It's funny how it's been a much different tale this winter for North
Florida vs. South Florida.... S. Fl has spent much of the winter way above normal with the last few weeks finally being near normal!

NWS 2/12 8AM extended for South Florida
In the extended forecast...models are coming into better agreement
on timing of frontal passage on Wednesday...with the GFS solution
closely matched with the UKMET/ECMWF/CMC suite in indicating frontal
passage across the northwest counties by early afternoon...and
across the southeast by early to middle evening. With westerly flow
in place...expect Wednesday to be very warm for all locations...
but this will be the last warm day for quite awhile as upper low
and associated surface cyclone undergo rapid deepening over the
northeastern states...allowing a very cold Arctic airmass to come
crashing southward across the central/eastern Continental U.S.. there is
still a signal for some light rainfall on Thursday night and
Friday...but the greatest concern in the extended forecast is the
potential for a freeze across at least a portion of the area on
Saturday morning. Will continue to trend temperatures colder than
any available guidance...with forecasted position of surface high
allowing for a good northerly fetch down the peninsula.

Yep. I saw all that convection this morning on Radar. The keys got pounded. Here in Ft. Lauderdale we are getting much needed rain. Not to heavy like the Keys. Can't wait till the cool air gets here this week. Free AC!

NWS...2/12 South Florida
Then Thursday a Canadian 1040 high will be dropping south across the central
sections of the Continental U.S. With high building in across Florida. At this
time thickness values for the 1000-850 mb layer looks low enough
to potentially support near freezing temperatures in the northwest interior
particularly with the GFS continuing to show high dropping all the
way over the state by Friday night. Needless to say the uncertainty
of this kind of forecast is high at this time...but the synoptic
setting is that of a potential cold weather event and will have to
watch closely over next few days.
