Summer ... Then Fall

We blogged much of last week about a major pattern change coming for this week, and it is still on track.  Below is the latest forecast from the GFS Model, valid at 7pm CDT on Wednesday, 10-27. 

As you can see, a strong cold front is still shown sagging southward through the Plains at that time.  This front will bring much cooler conditions to the central & southern Plains states for the 2nd half of the week.

In Texas, highs will only be in the 70s for much of the sate on Thursday and Friday.  This will seem even more dramatic coming in after summer-like heat in the 90s for some parts of the state today and Tuesday!
