SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0957 AM CST Sat Feb 19 2022 Valid 191630Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... An isolated thunderstorm or two is possible this afternoon along the coast of southeast Florida. ...FL... A surface cold front extends across central FL today, and will push southward and offshore after dark. Convergence along the boundary is weak, and surface winds ahead of the front have veered to northwesterly. Nevertheless, ample low-level moisture is present in the pre-frontal air mass, with pockets of daytime heating expected. This may result in an isolated thunderstorm or two along the immediate coastline in vicinity of Miami. This threat should diminish by early evening as the front moves through and diurnal cooling commences. Elsewhere, very isolated lightning flashes will be possible today along a band of shallow convective snow squalls moving through NY/PA. This threat will remain below 10% coverage. ..Hart.. 02/19/2022 Read more CHECK UPDATE ZOOM GRAPHIC
