NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Jul 16, 9:40 AM EST, 3 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 1040 AM EDT Mon Jul 16 2012 .DISCUSSION... Vapor imagery and upper air data showed a TUTT cell approaching the GA coast. Our forecast area was under the influence of deep north northeast flow ahead of this feature, which will keep most of our sea breeze fronts (i.e. typically our primary focus for afternoon storms) pinned near the coast. While the enhanced convergence (from the orthogonal synoptic wind) at these fronts often favor the development of several, possibly strong storms along these late in the afternoon, the marginal thermodynamics will likely serve to counter this expectation. The Convection Allowing Models (CAM) do not forecast much deep moist convection today, as they model considerably drying of the boundary layer this afternoon (similar to what we observed Sunday, when surface dewpoints dipped well into the 60s). This would greatly limit updraft strength, and also limit the overall threat for severe storms, though we can not completely rule out an isolated, marginal wind damage event. && .AVIATION... We expect prevailing VFR conditions through this evening, outside of isolated afternoon and evening thunderstorms. Winds will generally be out of the north at 5 to 10 KT today, except for a mid to late afternoon sea breeze (onshore wind) at KECP. && .TAE WATCHES/WARNINGS/ADVISORIES... AL...None. GA...None. FL...None. GM...None. && Fournier
