LARGE HAIL WILL BE POSSIBLE WITH THE STRONGER THUNDERSTORMS THROUGH
TONIGHT. TO THE WEST THE MAIN UPPER TROF OVER THE CENTRAL PLAINS
STATES CONTINUES TO SHIFT SLOWLY EASTWARD WITH A STRONG COLD FRONT
PUSHING OFF THE TX COAST THIS AFTERNOON PROGGED TO MOVE THROUGH
FORECAST AREA EARLY WED. WELL TO THE SOUTH LATEST IR/WV LOOPS SHOW A
STRONG SHORTWAVE MOVING NORTHEAST OVER THE WEST CENTRAL
GULF...TOWARDS THE CENTRAL GULF STATES...LIKELY LEADING TO INCREASED
MID FORCING FROM THE SOUTH EARLY THIS EVENING COMBINED WITH A 50 TO
60 KT H85 JET MOVING IN FROM THE WEST. THE RIGHT REAR QUAD OF AN 150
KNOT UPPER JET IS ALSO NOTED OVER TEXAS PROGGED TO SHIFT EASTWARD TO

BE EXTENDED EASTWARD THROUGH THE OVERNIGHT AND EARLY MORNING HOURS.
LATEST MODEL SOUNDINGS SHOW A STRONG CAP AROUND 14 KFT BREAKING DOWN

LINGERING INTO THE AFTERNOON HOURS WILL CONTINUE TO ERODE OVER MOST
INLAND AREAS THROUGH THIS EVENING THOUGH MAY REDEVELOP ALONG THE
IMMEDIATE COAST DUE TO THE FOG CONTINUING OVER THE COOLER NEAR SHORE
WATERS THROUGH MUCH OF THE NIGHT.

AS FOR TEMPS WILL USE A BLEND OF THE WARMER MOS NUMBERS THROUGH WED

LIGHT SHOWERS WITH IT. A COLDER AND DRIER AIRMASS MOVES INTO THE AREA
IN THE WAKE OF THE FRONT THROUGH FRIDAY NIGHT AS HIGH PRESSURE
BUILDS ACROSS THE AREA. TEMPERATURES WILL DROP BACK TO BELOW NORMAL
LEVELS. /13

LONG TERM /SATURDAY THROUGH TUESDAY/...A STRONG SHORTWAVE WILL DIG
ACROSS THE SOUTHERN STATES ON SATURDAY. HOWEVER...THE GLOBAL MODELS
NOW DIG THE SYSTEM MUCH FARTHER SOUTH INTO THE NORTHERN GULF...WHICH
KEEPS MUCH OF THE PRECIP TO OUR SOUTH AND EAST. DUE TO THE BETTER
AGREEMENT...HAVE LOWERED RAIN CHANCES THROUGH THE WEEKEND TO SLIGHT
CHANCE. EARLY NEXT WEEK LOOKS TO TURN MUCH COLDER AS A HIGHLY
AMPLIFIED TROUGH DIGS ACROSS THE EASTERN STATES.

MARINE...AREAS OF DENSE FOG WILL CONTINUE OVER THE NEAR SHORE
WATERS OF ALABAMA AND NORTHWEST FLORIDA THROUGH THIS EVENING...THEN
ERODE SLOWLY THROUGH WEDNESDAY MORNING. SHOWERS AND THUNDERSTORMS
