SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CST Wed Jan 28 2026 Valid 301200Z - 311200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms appear unlikely Friday. ...Synopsis... Mid-level flow over the US will continue to amplify as persistent eastern troughing is bolstered by the arrival of a northern stream shortwave from Canada and a deepening southern stream wave over the Gulf Coast. As these systems merge, a strong upper low is excepted to develop across the Southern US deepening a surface low over the eastern Gulf and western Atlantic into early Saturday. At the same time, strong ridging aloft will build over the West supporting increasingly strong northwesterly flow. This will allow a strong cold front and Arctic high pressure to move out of southern Canada reinforcing offshore flow over the lower 48. As such, inland moisture return and the potential for thunderstorms appears unlikely. ..Lyons.. 01/28/2026 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0140 AM CST Wed Jan 28 2026 Valid 291200Z - 301200Z ...NO CRITICAL AREAS... ...Synopsis... A shortwave trough will move across the central Rockies on D2/Thursday, 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 (first from the south 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. ..Thornton.. 01/28/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook

Fire weather concerns are expected to remain low today across the CONUS. A cool and dry air mass will remain in place, 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 mostly light winds will preclude the need to include any areas. ..Thornton.. 01/28/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

Thunderstorms are unlikely Thursday. ...Synopsis... Broad-scale troughing over the eastern US is forecast to continue Thursday as a shortwave perturbation moves out of the Rockies/southern Plains into the Southeast. This will allow a weak surface low to deepen over the lower MS Valley and Gulf Coast with a cold front moving through the southern Plains. A second stronger trough will move south out of Canada and deepen over the northern US as western ridging continues to build. This will intensify surface high pressure over the northern US as a reinforcing surge of Arctic air moves south. This will keep inland moisture return and thunderstorm chances minimal Thursday. ..Lyons.. 01/28/2026 Read more

Thunderstorms are not forecast for today. ...Synopsis... A relatively stable pattern will exist across the CONUS today, with high pressure affecting most areas. A deep upper low will remain over Ontario, with broad cyclonic flow aloft encompassing most of eastern Canada and the USA. With high pressure over land, offshore flow will keep appreciable low-level moisture well offshore from Cuba toward the Turks and Caicos. Precipitation will be possible in association with a shortwave trough moving across the Great Basin during the day and across the central and northern Rockies. However, little to no instability is forecast, and as such thunderstorms appear unlikely. ..Jewell.. 01/28/2026 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 PM CST Tue Jan 27 2026 Valid 280100Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms may occur through tonight across parts of northern California and coastal southwest Oregon. Severe thunderstorms are not forecast. ...Discussion... An upper trough will quickly move across northern CA and parts of the Pacific Northwest through tonight, with a weakening trend. Despite this, increasing lift, cooling aloft and a midlevel moist plume may support weak SBCAPE near the coast and elevated instability inland. The weak instability and minimal wind speeds below 700 mb should preclude any severe risk. Elsewhere, cool and stable conditions will prevail with an expansive upper trough east of the Rockies and high pressure. ..Jewell.. 01/28/2026 Read more
