Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0347 AM CST Sun Dec 29 2024 Valid 011200Z - 061200Z ...DISCUSSION... A broad/expansive upper-level trough will persist over much of the eastern U.S. during the upcoming week, while a ridge of high pressure will extend over the western portion of the CONUS. A series of surface high-pressure systems will result in generally dry/stable conditions and minimal to no chance for thunderstorms through Friday/Day 6. Towards Saturday/Sunday (Days 7 and 8), guidance is varied but does suggest some increase in thunderstorm potential over the south-central U.S. as an impulse over the western U.S. moves east of the Rockies. Uncertainty is high at this relatively extended range on the timing and degree of amplification of this feature, and therefore the overall potential for thunderstorms remains low with this outlook.

SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0212 AM CST Sun Dec 29 2024 Valid 311200Z - 011200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Tuesday. ...Synopsis... A compact, negatively-tilted upper trough will lift northeast across the Ohio Valley and northeast U.S. Tuesday, as a developing coastal low near the Mid-Atlantic coast moves into southern New England by 12z Wednesday. Strong ascent will overspread this area in advance of a cold front, and an isolated lightning strike or two will be possible within an area of developing precipitation during the afternoon from coastal NC across the Delmarva region. With very minimal MUCAPE expected, coverage should be too sparse for introduction of a general thunderstorm area. Elsewhere, thunderstorms chances will be negligible in the presence of a generally dry and stable air mass over much of the CONUS. ..Bunting.. 12/29/2024 Read more
