..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
ISOLATED THUNDERSTORMS ARE POSSIBLE ALONG THE GULF COAST ON

..SYNOPSIS
DIFFUSE MID-LEVEL TROUGHING OVER THE EASTERN US IS AGAIN EXPECTED
SATURDAY AS A SECONDARY SHORTWAVE TROUGH MOVES OUT OF THE ROCKIES
AND OVER THE PLAINS. AHEAD OF THE WESTERN TROUGH, A LEE LOW WILL
DEEPEN OVER PARTS OF THE CENTRAL PLAINS, NORTH OF A STALLED FRONT
ALONG THE GULF COAST. HIGH PRESSURE OVER THE SOUTHEASTERN US WILL
WEAKEN AS A COOL POLAR AIR MASS SLOWLY MODIFIES.
AS THE SURFACE LOW MOVES SOUTH TOWARD THE GULF COAST LATE SATURDAY,
WEAK INLAND MOISTURE ADVECTION IS EXPECTED OVER PARTS OF COASTAL
SOUTHEAST TX AND SOUTHERN LA INTO EARLY SUNDAY. ISOLATED
THUNDERSTORMS ARE POSSIBLE GIVEN THE ASCENT AND WEAK BUOYANCY THAT

OFFSHORE. THUS, WHILE SOME ELEVATED STORMS ARE POSSIBLE INLAND, THE
SEVERE RISK APPEARS LOW.
