DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0141 AM CDT THU APR 09 2026
VALID 101200Z - 111200Z
..SYNOPSIS
A LARGE UPPER-LEVEL TROUGH APPROACHES THE CALIFORNIA COAST ON
D2/FRIDAY AS ANOTHER UPPER TROUGH TRAVERSES THE GREAT LAKES INTO THE
NORTHEAST. SIMULTANEOUSLY, UPPER RIDGING WILL PERSIST ACROSS THE
ROCKIES AND EASTERN GREAT BASIN, WITH ZONAL FLOW CONTINUING ACROSS
THE GREAT PLAINS. AT THE SURFACE, A SLOW MOVING COLD FRONT WILL
PROGRESS SOUTHEASTWARD ACROSS THE OHIO RIVER VALLEY AND NORTHEAST
WITH HIGH PRESSURE BUILDING INTO THE GREAT LAKES/MIDWEST.
..PORTIONS OF THE GREAT BASIN
A TIGHTENED SURFACE PRESSURE GRADIENT WILL FAVOR SUSTAINED SOUTHERLY
WINDS OF 15-25 MPH ACROSS MUCH OF THE EASTERN/SOUTHERN GREAT BASIN
ON D2/FRIDAY. DESPITE SOME MID/HIGH CLOUD COVER, RH VALUES ARE
FORECAST TO FALL TO 15-20% (LOCALLY DOWN TO 10%) DURING PEAK MIXING
FRIDAY AFTERNOON. WITH PRECONDITIONED, DRYING FUELS FROM
D1/THURSDAY, THIS COMBINATION OF WINDS AND RH IS EXPECTED TO SUPPORT
ELEVATED FIRE WEATHER CONDITIONS ACROSS MUCH OF EASTERN UTAH INTO
WEST-CENTRAL/NORTHWESTERN COLORADO. DEEP BOUNDARY LAYER MIXING AND
MODESTLY STRONG MID-LEVEL FLOW (25-35 KTS WITHIN THE 700-500 MB
LAYER) WILL ALSO SUPPORT THE POTENTIAL FOR OCCASIONAL GUSTS TO 35
MPH ACROSS THIS REGION. EXPECTED PRECIPITATION ARRIVAL ON SATURDAY
MAY PROVIDE RELIEF TO ANY ONGOING OR NEW FIRE STARTS.
