Rain slow to move in

What a treat to get sunshine for so long this morning and early afternoon around the Nashville metro area and points east. That has allowed temperatures to rise into the mid 80s in Music City.

Folks to the west have had some clouds and showers.  It has been a slow process to moisten the lower levels of the atmosphere, thanks in part to the upper ridge over the central and eastern portions of Middle Tennessee. The dew points are finally starting to rise this afternoon.

After midnight moderate rain should start to spread eastward. Only moderate instability is expected so that will keep the chances of thunderstorms to isolated. The best chance of rain for western Middle Tennessee will come Thursday morning, where 1.25″ could fall.  Lesser amounts expected elsewhere. Scattered showers and thunderstorms will spread eastward through the day tomorrow.  No severe weather or flooding is expected. Here’s the Futurecast depiction of the approaching system.

The front will most likely pass by late Thursday night or early Friday morning.  There has been nothing fast moving about this system. This will keep some showers lingering into Friday morning.

A ridge of high pressure builds in for the weekend.  This equals lots of sunshine with cool mornings and warm afternoons.

By Monday and Tuesday of next week, another front will provide some showers and thunderstorms to the mid-state.
