VALID 261200Z - 271200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE NOT FORECAST ON WEDNESDAY OR WEDNESDAY NIGHT.
..SYNOPSIS
AN AMPLIFIED SHORTWAVE TROUGH WILL FURTHER DEEPEN AS IT SWINGS
ACROSS THE GREAT LAKES INTO THE SAINT LAWRENCE VALLEY. ASSOCIATED
DEEP SURFACE CYCLONE WILL TRACK ACROSS THE CENTRAL GREAT LAKES TO
THE OTTAWA VALLEY. DOWNSTREAM FRONTAL OCCLUSION SHOULD ARC TO A
WEAKER LOW MOVING ACROSS NEW ENGLAND, WITH THE LEADING COLD FRONT
TRAILING SOUTHWARD AND EXITING MUCH OF THE ATLANTIC SEABOARD BY
WEDNESDAY NIGHT.
..EAST
SURFACE-BASED THUNDERSTORM COVERAGE ALONG/AHEAD OF THE
AFOREMENTIONED FRONT IS EXPECTED TO REMAIN SPARSE ON WEDNESDAY,
LIMITING UNCONDITIONAL SEVERE PROBABILITIES. INSTABILITY SHOULD BE
WEAK NORTH OF SOUTH GA/NORTH FL, WHERE STRONG DEEP-LAYER SHEAR WILL
BE PREVALENT AHEAD OF THE AFOREMENTIONED FRONT.
RATHER LOW-TOPPED CONVECTION MAY PRECEDE THE MOST PRONOUNCED
MID-LEVEL DCVA IN THE WESTERN/UPSTATE NY VICINITY ON WEDNESDAY
AFTERNOON. WHILE IT MAY BE INSUFFICIENT TO PRODUCE LIGHTNING AMID
FLIMSY BUOYANCY, IT COULD BE ACCOMPANIED BY STRONG GUSTS ALONG A
SECONDARY SURFACE FRONTAL SURGE WITH A STRENGTHENING PRESSURE
GRADIENT IN ITS WAKE.
