DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0315 AM CDT WED JUN 11 2008
VALID 111200Z - 121200Z
...EXTREMELY CRITICAL FIRE WEATHER AREA FOR NERN NM/FAR WRN OK AND
TX PANHANDLES...
...CRITICAL FIRE WEATHER AREA FOR ERN AZ/MUCH OF NM/SRN CO/SWRN
KS/MUCH OF THE OK AND TX PANHANDLES...
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SACRAMENTO
VALLEY/COASTAL RANGES OF NRN CA...
...SYNOPSIS...
DEEP UPPER-LEVEL LOW OVER THE NRN ROCKIES WILL TRANSLATE SLOWLY EWD
ACROSS THE NRN HIGH PLAINS. MID-LEVEL JET /WITH SPEEDS AOA 60 MPH AT
500 MB/ WILL BECOME CENTERED FROM THE SIERRA NEVADA MTNS THROUGH THE
FOUR CORNERS NEWD ACROSS THE NRN/CNTRL PLAINS BY THIS AFTERNOON. LEE
CYCLONE WILL DEVELOP INTO SERN CO/SWRN KS BY 12/00Z...WITH ATTENDANT
DRYLINE DRAPED SWD THROUGH WRN TX.
...EXTREMELY CRITICAL FIRE WEATHER AREA - NERN NM/FAR WRN OK AND TX
PANHANDLES...
PRIMARY CONDITIONS: VERY STRONG WINDS / LOW RH / DROUGHT
ON THE SRN PERIPHERY OF AN INTENSE MID-LEVEL JET STREAK EJECTING
FROM THE FOUR CORNERS TO THE CNTRL PLAINS...VERY STRONG SWLY WINDS
WILL DEVELOP THIS AFTERNOON DOWNWIND OF THE SACRAMENTO MTNS. THIS
WILL ENHANCE DOWNSLOPE EFFECTS WITH DEEPLY-MIXED THERMODYNAMIC
PROFILES. SUSTAINED SURFACE WINDS WILL LIKELY REACH 35 MPH. RH
VALUES WILL PLUMMET TO BETWEEN 5 AND 8 PERCENT AS TEMPERATURES WARM
INTO THE 90S TO NEAR 100. GIVEN PERSISTENT DROUGHT IN/CLOSE TO THE
AREA...AN EXTREME THREAT APPEARS JUSTIFIED.
...CRITICAL FIRE WEATHER AREA - ERN AZ/MUCH OF NM/SRN CO/SWRN
KS/MUCH OF THE OK AND TX PANHANDLES...
PRIMARY CONDITIONS: STRONG WINDS / LOW RH / LONG-TERM DRYNESS
OVERALL CONDITIONS WILL BE SIMILAR TO TUE...EXCEPT DISPLACED MORE TO
THE SE. WIDESPREAD STRONG WINDS AND LOW RH WILL BE LIKELY ACROSS THE
SRN ROCKIES INTO THE CNTRL/SRN HIGH PLAINS. SUSTAINED SURFACE SPEEDS
OF 20 TO 35 MPH WILL DEVELOP AS RH VALUES FALL TO AROUND 6 TO 12
PERCENT.
...CRITICAL FIRE WEATHER AREA - PORTIONS OF THE SACRAMENTO
VALLEY/COASTAL RANGES OF NRN CA...
PRIMARY CONDITIONS: MODERATE WINDS / LONG DURATION OF LOW RH /
MODERATE DROUGHT
SAN FRANCISCO AND SACRAMENTO VAD PROFILERS DEPICT A 40 MPH NLY LLJ
AND RECENT MESONET OBSERVATIONS CONFIRM GUSTY NLY WINDS LENDING TO
POOR RH RECOVERY...PRIMARILY ALONG AND WEST OF THE I-5 CORRIDOR TO
THE ERN SLOPES OF THE COASTAL RANGES. ALTHOUGH THE OVERALL SURFACE
PRESSURE GRADIENT WILL BE WEAKER COMPARED TO TUE...SUSTAINED SURFACE
WINDS AROUND 20 MPH ARE LIKELY THROUGH THIS MORNING AND THEN AGAIN
THIS EVENING OWING TO TYPICAL NOCTURNAL ENHANCEMENT. AFTERNOON RH
VALUES SHOULD DROP TO BETWEEN 4 AND 8 PERCENT WITH A RATHER LONG
DURATION OF RH AOB 15 PERCENT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0410 AM CDT WED JUN 11 2008
VALID 121200Z - 131200Z
...CRITICAL FIRE WEATHER AREA FOR N-CNTRL NM...
...SYNOPSIS...
DEEP UPPER-LEVEL LOW WILL PROGRESS SLOWLY E/NEWD FROM THE FAR NRN
HIGH PLAINS INTO MANITOBA BY EARLY FRI. BELT OF STRONGER MID-LEVEL
WLYS WILL STRETCH FROM THE GREAT BASIN ACROSS THE CNTRL PLAINS INTO
THE UPPER MS RIVER VALLEY THU AFTERNOON. WEAK LEE SURFACE LOW WILL
REMAIN CENTERED ACROSS THE SRN HIGH PLAINS WITH AN ATTENDANT FRONTAL
BOUNDARY ARCING TOWARDS THE LOWER MO RIVER VALLEY.
...CRITICAL FIRE WEATHER AREA - N-CNTRL NM...
PRIMARY CONDITIONS: MODERATE TO STRONG WINDS / LOW RH / LONG-TERM
DRYNESS
A WARM AND DRY AIR MASS WILL PERSIST ACROSS MUCH OF THE SOUTHWEST
THU AFTERNOON WITH RH VALUES AOB 15 PERCENT COMMON. HOWEVER...ANY
POTENTIAL FOR STRONG WINDS SHOULD BE RELEGATED TO NEAR THE UPPER RIO
GRANDE VALLEY AND LEE SLOPES OF THE SANGRE DE CRISTO MTNS OF N-CNTRL
NM. MODEL GUIDANCE REMAIN QUITE CONSISTENT WITH INDICATING THE
PERSISTENCE OF 500 MB WINDS AOA 60 MPH FROM THE FOUR CORNERS INTO
THE CNTRL PLAINS. ALTHOUGH LOW-LEVEL MASS FIELDS WILL NOT BE AS
CONDUCIVE FOR WIDESPREAD AND INTENSE WINDS AS IS EXPECTED TO OCCUR
ON DAY 1...DAYTIME MIXING SHOULD STILL RESULT IN SUSTAINED SURFACE
WINDS OF 20 TO 25 MPH AT PEAK HEATING.
...PORTIONS OF THE SACRAMENTO VALLEY AREA OF NRN CA...
OVERNIGHT RH RECOVERY SHOULD BE RATHER POOR GIVEN THE LIKLIHOOD OF
ONGOING GUSTY NLY WINDS WED NIGHT. THIS SHOULD AGAIN RESULT IN A
LONG DURATION OF CRITICALLY LOW RH AS ON DAY 1. HOWEVER...KINEMATIC
SUPPORT FOR STRONG WINDS WILL QUICKLY WANE THU AS MID-LEVEL JET AXIS
SHIFTS EWD INTO THE GREAT BASIN. THE CONTINUED PRESENCE OF A
MODERATE SURFACE PRESSURE GRADIENT SHOULD MAINTAIN LOCALLY GUSTY
WINDS WHERE FAVORABLE TERRAIN ENHANCEMENT OCCURS.
