.DISCUSSION...
SEE AVIATION SECTION.

&&

.AVIATION...
WIDESPREAD AREA OF LIGHT RAIN EXTENDS FROM THE RIO GRANDE TO
NORTHEASTERN COUNTIES. OFF AND ON LIGHT RAIN WILL CONTINUE AT THE
TERMINALS FOR THE NEXT FEW HOURS. CIGS WILL BE VFR AND VIS WILL
REMAIN UNLIMITED AS RAIN IS VERY LIGHT. RAIN WILL END SOONER AT
DRT...BY 20Z. CIGS WILL REMAIN VFR OVERNIGHT. TOMORROW THERE IS A
CHANCE FOR REPEAT OF RAIN AND HAVE INCLUDED PROB30 FOR THE 12Z-18Z
PERIOD. NOT CLEAR ENOUGH AT THIS TIME TO GET MORE SPECIFIC.

&&

.PREV DISCUSSION... /ISSUED 855 AM CDT WED SEP 23 2009/

UPDATE...
FORECAST UPDATED TO INCREASE POPS FOR THIS MORNING GIVEN CURRENT
RADAR TRENDS. ISOLATED THUNDER WAS ADDED TO THE NE COUNTIES AND MAX
TEMPERATURES WERE ALSO ADJUSTED DOWN A CATEGORY OR TWO DUE TO
INCREASED RAIN CHANCES AND CLOUD COVER.

PREV DISCUSSION... /ISSUED 428 AM CDT WED SEP 23 2009/

DISCUSSION...
AN UPPER LOW WILL MEANDER AROUND THE CENTRAL HIGH PLAINS TODAY AND
THURSDAY. AN AREA OF RAIN WITH EMBEDDED ISOLATED SHOWERS ACROSS
THE RIO GRANDE PLAINS INTO THE HILL COUNTRY IS DUE TO AN UPPER
LEVEL SPEED MAX. THIS FEATURE MOVES ACROSS SOUTH CENTRAL TEXAS
TODAY WITH HIGH CHANCES OF RAIN. OCCASIONAL LIGHTNING STRIKES HAVE
BEEN NOTED, HOWEVER WILL LEAVE MENTION OF THUNDER OUT OF FORECAST
AS TOO ISOLATED. EXPECT MOSTLY LIGHT TO MODERATE RAINFALL TODAY.
ANOTHER UPPER LEVEL SPEED MAX/SHORT-WAVE MOVES ACROSS SOUTH
CENTRAL TEXAS ON THURSDAY WHILE A NORTHWARD MOVING 850 MB FRONT
INCREASES ISENTROPIC LIFT AND HAVE INCREASED POPS TO LIKELY ALONG
WITH HIGHER RAINFALL AMOUNTS. THE UPPER LOW MOVES EAST INTO THE
PLAINS FRIDAY TO THE LOWER MISSOURI VALLEY SATURDAY. A TAILING
TROUGH WILL PRODUCE MAINLY SLIGHT CHANCE POPS ACROSS CENTRAL AND
EASTERN AREAS ON FRIDAY AND ONLY EASTERN AREAS ON SATURDAY. WEAK
UPPER LEVEL RIDGE WILL LEAD TO NO POPS ON SUNDAY. MODELS THEN
DIVERGE FOR MONDAY AND TUESDAY OF NEXT WEEK. THE GFS AND NOGAPS
GENERATE AN UPPER LOW OVER NORTHEASTERN MEXICO THAT MOVES ACROSS
SOUTHERN TEXAS WHILE THE ECMWF AND CANADIAN MAINTAIN A WEAK UPPER
LEVEL RIDGE. THE GFS/NOGAPS WOULD BE WET AND THE ECMWF/CANADIAN
WOULD BE DRY. FOR NOW, WILL RETAIN ONLY SLIGHT CHANCE POPS FOR
FAR SOUTHERN AREAS. HOPEFULLY, FUTURE MODEL RUNS WILL COME TO A
CONSENSUS. MAV/MEX TEMPERATURE GUIDANCE SEEMS REASONABLE AND WILL
GENERALLY FOLLOW.
