..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS APPEAR UNLIKELY FRIDAY THROUGH FRIDAY NIGHT.
..SYNOPSIS
LARGE-SCALE RIDGING WILL GENERALLY BE MAINTAINED ACROSS THE WESTERN
US AS A BROAD, MULTI-COMPONENT UPPER TROUGH OVER THE EASTERN HALF OF
THE US IS FORECAST TO RAPIDLY CONSOLIDATE AND STRENGTHEN FRIDAY INTO
EARLY SATURDAY. A PROMINENT SHORTWAVE IMPULSE EMANATING FROM
SOUTHERN CANADA WILL MERGE WITH SEVERAL SMALLER PERTURBATIONS OVER
THE SOUTHERN MS VALLEY AND GULF COAST VICINITY. THE NET RESULT WILL
BE A LARGE AND INTENSE POSITIVE TILT UPPER TROUGH OVER THE
SOUTHEASTERN CONUS. THIS STRONG TROUGH AND 100+ KT MID-LEVEL FLOW
WILL AIDE THE DEVELOPMENT OF AN INITIALLY WEAK SURFACE CYCLONE OVER
THE EASTERN GULF AND FL PENINSULA. THE LOW WILL RAPIDLY DEEPEN LATE
FRIDAY INTO EARLY SATURDAY OFF THE ATLANTIC COAST AS A COLD FRONT
MOVES OFFSHORE. AHEAD OF THE FRONT, MODEST LOW-LEVEL
MOISTENING/DESTABILIZATION IS POSSIBLE OVER PARTS OF SOUTHERN FL AND
THE KEYS. HOWEVER, THIS APPEARS SHORT LIVED AND WITHOUT MORE
SUBSTANTIAL ASCENT/DESTABILIZATION, THUNDERSTORMS ARE UNLIKELY.
