...Hot With Increasing Rain Chances This Week...
Today: A 40 % chance of showers and thunderstorms, mainly after 2pm. Mostly sunny and hot, with a high near 97. Heat index values as high as 105. West wind between 5 and 9 mph.
Tonight: A 30 % chance of showers and thunderstorms, mainly before 8pm. Partly cloudy, with a low around 73. West wind between 3 and 6 mph.
Scattered storms are expected to develop today mainly during the afternoon and evening as the sea breezes begin to develop and progress inland. Storm motion will be southeast around 10 mph. Periods of heavy rainfall, small hail and strong gusty winds will be the primary concerns in addition to lightning.
Daytime highs will rise into the mid 90s today and combined with increasing humidity heat index values will range from 100 to 108 degrees. Exercise extreme-caution when outdoors.
Today's pollen level: 4.2-Medium (on a scale of 1to12): predominate pollen: Grass and Oak.
Forecast Details: the mean layer 1000-700 mb ridge axis will gradually shift south-southeast from Alabama/Georgia to offshore of the Florida southeast coast through mid week while a shallow surface trough slowly edges down the southeast Atlantic seaboard. Increasingly moist west-southwest steering flow through the end of the week will not only increase rain chances for all zones, but also shift the focus for the sea breeze merger toward the eastern coast of the area. A band of high PWATs (2+ inches) across south Florida will shift northward today and models indicate this band of higher PWATs will linger across the area through Tuesday, then shift across the eastern half of the area Wednesday.
Above normal temperatures will continue over the area through mid week, but increasing moisture and resultant diurnal clouds will bring highs down slightly in the low/mid 90s. Lows in the low/mid 70s are still expected with patchy fog early in the morning, especially where recent heavy rainfall fell.
The main convective concerns will continue to be gusty winds and as PWATs increase periods of heavy rainfall in slow moving cells.
