Overall the forecast is on track this evening with a tight pressure gradient across the peninsula and the Atlantic waters in the wake of last nigheights front. Expansive high pressure across the mid section of the country will spill colder air into the southeast and Florida into mid week as another reinforcing mid level wave brings colder air by tomorrow night. For tonigheights forecast, expect low temps to range from the mid to upper 30s NW of I-4 to the 40s central and 50s from Ft Pierce south along the coast. Another subtle low/trough feature offshore will move south and increase the gradient near the coast and over the Atlantic overnight with lighter winds to 5-10 mph where the temps are expected to get the coldest across portions of Lake and interior Volusia counties. Min wind chills will drop into the 30s across the Volusia/northern Brevard and across the interior all the way south to Okeechobee county making for a cold morning for those heading off to work and school Tuesday morning. Low level winds should back some overnight to the NW/NNW and keep any late night shower activity just offshore the Treasure Coast so removed low Probability of Precipitation for the south coastal areas later tonight.
