DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0130 AM CDT MON AUG 11 2008
VALID 111200Z - 121200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
IN THE WEST...THE UPPER LOW NOW MOVING INTO ALBERTA WILL SLOWLY
PROGRESS EWD INTO SASKATCHEWAN. STRONGER WINDS IN ASSOCIATION WITH
THIS SYSTEM WILL MAINLY BE CONFINED CLOSER TO THE U.S./CANADIAN
BORDER...WHERE RELATIVE HUMIDITIES WILL BE MARGINAL. UPPER RIDGING
WILL SLOWLY BUILD OVER THE WEST FOLLOWING THIS SYSTEM...WITH HOT AND
DRY CONDITIONS OVER A WIDESPREAD AREA.
IN THE FOUR CORNERS REGION...AREAS WEST WILL CONTINUE TO TRANSITION
INTO A DRIER REGIME AS EVIDENCED BY RECENT PWAT TRENDS/WV IMAGERY.
AFTERNOON THUNDERSTORMS WILL MAINLY BE CONFINED TO SERN AZ NEWD
THROUGH THE ROCKIES.
MEANWHILE IN THE EAST...AN UPPER/SFC LOW WILL GRADUALLY MOVE
OFFSHORE...AND DRY CONDITIONS WILL FOLLOW THE FRONTAL PASSAGE ACROSS
INLAND AREAS IN THE MID ATLANTIC. HOWEVER...RELATIVE HUMIDITIES ARE
EXPECTED TO STAY ABOVE CRITICAL THRESHOLDS AND WINDS WILL GENERALLY
BE LIGHT. PREVIOUS RAINFALL SHOULD HELP TO MITIGATE THE OVERALL
THREAT AS WELL.
...PORTIONS OF ID/WRN WY/WRN MT...
TEMPERATURES WILL BE SLIGHTLY WARMER COMPARED TO YESTERDAY...AND
RELATIVE HUMIDITIES WILL ONCE AGAIN DROP INTO THE TEENS BY THE
AFTERNOON...MAINLY IN THE LOWER VALLEYS. ALTHOUGH SUSTAINED WINDS
APPEAR TO BE MARGINAL...GUSTY WINDS NEAR 25 TO 30 MPH MAY BE
POSSIBLE IN THE AFTERNOON. DUE TO PREVIOUS RAINFALL...THE FIRE
THREAT WILL BE SOMEWHAT MITIGATED.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0231 AM CDT MON AUG 11 2008
VALID 121200Z - 131200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
LARGE SCALE PATTERN WILL REMAIN VERY SIMILAR...WITH THE UPPER TROUGH
DOMINATING THE EAST...AND UPPER RIDGING DOMINATING MUCH OF THE WEST.
UPPER RIDGING WILL SLOWLY STRENGTHEN OVER THE SOUTHWESTERN
STATES...AND IN COMPARISON TO DY1...TEMPERATURES WILL BE A FEW
DEGREES WARMER AT THE SURFACE IN RESPONSE.
IN WA/OR...A SHORT WAVE APPROACHING THE COAST WILL INCREASE SWLY
WINDS. ISOLATED DRY THUNDERSTORMS MAY ALSO BE POSSIBLE...MAINLY NEAR
THE CASCADES.
...WA/OR...
THERE IS CONSIDERABLE UNCERTAINTY IN REGARDS TO A SHORT WAVE THAT
WILL REACH THE COAST BY DY2. MOVEMENT OF THE UPPER LOW...NOW
SHIFTING EWD INTO ALBERTA...WILL ALLOW UPPER RIDGING TO BRIEFLY
BUILD OVER WA/OR TODAY. FOLLOWING THIS RIDGE...ANOTHER SHORT WAVE
TROUGH APPROACHING THE BRITISH COLUMBIA COAST IS EVIDENT ON WV
IMAGERY THIS MORNING. CURRENT FORECASTS INDICATE THAT RELATIVE
HUMIDITIES WILL BE MARGINAL. DESPITE THIS...THERE MAY BE A SMALL
AREA ON THE LEE OF THE CASCADES AND AT HIGHER ELEVATIONS THAT WILL
EXPERIENCE SUSTAINED WINDS NEAR 20 MPH WITH STRONGER GUSTS.
ADDITIONALLY...SHOULD MID LEVEL MOISTURE OBSERVED ROTATING AROUND
THE BASE OF THE TROUGH REACH WA/OR AT FAVORABLE HEATING...ISOLD DRY
THUNDERSTORMS MAY BE POSSIBLE. ATTM...FORECAST SOUNDINGS INDICATE
MINIMAL INSTABILITY...WHILE ENSEMBLE FORECASTS ARE ON THE LOWER END
OF THIS PROBABILITY AS WELL. THIS AREA WILL BE REEXAMINED IN
TOMORROWS FORECAST.
