Temps dropped overnight with cold front passage. The front also scoured out summertime humidity.

BNA recorded the drop:

In 12 hours the temp dropped 15° (74° to 59°) and the dewpoint dropped 19° (71° to 52°). #ColdFront #GoodbyeSummer pic.twitter.com/9ESIhcN9Tg read more

Tonight’s rush hour is greeted by a broken line of inconveniently timed downpours. A summer-ending cold front is the cause. Cooler and much drier air spills in here around and after midnight.

This is the last day of our summer airmass. Goodbye muggy dewpoints (near 70°)! With clouds, our high temp will only hit 84°.

Here’s the map at 6 AM. Notice all the warm air. But look to the left (west). That’s a cold front and it’s moving east. read more

Hurricane Michael Update

Hurricane Michael strengthened to a category 2 hurricane overnight. It’s still expected to reach Category 3 (major hurricane) status before pushing inland tomorrow.

A cold front from the west will act to guide this storm up and out of the gulf, turning it to the northeast. As seen here on the NHC’s updated track, Michael should miss us all together. read more

Goodbye Summer!

FINALLY! Relief is in sight. But first, we need to get through the early part of this work week.

Temperatures today will again reach the upper 80º range. Looking at a high temperature of 88º in Nashville, with dewpoints in the upper 60ºs through much of the day. Isolated showers and storms will remain possible. However, not everyone will see them. read more

Imagine a typical summer day. Isolated showers and storms, hot, humid, etc. Now put that in October and voilà, you have today!

The HRRR model shows isolated showers and storms will be present this afternoon. Keep an umbrella and/or a rain jacket handy just in case you are one of the few who get stuck under an isolated shower this afternoon. read more
