Happy Labor Day!

Main Threats

Today: Heat and humidity this afternoon. Limit your time in the sun and drink lots of liquids.

Summary

These final days of summer are feeling a lot like, well, summer. Expect more hot and humid conditions today, with an isolated shower or storm possible in the heat of the afternoon/evening. That same forecast can be applied to every day this week. We will see highs in the mid to upper 80’s and lows in the mid to upper 60s all this week.

Tropics

The tropics are active, folks, and it’s just in time for the peak of hurricane season. We almost always see the most activity in September and this year is proving to be no exception. We now have Tropical Storm Gordon in the Florida Keys. This storm is expected to strengthen as it moves northwestward into the Gulf of Mexico. This storm is expected to make landfall as a category 1 hurricane along the Louisiana coast on Tuesday night. A category 1 hurricane has maximum sustained winds of 74-95 mph. The National Weather Service defines the impacts of a category 1 storm with the following wording, “Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days.”

Below is weatherTAP’s visible satellite imagery of Gordon over the Florida Keys. The red line is the projected path. On this course, the storm will have no impact on our area.

We still have Tropical Storm Florence out in the Atlantic. This storm is expected to stay out to sea,  the developing disturbance behind Florence may need to be watched. That new disturbance is the yellow-highlighted area and the yellow x.

Records

The same dry air mass that produced the huge temperature swings yesterday is still in place on this day in 1954. The morning low in Crossville was 50 but we topped out at 93 that afternoon. If you think that’s a big swing, Nashville started out that morning at 60 degrees but climbed all the way up to 101 degrees that afternoon!

Incidentally, that heat wave of 1954 lasted a while. I glanced ahead and on the fifth of September Crossville hit 99 degrees. That was one year summer REALLY didn’t want to let go!

Something happens in today’s records that indicates the changing of the seasons is upon us. Today is the first snow record that pops up! On this day in 1961 the city of Denver, Colorado measured 4.2″ of snow. This is the earliest snow on record for that city. Can you believe it’s already getting into this time of year? Now, where’s my Christmas decorations?…….

Speaking of ice…

On this day in 1970 the largest hailstone ever observed fell in Coffeyville, Kansas. The stone was 17.2 inches in circumference and weighed nearly two pounds! This same storm produced average hailstones of five inches in diameter. That’s the average sized stone produced in this storm! Another stone that was recovered was 16 inches in circumference. That was one hail of a hailstorm, folks (ha).

This hailstone remained the largest in the record books until a hailstorm hit Vivian, South Dakota on July 23, 2010. In that storm, a hailstone measuring 18 1/2 inches was recovered by Mr. Lee Scott. That stone weighed just under two pounds.

Interestingly, Mr. Scott planned to make daiquiris out this hailstone but changed his mind and decided to freeze it and show it to the National Weather Service.

You all have a great Labor Day!
