Administrators NorthGeorgiaWX Posted October 29 Administrators Posted October 29 SPC Day 1 Fire Weather Outlook Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0204 AM CDT Tue Oct 29 2024 Valid 291200Z - 301200Z ...CRITICAL FIRE WEATHER AREA FOR PARTS OF THE SOUTHERN AND CENTRAL HIGH PLAINS... ...Synopsis... Ahead of a deepening upper trough over the western US, strong southwesterly flow aloft will overspread the Rockies and adjacent High Plains. A lee low and trailing surface trough will encourage strong downslope winds of 20-30 mph across eastern CO/NM and parts of western KS, TX and OK. Farther east, strong southerly surface winds and dry conditions will be in place over parts of the Midwest. Widespread elevated to critical fire-weather conditions are likely. ...High Plains... As the upper trough approaches from the west, mid-level flow will continue to intensify over the southern Rockies and High Plains. The strong lee low over eastern CO will continue to deepen and shift eastward with strong southwesterly surface winds across the warm sector. Dry downslope winds of 25-35 mph and RH values below 20% will support several hours of widespread elevated to critical fire-weather conditions. The greatest overlap of critical meteorological conditions and receptive fuels appears to be across parts of eastern CO and far western KS. However, given the strength of the low-level wind fields and low humidity, critical conditions may occur as far south as parts of the TX/OK Panhandles for a few hours. Locally elevated fire-weather conditions may also occur across parts of central/northern NM closer to the upper low. Strong flow aloft will bolster surface winds to around 15-20 MPH with low RH. While fuels are somewhat mixed here, at least a few hours of locally elevated fire-weather conditions are possible before the cold front passes. ...Midwest... Elevated fire-weather conditions are possible in parts of the Midwest ahead of the deepening surface low over the Plains. Models show a drier pocket of air moving over parts of central IL and IN by this afternoon. Fuels are near record dry and winds will be strong with southerly gusts of 15-20 mph. Though drier than normal, low-level humidity is only expected to be around 30%. Uncertainty remains quite large due to potential cloud cover and the marginal RH values, but a few hours of elevated fire-weather conditions are possible given expected strong winds and dry fuels. ..Lyons.. 10/29/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
