What was that rain all about last night? We were expecting some and it finally came, but the situation was interesting so wanted to present a theory (of mine) of what happened. You can see above to images: (1) shows the 1k Relative Humidity color coded and average layer winds at the time of the rain (2) shows after the rain had dropped slowly south with time and it was over for central Brevard but still ongoing a smidge further south. (3) furthermore, we see in the last image the sharp dewpoint temperature gradient as marked in black indicating the steep gradient from dry to moist air masses.
It appears we were right on a humidity gradient from very dry to saturated at the lowest levels and they were also being converged because of the differences in the rock solid air masses ... lift was generated...just enough to create rain across the state along the steep gradient line. As it moved south so did the rain, but so did some of the 'forcing' so the rain further south wasn't nearly as strong. We got 0.52 inches at my place.
For today, looks like we are in somewhat moist post-frontal position today with no triggers for rain until maybe very late (other than a possibly detectable spritz under the particularly thicker patches of clouds)...but for the most part it will be dry. I'd expect to see partly to mostly cloudy skies throughout, but the sun will peak out now and then. What might happen after dark is the wind will veer to more easterly doing two things: (1) transporting warmer air in; and (2) creating an inverted trough along the warmer gulf stream...these two factors could easily bring rain back into the equation depending on when the wind shifts...but at this time it looks like well after dark..say about 7pm. So theoretically it could start to rain around 8:30pm. Temperatures will hold just under the 70 notch today all quads but maybe break that threshold right around 2pm. Speaking of temperature, we only got down to 62 right here but know it was a few degrees cooler at most other locales. This was a full 2 degrees warmer than suppositioned it would get down to yesterday. I'll take it.
Things get very interesting on Saturday as our abhorrent cold front becomes friendly and makes a return visit from the south as a warm front during the night. Tonight's lows will be warmer than last's as a result. convergence along the front and the inverted trough could create a possible thunderstorm or two right on the east coast in Brevard County of all places! So will see what happens with that. Also, we'll be back into the low 80s thermally wise. Sweet!
