Ending September on a Cool and Pleasant Note

It was as if we flipped the switch from summer to fall in a span of 36 hours.
We went from high temperatures in the 90's, to high temperatures in the 80's, and from morning lows in the 70's to the 50's.

The image above shows our morning lows from earier today. Most areas bottomed out in the lower 50's, with a few areas briefly touching the upper 40's.

With a cool and dry airmass in place, the next couple of mornings will see similar readings. That means you might actually need that windbreaker or sweater when you head out the door in the morning to work or school.

The cold front that brought in the cooler and drier air came from a big shift in our overall weather pattern.

Right now, we have a big dip in the jetstream across the eastern half of the United States. It is that big dip or trough, that has brought down some Canadian air into East Texas.

The good news is that this weather pattern will not budge much for the next several days.

This not only means more clear nights and sunny afternoons, but also means no tropical systems will invade the western Gulf.

We currently have another tropical depression, which formed earlier today in the Caribbean. We don't have to worry about that depression heading our way as the trough of low pressure across the Southeast U.S. will help steer that system into Florida and areas along the Atlantic seaboard.

If you have the opportunties to make outdoor plans (play golf, tennis, etc), go ahead and do it over the next week and a half or so.

After all, this weather pattern will eventually change. It will just come later rather than sooner.
