A mid to upper-level shortwave trough will traverse the Central Plains and Midwest D3/Sunday. Thereafter, the synoptic pattern will become fairly persistent with a long-wave trough encompassing the eastern half of CONUS, and ridging present over the Rockies and Southwest. ...Central and Southern Plains... A deepening surface cyclone over the Upper Midwest is expected to accompany the aforementioned shortwave trough D3/Sunday. An associated tightening pressure gradient across the Central and Northern Great Plains will support breezy west-northwest surface winds there, while a cold front dives south in the lee of the Rockies into the Southern Plains. Although RH will likely remain just above critical thresholds within a cooler air mass, these areas continue to remain unseasonably dry with receptive fuels for fire ignition and spread present. Therefore, two low probability areas for critical fire weather conditions have been introduced from western NE/northern KS, and western OK/northwestern TX. By D4/Monday a surface high over the Missouri River Valley will migrate slowly southward, shunting low-level moisture to the Gulf coast. Meanwhile, lee troughing will commence across the High Plains with accompanying southerly surface winds developing within dry antecedent conditions over western OK. A 40% area has been introduced here for D4/Monday, as projected ERC percentile estimates continue to indicate receptive fuel states across this region. Another cold front will result in breezy northwest winds developing across the Central Plains (NE) D5/Tuesday, and although a cooler air mass should keep relative humidity from falling into critical limits, deteriorating fuel conditions are anticipated given a lack of rainfall. After early next week, rainfall probabilities will begin to increase across most of the CONUS along frontal boundaries and in association with a southern stream Pacific shortwave trough entering the Southern Plains. This should limit the overall potential for significant fire weather concerns. ..Barnes/Williams.. 03/21/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
