A subtle mid-level short wave embedded within westerly zonal flow will move into the Southern Plains. An attendant but modest wind maxima aloft in addition to a deepening lee surface low across northwestern TX will maintain dry and breezy conditions for portions of the Southwest and Southern Plains Saturday. Elevated fire weather conditions including west to southwest winds of up to 20 mph and relative humidity in the 10-15% range are still expected. The elevated fire weather threat was nudged northward into south central CO based on latest model guidance and overall persistent westerly flow aloft. Localized downslope enhanced winds of around 20 mph, relative humidity near 15% and dry fuels will increase fire spread potential. Farther west, an influx of subtropical Pacific moisture ahead of a more pronounced trough impinging upon the CA Coast will promote increasing cloud cover over the broader CO River Basin Saturday. Some precipitation is likely to develop late Saturday afternoon and evening, temporarily mitigating fire weather concerns amid an otherwise breezy day across the region. ..Williams.. 04/24/2026 .PREV DISCUSSION... /ISSUED 1257 AM CDT Fri Apr 24 2026/ ...Synopsis... A broad, large-scale upper level trough will be anchored near the international border over the central US through the weekend. To the east, the prevailing upper-level ridge will collapse on Day 2/Saturday as an approaching mid-level shortwave trough triggers widespread precipitation over the Midwest and Appalachians. This change is expected to provide some relief to the critically dry fuels over these regions. However, for areas bypassed by appreciable rainfall (especially east of the southern Appalachians), the fire risk posed by lingering drought conditions will persist. ...Southern Plains into portions of the Southwest... Zonal flow aloft will remain in place across the Southwest on Saturday, sustaining very breezy and dry conditions. Following several consecutive days of heightened fire weather, the fuel environment remains highly stressed, especially over northern extents of the drawn area. Westerly downslope winds of 15-20 mph will coincide with relative humidity values of 10-20% over receptive fuels, further aggravating the fire risk. Consequently, an Elevated area exists for Day 2/Saturday across much of New Mexico, southeast Arizona, and portions of west Texas where fuels are receptive. While the dryline is expected to surge farther east across southwest/central Texas, fuel conditions near and south/east of Midland appear to be less receptive overall. However, this event will work to dry fuels over this region and may promote future risk across this area. ...Please see www.spc.noaa.gov/fire for graphic product... $$
