Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1126 AM CST Tue Jan 03 2017 Valid 041200Z - 051200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Wednesday through Wednesday night. ...Synopsis... The southern extent of a cold front, that will have moved off the rest of the Eastern Seaboard today, is forecast to advance equatorward through central and south Florida Wednesday. Meanwhile, a large surface anticyclone (located beneath confluent flow aloft) is expected to expand east from the Great Plains to the Mid Atlantic and Gulf Coast States. An arctic front leading this intrusion of cold air should reach north Florida Wednesday evening. Stable conditions across the contiguous U.S. are expected to preclude thunderstorm development this forecast period. ...East-central to south Florida... Initially, residual low-level moisture will be present south of the leading cold front across central and south Florida. However, the combination of 1) veering low-level winds resulting in a drying trend in the boundary layer and a reduction of frontal convergence, and 2) poor midlevel lapse rates due to warmer temperatures aloft as compared to today should inhibit the development of deep moist convection. ..Peters.. 01/03/2017Read more
