...EXTREMELY CRITICAL FIRE WEATHER AREA FOR NERN AZ/SERN UT/SWRN
CO/FAR NWRN NM...
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SRN AND ERN UT/NRN
AZ/NRN NM/WRN CO...
...SYNOPSIS...
AN UNSEASONABLY STRONG UPPER TROUGH CENTERED ROUGHLY OVER SERN ORE
AS OF 06Z WILL SLOWLY MOVE ENEWD TOWARDS THE NRN ROCKIES BY
AFTERNOON. IN RESPONSE...SURFACE LOW PRESSURE IN SERN MT WILL
GRADUALLY SHIFT EWD AND DEEPEN OVER WRN SD BY AFTERNOON. A COLD
FRONT WILL EXTEND SWWD FROM THE SURFACE LOW THROUGH CNTRL
WY/UT...THEN WWD AND BECOMING STALLED ACROSS SWRN UT AND NV. STRONG
SWLY LOW/MID LEVEL WINDS WILL OVERSPREAD A WARM/DRY AIRMASS AHEAD OF
THE FRONT...LEADING TO EXTREMELY CRITICAL CONDITIONS ACROSS PORTIONS
OF AZ/UT/CO/NM.
MEANWHILE...LEE TROUGHING WILL BEGIN TO DEVELOP IN ASSOCIATION WITH
THE UPPER SYSTEM...WITH STRENGTHENING SLY WINDS RESULTING ACROSS THE
GREAT PLAINS. THIS WILL LEAD TO AN ENHANCED FIRE THREAT OVER
PORTIONS OF THE SRN PLAINS.
...EXTREMELY CRITICAL FIRE WEATHER AREA - NERN AZ/SERN UT/SWRN
CO/FAR NWRN NM...
PRIMARY CONDITIONS: HOT TEMPERATURES/LOW RH/VERY STRONG AND GUSTY
WINDS
AS THE UNSEASONABLY STRONG UPPER LOW SLOWLY PROGRESSES ENEWD...A DRY
SLOT SEEN ON WV IMAGERY FROM SRN CA NEWD INTO SRN UT WILL SLOWLY
DRIFT EWD AS WELL. HEATING/DRY AIR AND SUBSEQUENT MIXING WILL BE
MAXIMIZED IN A CORRIDOR GENERALLY EXTENDING FROM NERN AZ INTO
W/CNTRL WY. CURRENT VAD WIND PROFILE DATA ACROSS THIS AREA INDICATES
ABOUT 40 MPH OF WIND JUST OFF THE SURFACE. GIVEN THE STRENGTH OF THE
SYSTEM AND ASSOCIATED LOW LEVEL WINDS...LITTLE DECREASE IN SPEEDS
CAN BE ANTICIPATED. AS TEMPERATURES WARM AND MIXING BEGINS TO
OCCUR...GUSTS WILL LIKELY BEGIN TO INCREASE TO NEAR 30 MPH BY LATE
MORNING. FURTHER HEATING/MIXING WILL SUPPORT SUSTAINED WIND SPEEDS
NEAR 15 TO 25 MPH WITH GUSTS TO 45 MPH BY AFTERNOON. RHS IN THE
UPPER SINGLE DIGITS AND TO MID TEENS CAN BE EXPECTED.
...CRITICAL FIRE WEATHER AREA - PORTIONS OF SRN AND ERN UT/NRN
AZ/NRN NM/WRN CO...
PRIMARY CONDITIONS: HOT TEMPERATURES/LOW RH/STRONG WINDS
SURROUNDING THE EXTREMELY CRITICAL...HOT/DRY CONDITIONS WILL
DOMINATE...WITH RHS WIDELY IN THE UPPER SINGLE DIGITS AND TEENS.
ALTHOUGH THE AREA OF STRONGEST WINDS WILL GENERALLY BE CONFINED TO
THE EXTREMELY CRITICAL AREA...SUSTAINED SPEEDS NEAR 20 MPH WITH
GUSTS TO 35 MPH WILL STILL BE POSSIBLE. GIVEN ANTECEDENT DRYNESS...A
HEIGHTENED FIRE THREAT WILL EXIST.
...SRN KS/NRN OK/TX PANHANDLE/SERN CO/NERN NM...
IN RESPONSE TO THE APPROACHING UPPER SYSTEM...A LEE TROUGH WILL
BEGIN TO DEVELOP...AND STRENGTHENING SLY WINDS ACROSS THE GREAT
PLAINS WILL ENSUE. SUSTAINED SPEEDS NEAR 20 TO 30 MPH WITH
OCCASIONAL GUSTS WILL DEVELOP BY AFTERNOON. HOT TEMPERATURES CAN BE
ANTICIPATED ONCE AGAIN...WITH HIGHS REACHING INTO THE MID 90S TO
NEAR 102 F AND RESULTING RHS IN THE MID TEENS TO UPPER 20S. DESPITE
OVERALL FAVORABLE CONDITIONS...RECENT RAINFALL MAY TEMPER THE
OVERALL THREAT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0328 AM CDT FRI AUG 07 2009
VALID 081200Z - 091200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
AN UNSEASONABLY STRONG UPPER TROUGH WILL CONTINUE TO SLOWLY PROGRESS
EWD THROUGH D2...BECOMING CENTERED OVER THE NRN HIGH PLAINS AND
EXTENDING SWWD TOWARDS SRN CA BY LATE AFTERNOON. MEANWHILE AT THE
SURFACE...AN ASSOCIATED LOW WILL PROGRESS EWD AND BECOME CENTERED
NEAR THE SD/MN BORDERS. A NEARLY STATIONARY FRONT WILL EXTEND SWWD
FROM THIS TO A SECOND LOW OVER SERN CO. SLY WINDS WILL INCREASE IN
RESPONSE TO THE UPPER SYSTEM AND AS THE SURFACE PRESSURE INCREASES
BETWEEN THE AFOREMENTIONED LOW PRESSURE AND A HIGH TO THE E.
STRONG/GUSTY WINDS WILL ALIGN WITH MARGINALLY LOW RHS TO SUPPORT AN
ENHANCED FIRE THREAT OVER PORTIONS OF THE SRN PLAINS.
...NERN NM/TX AND OK PANHANDLES/SWRN KS/SERN CO...
AS THE UPPER LOW CONTINUES TO PROGRESS EWD...DRIER MID/UPPER LEVEL
AIR SEEN ON WV IMAGERY OVER THE FOUR CORNERS REGION WILL PROGRESS
EWD AS WELL...BECOMING ORIENTED OVER PORTIONS OF THE SRN PLAINS FOR
D2. TEMPERATURES AT THE SURFACE WILL QUICKLY WARM...REACHING INTO
THE UPPER 90S TO NEAR 101 F BY MID/LATE AFTERNOON...THOUGH RHS WILL
BE MARGINAL...ONLY MIXING INTO THE LOWER 20S. WINDS WILL STRENGTHEN
IN RESPONSE TO THE SYSTEM...BECOMING SUSTAINED NEAR 20 TO 25 MPH
WITH GUSTS TO 35 MPH. MARGINAL RHS AND RECENT RAINFALL WILL PRECLUDE
A CRITICAL OUTLINE AT THIS TIME...DESPITE OTHERWISE FAVORABLE
CONDITIONS.
