Today: A 40 % chance of showers. Mostly cloudy, with a high near 80. East wind between 10 and 13 mph. 


Tonight: A 30 % chance of showers, mainly before 1am. Patchy fog after 1am. Otherwise, mostly cloudy, with a low around 65. East wind between 6 and 10 mph.


Forecast Details: Isentropic lift associated with strong warm air advection just above the surface will interact with increasing moisture off the Atlantic to generate scattered showers today. NAM BUFR soundings indicate potential for up to 1000 j/kg SBCAPE today. This forced US to give some consideration to the idea of adding isolated thunderstorms in our Florida zones today, but after collaborating with neighbors decided to keep it out, as mesoscale models are just not showing much convective type reflectivity today. Difficult temperature forecast today. Increasing heights and warm air advection favor a decent warm up but decreased insolation due to cloud cover should inhibit maxes from getting too out of hand. Could still see some highs in the low 80s across our southern zones where more sun is expected.

Will favor NAM guidance for min temperatures tonight. Feel that MOS guidance may be too cool given expected cloud cover and strong warm air advection pattern. This translates to a very mild late November night with lows only in the middle 60s across most areas. Surface warm front will lift north across the area, so a fewlight rain showers will be possible (~30%).
