Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0350 AM CST Tue Jan 27 2026 Valid 301200Z - 041200Z ...DISCUSSION... Severe weather potential in the extended forecast period is very low. Broad-scale eastern US troughing will strengthen this weekend as a clipper-style trough dives out of Canada an rapidly intensifies along the Eastern Seaboard. A surface low will develop over the eastern Gulf and rapidly deepen over the western Atlantic into early next week. Western US ridging and strong surface high pressure over the central US will keep substantial inland moisture return unlikely for the foreseeable future. Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0231 AM CST Tue Jan 27 2026 Valid 291200Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are unlikely Thursday. ...Synopsis... Broad-scale troughing will continue across the eastern half of the US as the primary upper trough moves off the East Coast into early Friday. At the same time several shortwave perturbations, emanating from southern Canada and the central Rockies respectively, will begin to converge and strengthen over the central US. In the wake of these systems, ridging will build over the West supporting continued strong northwesterly flow aloft. A cold front and Arctic high pressure will move south forcing offshore flow over the CONUS. This will again negate thunderstorm potential through the forecast period. ..Lyons.. 01/27/2026 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0150 AM CST Tue Jan 27 2026 Valid 281200Z - 291200Z ...NO CRITICAL AREAS... ...Synopsis... Fire weather concerns are expected to remain low on D2/Wednesday. A cool and dry air mass will remain in place across much of the CONUS, with extensive snow pack reaching from the Southern Plains into portions of the Northeast. Overall, the recent cold and wet pattern has improved status of fuels in many areas. Some dry conditions will continue across southern Florida but winds should be lighter, precluding the need to include any areas. ..Thornton.. 01/27/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0149 AM CST Tue Jan 27 2026 Valid 271200Z - 281200Z ...Synopsis... Dry post-frontal northwesterly flow across the southern Florida Peninsula will bring a period of Elevated fire concerns today. Relative humidity reductions to around 20-25% will overlap with sustained northwesterly flow around 10-15 mph. Fuels in this region are critically dry with ongoing drought conditions. The frontal passage did bring some rainfall across portions of the peninsula but little to no rainfall occurred across the far southern west coast, where the Elevated was maintained with this outlook. ..Thornton.. 01/27/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1224 AM CST Tue Jan 27 2026 Valid 281200Z - 291200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Wednesday. ...Synopsis... Upper troughing will continue over the eastern half of the CONUS Wednesday. Mid-level ridging over the Rockies and Great Basin will weaken slightly as a subtle mid-level perturbation moves inland from the eastern Pacific. However, ridging will quickly rebound with the amplified flow pattern favoring continued northwesterly flow aloft over the continent. This will reinforce a cold dry and stable air mass over much of the country. With no inland moisture return/destabilization, thunderstorm potential is negligible. ..Lyons.. 01/27/2026 Read more
