Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0258 AM CST Tue Dec 26 2023 Valid 291200Z - 031200Z ...DISCUSSION... A series of reinforcing upper shortwave troughs will maintain mean troughing over the eastern U.S. during the Day 4-8 period. Upper ridging across the western states will persist on Day 4/Fri before an upper trough moves inland along the Pacific coast. This system will shift east toward the southern High Plains on Day 6/Sun while merging with the mean upper trough across the east late in the forecast period. Prior cold frontal passages deep into the Gulf of Mexico, and surface high pressure over the Plains, will preclude thunderstorm activity across most of the CONUS. However, by the end of the period, some modest moisture return may impinge on the western/central Gulf coast as the ejecting upper shortwave trough over the southern High Plains merges with the eastern trough over the Lower MS Valley/Southeast. However, quality moisture return appears unlikely, and severe thunderstorm potential will remain low. Read more

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

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
