..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE NOT FORECAST FRIDAY.
..SYNOPSIS
BROAD MID-LEVEL TROUGHING OVER THE EASTERN US IS FORECAST TO
CONTINUE FRIDAY AS SEVERAL SMALL-SCALE PERTURBATIONS PASS OVER THE
PLAINS AND MIDWEST. AT THE SURFACE, A LOW WILL DEEPEN OVER THE
NORTHERN ROCKIES WHILE A STALLED FRONT WILL REMAIN IN PLACE ALONG
THE GULF COAST. BEHIND THE FRONT, A COLD AND DRY POLAR AIR MASS WILL
LARGELY PRECLUDE THUNDERSTORM DEVELOPMENT OVER MUCH OF THE US. THE
EXCEPTION WILL BE ALONG THE CENTRAL AND NORTHEASTERN GULF COAST
WHERE A FEW THUNDERSTORMS ARE POSSIBLE EARLY.
..SOUTHERN LA TO THE FL PANHANDLE
ALONG THE STALLED FRONT, A WEAK WAVE LOW IS FORECAST TO DEVELOP
ACROSS THE NORTHERN GULF AHEAD OF A LOW-AMPLITUDE SHORTWAVE MOVING
OUT OF THE SOUTHERN PLAINS. CONVERGENCE ALONG THE FRONT AND AHEAD OF
THIS FEATURE COULD ALLOW THE FRONT TO MOVE INLAND A FEW MILES FRIDAY
MORNING. WHILE NOT OVERLY WARM NOR MOIST, MODEST DESTABILIZATION
COULD SUPPORT ISOLATED ELEVATED THUNDERSTORMS INLAND AND CLOSER TO
THE COAST THROUGH MIDDAY. STRONG FLOW ALOFT AND BACKING ALONG THE
FRONT COULD ALLOW FOR A FEW TRANSIENT ROTATING CELLS. THIS APPEARS
MOST LIKELY OVER PARTS OF SOUTHERN LA AND THE FL BIG BEND WHERE
STORMS CLOSER TO THE FRONT COULD POTENTIALITY BE NEAR SURFACE-BASED
FOR A COUPLE HOURS. HOWEVER, GIVEN THE WEAK BUOYANCY AND FEW IF ANY
SURFACE-BASED STORMS INLAND FOR A LONGER DURATION, SEVERE POTENTIAL
REMAINS TOO LOW FOR PROBABILITIES.
