UPDATE... No significant changes to the forecast with this mornings update. Just some minor tweaks to account for new hi-res model data. High pressure should begin to build in as the cold front exits the region, with quiet weather for the day and gradually clearing skies.

SHORT TERM... Today and Tuesday... A shortwave trough will move off the Atlantic Seaboard on Monday with quasi-zonal flow prevailing in its wake across the Eastern States. With slowly building heigheights aloft this will support surface high pressure as it migrates from the Southern Plains/Western Gulf towards the coastal Carolinas. Cool temperatures should prevail for today and tonight, with highs around 70 and lows dipping into the 40s for inland areas with 50s for the east coast metro areas and immediate Gulf Coast. Winds will turn more onshore by Tuesday allowing temperatures to moderate by a few degrees with highs in the lower to mid 70s. Mostly cloudy skies early this morning should clear out by afternoon with mostly sunny skies on Tuesday.

Long Term Wednesday Through Friday... High pressure centered across the FL peninsula and mid-level ridging anchored over the eastern Gulf will work in concert to keep dry and pleasant weather in place for the remainder of the week. The placement of South Florida within the SE periphery of the surface high will maintain gentle NE flow, which should gradually moderate temperatures back to near seasonable and slightly above.

Daytime highs will be in the 70s across South Florida for the start of the week and warm to the lower 80s by late week. Overnight lows should follow the same warming trend and climb back into the seasonable 60s.

Friday through Sunday
The surface high's axis then shifts into the western Atlantic late week into the weekend ahead of our next frontal system and veer the flow out of the SE to SW. Given the lack of moisture rebounds ahead of the boundary, models continue to indicate a FROPA with very little fanfare. Will continue to monitor trends between runs, but see no need at this time to deviate from guidance and reintroduce Probability of Precipitation into the forecast.

Marine Discussion
Benign marine conditions are expected over the next several days with no meaningful weather impacts anticipated.
