Radar clean across the area this afternoon. Still dealing with the
Post frontal clouds as the upper trough axis has yet to pass
through. Temperatures have been dropping slowly through the day
but no significant cold air behind this front. Temperatures this
Christmas evening will drop into the 30s and that is assuming the
clouds will break later this evening.

Christmas day...nice and dry with seasonal temperatures. Hope you
have a very merry Christmas. Friday is a very nice day with highs
around 60 and dry weather.

The weekend...nothing short of wet. Upper ridge will build over
Cuba with southwesterly flow aloft over the deep south. Impulses
will ride over the region with southerly lower level flow
bringing in the moisture. High probability of precipitation from Saturday lasting through
Monday morning.

A brief break may take place Monday through Tuesday and then
another round of showers is expected late Tuesday night through
Thursday. Will not go as high on the probability of precipitation in this time period just
due to typical timing issues. Although there will be some cold air
nearby...12z temperatures and thicknesses support rain.

00z taf discussion.

VFR conditions currently across the terminals. Cloud cover persist
at the terminals and extends as far west as eastern Oklahoma. Model
soundings indicate that clouds will hang in through much of the
overnight hours with VFR ceilings around 3-4kft. Could see some
periods of MVFR ceilings overnight but not confident enough to
include in the tafs. Clouds will begin to scatter out tomorrow
after sunrise from west to east.
