As a big cold front has moved into the central United States and continues to progress east, severe thunderstorms ahead of the front continue to move through. Behind the front, northerly winds have blown in and temperatures have dropped 10, 20 and ever over 30° in less than 24 hours for many.

National Cool Down

As this front moves through temperatures will drop up to 30°. Some of these areas have been above average for most of September but by the time this front moves into the eastern United States, we may see temperatures drop 5 to 15° below average. Hello Fall weather!

Some cities like Dallas, TX went from 100 degrees on Monday to a high on Tuesday near 80!

Today’s forecast temperatures on average run about 20 degrees cooler behind the front compared to yesterday when looking at the Deep South.

As temps have drastically dropped they’ve also fallen below average for this time of year.

Thursday, the cooler and more comfortable conditions make it to the Gulf coast and I-10 Corridor.

Biggest thing to note with the cooler air will also be the lower dewpoints! This means it’ll be crisp and chilly in the mornings along with very little humidity impacting the afternoons!

The strength of the trough takes the moisture content way down through the end of this week and into the weekend.

The lower the dewpoint temperature the more comfortable it feels in the afternoon.
