| ZCZC SPCFWDDY2 ALL FNUS22 KWNS 240700 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0200 AM CDT Sun May 24 2026 Valid 251200Z – 261200Z …CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NORTHWESTERN NEVADA INTO SOUTHEASTERN OREGON… …Synopsis… A potent mid-level trough will move onshore of the Pacific Northwest on D2/Monday as a second mid-level trough transitions northeastward across northern New England. Weak troughing will also persist across the lower Mississippi Valley/southern Plains and across the Southwest. Meanwhile, upper-level ridging will remain in place across the Southeast and central/northern Plains. A surface low will track offshore of New England, with a trailing cold front progressing through the Mid-Atlantic before extending southwestward into the southern Plains. A cold front will also begin to advance eastward across the Pacific Northwest in tandem with a deepening surface low. …Great Basin… A strengthening surface pressure gradient ahead of the approaching cold front will promote sustained southwesterly surface winds of 20-25 mph, with above normal temperatures and minimum RH values of 10-15% also expected. Recent fire activity suggests that fuels are becoming more receptive to wildfire spread across this region. Thus, these conditions are expected to support a corridor of critical fire weather concerns from northwestern Nevada into southeastern Oregon Monday afternoon. Sustained southwesterly winds of 15-25 mph overlapping reduced RH of 15-25% will also promote elevated fire weather conditions across adjacent areas of the Great Basin. …Southwest… A mid-level shortwave trough and accompanying subtropical moisture plume will contribute to weak buoyancy atop well-mixed boundary layer profiles. This is expected to support widely scattered, high-based convection across much of northeastern Arizona and western New Mexico Monday afternoon. PWAT values ranging from 0.4-0.7″ (locally up to 1″) and more marginal LCLs ranging from 2-3+ km AGL will likely favor a mix of wet and dry thunderstorms. Given that fuels across the region remain quite dry (ERCs around the 90th percentile), isolated lightning ignitions remain possible. Thus, the 10% dry thunderstorm probability has been maintained for this update. ..Chalmers.. 05/24/2026 …Please see http://www.spc.noaa.gov/fire for graphic product… CLICK FOR DAY 2 FIREWX AREAL OUTLINE PRODUCT (KWNSPFWFD2) |
