AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
256 PM CDT THU APR 15 2010

.DISCUSSION...
MOISTURE...IN ADDITION TO A LARGE AREA OF RAIN...CONTINUES TO SPREAD
NORTHWESTWARD FROM SOUTH TEXAS AND THE LOWER RIO GRANDE RIVER
THROUGH WEST TEXAS AND THE TEXAS PANHANDLE THIS AFTERNOON ALONG AND
TO THE EAST OF A WEAK UPPER LEVEL TROUGH.  RADAR IMAGERY INDICATED
TWO MESOSCALE CONVECTIVE VORTICES OVER THE UPPER AND LOWER TRANS
PECOS THIS AFTERNOON...SWIRLING SLOWLY NORTHWESTWARD.  EXPECT THE
PRECIPITATION TO PERSIST THROUGH THE AFTERNOON...AND OVERNIGHT AS A
LOW LEVEL JET INCREASES...AND THE SAID VORTICES CONTINUE OVER THE
AREA.  RAINFALL COULD BE HEAVY AT TIMES...OVER ONE INCH PER HOUR...
SO WILL LEAVE THE FLASH FLOOD WATCH ISSUED EARLIER INTACT AS THESE
AREAS STILL APPEAR TO BE THE FAVORED FOR ANY HEAVIER PRECIPITATION.
WE COULD ALSO SEE WIDELY SCATTERED THUNDERSTORMS OVER THE HIGHER
TERRAIN THIS AFTERNOON AND EVENING WHERE SOME HEATING IS OCCURRING.
AN ISOLATED STORM OR TWO COULD BECOME SEVERE WHERE INSTABILITY MAXES
OUT...BUT A WIDESPREAD SEVERE THREAT DOES NOT APPEAR IN THE OFFING
DUE TO A LACK OF SHEAR.

THE SAME UPPER TROUGH MAY LINGER OVER EASTERN PORTIONS OF THE CWA
FRIDAY...WHILE A COLD FRONT IS PROGGED TO SETTLE SOUTH INTO THE
REGION IN THE WAKE OF AN UPPER TROUGH THAT WILL BE MOVING OVER THE
GREAT LAKES.  HAVE CARRIED THE BEST CHANCE OF RAIN OVER THE WESTERN
LOW ROLLING PLAINS FRIDAY WHERE RAIN MAY PERSIST FROM TONIGHT...OR
REFORM ALONG THE SAID BOUNDARY FRIDAY AFTERNOON.  SOME PORTIONS OF
THE FLASH FLOOD WATCH MAY HAVE TO BE EXTENDED DEPENDING ON THE
PROGRESS OF THE UPPER TROUGH...AND FRONT.  THE EMPHASIS FOR BETTER
PRECIPITATION CHANCES WILL SHIFT TO THE HIGHER TERRAIN FRIDAY NIGHT
AS UPSLOPE FLOW COMMENCES BEHIND THE SOUTHWARD PUSHING FRONT...AND
ANOTHER WEAK UPPER TROUGH WOBBLES EASTWARD ACROSS THE DESERT
SOUTHWEST.  IN FACT...RAIN CHANCES WILL CONTINUE THROUGH THE WEEKEND
AS AT LEAST WEAK UPPER LEVEL TROUGHING AND DIFFLUENT FLOW ALOFT
PERSISTS OVER THE REGION.  MAX TEMPERATURES WILL LIKELY REMAIN BELOW
NORMAL THROUGH THE WEEKEND...WHILE MIN TEMPERATURES WILL BE ABOVE.

ANOTHER UPPER TROUGH WILL IMPINGE UPON THE AREA EARLY NEXT WEEK AND
BRING MORE CHANCE FOR RAIN.  PROGS ARE UNDECIDED WHETHER THIS TROUGH
WILL STAY AROUND...OR MOVE TO THE EAST BY TUESDAY.  THEREFORE...HAVE
KEPT AT LEAST A SLIGHT CHANCE OF SHOWERS AND STORMS THROUGH
MIDWEEK.  YET ANOTHER...DEEPER UPPER TROUGH COULD FORM OVER THE
WESTERN CONUS BY MIDWEEK THEN HEAD FOR THE REGION.  THERE MAY BE A
BREAK IN PRECIPITATION CHANCES...BUT IT DOE NOT APPEAR IT WILL LAST
LONG.
