Threats

Data from the last couple of days is coming into much better agreement with our system for Sunday night and Monday morning. Confidence is increasing that we will not see much, if any, snow accumulation. We will see a cold rain and it may mix with or even change to light snow by Monday morning, but the vast majority of that precip is looking liquid at this time. I’ll let you know if anything changes. Again, confidence is increasing that we will see little to no snow accumulation.

Yet another system will bring more precipitation to the region on Wednesday. Once again, we will be looking at rain and/or snow. It is unclear, at this time, what impacts any of that wintry precip will have on our area. Stay tuned.

Meteorologist Mark’s Snow Scale

On This Day in Wx History

1962- It’s the beginning of a record cold outbreak in Middle Tennessee. After nearly three inches of snowfall, Nashville’s temperature drops to 3 degrees. Crossville’s low drops to -2. Brrrrr!

Almanac

Yesterday’s National Temperature Extremes

High: 88° at Rio Grande Village, Texas 

Low: -6° at Stanley, Idaho

Today’s National Wx Hazards

Lots of unsettled weather can be found across the country today, but the hazardous weather will be confined to the northern Rockies and central plains, where accumulating snowfall is likely.

Tomorrow’s National Wx Hazards

Freezing rain will threaten New England and parts of the Pacific Northwest. Accumulating snow continues to threaten parts of the Rockies and plains, as well as parts of Iowa and Wisconsin.

 Weather Shots

The NWS Nashville posted this yesterday on social media. “Crossville is up to a crazy 72.71” of precipitation for the year to date — over 20” above normal! Only 2.18” of additional precip by the end of the month will make 2020 their wettest year ever.” Might as well go ahead and get that other 2.18 inches, right? lol (And SO little of all this precip was snow! ugh)

NASA Nerdology 

On this day in 2018, NASA announced that Voyager 2 entered interstellar space! The heliopause (the outer edge of the heliosphere) is so far away that it takes 16.5 hours for information traveling at the speed of light to reach Earth, in comparison to just 8 minutes for sunlight to reach us!

You all have a great day!
