SHORTWAVE TROUGH CURRENTLY LOCATED OVER THE SRN HIGH PLAINS WILL
CONTINUE ESE THROUGH THE GULF OF MEXICO AND WILL BEGIN TO AFFECT THE
FL PENINSULA WEDNESDAY AFTERNOON AND EVENING. THIS FEATURE WILL
DEAMPLIFY AS IT BECOMES ABSORBED WITHIN BASE OF DEEPENING SYNOPTIC
SCALE TROUGH OVER THE ERN STATES.

QUASI-STATIONARY FRONT OVER THE SRN TIP OF FL MAY LIFT NWD SLIGHTLY
AHEAD OF THE SRN STREAM WAVE...BEFORE ACCELERATING OFFSHORE

...DISCUSSION...
MEDIUM RANGE MODELS ARE CONSISTENT SHOWING A FAIRLY PROGRESSIVE AND
AMPLIFIED SRN STREAM PATTERN ACROSS WRN/SWRN U.S. TO THE GULF
COAST/SERN STATES THROUGH THE EARLY TO MIDDLE PART OF NEXT WEEK. 
HOWEVER...GFS/ECMWF DIFFER IN THE TRACK AND AMPLIFICATION OF TWO
SEPARATE PACIFIC TROUGHS EXPECTED TO AFFECT THE SRN TIER OF THE
COUNTRY DURING THE EXTENT OF THE EXTENDED FORECAST PERIOD.

MOISTURE RETURN/MODIFICATION IS EXPECTED TO REMAIN LIMITED WITH THE
INITIAL TROUGH AFFECTING THE GULF COAST STATES DURING DAYS 4-5 /FRI
FEB 26-SAT FEB 27/.  MODELS SUGGEST BETTER MOISTURE RETURN MAY OCCUR

A DEEPENING CLOSED UPPER LOW WILL BE POSITIONED OVER THE
MID-ATLANTIC REGION ON THU/D3...WITH CRITICAL FIRE WEATHER
CONDITIONS LIKELY OVER NRN/CNTRL FL AND EXTREME SE GA. RAPIDLY
DEEPENING SFC CYCLONE OFF THE ATLANTIC COAST...COMBINED WITH SFC
HIGH PRESSURE OVER THE UPPER MS VALLEY...WILL REINFORCE DRY
CONTINENTAL NWLY WINDS. ALTHOUGH AFTERNOON SFC TEMPERATURES WILL BE
RELATIVELY COOL /IN THE 40S AND 50S/...RH VALUES WITHIN THE VERY DRY
AIR MASS ARE STILL EXPECTED TO FALL INTO THE 20S TO LOWER 30S. IN
ADDITION...SUSTAINED WIND SPEEDS OF 15-20 MPH ACROSS NRN FL...TO
20-30 MPH IN SE GA...WILL COMBINE WITH THE DRY AIR TO PRODUCE
CRITICAL FIRE WEATHER CONDITIONS.

WATER VAPOR IMAGERY CURRENTLY SHOWS A PRONOUNCED UPPER-LEVEL TROUGH
OVER THE UPPER MS VALLEY WITH AN EXTENSION OF THE TROUGH SWWD INTO
THE SRN ROCKIES. THE TWO UPPER-LEVEL SYSTEMS WILL CONSOLIDATE INTO
ONE UPPER-LEVEL TROUGH OVER THE MS VALLEY TONIGHT. AT THE SFC...HIGH
PRESSURE WILL BE REINFORCED IN THE GREAT PLAINS WITH NLY FLOW IN
PLACE ACROSS MUCH OF THE CNTRL AND ERN STATES. THIS WILL KEEP THE
HIGHER SFC-DEWPOINTS WELL OFFSHORE IN THE CNTRL AND SRN GULF OF
MEXICO. FOR THIS REASON...THUNDERSTORM ACTIVITY IS NOT EXPECTED
ACROSS THE CONUS TODAY OR TONIGHT.

THE LATEST WATER VAPOR IMAGERY SHOWS TWO SUBTLE SHORTWAVE TROUGH
FEATURES MOVING EWD ACROSS THE ERN GULF COAST STATES. THE FIRST
SHORTWAVE TROUGH IS CURRENTLY LOCATED IN CNTRL FL WHERE A CLUSTER OF
THUNDERSTORMS IS ONGOING IN THE VICINITY OF ORLANDO. THE SECOND
SHORTWAVE TROUGH IS LOCATED ACROSS SRN AL AND THE FL PANHANDLE WHERE
ISOLATED THUNDERSTORMS ARE ALSO PRESENT. OBJECTIVE ANALYSIS IN BOTH
THESE AREAS SUGGESTS INSTABILITY IS VERY WEAK WITH MUCAPE VALUES
BELOW 250 J/KG. THIS COMBINED WITH COOLING SFC TEMPS THIS EVENING
