SPC 1730Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1122 AM CST Wed Jan 15 2025 Valid 161200Z - 171200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Thursday. ...Discussion... An upper trough over the eastern U.S. will advance slowly eastward Thursday, while the next feature -- a short-wave trough over western Canada -- digs southeastward, moving into the northwestern/north-central U.S. overnight. At the surface, cold/dry/stable conditions will persist. A pronounced cold front, associated with the digging/western upper system, will likewise shift southeastward out of Canada, but preceding high pressure will preclude

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1015 AM CST Wed Jan 15 2025 Valid 151630Z - 161200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...Synopsis and Discussion... With weak instability in place this morning, isolated thunderstorms should continue for a few more hours along parts of the middle/upper TX Coast as an upper trough pivots southeastward over the southern Plains. This activity will remain elevated in nature, and severe thunderstorms are not expected. Across the rest of the CONUS, dry and/or stable conditions will preclude

SPC 1300Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0646 AM CST Wed Jan 15 2025 Valid 151300Z - 161200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...Coastal Texas... Scattered elevated convection is expected to continue across the coastal plain as warm/moist advection persists while a weak mid-level disturbance moves eastward over the western Gulf of Mexico. Deeper lightning-producing convection will focus over the open Gulf waters, but a few lightning flashes could occur near the coast. This potential is substantiated by the 12z observed sounding from Corpus

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 PM CST Tue Jan 14 2025 Valid 150100Z - 151200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected tonight. ...01z Update... Weak mid-level disturbance is ejecting across northeast Mexico toward deep south TX early this evening. This feature should encourage weak elevated convection along the cool side of an offshore coastal boundary tonight. 00z sounding from BRO exhibits a modestly steep 3-6km lapse rate (7 C/km), and while moist, MUCAPE is only 100 J/kg. Lapse rates will likely remain a bit too weak

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1010 AM CST Tue Jan 14 2025 Valid 141630Z - 151200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected through tonight. ...Synopsis and Discussion... Expansive surface high pressure will continue to dominate much of the CONUS through the period, with minimal thunderstorm potential. Weak low-level warm/moist advection is forecast to occur tonight across parts of deep south TX. While modest MUCAPE should eventually develop over this region, limited large-scale ascent suggests thunderstorm chances should remain low. ..Gleason/Thornton.. 01/14/2025 Read more
