Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0203 AM CST Sun Jan 26 2025 Valid 281200Z - 291200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... No thunderstorms are forecast over the continental U.S. on Tuesday or Tuesday night. ...DISCUSSION... A mid-level ridge is forecast over the southern Plains on Tuesday, as an upper-level low moves southward across the Desert Southwest. Mid-level flow will become more southwesterly over western parts of the southern Plains, as low-level moisture advection occurs across the southern part of Texas. Although showers could develop late in the period near the northern edge of the stronger flow over northeast Texas and southeastern Oklahoma, instability should be too weak to support thunderstorm development. Elsewhere across the continental U.S., thunderstorms are not expected Tuesday and Tuesday night. ..Broyles.. 01/26/2025 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0120 AM CST Sun Jan 26 2025 Valid 271200Z - 281200Z ...Synopsis... Portions of eastern Arizona and far west/southwestern New Mexico will continue to see elevated fire weather concerns through Monday afternoon. The upper low currently deepening off the central CA coast is forecast to reach peak intensity over the next 24 hours over southern CA before gradually shifting east into the lower CO River Valley by late Monday. This eastward shift will be influenced by the ejection of a mid-level jet max on the southeastern fringe of the upper low into northwest Mexico, which will promote surface pressure falls across AZ/NM under the left-exit region. In response, southerly low-level winds are forecast to increase to around 15 mph, which when coupled with an antecedent dry air mass (forecast RH minimums between 10-20%), should promote elevated fire weather conditions. Surface winds are expected to be strongest in proximity to the surface trough, which most solutions agree will likely reside along, if not just east of, the AZ/NM border. Localized critical conditions appear possible within the higher terrain of the Gila region in southwest NM, but the potential for widespread/sustained critical conditions appears limited. Fuels across this area continue to cure after several days of anomalously low dewpoints with ERCs approaching the 90th percentile in some areas, and should support the fire weather concern. ..Moore.. 01/26/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1239 AM CST Sun Jan 26 2025 Valid 261200Z - 271200Z ...Synopsis... Fire weather concerns will continue across parts of eastern/southeastern Arizona and into far western/southwestern New Mexico for today. 06 UTC surface observations continue to sample a very dry air mass across the southwestern states with dewpoints between -15 to 5 F and nocturnal RH values in the single digits to low teens across much of southern to central AZ. Negligible moisture return into the region will promote another day of widespread 10-15% RH minimums. Aloft, an increasingly pronounced upper low along the central CA coast will gradually shift southward over the next 24 hours, maintaining a broad swath of strong southwesterly winds over AZ. Surface pressure falls will be concentrated across southern CA today resulting in weaker pressure gradient winds - generally around 15 mph - compared to yesterday/Saturday; however, the deep dry layer near the surface will facilitate downward mixing of stronger mid-level winds, resulting in gusts upwards of 25-35 mph by early afternoon. Recent guidance continues to suggest the windiest conditions will reside on the northern slopes of the Mogollon Rim as well as across much of southeast AZ into far southwest NM. Consequently, confidence in sustained elevated fire weather conditions remains highest across these regions where fuels remain receptive amid persistent dry/breezy conditions. ..Moore.. 01/26/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
