SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0153 AM CST Tue Dec 26 2023 Valid 281200Z - 291200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the Lower 48 states on Thursday. ...Synopsis... A large upper cyclone and attendant trough will persist across the eastern U.S. on Thursday, pivoting slowly east from the MS Valley toward the Appalachians. Meanwhile, an upper ridge will envelop much of the western half of the CONUS. A cold front moving deep into the Gulf of Mexico and well offshore of the Atlantic coast, will leave a dearth of boundary-layer moisture across most of the U.S. As a result, thunderstorms are not expected on Thursday. ..Leitman.. 12/26/2023 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0145 AM CST Tue Dec 26 2023 Valid 271200Z - 281200Z ...NO CRITICAL AREAS... ...Synopsis... On Wednesday, a closed upper low will drift slowly east across the Midwest. By this time, the surface low will weaken enough that stronger winds mostly should subside. Fuels should remain moist across most of the CONUS on Wednesday with cool conditions across most of the western/central CONUS and mild, but moist conditions along the East Coast. Therefore, fire weather concerns will remain minimal. ..Bentley.. 12/26/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Some breezy conditions are possible today across the central/northern Plains as the surface pressure gradient slowly relaxes. However, cool conditions dominate across most of the CONUS. In addition, most of the CONUS has seen wetting rain within the last few days. Therefore, fire weather concerns are minimal today. ..Bentley.. 12/26/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1229 AM CST Tue Dec 26 2023 Valid 271200Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Wednesday. ...Synopsis... A large upper cyclone will be centered over the Mid-MS Valley on Wednesday. This system and associated upper trough will move only modestly eastward through the period. Deep-layer southwesterly flow ahead of the upper low/trough will be maintained over the eastern third of the CONUS. At the surface, low pressure off the SC coast will lift north/northeast. The center of the low will pass near or just offshore from the NC Outer Banks. Showers will be ongoing across the Mid-Atlantic Wednesday morning. While generally poor lower-level lapse rates and little heating will limited instability, some modest midlevel lapse rates will support modest elevated instability, and isolated thunderstorms are possible across coastal NC. A surface cold front will move offshore the Mid-Atlantic during the evening/overnight hours. Severe thunderstorms are not expected. Across the West, a weak upper shortwave trough will quickly move across the Pacific Northwest. A few lightning flashes are possible offshore from the northern CA/OR/WA coasts, but overall chances for inland lightning appear lower than previously indicated given meager elevated instability. ..Leitman.. 12/26/2023 Read more
