Area Forecast Discussion

1041am EST Sat Jan 23 2021

Light northerly breezes prevail across the Florida Keys. The surface gradient has all but collapsed, although surface pressures are 1019-1020 across South Florida and the Keys. Thus, it appears the baggy ridge axis lingers across the area. Temperatures have rebounded into the lower 70s, with some locations falling into the mid 50s earlier this morning. Skies are mostly sunny and the KBYX radar is echo free. The forecast calls for highs in the mid to upper 70s, a tick or two higher than yesterday. Rain chances are nil.
