Weather Headlines
–Rain shrs could turn to snow showers/flurries tonight (no major impacts)
–Rain and snow showers Sunday night and Monday morning (no impacts expected at this time)
–Rain showers return for the middle and end of next week
Main threats
No major threats are anticipated at this time. If temps get colder than expected Sunday night, there could be some impact from light wintry precip by Monday morning. Monitoring.
Summary
One thing that is for certain in the 7-day outlook is that there will be plenty of clouds around. The uncertainty lies with amounts of wintry precip that may fall both tonight and Sunday night. At this time, significant impacts are not expected.
Right now, there’s a band of heavier rain showers that has just made its way through the Nashville area at 8:40 a.m. That band is moving east.
The problem with the wintry precip chances in the forecast is both the amounts of the precip expected (light) and the marginal temperatures for it. It looks like a very borderline situation both tonight and Sunday night. I’ll keep an eye on things and let you know if any guidance today increases our chances of accumulation from either system. Again, both chances are for light precip. Even if all the moisture fell as snow we’d still be looking at a one inch or less situation, as it looks right now.
The next system moves in the middle of next week with more rain showers.

Records
A winter severe weather outbreak produced seven tornadoes across Middle Tennessee on this day in 1997. A maps of some of those tornadoes is pictured below. Notice the very long-track EF-2 that touched down north of Murfreesboro and didn’t lift until it got into western Putnam County. Also, notice that EF-4 south of Murfreesboro. While 31 people were injured in these storms, miraculously no one was killed.

NASA Knowledge
NASA has released some incredible images that The Curiosity Mars rover took of an outcrop called the Murray Buttes region of Mars. The rock striations within the ancient sandstone indicate that the layers are primarily the result of shifting winds on the Red Planet over time. The image was taken on Sept. 8, 2016.

Last night’s MASTER Science class went very well! I had a good attendance and we had a blast learning about winter storms. We even made our own snow! ha
Next month’s lesson will be about volcanoes and how they affect the weather and even make their own weather. Stay tuned for registration!
You all have a great day!
