FNUS21 KWNS 300704 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0203 AM CDT Wed Oct 30 2024 Valid 301200Z - 311200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHERN PLAINS... ...Synopsis... A strong upper trough will intensify further as it ejects eastward over the central US today and tonight. Strong mid-level flow will accompany the trough, deepening a lee low over parts of CO/KS. The low will move northeast along a cold front across KS and OK, drawing an unusually moist air mass northward across the eastern Plains. To the west, dry and breezy conditions are likely over parts of TX and western OK, as well as the Midwest and Great Lakes. Elevated to critical fire-weather conditions are possible. ...Southern Plains... As the upper trough ejects eastward a 70-80 kt mid-level jet will round the base of the trough over the southern and central High Plains. West of a lee low and intensifying dryline, downslope winds of 25-35 mph are likely across much of the eastern Panhandle and western OK. Aided by mid-level subsidence and unusually warm temperatures in the mid to upper 80s F, afternoon RH values of 8-15% are expected through peak heating. The overlap of several hours of hot, dry and windy conditions over very dry fuels lends higher confidence in sustained critical fire-weather conditions this afternoon. Additionally, the cold front trailing the low will pass over the High Plains later this evening. A notable wind shift to north/northwesterly is expected after 00z. Strong winds could continue into the overnight hours exacerbating fire concerns despite increasing RH. ...Great Lakes... Dry and windy conditions are possible ahead of the deepening trough over parts of the Great Lakes and Midwest today. While RH values should steadily increase as moisture advects northward, sustained southerly winds near 15-20 mph will overlap with extremely dry fuels. While clouds and the increasing moisture should limit marginal RH, a few hours of locally elevated fire-weather conditions are possible this afternoon given the strong winds and unusually dry fuels. ..Lyons.. 10/30/2024 ...Please see www.spc.noaa.gov/fire for graphic product... $$
