A nice weekend to get outside

Main threats

No significant threats in sight.

Summary

We’ve got some nice weather ahead of us, folks! Sure, it will be a bit breezy today but at least we’ll have lots of sunshine! That sunshine holds on for us right on through our Saturday, making for a great day to get outside and enjoy that spring-like feel in the air.

On Sunday, clouds should start to thicken but I think the rain will hold off until after sunset. That could change, as some models want to bring a shower or two in here for the afternoon hours. Never the less, it will be a warm day. If I had anything I wanted to do outside this weekend I’d do it on Saturday just to be safe.

There are already indications that our next big weather maker will move in just in time for next weekend, so be sure and get outside this weekend!

A lightning bolt is hotter than the surface of the sun. In fact, lightning’s sizzling temperature of around 54,000 degrees Fahrenheit is roughly five times hotter than the sun’s surface! Talk about a burn, am I right? 🙂

Records

An unusual late-season snowstorm dumped 10 inches of snow on Murfreesboro and nine inches on Lebanon on this day in 1968.

A display of northern lights was so brilliant on this day in 1920 that people as far south as Bradenton, Florida and El Paso, Texas saw them! The lights were so brilliant near Detroit, Michigan that they obscured the view of stars in the sky.

What to look for in the night sky tonight

The International Space Station (ISS) will be flying over the plateau this evening! It will fly over at 7:45 p.m. and will be visible for six minutes. It will reach a maximum height of 66°. It will first appear 10° above the horizon in the WSW and will disappear 10° above the horizon in the NE. That means you’ll look for it to rise generally in the direction toward Sparta and watch it disappear in the general direction of Oneida.

I’ll have more on this later today, including information about who is on the ISS today!

I printed out a chart of the night sky for 8:00 p.m. tonight. Go out and look up! Notice Mars is colored in purple. Be sure and look for the Red planet! You may only be able to see the brightest objects, as that nearly Full Moon will be drowning the night sky with light. That moon, though, can be quite the sight in itself!

News

Yesterday some of you may have heard or seen some hail falling around the plateau. That was due to a very cold pocket of air aloft that we refer to as an upper-level low. That thing got a little wound up yesterday afternoon and produced some hail. It was actually graupel, which is a soft hail that can fall when it’s too warm for sleet but not quite warm enough for storm-produced hail. In the summer we can get some very strong storms with large hail in these situations. This time of year, they just do what yesterday’s did.

Still, that low got a little rowdier than expected. Upper-level lows are notorious for being a forecaster’s greatest challenge. We don’t have a lot of data from that high up in the atmosphere and so we sometimes get some surprises from these systems. Upper-level lows are the most common culprit for surprise snows in the wintertime (or even early spring).

Some of you probably saw it on Facebook last night but it’s worth repeating here. I surpassed the $2,000 mark for my St. Jude fundraiser!!! I have now raised double what I did last year. This is a good trend to be on, right?

If you’d still like to give you have until April 27th. You can give through the link below. If you’d rather write a check just let me know (mark@weathertap.com).

What an experience this has been!

You all have a great day!
