VALID 090100Z - 091200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS...
UPPER TROUGH WILL CONTINUE TO EVOLVE WEST OF THE ROCKIES...WITH
90-120 METER HEIGHT FALLS EXPECTED FROM ORE TOWARD SRN CA/NV AS A
COMPACT SHORTWAVE TROUGH DIGS SWD INTO NRN CA THIS FORECAST PERIOD.
MEANWHILE...A CLOSED LOW EMBEDDED WITHIN AN ERN U.S. RIDGE WILL MOVE
SLOWLY NWD FROM SC TO NC...WHILE HEIGHTS CONTINUE TO RISE OVER NEW
ENGLAND AS A WELL AMPLIFIED TROUGH MOVES THROUGH THE CANADIAN
MARITIMES.
...NORTHWEST STATES...
A FEW LIGHTNING STRIKES CANNOT BE RULED OUT THIS EVENING ACROSS NRN
ORE AS FORCING FOR ASCENT SPREADS SWD ACROSS THIS REGION WITHIN THE
EXIT REGION OF A STRONG NLY 500 MB JET...ATTENDANT TO THE DIGGING
SHORTWAVE TROUGH. OVERALL DIURNAL CONVECTION SHOULD CONTINUE TO
WANE GIVEN THE LOSS OF DAYTIME HEATING...STABILIZING THE BOUNDARY
LAYER. TSTM COVERAGE IS EXPECTED TO BE LESS THAN 10 PERCENT...AND
THUS HAVE DISCONTINUED THE GENERAL TSTM AREA FOR THIS REGION.
...SOUTHEAST STATES...
TRENDS IN REGIONAL RADAR IMAGERY AND LIGHTNING DATA EARLY THIS
EVENING SUGGEST ANY ADDITIONAL TSTM POTENTIAL SHOULD REMAIN OFFSHORE
THE SRN ATLANTIC COAST...AS INSTABILITY WEAKENS INLAND.
