Fri night-Sat night...As convection starts to wind down Fri evening
across northern Lake and northern Volusia counties, a cold front
across east central FL will slowly start to move to the north with
no significant rainfall for the rest of the night. On Sat, as the
front moves further north, moisture will also push north and only
Lake, Seminole and Volusia counties will see shower and lightning
storms, mainly in the afternoon. Saturday highs will reach the
mid 80s towards the north and lower 90s towards Osceola southward
to Okeechobee county and Treasure Coast. Min temperatures on Fri
night will be in the lower-mid 60s.

Sun-Thu (previous discussion modified)...Absent of any real synoptic
push, the front relents to parallel upper flow and remains across
north-central Florida through mid-week, before the models hint at it
making any move. The front will provide an alley of moisture to
plume and concentrate from the Gulf of Mexico setting up a multi-day
period of generous rain. Frontal location will adjust slightly south
across the heart of the peninsula to offer several rounds of
potentially heavy rainfall further supported by a series of minor
waves along the boundary. Prolonged rain on tap for all locations,
but most likely for the area north of Orlando and the Cape on
Sunday, then overspreading much of east central Florida though mid-
week. The front is depicted by GFS and ECMWF to push south of the
local area late Wed, possibly reducing showers coverage from north
to south on Thu. Max temperatures on Sunday will realize lower 80s
north forecast area to lower 90s south forecast area. Then,
increased cloud cover along with likely showers/storms will keep max
temperatures dialed-back into the 70s to lower 80s. Min temperatures
continue in the 60s.
