Tonight Cool, Scattered Rain Showers – 10 PM Temp 54

The story for tonight will be the chance for isolated showers ahead of an approaching “impulse” of energy. These Isolated storms are driven by cold air aloft and other upper level features. A few isolated showers will produce briefly locally heavy rain and the possibility of small hail.

Saturday – Morning Rain, Cool – Wake Up 46, High 67

The aforementioned “impulse” will bring another chance of showers and thunderstorms during the morning hours. These showers will stick with us here in Nashville until a little after lunchtime.

The NAM “TechnoFutureSimulatedRadar” between 7 PM Friday and 4 PM Saturday paints the picture well.

The above is more of a “medium range” model. It really soaks us. Short range models are suggesting the bulk of the heavier morning rain will scoot south of us. For example, the RAP model at 9 AM:

We’ll be commenting on this more tonight @NashSevereWx on Twitter with updated model information.

None of the showers will be severe here in Nashville Saturday morning. In all, less than a half an inch of rain will fall.

A second impulse is expected to track through Middle Tennessee on Saturday afternoon, but the last several model runs seem to be ignoring this feature as a rain producer. The NWS still has us down for a “slight” chance of rain Saturday afternoon into the evening hours.

We will remain mostly cloudy throughout the day and night Saturday.

Sunday – Morning Rain, Partly Sunny – Wake Up 49, High 70

As the upper level feature that has kept us soggy and cool the past couple of days pulls off Sunday morning, we will have another slight chance for showers.

The NAM “TechnoFutureSimulatedRadar”, Depicting 7 PM Saturday to 1 PM Saturday, shows rain moving through, but mostly staying south of Nashville.

These showers will be out of our hair a little before noon. Once the showers pass, we will become partly sunny during the day and continue to clear over night.

Warmer temps and clearer skies ahead!
