Baldwin’s Wx Blog for Wed., Feb. 26

Waiting on some snowflakes

Today

Weather Headlines

Rain today, light snow tonight (light accumulations likely)

Snow showers for Friday and Friday night (accumulation likely)

Heavy rainfall and thunderstorms are likely next week. Flooding could become an issue as several inches of rain could fall across the plateau. Strong storms may also be a threat. Stay tuned.

Main threats

Slick roads are possible tonight, as light snow develops across the plateau. Be safe. I think roads will be fine until after sunset.

Slick travel is once again possible (if not likely) Friday through Saturday morning. Plan accordingly.

Heavy rainfall and strong storms may be an issue next week. I will be monitoring this closely.

Summary

Look for cloudy skies and rain showers for the greater part of our day. A cold front will swing through later this morning, bringing breezy north winds and slowly falling temperatures. Our high for the day will occur before noon.

Any afternoon showers will have the potential to have some snow flakes mixed in. Air aloft will cool much more rapidly than the air here at the surface. So, while we’re still hovering above freezing down here, it will be well below freezing up in the atmosphere. That could lead to some snow flakes in the rain this afternoon.

By sunset, temps will be falling to freezing and that means precip will turn to light snow. As northwest winds kick up, uplift along the plateau will encourage more snow showers. Up to one half inch, to as much as one inch, of snow could fall across the plateau. Most of us should stay around one half inch. That’s enough for some slick spots, so be careful.

Another system moves in Friday and that one is looking more impressive as we get closer to time. This may end up being a 1-3 inch snowfall. Stay tuned. Snow should begin late Thursday night and continue through Friday and Friday night, possibly not ending until Saturday morning. If you notice, high temps on Friday are expected to be in the mid 30s, which could limit accumulation, but that temp may end up being colder than forecast. I’m watching it closely!

THEN, we get a nicer Sunday. Let’s hope for some sun because next week is not looking good for sunshine.

Rain, heavy at times, will plague us from Monday to at least Wednesday. We may be looking at 4-6 inches of rain again (maybe more), along with strong thunderstorms by Tuesday. I’ll be watching that closely too!

I have a lot to watch! ha

Records

The third largest snowstorm to ever strike Charlotte, North Carolina hit that city on this day in 2004. Up to 20 inches of snow fell on the city! Close to a foot was measured at the airport, located about six miles away from downtown.

Wayyyyyyy to the northwest of Charlotte…..

On this day in 1910 a fierce storm system produced over 100 inches of snow in some of the mountainous areas from the 24th-26th. That is a single-storm record for Washington State. By the 28th, the snow changed to rain, setting the stage for deadly avalanches that would develop by March.

Wednesday Wx Word of the Day

Clipper

Often referring to an Alberta Clipper, this is a fast-moving system that originates in the province of Alberta Canada. These systems often move southeast across the northern plains, Upper Midwest, and Great Lakes region during the winter. These systems are often accompanied by light snow and colder temperatures.

Sometimes these systems dive down into our neck of the woods, bringing light snow and cold, blustery winds.

NASA Knowledge

Did you know that NASA studied Tennessee’s Flynn Creek Crater when preparing for our first Moon landing? The crater is about halfway between Baxter and Gainsboro. At the time of impact, that area was under a shallow sea. Then, a meteor traveling at 10 miles a second split that water and slammed into the earth. A crater 2.5 miles across was left in its wake!

Early theories were that this odd deformation of land was from a sinkhole or volcano. An astro-geologist finally solved the mystery.

Within this cratered mess is also the world’s only known cave to have formed from the impact of a meteor strike. As the land rose back upward in the center after the initial impact, uplifted limestone eroded away and formed a big cave.

It’s the cave that NASA took interest in. They wondered if such features could exist on other moons or planets, offering shelter for exploring astronauts?

Pretty wild stuff, right?

Pictured below is what the crater would have looked like, except the shallow sea filled the Flynn Creek crater with water, helping preserve it. The outer edges were actually raised above the water.
