Please see the previous discussion for additional details. ..Barnes.. 12/20/2025 .PREV DISCUSSION... /ISSUED 0110 AM CST Sat Dec 20 2025/ ...Synopsis... A mid-level trough will gradually amplify while traversing the Great Lakes today, encouraging the southward translation of a weakening surface low across the southern Plains. As a result, dry downslope flow is expected across portions of eastern New Mexico into western Texas ahead of a southward-sagging surface cold front today. During the afternoon, with boundary-layer mixing, RH will drop below 20 percent over several locales as sustained westerly surface winds exceeding 15 mph becomes abundant, warranting the continuation of Elevated highlights. Guidance consensus continues to depict overlapping 20+ mph sustained westerly surface winds amid 15 percent RH along portions of the New Mexico/Texas border, where Critical highlights have been maintained. ...Please see www.spc.noaa.gov/fire for graphic product...
