Main Threats

Tonight: The coldest temperatures of the season thus far. Remember the three ‘P’s of bitter cold nights….People, Pets, and Pipes. Check and make sure all three are ready for these temps.

Saturday: Strong t-storms/ heavy rainfall possible (monitoring).

Summary

These clouds just absolutely love our plateau and they are in no hurry to leave. I wouldn’t be surprised if they hang around all day, but I optimistically look for some peaks of sun today…sometime..  You know how clouds like to hang around up here! I still wouldn’t be surprised to see some flurries today, too.

The breeze today will make our temperatures feel much colder. Right now, at 8:50 a.m., we have an air temperature of 24 but a “feels like” temperature of 19. It’s cold!

Tonight, we will likely have our coldest night of the season.  A few weeks ago I forecast 15 degrees for an overnight and we ended up only going down to 25. That was because the clouds held on through the night and kept us 10 degrees warmer. Could that happen tonight? It’s certainly not impossible but I sure wouldn’t count on it. I’m thinking the clouds will clear out after dark, for sure, and that will set the stage for a temperate drop that should take us down to 14-16 degrees.

The clearing line is moving across West TN right now but it is absolutely crawling. Many of us could literally walk faster than this clearing line is moving. Still, it will get here sometime. ha

Wednesday will be another cold day before a warm up begins for us on Thursday. Unfortunately, with that warmer air comes rain. By Saturday, we could see some storms across the plateau. Some of those storms may be strong, especially for you folks south of I-40. I’ll keep an eye on it. Right now, Saturday is not looking good at all for any outdoor activities, but Sunday looks good, with partly clouds skies and highs in the 50s. Let’s hope that doesn’t change!

Just FYI, if you or anyone you know is traveling north into Kentucky today be advised that winter weather advisories are being issued there for freezing drizzle/flurries that have created some slick roads. The light blue-shaded advisories over in the mountains are wind chill advisories. The wind chill factor could drop to 10 below zero at elevations above 3,500 feet today. Brrrr

Discussion

I’m still keeping an eye on Saturday. A very powerful storm system will bring a surge of warmer air into our region during the day Saturday. At the same time, the atmosphere may become supportive of strong/severe thunderstorms. The greater threat looks to be to our south, across southern Middle TN, Alabama, and Mississippi. Those southern Middle TN storms are a bit close for comfort, so I’ll keep an eye on it.

Records

Whenever particulate matter from ash gets into the atmosphere, it can cause the most spectacular sunsets you have ever seen. I’ve even notified you all when I hear there’s a lot of dust/ash in the atmosphere from dust storms or fires out west. We often get the most vivid reds and oranges in our evening sky, as a result of light’s interaction with that particulate matter.

On this day in 1883, ash caused quite the concern in the Northeast U.S. The Krakatoa Volcano in Indonesia had erupted in late August, sending ash high up into the atmosphere. The sunset was so vivid by this day in November that folks thought New York City was burning. Fire engines were called out across the city but there were no fires to be found; just the red afterglow of the sunset. New Haven, Connecticut had the same issue….fire engines sent out across the city but no fire.

Krakatoa was a remarkable volcano. The force of the volcano was estimated to be about 13,000 times more powerful than the bomb dropped on Hiroshima. The explosion of the volcano was heard for 2,200 miles! That would be similar to us hearing an eruption that occurred near Seattle, Washington! Even if you did survive the volcano you’d be deaf! ha

This Time Last Year

A year ago today we were dry and 61 degrees. That high came after a morning low of 27. For perspective, we may not get much above 27 for a high today!

News

Yesterday afternoon NASA successfully landed InSight onto the surface of Mars! This is the first Mars’ landing since 2012. InSight is capable of drilling up to 15 feet below the surface, giving us info about the subsurface of Mars that we have never had before. What an exciting day for science! NASA published this on behalf of Insight, concerning the picture below, “My first picture on Mars! My lens cover isn’t off yet, but I just had to show you a FIRST LOOK at my new home.” Good luck, InSight!
