A northern-stream midlevel shortwave trough will track eastward across the northern Plains, while an attendant surface cyclone and trailing cold front move east-northeastward across the Dakotas early in the period. Along/ahead of the front, a tightening surface pressure gradient, coupled with boundary-layer mixing into a 45-50 kt low-level jet, will yield 20-25 mph sustained southerly surface winds (with gusts upwards of 45 mph) across parts of eastern SD, western MN, northeast NE, and far northwest IA. Here, 25-35 percent minimum RH will support an elevated to near-critical fire-weather risk, given the strong/gusty surface winds atop modestly receptive fuels. Farther south, midlevel westerly flow will strengthen across the southern Rockies -- ahead of an approaching midlevel trough/low moving ashore over southern CA. The strengthening downslope flow off the southern Rockies, and related lee cyclogenesis over eastern CO, will favor 15-20 mph sustained southwesterly surface winds (with higher gusts) amid 15-20 percent afternoon RH across the southern High Plains. As a result, elevated to spotty critical fire-weather conditions are expected. ..Weinman.. 03/06/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
