Area Forecast Discussion National Weather Service Miami FL 337 PM EDT Fri Jun 30 2017 .DISCUSSION... THIS AFTERNOON AND TONIGHT: A little stronger southeasterly flow today has already pushed a more diffuse Atlantic seabreeze well inland this afternoon with scattered convection accompanying it. While slower to develop, the Gulf breeze has also managed to make it inland to the US41/I75 corridor. SAL layer is evident on satellite this afternoon across the region and NW Caribbean. This has been keeping convective coverage down so far, though expect a little bit of an upswing with the seabreeze merger near the Gulf coast later this afternoon. Other outflow boundary collisions will keep activity going into the late evening hours over the interior and Gulf coast. With the stronger SE flow and adequate low level moisture, Atlantic showers will make a comeback this evening and overnight. This activity will brush the east coast occasionally with the remainder of the region staying dry. THIS WEEKEND THROUGH FOURTH OF JULY HOLIDAY: Weather for the long holiday weekend will be dominated by the western Atlantic ridge, both at the surface and aloft, with its axis extending across the Florida peninsula. East-southeast flow prevails through the period, with a more dominant Atlantic seabreeze pushing quickly across the southern peninsula each afternoon. Remnant drier air from the aforementioned SAL layer may continue to suppress convection again on Saturday, with coverage closer to climo Sunday through Tuesday. Showers and thunderstorms will be focused over the interior and Gulf Coast during the afternoon/evening, with nighttime and morning isolated to widely scattered showers/storms over the Atlantic waters occasionally reaching into portions of the east coast. Temperatures will be near to slightly above normal, with highs in the 90s for most areas and lows generally in the 70s. REMAINDER OF NEXT WEEK: The western Atlantic ridge axis remains to our north through the remainder of next week, resulting in a fairly typical summertime easterly flow pattern across the region. The sea breezes will develop during the afternoon hours, with scattered showers and thunderstorms favored over the interior and Gulf Coast as the Atlantic seabreeze moves inland quicker. Nighttime/early morning activity will favor over the Atlantic waters and east coast. With a slight weakening in the upper-level ridging, daytime activity may also be prevalent along the east coast as well. Temperatures will be near to slightly above normal during the long term period. && .MARINE...Generally good boating conditions are expected across South Florida into early next week under light east-southeasterly flow and seas generally 2 feet or less. Isolated showers and thunderstorms are expected over the open waters particularly in the overnight and morning hours, with more scattered coverage along the Gulf coast in the late afternoon and evening as activity pushes off the mainland. Locally erratic winds along with lightning will be possible in and around thunderstorms. && .AVIATION...Convection is forecast for this afternoon, mainly well west of the Atlantic coast TAF sites, other than PBI. The easterly flow across the area is forecast to keep the convection in the interior and over the Gulf coast through the early evening hours. While there is a slight chance for convection over the metro area, the certainty is too low for any mention at this time. KAPF will see increasing chances of VCTS and SHRA through the late afternoon and early evening. && .PRELIMINARY POINT TEMPS/POPS...
