MM’s Wed Wx Blog for May 19

MM News

I’m headed to Burks Elementary this morning to get those kids excited about rockets, space, Martian weather, and the mission to Mars! Heck, one or two of them may walk on the Red Planet someday! I’ll be down there all day, speaking to each fourth grade class. If you hear something go boom today, it was NOT one of my experiments we’ll be doing. It was not!

Weather Headlines

A dry trend continues

Temps heating up

Summer-like weather quickly settling in

Meteorologist Mark’s Wx Vlog 

Seven-Day Forecast

Daily Forecast Summary/Discussion

Summer’s here! (ha) That 7-Day outlook is fit more for summer than it is for spring. Also notice the lack of rain. With warming temps, thirsty and budding vegetation, and low humidity we’re going to see things get dry FAST.

The good news is that the lower humidity levels will make it feel a lot better than if it were hot and muggy. We’ll get those days soon enough.

Meteorologist Mark’s Wx Concerns

Almanac for Yesterday

Sun & The Moon 

On This Day in Wx History

1780 – The infamous “dark day” in New England tradition. At noon it was nearly as dark as night. Chickens went to roost, and many persons were fearful of divine wrath. The phenomena was caused by forest fires to the west of New England. 

Yesterday’s National Temperature Extremes

High:  109° at Death Valley, California

Low:   25° at Williams, Arizona, Copper Basin, Idaho, Climax, Colorado, and Rainier Paradise, Washington  

Wednesday’s Weather 101

The atmosphere is layered like a cake. One layer might be dry, while another layer might be moist. Sometimes, the higher up levels are moist, while the layer nearest the Earth’s surface is very dry. This means rain or snow falls from the clouds (were it’s moist) but then evaporates as it descends through the drier layers. Precipitation that evaporates before hitting the ground is called virga.

Sometimes, virga is accompanied by lightning. The lightning makes it to the ground, while the rain does not. This is what causes many of the big wildfires seen out west in the summer and fall.

In the picture below, you can see the rain falling from the clouds in streaks, but it evaporates before making it to the ground. Sometimes, rainbows form from the falling raindrops, even though they don’t make it to the surface.

Today’s Tennessee Weather 

We’ll see a mix of clouds and sun across our Tennessee skies today. Some of those clouds may produce a sprinkle or shower across West Tennessee. Many of us will stay warm and dry.

Tonight’s Tennessee Weather 

It’s a clear to partly cloudy night across the area, with mild overnight lows.

Tomorrow’s Tennessee Weather 

With lots of sunshine and low humidity, temps will warm fast! Many locations may experience some of the warmest temperatures so far this season. It will feel like summer has arrived early!

Drought Monitor

The drought monitor is updated each Thursday.

NASA Nerdology 

Well, someone else finally did it. Until now, only the U.S. had ever landed a rover on Mars. In fact, we just landed our fifth one this year, when Perseverance touched down on the Red Planet. Other countries have worked toward that goal, or even tried it, but China finally landed their own rover on Mars this month. We don’t know a whole lot about it, since it’s China, but we hope they’ll share the info from it.

You all have a great day and keep lookin’ up!
