DAY 2 FIRE WEATHER OUTLOOK

VALID 081200Z - 091200Z
..NO CRITICAL AREAS
NO CHANGES ARE NEEDED TO THE D2 FIRE WEATHER OUTLOOK. THUNDERSTORMS
WILL CONTINUE ACROSS THE PACIFIC NORTHWEST, WITH INCREASING CHANCES
FOR WETTING RAINFALL. LATEST INTEL FROM PARTNERS SUGGEST MANY
ONGOING FIRES HAVE RECEIVED RAINFALL OVER THE LAST 24-48 HOURS.
HI-RES GUIDANCE INDICATES THAT ACTIVITY FOR D1/SUNDAY WILL BE A MIX
OF WET/DRY, WITH ADDITIONAL WETTING RAINFALL LIKELY. IN ADDITION,
INCREASING HUMIDITY AND CLOUD COVER AMID LOWER MIXING HEIGHTS HAS
HELPED IMPROVE FIRE CONDITIONS. GUSTY AND ERRATIC OUTFLOW FROM
NEARBY THUNDERSTORMS MAY IMPACT ONGOING FIRES.
THE EXCEPTION MAY BE ACROSS A SMALL PORTION OF NORTHEASTERN OREGON,
WHERE LESS RAINFALL HAS BEEN RECORDED AND AMOUNTS ARE GENERALLY
EXPECTED TO BE LESS THAN 0.10-0.25" TOMORROW. IN THIS REGION, LOW
PROBABILITY OF NEW IGNITIONS STILL REMAINS POSSIBLE. OVERALL, THIS
AREA REMAINS TOO CONFINED AND UNCERTAIN FOR INCLUSION OF ANY AREAS
AT THIS TIME.

..SYNOPSIS
A MID-LEVEL TROUGH WILL OVERSPREAD THE WESTERN U.S. AS UPPER RIDGING
BUILDS INTO THE PLAINS STATES TOMORROW (MONDAY). ANOTHER DAY OF
LOCALLY DRY AND BREEZY CONDITIONS IS EXPECTED ACROSS THE GREAT
BASIN, THOUGH WIDESPREAD AND LONGER-LASTING WINDS/RH REACHING
ELEVATED CRITERIA APPEARS LESS LIKELY. THUNDERSTORMS, DRIVEN BY
STRONG FORCING FOR ASCENT WITH THIS UPPER TROUGH, WILL DEVELOP OVER
THE WINDWARD SIDE OF THE CASCADES AND PROGRESS EASTWARD THROUGH THE
DAY. HOWEVER, FUELS ARE MOST RECEPTIVE TOWARD THE NORTHERN ROCKIES.
STORMS SHOULD APPROACH THE NORTHERN ROCKIES AFTER DARK, THOUGH IT IS
UNCLEAR HOW DRY THEY WILL BE, AND HOW MUCH OVERLAP WILL OCCUR WITH
THE MOST RECEPTIVE FUELS, PRECLUDING ISOLATED DRY THUNDERSTORM
HIGHLIGHTS THIS OUTLOOK.
