VALID 141200Z - 151200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THERE APPEARS TO BE LITTLE SUBSTANTIVE CHANGE TO MODEL FORECASTS FOR
THIS FORECAST PERIOD. AMPLIFIED EASTERN PACIFIC/WESTERN NORTH
AMERICAN UPPER RIDGING AND CENTRAL/EASTERN NORTH AMERICAN UPPER
TROUGHING IS EXPECTED TO PERSIST TUESDAY. IT STILL SEEMS LIKELY
THAT THERE WILL BE SUBSTANTIAL DEEPENING OF THE TROUGH...BETWEEN THE
MISSISSIPPI VALLEY AND THE APPALACHIANS...IN RESPONSE TO THE
CONTINUED DIGGING OF A VIGOROUS SHORT WAVE IMPULSE ASSOCIATED WITH A
REINFORCING COLD INTRUSION IN LOWER LEVELS. IN ADVANCE OF THIS
FEATURE...A SIGNIFICANT SHORT WAVE IMPULSE WILL PROBABLY ACCELERATE
OUT OF THE BASE OF THE LARGER SCALE UPPER TROUGHING...NEAR THE
CENTRAL/EASTERN GULF COAST...THROUGH NEW ENGLAND BY 12Z WEDNESDAY.
ASSOCIATED MODEST SURFACE FRONTAL WAVE DEVELOPMENT IS EXPECTED TO
MIGRATE OFF SOUTHERN MID ATLANTIC COASTAL AREAS BY MID DAY
TUESDAY...BEFORE CONTINUING RAPIDLY NORTH NORTHEASTWARD THROUGH THE
REMAINDER OF THE PERIOD...NEAR OR JUST EAST OF THE ATLANTIC
SEABOARD. WHILE THERE MAY BE LINGERING THUNDERSTORM ACTIVITY NEAR
THE FRONTAL WAVE AND FRONT ACROSS MID ATLANTIC COASTAL AREAS AND
PARTS OF THE FLORIDA PENINSULA...PARTICULARLY EARLY IN THE
DAY...MINIMAL BOUNDARY LAYER BASED CAPE AND WEAK LOWER/MID
TROPOSPHERIC LAPSE RATES SEEM LIKELY TO PRECLUDE AN APPRECIABLE
SEVERE WEATHER THREAT. ELSEWHERE...DRY OR OTHERWISE STABLE
CONDITIONS ARE EXPECTED TO MAINTAIN NEGLIGIBLE CONVECTIVE POTENTIAL
ACROSS THE REMAINDER OF THE NATION.
