SPC May 14, 2023 0600 UTC Day 2 Convective Outlook

LIVE MAP (ABOVE) ... SPC 0600Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1239 AM CDT Sun May 14 2023 Valid 151200Z - 161200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe-weather threat is forecast to remain generally low across the U.S. Monday. ...Discussion... A mid-level short-wave trough -- embedded within broader eastern U.S. troughing -- is expected to advance southeastward into/across the western Atlantic Monday. As this occurs, surface high pressure will continue to shift/expand southward across much of the country. A weakening surface cold front, at the leading edge of the advancing cooler/drier continental airmass, will suppress higher theta-e air gradually southward, with appreciable instability limited to areas from the southern Plains eastward, and the Ozarks/Ohio Valley region southward. Ahead of the front, where a more moist/unstable airmass will linger, showers and thunderstorms are expected through the period. However, relatively weak flow aloft suggests disorganized storms, and severe potential even with the stronger storms likely to remain limited. Showers and thunderstorms will also develop across a large portion of the West, with a noted diurnal peak during the afternoon and evening. Here too, little appreciable risk for severe weather is evident. ..Goss.. 05/14/2023 Read more CHECK UPDATE ZOOM GRAPHIC
