..DISCUSSION
..THURSDAY/DAY 4 AND FRIDAY/DAY 5
A MID-LEVEL LOW IS FORECAST TO MOVE INTO THE SOUTHERN HIGH PLAINS ON
THURSDAY/DAY 4, AS AN ASSOCIATED JET STREAK MOVES ACROSS TEXAS.
WIDESPREAD CONVECTION APPEARS LIKELY TO BE ONGOING AT THE START OF
THE PERIOD, RELATED TO AN MCS ALONG THE WESTERN EDGE OF THE MOIST
SECTOR. IT APPEARS THE MCS WILL MOVE INTO CENTRAL AND NORTHEAST
TEXAS DURING THE AFTERNOON, WHERE SURFACE DEWPOINTS SHOULD BE IN THE
60S F. THIS MOIST AND UNSTABLE AIRMASS WILL MAKE STRONG TO SEVERE
THUNDERSTORMS BE POSSIBLE IN THE AFTERNOON AS THE MID-LEVEL JET
EJECTS NORTHEASTWARD ACROSS THE REGION. SUPERCELLS WITH ISOLATED
LARGE HAIL AND SEVERE GUSTS WILL BE POSSIBLE.
THE MID-LEVEL SYSTEM IS FORECAST TO MOVE ACROSS THE ARK-LA-TEX ON
FRIDAY/DAY 5, AS A COLD FRONT ADVANCES EASTWARD INTO THE CENTRAL
GULF COAST STATES. THUNDERSTORMS WILL BE POSSIBLE ALONG AND AHEAD OF
THE FRONT DURING THE DAY, AND A MARGINAL SEVERE THREAT MAY DEVELOP
NEAR THE CENTRAL GULF COAST.
..SATURDAY/DAY 6 TO MONDAY/DAY 8
THE COLD FRONT IS FORECAST TO MOVE QUICKLY EASTWARD INTO THE
ATLANTIC BY SATURDAY AS SURFACE HIGH PRESSURE SETTLES OVER THE
EASTERN U.S. A WEST-NORTHWEST FLOW MID-LEVEL PATTERN IS FORECAST IN
THE CENTRAL AND EASTERN U.S. ON SUNDAY/DAY 7 AND MONDAY/DAY 8. THIS
COULD HELP TO LIMIT MOISTURE RETURN, KEEPING THE CHANCE FOR
THUNDERSTORMS LOW ACROSS THE CONTINENTAL U.S.
