SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0228 AM CST Thu Jan 29 2026 Valid 311200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are unlikely Saturday. ...Synopsis... A highly amplified flow pattern will persist across the CONUS Saturday with a strong upper trough intensifying over the Southeast and western Atlantic. As the trough matures, a deep surface low will develop and lift northeastward along the Atlantic seaboard. An associated cold front will move out to sea with offshore flow in its wake as ridging and high pressure build across the western and central US. This will suppress substantial inland moisture return and reinforce a cold Arctic air mass over much of the continent. In turn, thunderstorms are unlikely over the CONUS, outside of the offshore waters of far south FL and the Carolina Outer Banks. ..Lyons.. 01/29/2026 Read more

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1252 AM CST Thu Jan 29 2026 Valid 301200Z - 311200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms appear unlikely Friday through Friday night. ...Synopsis... Large-scale ridging will generally be maintained across the western US as a broad, multi-component upper trough over the eastern half of the US is forecast to rapidly consolidate and strengthen Friday into early Saturday. A prominent shortwave impulse emanating from southern Canada will merge with several smaller perturbations over the southern MS Valley and Gulf Coast vicinity. The net result will be a large and intense positive tilt upper trough over the southeastern CONUS. This strong trough and 100+ kt mid-level flow will aide the development of an initially weak surface cyclone over the eastern Gulf and FL Peninsula. The low will rapidly deepen late Friday into early Saturday off the Atlantic coast as a cold front moves offshore. Ahead of the front, modest low-level moistening/destabilization is possible over parts of southern FL and the keys. However, this appears short lived and without more substantial ascent/destabilization, thunderstorms are unlikely. ..Lyons.. 01/29/2026 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1141 PM CST Wed Jan 28 2026 Valid 291200Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected today or tonight. ...Synopsis/Discussion... A convectively inactive scenario will persist across the CONUS with virtually nil thunderstorm potential. Longwave trough will persist east of the Rockies with associated cold/continental trajectories prevalent, with upper ridging over the Rockies and Intermountain West. Multiple shortwave troughs will influence the Pacific Northwest, but the potential for lighting-producing convection is likely to remain low even in near-coastal areas given the forecast thermodynamic profiles. ..Guyer/Thornton.. 01/29/2026 Read more

Fire weather concerns will be negligible on D2/Friday. A surface high will build in across the central US, further reinforcing the cold arctic air southward into the Plains and Missouri/Mississippi River Valleys. This pattern will favor generally light winds and with the very cold air mass will keep fire concerns low across the CONUS. ..Thornton.. 01/29/2026 ...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 1142 PM CST Wed Jan 28 2026 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... ...Synopsis... A shortwave trough will move across the central Rockies today, with a surface low developing across eastern Colorado. A mostly dry cold front will shift southward across the Southern Plains. Some period of increasing surface wind (southerly becoming west and northwest as the front passes) will be possible. Temperatures will remain cool, with another reinforcing shot of cold arctic air behind the front. The continued cool conditions in addition to snow pack and generally wet fuels should keep fire concerns low. Across portions of the southern Florida Peninsula, dry conditions will continue. Afternoon relative humidity reductions to around 20-25 percent will be likely. Winds are expected to be mostly light, which will keep fire concerns low. ..Thornton.. 01/29/2026 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
