DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0153 AM CDT TUE JUL 08 2025
VALID 091200Z - 101200Z
..SYNOPSIS
A COMPACT MIDLEVEL TROUGH WILL TRACK EASTWARD ACROSS THE NORTHWEST
DURING THE DAY -- IN TANDEM WITH A ROBUST MIDLEVEL TROUGH/LOW MOVING
EASTWARD FROM BRITISH COLUMBIA INTO ALBERTA. LARGE-SCALE ASCENT
PRECEDING THE MIDLEVEL TROUGH MOVING ACROSS THE NORTHWEST WILL
PROMOTE ANOTHER DAY OF ISOLATED HIGH-BASED THUNDERSTORMS -- WITH A
FOCUS OVER SOUTHEASTERN OR INTO SOUTHWESTERN ID. DEEP INVERTED-V
SOUNDINGS AND PW AROUND 0.7 INCHES WILL FAVOR DRY THUNDERSTORMS
CAPABLE OF PRODUCING LIGHTNING-INDUCED IGNITIONS AND STRONG/ERRATIC
OUTFLOW WINDS.
SIMILAR TO DAY 1/TUESDAY, A BELT OF STRONG DEEP-LAYER WESTERLY FLOW
(PERIPHERAL TO THE MIDLEVEL TROUGH) ACROSS THE CASCADES WILL LEAD TO
BREEZY/GUSTY WESTERLY SURFACE WINDS IN THE COLUMBIA BASIN. WHILE
INCREASING BOUNDARY-LAYER MOISTURE WILL LIMIT RH REDUCTIONS COMPARED
TO DAY 1/TUESDAY, STRONGER SURFACE WINDS WILL OFFSET THIS AND STILL
YIELD ELEVATED FIRE-WEATHER CONDITIONS.
OVER THE GREAT BASIN, MODERATE MIDLEVEL SOUTHWESTERLY WINDS
ACCOMPANYING THE COMPACT MIDLEVEL TROUGH WILL OVERSPREAD THE GREAT
BASIN DURING THE DAY. DEEP BOUNDARY-LAYER MIXING INTO THIS
STRENGTHENING FLOW ALOFT WILL SUPPORT ANOTHER DAY OF ELEVATED TO
LOCALLY CRITICAL FIRE-WEATHER CONDITIONS, GIVEN INCREASINGLY
DRY/RECEPTIVE FUELS.
