SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0148 AM CST Thu Feb 20 2025 Valid 201200Z - 211200Z ...Synopsis... An upper low will move across the southwest, bringing enhanced westerly flow aloft across portions of northern Arizona into northern/central New Mexico. This will result in increasing south to southwesterly surface winds with sustained winds around 15-20 mph overlapping relative humidity around 15-20 percent. A small Elevated delineation was maintained to cover the potential for drying of fine fuels amid windy/dry conditions. ..Thornton.. 02/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1220 AM CST Thu Feb 20 2025 Valid 211200Z - 221200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Friday. ...Synopsis... Surface high pressure will envelop much of the CONUS on Friday. A prior cold frontal passage into the Gulf, and subsequent intrusion of Arctic air over much of the country, will result in cold, dry and stable conditions. As such, thunderstorm potential is not expected on Friday. ..Leitman.. 02/20/2025 Read more

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1118 PM CST Wed Feb 19 2025 Valid 201200Z - 211200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for thunderstorms appears negligible across the U.S. today through tonight. ...Discussion... It appears that mid-level flow will remain generally progressive across North America through this period. This is likely to include the eastward progression of a significant trough, and deepening embedded low, across the Ohio Valley and middle/northern Atlantic Seaboard through offshore western Atlantic by 12Z Friday. Upstream, the southern portions of splitting inland advancing troughing is forecast to continue digging southeast of the Great Basin through southern Rockies and adjacent portions of the Great Plains, while broad ridging builds inland to north, across and east of the Canadian and northern U.S. Rockies. Beneath this regime, models indicate that strong surface cyclogenesis will proceed, well offshore of the middle through northern Atlantic Seaboard. However, expansive, seasonably cold surface ridging, now entrenched across most areas to the east of the Rockies, likely will be slow to modify. To the west of the Continental Divide, while seasonably more moderate, and stable, conditions continue to prevail across most areas, insolation beneath mid-level cooling and forcing for ascent overspreading the eastern Great Basin into Colorado Rockies may contribute to weak boundary-layer destabilization this afternoon. While it appears possible that thermodynamic profiles could become conducive to convection capable of producing lighting, the extent to which this may occur still seems too limited to support 10 percent or greater thunder probabilities. ..Kerr/Thornton.. 02/20/2025 Read more
