AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
245 PM CDT THU JUN 14 2007

.DISCUSSION...CONVECTION FIRING UP TODAY A LITTLE EARLIER WITH
LOWER CONVECTIVE TEMPS. ALSO SEEING MORE SEABREEZE BOUNDARY
ACTIVITY WITH DEVELOPMENT OF LOW LEVEL SOUTHERLIES. TRUE INLAND
SEABREEZE PENETRATION WILL BE LIMITED DUE TO NORTHERLY FLOW ALOFT...BUT
OUTFLOWS WILL ADVANCE WELL INLAND. GPS-IPW SHOWING ATMOSPHERE
RATHER SOUPY...RANGING FROM NEAR 2 INCHES AT BPT TO 1.7 INCHES AT
LFT...SO WITH SLOW THUNDERSTORM MOVEMENT CAN EXPECT ISOLATED
AREAS TO RECEIVE SUBSTANTIAL RAINS.

SYNOPTIC ANALYSIS CONTINUING TO SHOW AREA UNDER WEAK MID/UPPER LEVEL
RIDGING BETWEEN EAST COAST TROF AND CUT-OFF LOW SPINNING OVER NORTH
TEXAS/OKLAHOMA. LATEST GFS RUN WHICH HAS BEEN FAIRLY CONSISTENT
WITH OVERALL PATTERN LAST FEW DAYS SUGGESTING AT LEAST ONE MORE
DAY OF GOOD RAIN CHANCES BEFORE SOME DRIER AIR ALOFT IS PULLED IN
FROM TEXAS LOW.

GOOD RAIN CHANCES RETURN ONCE AGAIN FOR THE BEGINNING OF THE WORK-
WEEK AS TEXAS LOW IS PICKED UP BY NORTHERN STREAM SHORTWAVE WITH
COMBINED PHASED FEATURE PROGGED TO STALL ACROSS THE AREA.

&&

.AVIATION...A SLOW MOVING SEABREEZE WILL CONTINUE TO WORK NORTHWARD RESULTING IN
SHOWERS AND THUNDERSTORMS DEVELOPING THROUGH THE AFTERNOON HOURS.
VERY UNSTABLE CONDITIONS...ABUNDANT MOISTURE...COMBINED WITH SLOW
MOVEMENT...WILL RESULT IN HEAVY RAINFALL AND GUSTY SURFACE WINDS TO
40 MPH.

IN STRONG THUNDERSTORM AREAS THIS AFTERNOON...ABUNDANT CUMULUS FRACTUS WILL
RESULT IN CLOUD HEIGHT LESS THAN 500 FEET AND WINDS UP TO 40 MPH.
SMALL TO PENNY SIZE HAIL IS POSSIBLE. ELSEWHERE...SCATTERED TO
BROKEN CUMULUS WILL COVER THE REST OF THE AREA WITH CLOUD BASES
AROUND 2500-3500 FEET.

SHOWERS AND THUNDERSTORMS SHOULD DISSIPATE AFTER SUNSET WITH CLOUD
BASES RISING TO 4000 TO 6000 FEET.

MOSTLY CLEAR SKIES EXPECTED TONIGHT WITH LIGHT AND VARIABLE WINDS.
