Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0227 AM CST Sun Nov 19 2017

Valid 211200Z - 221200Z


A few thunderstorms are expected over a portion of the Florida
Peninsula into south Georgia Tuesday, but no severe weather is


Tuesday`s synoptic pattern will remain dominated by a mean ridge
over the western states with a downstream trough in the east. The
southern-stream branch of the upper trough will amplify over the
western Gulf in wake of a lead shortwave trough forecast to move
through the FL Peninsula during the day. Surface response will be
reflected by evolving area of weak low pressure over the northeast
Gulf that will redevelop over the Gulf Stream during the evening in
association with the progression of the lead shortwave trough. A
quasi-stationary front should persist across the central FL
Peninsula. Numerous showers and a few thunderstorms are expected,
mainly over the northern half of FL into southern GA within weak
warm advection regime maximized in advance of the leading shortwave
trough. Activity should diminish over the by evening as this impulse
continues east of the Peninsula and into the Gulf Stream.
