Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0201 PM CDT Mon May 19 2025 Valid 201200Z - 211200Z ...NO CRITICAL AREAS... The main change made to the Day 2 Fire Weather Outlook Update was to add Elevated highlights to portions of Minnesota. Here, deep-layer easterly flow north of both a surface low, and developing mid-level cyclone over the Midwest, will encourage dry and breezy conditions by afternoon. 15-20 mph sustained easterly surface winds will coincide with 20-30 percent RH as the boundary layer mixes, supporting elevated conditions atop fuels that are at least marginally supportive of wildfire spread. Across the rest of the CONUS, the previous forecast (see below) remains on track. ..Squitieri.. 05/19/2025 .PREV DISCUSSION... /ISSUED 0200 AM CDT Mon May 19 2025/ ...Synopsis... A large-scale trough will deamplify as it advances eastward into the eastern half of the CONUS on Tuesday. On the backside of this system, dry/breezy post-frontal conditions will develop across parts of the central Plains. However, preceding rainfall and a marginal spatial overlap of the breezy winds and low RH should limit the overall fire-weather risk. Broad/enhanced westerly flow will continue to support dry conditions across the Southwest into the southern High Plains, though surface winds will weaken compared to Monday, as the strongest midlevel flow shifts eastward with the midlevel trough. ...Please see www.spc.noaa.gov/fire for graphic product...
