Unseasonable heat continues

Picture8

Note: I’ve added a couple of changes to the outlook above. I deleted the noon forecast and replaced it with the weather “headline” for that day. Now, there’s just morning and night rain chances added. You can now simply glance up at the headline and see what your primary weather concern for the day is. If there is a threat for strong storms the box will be yellow, severe storms=red, snow/ice=violet.

Main Threats

Today: Just be safe in the heat and humidity of the afternoon. Heat index values will be around 90 degrees.

Summary

The hot and humid weather continues for today. In fact, this hot and humid pattern looks to hold on for at least the next week or so. Today, we’ll see some isolated showers/storms. That chance increases a bit tomorrow with a disturbance passing through. We go back to isolated storms for Friday before rain chances pick back up for this weekend.

Tropics

The big headline over the past 24 hours has been the landfall of Tropical Storm Gordon along the Gulf Coast last evening. The storm made landfall with maximum sustained winds of near 70 mph, keeping it just under hurricane strength. The storm made landfall near the Mississippi/Alabama state line along the coast. The storm is currently spinning its way across Mississippi.

Gordon will continue to track northwestward toward Arkansas. This will keep the bulk of the moisture to our west.

Hurricane Florence has strengthened more than expected and is now a major hurricane. Winds are now at 120 mph. The storm is well out in the Atlantic but since it isn’t doing as forecast, we may have to keep an eye on this storm. It is no threat to land at this time, but Bermuda needs to keep an eye on this system.

We are still watching the disturbance on the heels of Florence (red-shaded area). The National Hurricane Center (NHC) now gives this system a 90% chance of developing into our next named storm (Helene). Then, there’s another disturbance behind that system that will have to be watched (yellow-shaded area). The NHC gives that system a 30% chance of becoming a named system (Isaac).

Records

On this day in 1954 we were in the middle of a terrible heat wave. The heat wave had been going on for days. This is the heat wave that I’ve mentioned where the airmass here was incredibly dry, giving us chilly nights and very hot afternoons. Our airmass was very similar to that of a desert. On this day that year Crossville hit 99 degrees. Clarksville and Nashville recorded their hottest September temperatures on record (106 and 105, respectively).

Believe it or not, this heat wave pales in comparison to the heat wave we had 29 years earlier in 1925. Wait till you see tomorrow’s heat record for Crossville set that year. I’ll have more on that tomorrow.

On this day in 1975 folks driving across Arizona were caught off guard by a blinding dust storm. Visibility dropped to zero in many locations along Interstate 10. Those horrible visibilities led to a 22-car chain reaction accident on the interstate near Toltec. Two people were killed and 14 others were injured.

Before Hurricane Harvey broke all rainfall records last year, we had Hurricane Easy holding the records. On this day in 1950 that hurricane moved into the upper west coast of Florida and dropped nearly 40 inches of rain in 24 hours. For perspective, we get about 50 inches of rain in Crossville a year. In other words, they received in one day what Crossville gets in nearly an entire year.

News

I could see on the weather map this morning that the seasons are changing. Frost advisories were issued for portions of North Dakota. Fall is coming, folks, just be patient.

I got out and took some pics of the evening sky yesterday. It was a beautiful evening!

I took this one as I was driving home. Look at that big towering thunderhead ahead of me. Notice how its top just spreads out across the sky, as it hits the highest limit of the atmosphere it can rise into.

I took these two pics really close to time for sunset.IMG_20180904_184832IMG_20180904_185318

 

You all have a great day!
