The previous forecast (see below) remains on track, with no changes or additions made. ..Squitieri.. 03/02/2024 .PREV DISCUSSION... /ISSUED 0208 AM CST Sat Mar 02 2024/ ...Synopsis... An amplified large-scale trough accompanied by strong deep-layer west-southwesterly flow will move eastward across the western CONUS, with the leading edge of the strong flow aloft impinging on the Rockies during the afternoon hours. In response, a surface cyclone will rapidly deepen as it tracks slowly eastward across the northern Plains, while a deepening lee trough and tightening surface pressure gradient develop southward across much of the central and southern Plains. This large-scale pattern will result in an expansive area of warm, dry, and windy conditions across the central/southern High Plains, leading to a large area of elevated to high-end critical fire-weather conditions. ...Central and Southern High Plains... The strong deep-layer west-southwesterlies will support robust downslope warming/drying across the central and southern High Plains, where upper 60s to lower/middle 70s temperatures and 5-10 percent minimum RH is expected during the afternoon. At the same time, the tightening surface pressure gradient and deep boundary-layer mixing into the strong flow aloft will favor an expansive area of 25 mph sustained west-southwesterly surface winds (with gusts upwards of 40 mph). Over the I-25 corridor, gusts could reach 50-60 mph, though RH will be slightly higher compared to areas farther east over the Plains. Given mostly receptive fuels across the central and southern High Plains, high-end critical fire-weather conditions are expected -- with the most volatile fire-weather conditions expected over portions of southern CO, northeast NM, and the TX Panhandle. ...Please see www.spc.noaa.gov/fire for graphic product...
