Fire weather concerns are expected to remain limited on Sunday across most of the country, though localized concerns may emerge across parts of the southern High Plains. The dry air mass currently in place across the Southwest and southern High Plains will largely remain in place over the next 48 hours. Meanwhile, the upper low currently moving onshore across CA is forecast to reach the southern Rockies by around peak heating Sunday afternoon. Westerly mid-level winds are forecast to strengthen as result, but the lack of an appreciable mixed layer over the southern Rockies will likely modulate the depth of boundary-layer mixing and subsequently the degree of downward momentum transfer. Additionally, the arrival of a weak cold front (currently moving south across the northern Plains as of early Saturday morning) and building surface high pressure across the southern Plains should be a limiting factor for strong gradient winds. Consequently, the strongest wind gusts should manifest along, and in the lee of, more prominent terrain features. Recent ensemble guidance appears to capture this trend well with high probabilities for winds above 20 mph noted from the Sacramento Mountains in southern NM to the Davis Mountains in southwest TX. Given the antecedent dry conditions, localized elevated fire weather conditions appear probable. However, the limited extent of the threat and limited fuel status (ERC values near to below the 50th percentile) preclude highlights at this time. ..Moore.. 12/30/2023 ...Please see www.spc.noaa.gov/fire for graphic product...
