...EXTREMELY CRITICAL FIRE WEATHER AREA FOR SERN NM...WRN TX...OK
PANHANDLE INTO FAR NWRN OK AND SWRN KS...
...CRITICAL FIRE WEATHER AREA FOR SRN AND ERN NM...W TX...WRN
OK...WRN KS...ERN CO...SWRN NEB...
...SYNOPSIS...
A BROAD AREA OF SWLY FLOW ALOFT WILL EXIST ACROSS THE CNTRL U.S.
WITH A TROUGH OVER THE FOUR CORNERS AND AN UPPER RIDGE BUILDING OVER
THE ERN CONUS. A SURFACE LOW WILL DEEPEN OVER WRN NEB WITH A LEE
TROUGH EXTENDING SWD INTO W TX BY AFTERNOON. VERY STRONG WINDS...HOT
TEMPERATURES...AND LOW RH WILL RESULT IN CRITICAL FIRE WEATHER
CONDITIONS FROM NM AND TX NWD INTO NEB. TO THE E...VERY WARM WEATHER
WILL ENVELOPE MUCH OF THE MS VALLEY AND MIDWEST WITH A RIDGE ALOFT.
LOW AFTERNOON RH WILL EXIST WITH A SURFACE HIGH OVER THE SE AND
GUSTY WINDS WILL EXIST OVER THE MIDWEST.
...NM/TX/OK/KS/CO/NEB...
STRONG WIND FIELDS WILL CONTINUE TO INCREASE ALOFT AS THE TROUGH
APPROACHES. AT THE SURFACE...A LOW PRESSURE TROUGH WILL DEEPEN FROM
SW NEB INTO W TX. STRONG MIXING AND VERY WARM TEMPERATURES WILL HELP
PRODUCE VERY STRONG AND GUSTY WINDS LATER TODAY. SUSTAINED SWLY
WINDS OF 30-40 MPH ARE EXPECTED ACROSS MOST OF THE CRITICAL
AREA....WITH GUSTS OVER 50 MPH ACROSS THE EXTREME AREA FROM ERN NM
ACROSS W TX AND INTO FAR NWRN OK AND SW KS. MIN RH MAY ONCE AGAIN
REACH THE UPPER SINGLE DIGITS OVER SE NM AND MUCH OF W TX...WITH
LOWER TEENS ELSEWHERE. OVERNIGHT...WINDS WILL SHIFT TO NWLY AT 15-25
MPH AND GUSTY WITH A COLD FRONT. AT LEAST ISOLATED THUNDERSTORMS
WILL HELP RELIEVE THE FIRE THREAT AS WELL...FROM NW TX INTO WRN OK
AND S CNTRL KS.
...NRN MN AND WI...
A STRENGTHENING PRESSURE GRADIENT WILL EXIST TODAY AS THE LOW
DEEPENS TO THE SW. A DRY AIR MASS IS ALREADY IN PLACE...AND EVEN
WITH BACK SURFACE WINDS OUT OF THE E AND NE ACROSS NRN MN...RH IS
STILL LIKELY TO DROP INTO THE 30 PERCENT RANGE WITH TEMPERATURES
RANGING FROM THE 60S NRN MN WELL INTO THE 70S CNTRL MN AND NRN WI.
COMBINED WITH GUSTY WINDS OF 15-20 MPH...THIS MAY YIELD A MARGINAL
FIRE THREAT THIS AFTERNOON.
...SERN STATES...TN/OH VALLEYS...
VERY WARM CONDITIONS WILL OVERSPREAD A LARGE PORTION OF THE MIDWEST
INTO THE SERN U.S. TODAY WITH AN UPPER RIDGE ALOFT. SWLY WINDS AHEAD
OF THE WRN TROUGH WILL HELP WARM TEMPERATURES INTO THE LOWER TO MID
80S FROM THE OH/TN VALLEYS INTO FL. A RELATIVELY DRY AIR MASS WILL
REMAIN IN PLACE WITH MIN RH FROM 20-30 PERCENT ACROSS THE SE TO
30-40 PERCENT INTO THE OH VALLEY. DUE TO LOCALIZED TERRAIN EFFECTS
AND VERTICAL MIXING...LOCALLY LOWER RH VALUES ARE POSSIBLE.
