SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0125 PM CST Wed Jan 01 2025 Valid 031200Z - 041200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Little if any thunderstorms are expected on Friday. ...Synopsis... An upper low will deepen over southern Quebec as an upper trough amplifies across the eastern CONUS. Heights will rise along the central Gulf Coast south of a strong upper jet, with a cold front pushing south across the western Gulf of Mexico. A strong surface ridge will extend from SK/MB southward across the Plains and into the Southeast, maintaining stable conditions. Potential thunderstorms off the LA Coast are expected to wane during the day. To the west, a progressive, amplified shortwave trough will move east across the northwestern states, with a surface low weakening late off the WA/OR Coasts. A few low-topped thunderstorms are most likely over the Pacific Ocean, but a low-probability flash or two cannot be ruled out over far western WA and OR as the rapid cooling aloft occurs. ..Jewell.. 01/01/2025 Read more

SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1102 AM CST Wed Jan 01 2025 Valid 021200Z - 031200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Thursday. ...Synopsis... Moderate to strong northwest flow aloft will exist across the CONUS on Thursday, extending from an upper ridge over the West Coast to the East Coast. As this western ridge shifts eastward, a tightening midlevel thermal gradient will develop over the Plains, with a minor trough amplification from the Mid/Lower MS Valley into the Southeast. At the surface, high pressure will maintain a stable air mass over land, with any appreciable instability over the western Gulf of Mexico. As the upper wave develops, lift will increase across portions of the northern Gulf Coast after 00Z, with precipitation developing. It still appears that any weak elevated instability may be insufficient for thunderstorms over land, but a isolated flash cannot be ruled out near the TX/LA Coasts. ..Jewell.. 01/01/2025 Read more
