Fortunately the models continue to show the highest rainfall amounts well off the
coast in the Gulf that the area should avoid the heavy rainfall
threat. That`s not to say we will not get any rain in the area
because we are still looking at a good 1 to 3 inches of rain
across the area for the 5 day period next week. It just looks like
those isolated higher amounts will stay of the coast and not be a
problem for the area. Keep in mind this is still the extended
forecast and we`ve seen the second shortwave trough change in
timing for Wed/Thur quite a bit with the last day or two`s worth
of model runs.
The 12z Euro is more aggressive with rain.

Average High Temperature- October 15 to November 15th...Now, Srain can extrapolate more on this since he is a pro met and a long range guy, but look at the cool colors...:)

And here I was thinking all the orange in Florida were areas of voter fraud...lol. But yes, Srain is the one to go to for enhanced insight :)

I really don’t see any signs on the models of any cold air coming the next couple weeks and neither does the CPC. We need cold air to build in our source region (western and northern Canada) and a 1050mb+ high pressure to drive it south and I don’t see any signs of that happening on the models. The FV3 hinted at it a couple days ago, but now has lost it.

It looks like our next shot of cold air (and maybe a storm) may arrive by the first half of December, as usual models will flip flop as they try to resolve this complex pattern. Btw we don't need a 1050mb+ high to get cold enough for a winter storm in fact a high too strong can make us too dry for precipitation to form. Even a high in the upper 1030mb's can be cold enough for winter weather as long as you have a storm system that can "dig" enough to tap into the cold air.

I’m talking about when the high is in Canada though or near Montana/Wyoming. I know we would probably be too dry if it were that strong anywhere near Texas. 1030-1040mb seems to be the right strength around here, but correct me if I’m wrong.

One last today of 'warm' temperature and partly cloudy conditions before a shallow modified Canadian front arrives tomorrow afternoon/evening. This shallow cold front will drop temperatures into the 50's for daytime highs and possibly 40's for morning lows, particularly N of I-10 throughout most of the Thanksgiving Holiday week. Rain chances return tomorrow afternoon along and ahead of the cold front and rain chances remain in the forecast through at least Thanksgiving Morning. The can be summarized as wet & dreary as a series of upper air disturbances roll across our Region and a very pesky Coastal trough keeps our weather unsettled. The heaviest rainfall does appear to remain offshore, but there is a chance for elevated storms particularly on the busy Wednesday before Thanksgiving Travel Day. Pack your patience if you plan on flying out of SE Texas Wednesday!
