CRITICAL FIRE WEATHER AREA ... && ####018001801#### FNUS28 KWNS 102010 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0308 PM CDT Sat May 10 2025 Valid 121200Z - 181200Z The high-over-low block across the eastern United States should break down early next week as a trough moves through the West and helps open the closed low across the northern Gulf states. Before the Rex block breaks down on Monday, another hot, dry day across the northern Plains will result in elevated to potentially critical fire weather conditions. A corridor of winds greater than 20 mph is possible from north-central Nebraska northward into western Minnesota. However, relative humidity values on Monday (Day-3) should be higher than the previous day, which may temper the overall large-scale fire concerns. That said, fuels should be slightly drier than the day before owing to continued drying. Balancing this, this forecast opts to expand the 40% area and hold off on introducing critical highlights. Across the Southwest, a tightening midlevel height gradient between the approaching/developing trough and the subtropical ridge will result in increasing midlevel flow across the Southwest. As this midlevel flows mixes to the surface, afternoon wind speeds and relative-humidity values will fall to critical levels (greater than 20 mph and less than 15-percent respectively). However, fuels across much of the Southwest have not begun to cure/are still relatively moist. The exception to this is across southeast Arizona and southern New Mexico. A 40% probability of critical fire weather conditions remains across this area for Tuesday and Wednesday (Days 4 and 5). ..Marsh.. 05/10/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
