SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1107 AM CST Mon Dec 30 2024 Valid 311200Z - 011200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible from the Outer Banks into southern New England late Tuesday into early Wednesday. Severe thunderstorms are not expected. ...Synopsis... An upper trough will pivot northeast from the Midwest toward the Mid-Atlantic/Northeast on Tuesday. A prior cold frontal passage across this region will result in limited boundary-layer moisture despite increasing low-level south/southeasterly flow ahead of a surface low. The exception will be along the immediate coast from near the Outer Banks to southern New England Tuesday night into early Wednesday. Surface-based instability will remain limited, but weak elevated instability amid increasing large-scale ascent and cooling aloft may be sufficient for isolated thunderstorms from the Outer Banks (Tuesday afternoon) into southern New England (mainly after 00z). Severe storms are not expected. ..Leitman.. 12/30/2024
