AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
307 PM CDT FRI MAY 20 2011

.SYNOPSIS...CONVECTION IS GETTING A LATE START THIS AFTERNOON WITH
THE CAP HOLDING BETTER THAN EXPECTED. THERE DOES LOOK TO BE EROSION
OF THE SAME CAP OVER EAST TEXAS PER LATEST VISIBLE SATELLITE TRENDS.
THE SHORT WAVE WHICH IS UPSTREAM OVER SOUTH TEXAS HAS YET TO SEE
CONVECTION FIRING OFF HOWEVER IT IS TOO SOON TO BACK OFF ON EXPECTED
SHOWERS AND THUNDERSTORMS TONIGHT CONSIDERING THE INSTABILITY AND UPPER
LEVEL SUPPORT AVAILABLE WITH THE RIGHT REAR QUAD OF THE JET AS
WELL AS DEEPENING MOISTURE ACROSS THE NORTHERN ZONES.

&&

.SHORT TERM...MAINLY EVENING SCATTERED SHOWERS AND THUNDERSTORMS REMAIN
IN THE FORECAST EXCEPT AROUND ACADIANA WHERE RIDGING AND DRIER AIR PERSIST.
WENT HIGHER THAN GUIDANCE FOR THE ALEXANDRIA AREA WHERE THE BEST
MOISTURE AND VORTICITY FROM THE SHORT WAVE SHOULD AID IN
DEVELOPMENT. TEMPERATURES SHOULD CONTINUE TRENDING WELL ABOVE
NORMAL TONIGHT THANKS TO A LONG FETCH OF STRONG SOUTHEASTERLY
WINDS OUT OF THE BAY OF CAMPECHE WHERE WATER TEMPS ARE ALREADY
AROUND 80. THE HOTTEST TEMPS OF THE YEAR SO FAR FOR THE ALEXANDRIA
AREA ON SATURDAY DUE TO STRONG SUBSIDENCE FROM RIDGING WITH
SOUTHWESTERLY FLOW ALOFT AFTER THE SHORT WAVE PASSES.

&&

.LONG TERM...THE FAVORABLE UPPER LEVEL WINDS CONTINUE ON SATURDAY
WITH THE RIGHT REAR QUAD OF THE JET. THERE SHOULD BE SUFFICIENT MOISTURE
IN PLACE WITH MODERATE INSTABILITIES FOR SCATTERED SHOWERS AND
THUNDERSTORMS. AGAIN THE ACADIANA AREA LOOKS TO MISS OUT ON MOST
OF THE PRECIP DUE TO THE EFFECTS OF THE RIDGING TO THE EAST.

THIS RIDGE WILL BUILD BACK TO THE WEST AND DOMINATE SUNDAY INTO
EARLY NEXT WEEK. A BROAD UPPER LEVEL TROF WILL BRING A STALLING
FRONTAL SYSTEM INTO OUR REGION WEDNESDAY AND THURSDAY WITH SOME
LOW END CHANCES FOR RAINFALL.
