Short term (Today and Wednesday):

Expansive upper level ridging over the southern Gulf of Mexico will continue to erode along it's northern periphery as compact closed low shifts eastward across the southern Plains today. At the surface, a weak frontal boundary will be creeping down the peninsula today before becoming stationary just north of the area. With the surface ridge having retreated into the western Atlantic, weak southerly steering flow will be present across South Florida. This will help to maintain ample enough boundary layer moisture to support a few showers this afternoon, mainly across the interior and Lake Okeechobee region before refocusing across the northern Atlantic.

On Wednesday as the upper low prepares to move off the southeastern coastline, a surface low is forecast to develop along the stationary front, allowing the boundary to gain enough momentum to finally make it's push southward across the area as a weak cold front. Guidance hasn't budged with it's lack of convective excitement, thus have kept slight chance of showers across Palm Beach and the northern Atlantic waters as flow increases and veers more SW to W ahead of the front.

Warm temperatures stick around just a few more days with mid 80s to upper 80s each afternoon.

Long term (Thursday through Monday):

Models depict a sharp mid level trough pushing into the eastern seaboard Wednesday night into Thursday, with an associated surface front moving southward across the peninsula. None of the long range models indicate a significant impact from this FROPA other than a slight increase in showers, and a brief cooling trend establishes with a cooler, drier air mass advecting into SoFlo. However, temps rebound relatively fast on Thursday, with morning lows diving into the mid upper 50s to low 60s in the morning, then back to around 80 in the afternoon.

The drier air mass should result in little to no significant rain chances through Friday evening when another mid level short wave trough moves into the area. An associated low develops over the northern Gulf waters, which brings increasing chances of showers and a slight chance of thunderstorms over SoFlo on Saturday and into Sunday morning. Highest POPs seem to reside over the northern half of the CWA with Palm Beach county in the 60 to 70 percent range. By Sunday afternoon, high pressure is expected to begin establishing across the area in the wake of the low and bring dry conditions once again early next week.
