On the backside of the expansive closed midlevel low over the central Plains, a belt of strong deep-layer west-northwesterly flow associated with the dry conveyor belt will overspread portions of the southern High Plains. From southeast NM into portions of West TX (particularly the Trans-Pecos), forecast soundings depict very dry air through the vertical profile, which coupled with surface temperatures in the 50s, will yield 10-15 percent afternoon RH. At the same time, downward momentum transport and a modest pressure gradient will favor 20+ mph sustained west-northwesterly surface winds (with gusts upwards of 30-40 mph). While the area did receive some precipitation in the last few days, freeze-cured grasses may still support locally elevated fire-weather conditions given 1 to 2 days of drying and the dry/breezy conditions. ..Weinman.. 12/25/2023 .PREV DISCUSSION... /ISSUED 1243 AM CST Mon Dec 25 2023/ ...Synopsis...

The only exception will be across portions of the Dakotas and western Nebraska where a deeply mixed boundary layer is likely and some stronger jet stream winds may mix to the surface. However, even within this region, fire-weather concerns will be quite low due to the below-freezing temperatures in the region. ...Please see www.spc.noaa.gov/fire for graphic product...
