Severe Storms

SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0957 AM CST Wed Feb 19 2025 Valid 191630Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms appear unlikely through tonight. ...Synopsis... Water-vapor imagery this morning shows a mid- to upper-level low situated over the Upper Midwest with a large-scale trough east of the Rockies. Visible-satellite and lightning data show a southwest-northeast oriented linear cluster of thunderstorms over the central Gulf of America immediately ahead of a cold front pushing southeast. This thunderstorm activity will approach the west coast of the FL Peninsula this afternoon. 12 UTC initialized model guidance agrees with earlier model data in the notion of this activity weakening as it moves across the shelf waters and approaches the coast. While low/deep-layer flow appears conditionally favorable for organized convection along/very near the coast, the meager thermodynamic environment should limit the overall threat for damaging gusts. Elsewhere, cold/stable conditions will prevail east of the Rockies. Precipitation associated with non-thunderstorms is forecast across the Pacific Northwest moving into the northern Rockies and Great Basin. ..Smith/Lyons.. 02/19/2025 Read more

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0921 AM CST Wed Feb 19 2025 Valid 191700Z - 201200Z ...NO CRITICAL AREAS... Fire weather concerns remain limited today with no forecast changes required. See the previous discussion below for details. ..Moore.. 02/19/2025 .PREV DISCUSSION... /ISSUED 0148 AM CST Wed Feb 19 2025/ ...Synopsis... Fire weather concerns will remain low today across the CONUS. Height rises are expected across the western US and Rockies as an upper level high builds in. Across the Plains, an arctic air mass is in place with below normal temperatures and recent precipitation. Less precipitation fell across portions of western Texas where drier fuels remain, however, light winds and higher relative humidity is forecast. ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1300Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0642 AM CST Wed Feb 19 2025 Valid 191300Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms appear unlikely through tonight. ...Synopsis and Discussion... A semi-organized cluster of thunderstorms remains off the southeastern LA Coast this morning. This activity will track towards, and eventually reach, the west-central FL Peninsula later this afternoon. Nearly all guidance shows rapid weakening of the convective cluster as it moves over cooler shelf waters and approaches the FL Coast. The 12Z TBW sounding, along with various NAM/RAP forecast soundings this afternoon from Tampa Bay and vicinity, show rather poor low/mid-level lapse rates, which should hamper development of any more than weak instability inland. While low/deep-layer flow appears conditionally favorable for organized convection along/very near the coast, the meager thermodynamic environment should limit the overall threat for severe wind gusts. Still, an occasional strong gust may occur as the cluster weakens. ..Gleason/Dean.. 02/19/2025 Read more
