Great Weather for Middle Tennessee!

The Friday afternoon web forecast is up and running - just click the link at the top of the blog to check it out.

This afternoon:

Temperatures in the upper 70s and lower 80s and low humidity. At 12:45 PM the dewpoint in Nashville was a very dry and comfortable 45 degrees - much better than the 60 and 70 degree dewpoints we could have this time of June.

Nice weather will continue right through the weekend - check the 7 day forecast above for all of the pleasant details!

For the weather geeks:

The picture below might look like a Jackson Pollock painting, but it’s actually a computer model forecast for this afternoon at around 18,000 feet up in the atmosphere.

The red colors show areas of spin (vorticity) that provide the lift needed for rain and thunderstorms to develop.

We look at these maps to get a feel for “the big picture” - focusing on things like vorticity, troughs of low pressure, and ridges of high pressure.

GFS computer model forecast for 1PM Friday June 17

The pattern this afternoon (the map above) shows a large trough on the west coast, a big ridge of high pressure from Texas through the Upper Midwest, and another large trough over the Northeast. This pattern is called an “omega block” because it looks like the Greek letter omega…and it often takes some time for the pattern to break down.

What’s it all mean? Our cooler-than-average weather will continue right on through the weekend!

Four days from now on Tuesday afternoon (the map below) the pattern hasn’t changed a whole bunch. You can see the ridge of high pressure is still firmly planted across the middle of the country - which is where the warmest weather will remain.

The trough of low pressure (and it’s cooler weather) should still be in place from the Mid-Atlantic states down through the Mid-South.

Enjoy the weather while it’s here - according to the calendar summer kicks off Tuesday the 21st! The forecast will follow suit: upper 80s (and maybe a 90 degree day) will be back in the picture by the middle and end of the next work week.

Thanks for stopping by the blog - we’ll post another video update later this afternoon.
