   FL/SWRN GA...
   
   ...SYNOPSIS...
   AMPLIFIED LARGE-SCALE UPPER-LEVEL PATTERN WILL BE DOMINATED BY A
   TROUGH ACROSS THE WEST WITH A RIDGE OVER THE EAST. AN UPPER-LEVEL
   LOW CENTERED OVER ERN MT WILL LIFT NEWD TOWARDS MANITOBA...WHILE AN
   UPSTREAM SHORT WAVE TROUGH EJECTS EWD FROM THE SRN GREAT BASIN
   ACROSS THE FOUR CORNERS AND ONTO THE CENTRAL PLAINS BY THU MORNING.
   AHEAD OF THIS LATTER FEATURE...LEE CYCLOGENESIS WILL OCCUR ACROSS
   THE SRN HIGH PLAINS THIS AFTERNOON. FARTHER EAST...AN EXPANSIVE AREA
   OF HIGH PRESSURE WILL REMAIN ANCHORED JUST OFF THE NEW ENGLAND
   COAST/CANADIAN MARITIME PROVINCES. A MODERATE SURFACE PRESSURE
   GRADIENT WILL CONTINUE ACROSS THE SOUTHEAST.
   
   ...CRITICAL FIRE WEATHER AREA - FL PANHANDLE THROUGH W-CNTRL FL/SWRN
   GA...
   
   PRIMARY CONDITIONS: MODERATE WINDS / LOW RH / LONG-TERM DROUGHT
   
   A 25 TO 35 MPH ELY LOW-LEVEL JET WILL LEAD TO SUSTAINED SURFACE
   WINDS OF 15 TO 25 MPH ACROSS MUCH OF FL/SRN GA FROM LATE MORNING
   THROUGH THIS AFTERNOON. THE OVERALL THERMODYNAMIC PROFILE SHOULD BE
   SIMILAR TO TUESDAY...WITH ELY TRAJECTORIES LIMITING CRITICALLY LOW
   RH CONDITIONS TO WRN PORTIONS OF FL/SWRN GA. HERE...TEMPERATURES
   SHOULD REACH THE UPPER 80S WITH RH VALUES DROPPING TO 25 TO 35
   PERCENT.
   
   ...E-CNTRL THROUGH SWRN NM/FAR SERN AZ...
   SIMILAR TO TUESDAY...TEMPERATURES WILL WARM INTO THE 80S...WITH
   AFTERNOON RH VALUES OF 10 TO 15 PERCENT. ALTHOUGH WINDS ARE LIGHT
   EARLY THIS MORNING...LOW/MID-LEVEL FLOW WILL INCREASE AGAIN THIS
   AFTERNOON AS A SRN GREAT BASIN SHORT WAVE TROUGH APPROACHES AND A
   SURFACE LOW STRENGTHENS ACROSS NERN NM. SUSTAINED SWLY WINDS WILL
   LIKELY REACH 20 TO 25 MPH TOWARDS EARLY EVENING. RECENT ABOVE-NORMAL
   RAINFALL OVER MOST OF THE AREA AND THE RELATIVELY SHORT
   JUXTAPOSITION OF STRONG WINDS/LOW RH SHOULD MITIGATE THE OVERALL
   CRITICAL THREAT.
   
   ...SRN NV/PORTIONS OF SERN CA...
   LATEST MESONET OBSERVATIONS INDICATE GUSTY NLY WINDS AOA 30 MPH HAVE
   LEAD TO POOR OVERNIGHT RH RECOVERY /AROUND 10 TO 20 PERCENT/
   IMMEDIATELY BEHIND A COLD FRONT ALONG THE I-15 CORRIDOR. MODEL
   GUIDANCE FORECASTS ARE CONSISTENT IN RAPIDLY DIMINISHING WINDS LATER
   THIS MORNING AS DIURNAL HEATING ENSUES AND THE THERMAL GRADIENT
   WEAKENS.

   ...CRITICAL FIRE WEATHER AREA FOR FL PANHANDLE THROUGH W-CNTRL
   FL/FAR SWRN GA...
   
   ...SYNOPSIS...
   A MID-LEVEL SHORT WAVE TROUGH OVER THE CNTRL PLAINS WILL LIFT NEWD
   ACROSS THE UPPER MS RIVER VALLEY INTO NWRN ONTARIO BY EARLY FRI.
   PRIMARY SURFACE LOW WILL ACCOMPANY THIS FEATURE ON A SIMILAR
   TRACK...WHILE ATTENDANT COLD FRONT MOVES EWD TOWARDS THE WRN GREAT
   LAKES AND BECOMES MORE QUASI-STATIONARY FARTHER S ACROSS THE SRN
   PLAINS. AN EXPANSIVE AREA OF SURFACE HIGH PRESSURE OFF THE NEW
   ENGLAND/MID-ATLANTIC COAST WILL SINK SLOWLY SWD THROUGH THE PERIOD.
   AS A RESULT...THE SURFACE PRESSURE GRADIENT ACROSS THE SOUTHEAST
   SHOULD GRADUALLY WEAKEN.
   
   ...CRITICAL FIRE WEATHER AREA - FL PANHANDLE THROUGH W-CNTRL FL/FAR
   SWRN GA...
   
   PRIMARY CONDITIONS: MODERATE WINDS / LOW RH / LONG-TERM DROUGHT
   
   PERSISTENT ELY FLOW SHOULD RESULT IN A SUBTLE WWD SHIFT TO
   CRITICALLY LOW RH CONDITIONS FROM THE DAY 1 PERIOD. AFTERNOON RH
   VALUES OF 25 TO 35 PERCENT WILL REMAIN LIKELY AS TEMPERATURES WARM
   TO THE UPPER 80S. OVERALL WIND SPEEDS OUGHT TO BE SLIGHTLY LESS
   COMPARED TO DAY 1 OWING TO A WEAKER SURFACE PRESSURE GRADIENT.
