124 FNUS21 KWNS 281650 FWDDY1 Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1050 AM CST Fri Feb 28 2025 Valid 281700Z - 011200Z ...17z Update... A dry cold frontal passage and strong surface cyclogenesis should support several hours of elevated to near-critical fire-weather conditions over parts of the Plains and Midwest this afternoon. Morning observations show strong northwesterly winds of 20-25 mph overspreading the central Plains. As temperatures warm this afternoon RH values should fall below 35%. Despite marginal RH, strong surface winds will continue this afternoon and compensate to support the potential for rapid wildfire spread over portions of the Plains states into the Midwest, where some wildfire activity has already been observed. The Elevated area was expanded over parts of NE and KS where winds are expected to be stronger. See the prior outlook. ..Lyons.. 02/28/2025 .PREV DISCUSSION... /ISSUED 0135 AM CST Fri Feb 28 2025/ ...Synopsis... A mid-level trough will amplify across the eastern half of the CONUS today, encouraging the rapid eastward translation of a broad surface low over the Great Lakes. A large area of strong isallobaric surface flow is expected across the Plains states into portions of the Midwest. By afternoon, sustained westerly surface winds in the 20-30 mph range will overspread much of South Dakota into Nebraska, Iowa, and northern Missouri. Meanwhile, a belt of 15-20 mph sustained southwesterly surface winds are likely across the Texas Panhandle toward eastern Missouri/western Illinois. RH will dip to 20-30 percent across the Southern Plains, with only 30-40 percent RH dips likely across South Dakota into the Midwest. Despite marginal RH, strong surface winds will compensate to support the potential for rapid wildfire spread over portions of the Plains states into the Midwest, where some wildfire activity has already been observed in lieu of stronger surface winds. ...Please see www.spc.noaa.gov/fire for graphic product... $$
