SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0156 AM CDT Tue Mar 19 2024 Valid 191200Z - 201200Z ...NO CRITICAL AREAS... ...Synopsis... A split flow regime will develop over the U.S. throughout the day with a belt of northwesterly flow in the Midwest and subtropical westerlies at lower latitudes. No widespread areas of Elevated fire-weather conditions are expected, although some localized gusty and dry conditions may develop in portions of the Appalachians and High Plains. ...Ohio River Valley southward through western NC and SC... As a cold front continues to push southeastward through the East Coast and FL Peninsula, locally stronger post-frontal surface winds could yield Elevated fire-weather conditions in regions of locally drier fuels. The lowest relative humidities are expected from the Ohio River Valley southward through western NC and SC along the eastern slopes of the Appalachians. Low confidence exists regarding the overlap of strongest surface winds, drier conditions, and receptive fuels, precluding any Elevated areas at this time. ...Southern High Plains... The surface pattern across the Southern High Plains will be influenced by steady, post-frontal high pressure along the Gulf Coast and a developing, mid-level cutoff low over the Four Corners region. This will yield gradual moisture return across the Southern Plains, bounded to the west by drier southwesterly flow. Locally windy (around 15+ mph) and dry (relative humidities around 20-25 percent) conditions may develop across portions of the TX/OK Panhandles. Some precipitation has occurred across the region in the last few days, but locally drier fuels may support pockets of heightened fire-weather conditions on Tuesday afternoon. ..Flournoy.. 03/19/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
