Thunderstorms are not expected on Wednesday. ...Synopsis... A deep mid/upper-level trough will remain in place over most of the CONUS on Wednesday. Anomalously cold conditions are expected from the Great Plains to the Eastern Seaboard, in the wake of a strong cold front. Weak MUCAPE may persist across far south FL and the Keys very early in the forecast period, but deep convection appears unlikely due to warm temperatures

Thunderstorms are not forecast on Thursday. ...Synopsis... A cool and stable pattern will persist on Thursday across the CONUS with an expansive upper trough over much of the central states and into the Great Lakes. This trough may amplify as it becomes more progressive and moves into the MS Valley by 12Z Friday. A strongly cyclonic speed max will exist along the northern Gulf Coast, with cooling aloft to

Thunderstorms are not expected on Wednesday. ...Synopsis... A large upper trough will remain over all but the westernmost CONUS on Wednesday, with a leading trough exiting the East Coast early in the day. At that time, high pressure will firmly be in place over the East, with strong north winds over the Gulf of Mexico and western Atlantic. A weak surface low may develop along the front over the

The risk for thunderstorms appears negligible across the U.S. today through tonight. ...Discussion... Ridging to the north of the blocking mid-level high centered over the mid-latitude eastern Pacific is rebuilding, as an initially suppressing short wave perturbation progresses inland across British Columbia. The latter feature is forecast to dig through the northern U.S. Rockies and adjacent Great Plains by 12Z Wednesday, reinforcing large-scale troughing now encompassing much of central

Isolated thunderstorms are possible this morning into early afternoon across parts of coastal Oregon and northern California. ...Coastal OR/northern CA... A potent mid to upper-level shortwave trough will move ashore the northern CA/OR coast and continue northeastward into the southern Canadian Rockies/northern Rockies vicinity through late tonight. Weak thunderstorm activity embedded within a warm-air advection rain shield will continue moving into the coastal range mountains this morning before
SPC Dec 21, 2024 Day 4-8 Severe Weather Outlook
Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0322 AM CST Sat Dec 21 2024 Valid 241200Z - 291200Z ...DISCUSSION... A more active southern-stream pattern is expected next week with several lower latitude troughs crossing the southern tier, along with some northward increase in low-level moisture across parts of Texas to the Lower Mississippi Valley and Gulf Coast. On Tuesday/Day 4, one such shortwave trough should influence increasing thunderstorm potential across south-central to east/southeast Texas. Some severe risk could materialize Tuesday, but it appears that overall buoyancy will be weak with the severe potential currently

Isolated thunderstorms are possible along the northern California coast early morning Saturday. ...Northern CA coast... An amplified upper trough will move northeast and approach the Pacific Northwest coast through 12Z Saturday. This will yield a pronounced low-level warm conveyor to overspread the adjacent offshore waters. This forcing for ascent in conjunction with an ample buoyancy plume has supported scattered to widespread thunderstorms around 500-600 miles offshore. This buoyancy
