NWS STORM PREDICTION CENTER NORMAN OK

VALID 281200Z - 291200Z
..GREAT BASIN AND SOUTHWEST
AN UPPER-LEVEL LOW ANCHORED OVER THE SIERRA NEVADA AND CORRESPONDING
SURFACE LOW OVER WESTERN ID WILL CONTINUE TO POSE A FIRE WEATHER
THREAT TO PORTIONS OF THE GREAT BASIN AND SOUTHWEST D2/THURSDAY.
BREEZY SOUTH WINDS OF 15-25 MPH, RELATIVE HUMIDITY AS LOW AS 10% IN
VALLEYS AND DRY/CURED FUELS IN LOWER ELEVATIONS WILL SUPPORT AN
ENHANCED FIRE WEATHER CONCERN ACROSS PORTIONS OF AZ AND FAR WESTERN
NM INTO THE EASTERN GREAT BASIN AND CO WESTERN SLOPE. ELEVATED
HIGHLIGHTS WERE EXTENDED NORTHWARD INTO FAR SOUTHERN ID WHERE RECENT
FIRE ACTIVITY AMID LOCALLY DRIER FUELS EXIST. ADDITIONAL EXPANSION
FARTHER INTO CENTRAL UT WAS WARRANTED BASED ON LATEST FORECAST
GUIDANCE.
..NORTHEASTERN MONTANA
SURFACE TROUGHING EXTENDING FROM ID INTO THE NORTHERN ROCKIES AND
SURFACE HIGH PRESSURE SETTLING INTO THE GREAT LAKES WILL MAINTAIN A
DRY SOUTHEASTERLY FLOW ACROSS PORTIONS OF THE NORTHERN HIGH PLAINS
D2/THURSDAY. THE ALIGNMENT OF RECEPTIVE FUELS, SOUTHEAST WINDS OF
15-20 MPH AND DAYTIME RELATIVE HUMIDITY AROUND 20% WILL SUPPORT
ELEVATED FIRE WEATHER CONDITIONS ACROSS NORTHEASTERN MT.

..SYNOPSIS
A SIMILAR SYNOPTIC SETUP AS D1/WEDNESDAY WILL CARRY OVER INTO
D2/THURSDAY AS A NEARLY STATIONARY UPPER LOW REMAINS OVER CA/GREAT
BASIN, AND UPPER RIDGING PERSISTS ACROSS THE CENTRAL CONUS. THE MAIN
TROUGH AXIS WILL GRADUALLY LIFT INTO THE CENTRAL PLAINS WHILE
MOISTURE ADVECTION OCCURS DOWNSTREAM OF THE UPPER LOW, ENCOURAGING
CONTINUED CHANCES FOR PRECIPITATION IN THE HIGH PLAINS. BENEATH
UPPER TROUGHING, A COLD FRONT IS EXPECTED TO PROGRESS SOUTHWARD
ACROSS THE MID-ATLANTIC BRINGING BELOW-NORMAL TEMPERATURES AND
ADDITIONAL OPPORTUNITIES FOR SPOTTY PRECIPITATION TO THE EASTERN
SEABOARD.
..GREAT BASIN AND SOUTHWEST
PROLONGED SOUTHWESTERLY FLOW WILL MAINTAIN FIRE WEATHER CONCERNS FOR
PARTS OF THE GREAT BASIN, UPPER CO RIVER BASIN, AND PORTIONS OF THE
SOUTHWEST THROUGH DAY 2/THURSDAY. SOUTHERLY SUSTAINED WINDS OF 15-25
MPH AND RH VALUES AROUND 15% COMBINED WITH DRIER LOWER ELEVATION
FUELS ARE EXPECTED TO PROMOTE ELEVATED FIRE WEATHER CONDITIONS
DURING THE AFTERNOON.
..NORTHEASTERN MONTANA
AHEAD OF A PERSISTENT SURFACE TROUGH, DRY SOUTHEASTERLY FLOW OVER
THE NORTHERN HIGH PLAINS WILL SUPPORT ANOTHER DAY OF ENHANCED FIRE
WEATHER CONCERNS ACROSS NORTHEASTERN MT ON DAY 2/THURSDAY. ELEVATED
HIGHLIGHTS HAVE BEEN INTRODUCED TO NORTHEASTERN MT WHERE RECEPTIVE
FUELS ARE STILL PRESENT WITHIN POCKETS OF GREEN UP.
