...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
FAST W TO WNW FLOW WILL PERSIST OVER THE NORTHEAST THROUGH TUE...
WHILE MODERATE...LOW AMPLITUDE...MULTI-STREAM FLOW PREVAILS
ELSEWHERE. A SERIES OF FAIRLY WEAK SRN STREAM TROUGHS WILL PROGRESS
SLOWLY ENE ACROSS THE NRN GULF OF MEXICO/GULF CST
STATES...DOWNSTREAM FROM LARGER SCALE CYCLONIC CIRCULATION OVER THE
E PACIFIC.
...FL PENINSULA...
COLD FRONT THAT STALLED S OF THE FL KEYS YESTERDAY WILL TEMPORARILY
REDEVELOP N ACROSS THE PENINSULA TODAY AS AN INVERTED TROUGH FORMS
OVER THE NERN GULF AHEAD OF AFOREMENTIONED UPR TROUGH. LATE IN THE
PERIOD /AFTER 06Z TUE/...INCREASING UVV BENEATH SE FRINGE OF THE UPR
TROUGH SHOULD SUPPORT DEVELOPMENT OF A WEAK SFC LOW OFF THE NE FL
CST. THESE CHANGES WILL BE ACCOMPANIED BY AN INCREASING CHANCE FOR
TSTMS TODAY OVER THE SRN THIRD OF THE PENINSULA...AND TONIGHT/TUE
MORNING NWD ALONG THE FL E CST.
WHILE THE LWR LVLS WILL GRADUALLY MOISTEN /PW AOA 1.75 IN WARM
SECTOR/...LOW AMPLITUDE OF UPR PATTERN AND EXISTING MID LVL
TEMPERATURES SUGGEST THAT MID LVL LAPSE RATES WILL REMAIN WEAK.
THIS WILL LIMIT DEGREE OF DESTABILIZATION. IN ADDITION...WHILE SOME
DEGREE OF LOW LVL DIRECTIONAL SHEAR WILL EXIST...ESPECIALLY IN WAA
ZONE ALONG THE E CST...LOW TO MID LVL WINDS WILL BE RELATIVELY WEAK.
THESE FACTORS SHOULD PRECLUDE ANY APPRECIABLE SVR THREAT.

MOIST AXIS/ EXTENDS NNE INTO LA FROM THE NWRN GULF. WDLY SCTD
THUNDER MAY PERSIST/INCREASE WITHIN THIS AXIS UNTIL BAND OF ASCENT
WITH UPR TROUGH MOVES BEYOND REGION LATER TODAY.
