SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0154 AM CST Thu Feb 06 2025 Valid 061200Z - 071200Z ...Synopsis... Zonal, mid-level flow is forecast to continue across the central and western US today and tonight. Embedded within the westerly flow, several weak perturbations will cross the Rockies enhancing a lee trough over the High Plains. ...Southwest and Southern High Plains... Dry and breezy conditions are again expected across parts of eastern AZ and NM today as strong westerly flow continues over the Rockies. Several embedded mid-level perturbations will help strengthen lee troughing, and the resulting west/southwesterly surface winds to 15-25 mph. The strong downslope winds, along with warm temperatures and days of low humidity will support afternoon RH values of 10-15%. Given the favorable overlap of strong winds, low humidity and ongoing drought, widespread elevated fire-weather conditions are likely. A few hours of locally critical fire-weather conditions also appear possible within areas of stronger terrain-enhanced wind gusts. However, confidence in widespread critical conditions is relatively low. ..Lyons.. 02/06/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1257 AM CST Thu Feb 06 2025 Valid 071200Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Showers and a few lightning flashes will be possible Friday, particularly across the high terrain of northern Utah and vicinity. ...Discussion... Within the background quasi-zonal flow aloft across the U.S., a short-wave trough is forecast to shift eastward out of the northwestern U.S. across the Great Basin and northern Intermountain region. Quasigeostrophic ascent associated with this feature will support scattered showers, with a few lightning flashes possible -- particularly across favored high-terrain areas of northern Utah and surrounding areas. The advance of the aforementioned upper system will support eastward progression of a weak/associated surface low. Late in the period, the low should emerge into the northern Plains. Meanwhile, farther south, a persistent baroclinic zone will remain draped from Oklahoma to the Carolinas through the period. While isolated showers will be possible in the vicinity of this front, weak instability should preclude thunderstorm potential. ..Goss.. 02/06/2025 Read more
