Post Christmas Frontal Boundary Marches Through

Pencil line of clouds  tracing along the cold frontal convergence at low levels extends well beyond this image to the SW into the Gulf denoting the frontal boundary which steadfastly marches across the state, plowing the land cape of warm moist air along its treacherous path
TODAY: Post-Christmas Cold front is  careening  across the state this afternoon with no holds barred. Severe weather not expected, nor nary a 'strong' storm. Although, there is some thunder and lightning here and there along that line, it is always possible a quick shot of 'strong' could occur due to wind gusts alone, thunder or no thunder since winds just above the deck are primed and ripe for the pickins of random gusts toward 45 -  55mph if one is at the right place at the right time. 

The southern orange line marks the most south I'm thinking any possible thunder might occur. As of this hour, even that might be a stretch if the Meso Scale analysis page is correct , showing much drier air across Central Brevard and south. However, it appears the moist air supporting the showers and thunder is moving along with the front it'self, so that it could be that further south it will be a matter of the setting sun and slightly weaker wind fields that will no longer support that aspect of the front beyond showers. In any case, would expect that no one location will see rain in the area any more than one hour if even that, some locations will see none.  

Otherwise, the best timing for 'instability meets wind fields aloft could be getting ready to occur in the next hour or so, which means a stronger storm or two could pop up along the line from Southern Volusia toward Central Brevard before the sun gets lower and the stronger and more favorable wind fields in the lower levels pull offshore to the east.  That would be from 1pm -3:30pm.

TONIGHT: Expecting a steady temperature drop across the Central and South immediately following frontal passage, with the most notable nose-dive across most of Central from 7pm -11pm, falling into the mid-upper 40Fs.  Lower 40Fs are possible away from the coast but all in all this cold spell will be less notable than the previous since 1) we've already had the experience of the first cold spell; 2) it does not look like it will be as windy with this one   as it was during the previous cold front 3) It will be cool Thursday but a warm up will commence toward late Friday afternoon in to the evening especially along and east of A1A up and down the coast as winds ease on shore, so it will not as prolonged.

WEEKEND: Cool in the morning on Friday but the immediate coast east of US1 will hardly be fazed as winds will lightly keep overnight lows up several notches from that of inland locations. Next front slated for Saturday afternoon,  appears so far that it will be more wet that today's. Much of Saturday we'll be dealing with  either from cloud cover and or rain with possible thunder as it stands today. Update on that aspect likely will be necessary, and suspect the rain chance might go down with time. Instability might be lacking too much to result in strong storms this coming Saturday time frame as well.

BEYOND; Yet a similar cool down and nearly as much as a gradual warming before yet another boundary proceeds through. We are approaching the 'core of Florida usual worst' as far as Central and South go for winter, which not always but most often is in the January 9th to February 21st time frames for consecutive cold day potentials.
