AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1035 AM CST FRI DEC 19 2014

.DISCUSSION...
CANNOT REALLY FIND A REASON TO CHANGE INHERITED GRIDS/ZONES THIS
MORNING. LOCAL 88DS SHOW WIDESPREAD RAINFALL CONTINUING TO COVER
MOST OF THE FORECAST AREA THANKS TO A DEVELOPING AREA OF LOW
PRESSURE OVER THE NWRN GULF...AN ASSOCIATED WARM FRONT INCHING NWD
ALONG THE COAST...AND DECENT OVERRUNNING AHEAD OF AN APPROACHING
SHORTWAVE ALOFT. DID ADJUST THE MAX TEMPS JUST SLIGHTLY ACROSS OUR
NRN ZONES WHERE TEMPS HAVE CREPT ABOVE INHERITED MAXES...BUT
ADDITIONAL WARMING LOOKS MINIMAL GIVEN ALL THE CLOUDS/RAIN.
OTHERWISE NO CHANGES.

PREV DISCUSSION... /ISSUED 414 AM CST FRI DEC 19 2014/

DISCUSSION...
A WARM FRONT IS DRAPED OVER COASTAL WATERS OF SOUTHEAST TEXAS AND
SOUTHERN LOUISIANA THIS MORNING. A SURFACE LOW OVER DEEP SOUTH
TEXAS WILL TRACK TO THE NORTH ALONG THIS FRONT AND INTO THE
LOUISIANA COASTAL WATERS. SHOWERS AND ISOLATED THUNDERSTORMS WILL
CONTINUE ON AND OFF INTO THE AFTERNOON HOURS. RAINS WILL BE HEAVY
AT TIMES ALONG AND NORTH OF THE I-10 CORRIDOR. RAINFALL TOTALS
WILL RANGE FROM TWO TO FOUR INCHES WITH ISOLATED AMOUNTS AROUND
FIVE TO SIX INCHES. THIS MAY CAUSE SOME MINOR FLOODING ISSUES IN
THE NORMALLY LOW LYING LOCATIONS AROUND THE REGION. TEMPERATURES
ARE NOT EXPECTED TO RISE ALL THAT MUCH AS RAINS WILL COOL THE
ATMOSPHERE. THE SURFACE LOW IS EXPECTED TO MOVE EAST OF THE
REGION BY THIS EVENING WITH A COLD FRONT FOLLOWING IN ITS WAKE.
THIS WILL SHUT DOWN THE RAINS BY LATE THIS EVENING. OVER NIGHT
LOWS WILL DROP BACK INTO THE 40S FOR THE START ON SATURDAY. SKIES
WILL BE SLOW TO CLEAR...THEREFORE AFTERNOON TEMPS ARE EXPECTED TO
TOP OUT IN THE MID TO UPPER 50S. SUNDAY WILL BE A REPEAT OF
SATURDAY. RAINS RETURN BACK ON TUESDAY.

FOR THOSE LOOKING TOWARDS CHRISTMAS... MOSTLY CLEAR SKIES...A
COOL START TO THE DAY WITH AFTERNOON TEMPERATURES EXPECTED TO THE
MID 60S.
