####018002033#### FNUS21 KWNS 150604 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0104 AM CDT Thu May 15 2025 Valid 151200Z - 161200Z ...Synopsis... An upper trough will quickly move eastward over the central US with accompanying strong mid-level flow. A deepening lee cyclone will intensify further as it move into the Upper Midwest tonight. As the low deepens, a Pacific cold front and tailing dryline will move quickly through the Rockies, into the Plains and Midwest States. Cooler temperatures, gusty westerly winds and some precipitation are possible along and behind the front through tonight. Elevated fire-weather conditions are possible over parts of the southern Plains and Southwest. ...Southwest... Persistent westerly flow will continue across the Southwest today and tonight as a weak pacific front moves over the Rockies. This will support another day of dry and windy conditions across parts of eastern AZ and southern NM. Despite somewhat cooler temperatures behind the front, downsloping and deep vertical mixing will support RH below 20% and winds of 15-20% amidst dry fuels. Widespread elevated to locally critical conditions are expected. Some fire-weather risk may also extend into West TX behind an eastward mixing dryline. However, winds here may be somewhat weaker despite very warm surface temperatures and lower humidity. Locally elevated conditions are possible within drying fuels. ...Central plains and Midwest... Gusty westerly winds are possible behind the advancing cold front from parts of the central Plains into western IA and MO this afternoon. While gusts may reach 20-25 mph, RH values are not expected to be critical with cooler temperatures. Additionally, recent wetting rainfall may temporarily limit available fuels. This suggests any fire-weather concerns will be localized and short lived. ..Lyons.. 05/15/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018001137#### FNUS22 KWNS 150605 FWDDY2 Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0104 AM CDT Thu May 15 2025 Valid 161200Z - 171200Z ...NO CRITICAL AREAS... ...Synopsis... Fire-weather potential across the CONUS is relatively low Friday. In the wake of the departing upper trough, shortwave ridging is expected over the southern Plains and Southwest. This will temporarily slow stronger mid-level flow as a Pacific front shifts eastward. With only modest flow aloft and at the surface, strong winds are not expected over the driest fuels of the Southwest. However, warm temperatures and low RH below 20% will remain likely. This could support some localized fire-weather risk where westerly winds could gust to 15 mph closer to the terrain. Otherwise, increasing surface moisture and recent rainfall will largely preclude fire-weather concerns Friday outside of localized dry and breezy conditions over parts of the Midwest. However, this is not expected to be widespread. ..Lyons.. 05/15/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
