The previous forecast remains on track. The only changes made to the current forecast were to expand Elevated highlights farther south into Far West Texas, with expansions also made farther east into northwestern Oklahoma. Critical highlights were also expanded farther north into eastern Colorado, and farther east into western Kansas. Expansions were made to reflect the latest guidance consensus in dry and windy conditions supporting wildfire spread tomorrow/Saturday afternoon. ..Squitieri.. 03/01/2024 .PREV DISCUSSION... /ISSUED 0211 AM CST Fri Mar 01 2024/ ...Synopsis... An amplified large-scale trough accompanied by strong deep-layer west-southwesterly flow will overspread the western CONUS, with the leading edge of the strong flow aloft crossing the Rockies during the afternoon. At the same time, a lee surface cyclone will rapidly deepen over the northern High Plains, while a lee trough and tight surface pressure gradient develop southward along the central/southern High Plains. This evolution will lead to a large area of strong/gusty west-southwesterly surface winds and low RH across much of the High Plains, where elevated to critical fire-weather conditions are expected. ...Central and Southern High Plains... Strong downslope flow and deep boundary-layer mixing across the central/southern High Plains will support an expansive area of 10-percent minimum RH and temperatures in the upper 60s to low/mid 70s despite increasing high-level clouds ahead of the large-scale trough. Here, the tightening surface pressure gradient and mixing into the strong flow aloft will favor widespread 20-25 mph sustained west-southwesterly surface winds (with higher gusts). Given drying of fine fuels across the region on D1/Friday, Critical fire-weather conditions are expected across portions of eastern CO, northeast NM, the TX/OK Panhandles, far western OK, and far southwest KS. ...Please see www.spc.noaa.gov/fire for graphic product...
