A few non-severe thunderstorms are possible over parts of the Mid Atlantic during the day on Wednesday. ...Synopsis and Discussion... A deep upper low will fill slightly as it moves slowly east across the lower MS Valley, with a large area of cyclonic flow aloft over the Plains, MS Valley and Southeast. Relatively cool air will remain over much of the Plains with northerly winds extending into the western Gulf of Mexico, but a weak surface low will develop over NC in a zone of warm southeasterlies well ahead of the upper low. Extensive clouds and precipitation will limit destabilization as well as low-level lapse rates over NC and southern VA where MUCAPE may approach 500 J/kg. However, this will be sufficient to support scattered convection within the larger area of precipitation, by virtue of cool midlevel temperatures and mainly early in the day prior to drier air pushing in from the west as 850 mb winds veer. While forecast soundings over NC do show surface-based parcel potential, real boundary-layer buoyancy will be limited by the poor lapse rates/saturated profiles in a weak forcing regime. Therefore, despite veering winds with height and effective SRH values of 200-300 m2/s2, severe weather remains unlikely. ..Jewell.. 12/26/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
