NWS STORM PREDICTION CENTER NORMAN OK
0325 AM CDT FRI MAR 21 2008
VALID 211200Z - 221200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
A LOW AMPLITUDE UPPER SHORTWAVE TROUGH AS WELL AS A SURFACE LOW WILL
MOVE EWD FROM NRN MO INTO IL/IN BY AFTERNOON...WITH A WEAK COLD
FRONT EXTENDING FROM SERN MO TO NRN TX. BEHIND THIS FRONT...IT WILL
REMAIN QUITE DRY ALONG WITH LOCALLY GUSTY NLY WINDS...BUT SPEEDS
SHOULD REMAIN SUB-CRITICAL OVER THE SRN PLAINS.
TO THE E...HIGH PRESSURE CENTER WILL MOVE OFF THE SE COAST BUT WILL
MAINTAIN DRY SLY WINDS OVER THE REGION. NEAR CRITICAL CONDITIONS
WILL RESULT OVER NC AND VA...WHERE DROUGHT PERSISTS AND RH WILL BE
VERY LOW.
ELSEWHERE..HIGH PRESSURE WILL GRADUALLY SPREAD SWD ACROSS THE GREAT
BASIN INTO THE SWRN STATES AS AN UPPER TROUGH AMPLIFIES OVER THE
ROCKIES LATE IN THE PERIOD...RESULTING IN OFFSHORE WINDS FOR SRN CA.
...MID ATLANTIC REGION...
A VERY DRY AIR MASS WILL BE IN PLACE TODAY DUE TO HIGH PRESSURE.
HIGH TEMPERATURES SHOULD REACH THE 60S OVER VA TO THE LOWER 70S OVER
ERN NC...RESULTING IN MIN RH VALUES AS LOW AS THE TEENS. SWLY WINDS
NEAR 10 MPH WITH HIGHER GUSTS WILL RESULT IN A MARGINAL FIRE THREAT
TODAY.
...CNTRL AND SRN HIGH PLAINS...
A VERY DRY AIR MASS WILL REMAIN IN PLACE AFTER PASSAGE OF A WEAK
COLD FRONT. TEMPERATURES WILL ONLY BE SLIGHTLY COOLER...WITH HIGHS
IN THE LOW TO MID 70S. MIN RH WILL BE MAINLY IN THE TEENS.
SUSTAINED NLY WINDS NEAR 15 MPH...WITH HIGHER GUSTS WILL RESULT IN
AN ELEVATED BUT OVERALL SUB-CRITICAL FIRE THREAT TODAY.
...LOWER MS VALLEY INTO THE SERN STATES...
A VERY DRY AIR MASS WILL REMAIN IN PLACE TODAY AS A RESULT OF
MODIFYING HIGH PRESSURE. MIN RH VALUES WILL EASILY DIP INTO THE 20
PERCENT RANGE OVER ALL OF THE GULF COAST STATES WITH THE EXCEPTION
OF CNTRL AND SRN FL. WINDS WILL SHIFT FROM ELY TO SLY...GENERALLY AT
OR BELOW 10 MPH...AS A LOW PRESSURE TROUGH MOVES ACROSS THE MID
MS/OH VALLEYS. GIVEN SEVERAL HOURS OF LOW RH...A NEAR CRITICAL FIRE
THREAT WILL EXIST...WITH THE MITIGATING FACTORS BEING MARGINAL WINDS
AND RECENT PRECIPITATION. THE GREATEST FIRE THREAT WILL BE OVER SRN
GA AND NRN FL...WHERE IT HAS BEEN DRIER OVER THE PAST WEEK.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0326 AM CDT FRI MAR 21 2008
VALID 221200Z - 231200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
A WEAK SURFACE LOW WILL SHIFT SEWD ACROSS THE MID ATLANTIC REGION
WITH A COLD FRONT TRAILING SWWD ACROSS THE SRN APPALACHIANS INTO NRN
AL BY SAT AFTERNOON. IT WILL BECOME MODERATELY WINDY AHEAD OF THIS
FRONT WITH A MARGINALLY CRITICAL FIRE THREAT FOR THE CAROLINAS WHERE
POCKETS OF LOW RH WILL REMAIN. TO THE W...HIGH PRESSURE WILL
STRETCH FROM THE NRN ROCKIES EWD ACROSS THE PLAINS INTO THE
MIDWEST...AND WILL SURGE SWD THROUGH THE CNTRL AND SRN PLAINS
OVERNIGHT AS A CLIPPER SYSTEM HELPS TO AMPLIFY THE UPPER TROUGH
ACROSS THE NRN PLAINS. TO THE W...AN UPPER RIDGE WILL BUILD ACROSS
THE GREAT BASIN WITH SURFACE HIGH PRESSURE IN PLACE...RESULTING IN
DRY OFFSHORE FLOW NEAR THE COASTAL RANGE IN SRN CA.
...GA/SC/NC/SERN VA...
NEAR CRITICAL CONDITIONS MAY DEVELOP SAT AFTERNOON AHEAD OF A COLD
FRONT...WHERE SWLY WINDS NEAR 15 MPH WILL OCCUR WITH HIGHER GUSTS.
THE AIR MASS IS EXPECTED TO MODIFY SOMEWHAT...RAISING RH LEVELS BUT
POCKETS OF RH IN THE 20 PERCENT RANGE ARE LIKELY. THE POTENTIAL
EXISTS FOR AN UPGRADE TO CRITICAL IN NEXT DAY ONE SHOULD WINDS
BECOME STRONGER THAN ANTICIPATED ALONG WITH MORE WIDESPREAD LOW RH.
...CNTRL AND SRN HIGH PLAINS...
NELY WINDS NEAR 15 MPH WITH HIGHER GUSTS WILL OCCUR ACROSS THE SRN
PLAINS IN RESPONSE TO HIGH PRESSURE TO THE N AND A WEAK DIURNAL LOW
PRESSURE TROUGH OVER SRN NM/SWRN TX. COOLER TEMPERATURES IN THE 50S
KS/N TX INTO THE 60S WRN/CNTRL TX WILL YIELD MARGINAL RH VALUES IN
THE 20 AND 30 PERCENT RANGE.
