Today-Tonight...High pressure prevails over the local area today.
A cold start for many, with wind chills already in the lower to mid- 40s for much of the area as of around 3AM. Forecast peak wind chills this morning are as low as the upper 30s north of I-4.
Temperatures will begin to warm after sunrise. However, northerly winds will help to keep temperatures below normal this afternoon.

Increasing mid-level moisture will lead to increasing clouds into the afternoon hours. There is a High Risk of rip currents at area beaches.

Tonight, northerly winds will persist, but slacken to around 5mph.
Increased cloud cover will limit radiational cooling. While overnight lows are still forecast to fall below normal, they won't be quite as cold as early this morning, remaining in the upper 40s to lower 50s for most areas. Locations north of I-4 will continue to see the possibility of lows in the lower 40s.

Thursday-Friday...High pressure lingers over the Deep South through Friday, though it will weaken through the period. Dry conditions continue to prevail over land areas. The pressure gradient will continue to slacken, leading to light winds. Wind directions may be variable at times, but generally northerly flow looks to persist.
Clearing skies into Friday will do little to improve the continued below normal temperatures. Highs will struggle to reach 70 degrees for all but the southern Treasure Coast. Overnight lows will once again dip Thursday night into Friday morning, with radiational cooling making it the coldest night of the week. Lows are forecast in the lower to mid-40s for much of east central Florida, with wind chills in the upper 30s to lower 40s. Temperatures warm slightly into Friday night with additional cloud cover, remaining in the upper 40s to lower 50s.

Saturday-Sunday...The pattern begins to become more active this weekend, as a warm front lifts through east central Florida ahead of a low pressure system drifting through the Southeast US. This system is forecast to drag a cold front through the local area on Sunday.
Until then, breezy southerly winds developing Saturday will advect in higher moisture to the peninsula, with PWATs climbing to between 1.3-1.5". PoPs will increase accordingly, first along and north of the I-4 corridor, then spreading southward into Saturday night. PoPs 30-60% through this period.
Rain chances will continue Sunday, as the front moves through the area, with PoPs lingering at 20-30% into Sunday night. Have not included a mention for any lightning storms, as CAPE is forecast to be very minimal at this time.

Southerly winds will help to bring a dramatic temperature swing, leading to highs above normal and a break from several weeks of colder temperatures. Highs Saturday afternoon are forecast in the mid to upper 70s to lower 80s area-wide. By Sunday, the approaching front will produce highs in the 70s for most of the area and lower 80s for the Treasure Coast and Okeechobee County.
Overnight lows in the lower to mid-60s Saturday night will fall into the upper 40s to lower to mid-50s behind the front Sunday night.

Next Week...An active pattern is forecast to continue into early next week. Models continue to disagree on the exact setup.
However, the bottom line appears to be that shower chances will continue, though the amount of showers is in question. Onshore flow looks to develop, producing breezy conditions along the coast.
Temperatures are forecast to remain cool, but nearer to normal than the previous few weeks.
