Storm Team Monday evening forecast (08/12/2013)

We're experiencing one of the warmest spells of the summer season thanks to the presence of a deep high-pressure system through most levels of the atmosphere, positioned right over the north Florida area.  This has prevented most rain and storm activity, keeping extended sunshine and sinking air upon the region and allowing afternoon readings to easily reach the upper half of the 90s.  Overnight, the sky will be generally clear with light winds, helping lows to fall into the middle 70s.  The upper high begins to shift and weaken, yielding to an advancing disturbance from the northwest.  Highs will still reach the middle 90s, but a few scattered thunderstorms will be possible.  Later this week, more unsettledness plus tropical moisture will lead to higher rain chances and an elevated heavy rain risk.
