...SYNOPSIS...
PROGRESSIVE SHORTWAVE PATTERN FCST TO CONTINUE THROUGH DAY-2
PERIOD...AMIDST SLOWLY DEAMPLIFYING LARGE SCALE WAVE TRAIN THAT HAS
FEATURED ERN TROUGH AND WRN RIDGE.  STRONG SHORTWAVE TROUGH -- NOW
EVIDENT IN MOISTURE CHANNEL IMAGERY OVER OK -- WILL ACCELERATE ESEWD
OFF GA/SC COAST DURING PERIOD AMIDST CONFLUENT SYNOPTIC SCALE FLOW
ALOFT. SFC COLD FRONT -- ASSOCIATED BOTH WITH THIS FEATURE AND WITH
NRN STREAM TROUGH CROSSING GREAT LAKES/MID-ATLANTIC REGIONS -- WILL
SWEEP SEWD ACROSS MS VALLEY...APPALACHIANS AND SRN PLAINS.  FRONT
SHOULD REACH NRN FL AND NRN GULF BY END OF PERIOD.

IS EXPECTED TO MOVE INLAND AROUND 27/00Z.

...W COAST AND SW...
ISOLATED TO WIDELY SCATTERED TSTMS POSSIBLE MAINLY DURING AFTERNOON
AND EARLY EVENING.  NRN STREAM SEGMENT OF LANDFALLING UPPER TROUGH
WILL FEATURE TIGHTER HEIGHT GRADIENT AND SOMEWHAT STRONGER MIDLEVEL
DPVA/LIFT...BUT WEAKER LOW LEVEL INSTABILITY AS IT MOVES ACROSS
PACIFIC NW.  MEANWHILE SRN STREAM PORTION CONTRIBUTES TO INLAND
DESTABILIZATION AS FAR E AS SRN BASIN-AND-RANGE REGION.  EXPECT
MIDLEVEL LAPSE RATES TO STEEPEN THROUGHOUT FIRST HALF OF
PERIOD...AND LOW LEVEL LAPSE RATES TO INCREASE ESPECIALLY FROM LOWER
CO VALLEY EWD BECAUSE OF  SFC HEATING. HEATING WILL BE MORE LIMITED
ACROSS MUCH OF CA...BUT WITH STRONGER FORCING ALOFT.  NET RESULT
SHOULD BE 50-300 J/KG MLCAPE IN POCKETS ACROSS MUCH OF GEN THUNDER
AREA.
