SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1148 PM CST Tue Dec 26 2023 Valid 271200Z - 281200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States through tonight. ...Synopsis... A large deep-layer cyclone centered over the mid MS Valley will slowly move east through tonight. An embedded mid-level disturbance will rotate through the outer orbit of the large-scale cyclone and move from the lower MS Valley to Long Island during the period. Weak buoyancy will primarily be relegated to the coastal areas of the Mid-Atlantic states, but it …

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0649 PM CST Tue Dec 26 2023 Valid 270100Z - 271200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms will not occur through tonight across the contiguous United States. ...Synopsis... Water-vapor imagery early this evening shows a large gyre centered over the lower MO Valley with weak mid-level ridges located along the East and West coasts. A moist/warm conveyor is located over the Carolinas northward into the upper OH Valley, where scant buoyancy was observed (i.e., Carolinas per 00z raob data) or forecast later tonight. This weak instabili…

SPC Day 3-8 Fire Weather Outlook Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0154 PM CST Tue Dec 26 2023 Valid 281200Z - 031200Z The potential for critical fire-weather conditions is low through the extended forecast period. On D4/Friday, a persistent midlevel low will gradually devolve into a positive-tilt trough over the eastern CONUS, while a related southwesterly jet streak overspreads the Southeast and Mid-Atlantic. A modest pressure gradient beneath the strong flow aloft will favor breezy/gusty surface winds across much of the Southeast into the southern Mid-Atlantic states, where marginal RH reductions are possible. However,…

Morning water vapor loops indicate a well-defined dry conveyor belt overspreading the southern High Plains, which is associated with an expansive midlevel cyclone over the central CONUS. Strong west-northwesterly flow aloft associated with this feature, coupled with a modest pressure gradient, will favor 20-25 mph sustained west-northwesterly surface winds (with gusts upwards of 35 mph) from southeast NM into the TX Trans-Pecos. Here, downslope warming/drying and boundary-layer mixing i…
