DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0144 AM CDT MON JUN 15 2026
VALID 161200Z - 171200Z
..SYNOPSIS
ALONG THE NORTHEASTERN PERIPHERY OF AN UPPER RIDGE OVER THE WEST, A
MIDLEVEL TROUGH AND ACCOMPANYING 70-80-KT SPEED MAX WILL ADVANCE
SOUTHEASTWARD ACROSS THE NORTHWEST AND NORTHERN ROCKIES ON TUESDAY.
IN RESPONSE, A SURFACE LOW WILL DEEPEN WHILE ADVANCING
EAST-SOUTHEASTWARD ACROSS THE NORTHERN PLAINS.
..NORTHERN INTERMOUNTAIN WEST
ON THE SOUTHERN EDGE OF THE ROBUST MIDLEVEL SPEED MAX, STRONG
DEEP-LAYER WEST-NORTHWESTERLY FLOW WILL OVERSPREAD A WARM/DRY AIR
MASS DURING THE AFTERNOON. THIS, COMBINED WITH A TIGHTENING PRESSURE
GRADIENT, WILL RESULT IN 15-25 MPH SUSTAINED WESTERLY SURFACE WINDS
AMID 15-20 PERCENT AFTERNOON RH. GIVEN INCREASINGLY DRY/RECEPTIVE
FUELS ACROSS THE REGION, ELEVATED TO LOCALLY CRITICAL FIRE-WEATHER
CONDITIONS ARE EXPECTED. IN PARTICULAR, LOCALLY CRITICAL CONDITIONS
ARE MOST LIKELY IN THE GAP-FLOW AREAS THROUGH THE CASCADES AND THE
SNAKE RIVER PLAIN. HOWEVER, THESE CONDITIONS APPEAR TOO LOCALIZED
FOR CRITICAL HIGHLIGHTS AT THIS TIME.
..EASTERN GREAT BASIN INTO THE ROCKIES AND ADJACENT PLAINS
DESPITE RELATIVELY WEAKER MIDLEVEL FLOW COMPARED TO AREAS NORTH AND
NORTHWEST, AT LEAST MODERATE MIDLEVEL FLOW WILL PROMOTE AN EXPANSIVE
AREA OF BREEZY/GUSTY WEST-NORTHWESTERLY SURFACE WINDS ACROSS THE
REGION. THESE BREEZY/GUSTY WINDS COUPLED WITH SINGLE-DIGIT TO
LOWER-TEENS RH WILL YIELD BROAD ELEVATED FIRE-WEATHER CONDITIONS
DURING THE AFTERNOON. STRONGER DEEP-LAYER FLOW IN CLOSER PROXIMITY
TO THE MIDLEVEL SPEED MAX WILL FAVOR STRONGER SUSTAINED SURFACE
WINDS (AROUND 20-25 MPH) OVER PARTS OF SOUTHERN WY, WHERE LOCALLY
CRITICAL CONDITIONS ARE POSSIBLE. LOCALLY CRITICAL CONDITIONS WILL
ALSO BE POSSIBLE IN TERRAIN-FAVORED AREAS THROUGHOUT THE ELEVATED
AREA.
