Fantastic day today…feeling like fall. The rain moved out early and the sun started to peek through. With a light northwest breeze the high in Nashville only reached 75 degrees. It was a nice treat after on and off rain and even yesterdays thunderstorms.
The National Weather Service confirmed a weak EF-0 Tornado yesterday in far western Smith County just across the Wilson/Smith County line. Damage was mostly confined to dozens of trees snapped or uprooted along the 2 mile path. Two barns were uplifted and destroyed off of Hiwasee Road in western Smith County. Winds were estimated at 75-80 mph.
The sky continues to clear this evening, so by tomorrow morning it will be cool and clear. That’s perfect for early birds to see the International Space Station pass by. Look toward the WNW sky at 4:15AM. The ISS is cross the sky for 6 minutes at a maximum height of 50 degrees. It will disappear in the SSE sky.
A surface high takes over so the rest of the day on Friday will be more summer like with a sunny sky and the heat rising to 86 degrees. It will be breezy again, but this time from the southwest. Friday night the Storm Prediction Center has put Middle Tennessee in a “marginal” risk zone for possible severe storms. But the better chance of rain and thunderstorms moves in Saturday and Sunday.
A disturbance moves out of the Ohio Valley Saturday bringing the chance of rain and thunderstorms. Some models show that the atmosphere may be capped on Saturday, not allowing convection to develop. So it could be dry for some with most thunderstorms developing north of I-40. So there is a little uncertainty. Here is one model prediction.
Saturday night into Sunday morning an the approaching front will likely trigger thunderstorms and some could be strong to severe. with damaging wind and hail the largest threats. The Storms Prediction Center has Middle Tennessee under a “slight” risk for severe storms.
As the front passes by on Sunday afternoon another round of thunderstorms is likely.
Best advice this weekend is to have a back up plan for any outdoor activities. Monday will be the drier of the three day weekend.
I’ll have an update on Channel 4 News at 10pm.
