Area Forecast Discussion
National Weather Service Jacksonville FL
822am EDT Monday September 23 2019

Most locations this morning fell into the 60s, with a couple locations falling into the upper 50s this morning. A couple locations also saw some patchy fog this morning, but that was quickly scattering out. Stratocu was moving across the regional Atlantic waters and into the coastal locations, with mainly clear skies across the rest of the region. High pressure will be in control of the weather today, providing a light north to northeasterly flow aloft and east to east northeast flow at the surface. Very dry conditions above the surface will keep precipitation chances out of the forecast once again. Highs across the interior will be in the upper 80s to lower 90s, with mid 80s at the beaches.
