIS LATER ON.
WILL CONTINUE TO MONITOR AND GRAPHIC WILL BE ON THE WEB SHORTLY AT
ADDRESS BELOW...
.
ONE OTHER NOTE...LONGER LOOP OF MICROWAVE PW IN GULF OF MEXICO SHOWS A
SIZEABLE AMOUNT OF DEEP TROPICAL MOISTURE HEADING WNW THRU THE SE TO S
CENTRAL GULF OF MEXICO/YUCATAN AREA...NOT SURE WHAT RAMIFICATIONS THIS
HAS FOR THE LONGER RANGE.
