SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1233 AM CST Sat Nov 30 2024 Valid 011200Z - 021200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Sunday. ...Synopsis... A large upper-level low centered over Ontario/Quebec provinces will persist through Sunday, with an expansive area of cyclonic flow across much of the central and eastern CONUS and a ridge over the western states. Surface high pressure from the Plains states into southeast U.S. will reinforce generally dry/stable conditions. With the exception of portions of deep South Texas, appreciable low-level moisture/instability will remain offshore Sunday and Sunday night. A sporadic lightning strike will be possible in association with lake-effect snow bands in the lee of Lakes Ontario and Erie, but overall coverage should remain limited. ..Bunting.. 11/30/2024 Read more

Ridging will continue to build across the West while persistent toughing remains across the central/eastern CONUS. This will result in localized offshore flow across parts of Southern CA, but in general, quiet fire-weather conditions are expected to prevail across the CONUS on Sunday. ..Karstens.. 11/30/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Quiet fire-weather conditions are expected today, as most areas of the CONUS remain under the influence of an upper-level trough positioned over the eastern CONUS. An upper-level ridge is continuing to build across the West, with weak high pressure at the surface. This will result in offshore flow across parts of Southern CA, though this threat appears too localized to introduce any highlights at this time. ..Karstens.. 11/30/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1123 PM CST Fri Nov 29 2024 Valid 301200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast for today. ...Synopsis... Much of the CONUS will remain under the western periphery of a broad mid-level trough, which will reinforce surface high pressure and associated cool surface conditions. Static stability over the CONUS will limit organized thunderstorm potential. A couple of lightning flashes cannot be ruled out over portions of Lakes Erie, Ontario, and immediate adjacent shorelines within lake effect snow bands. However, the sparse coverage of flashes suggests that thunderstorm highlights are unwarranted this outlook. ..Squitieri/Karstens.. 11/30/2024 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0613 PM CST Fri Nov 29 2024 Valid 300100Z - 301200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...Synopsis... Surface high pressure with associated colder and dry air, in tandem with nocturnal cooling, will promote widespread static stability across the CONUS, reducing the risk for thunderstorms through the remainder of the period. A lightning flash may occur with low-topped convective snow bands along the Lakes Erie and Ontario shorelines. A couple of lightning flashes also remain possible over the central FL peninsula ahead of a surface cold front. However, the potential coverage of thunderstorms in these areas appears low enough to warrant the removal of thunder probabilities this outlook. ..Squitieri.. 11/30/2024 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0345 PM CST Fri Nov 29 2024 Valid 011200Z - 071200Z Fire-weather concerns should generally remain low throughout the extended forecast period, as a cool and/or moist air mass encompasses much of the CONUS. The one exception will be across portions of the Florida Peninsula on Days 4-5/Monday-Tuesday. During this timeframe, a broad large-scale trough over the eastern half of the CONUS will progress eastward into the western Atlantic waters, while an upstream surface high shifts from the northern Plains into the Southeast. This will promote breezy northerly surface winds down the Florida Peninsula, where a relatively warm/dry antecedent air mass will be in place. Given a lack of rainfall over the last couple weeks and at least modestly receptive fuels, elevated fire-weather conditions will be possible. However, confidence in the development of critical conditions is too low to add Critical probabilities at this time. ..Weinman.. 11/29/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
