A nice little break from the summer heat!



Today: Possibility of strong storms

Friday-Saturday: Possibility of strong storms


We’re already seeing a bit more stable air filter in from the north this morning. Never the less, with the humidity remaining high through the afternoon we have to keep a chance for a shower or storm in the forecast. This morning’s clouds are also helping to keep us more stable. That is evident on radar, as anything that develops seems to be struggling to survive for very long.

A July cold front will slip through this evening, and that will really drop our humidity levels. Expect a really nice day on Wednesday, especially for July. Even though the forecast high temp is around 85 degrees, it will feel much nicer due to low humidity values.

That nice air mass will be with us through Wednesday night and most of Thursday, before the muggies invade again Thursday night. Another July cold front will approach and the wind will turn from the south ahead of the front. It doesn’t take long for the air to become humid when we switch the winds from the south in July!

That tropical airmass will provide the ingredients for showers and storms on both Friday and Saturday. It should be the scattered variety, but any storm that develops will once again have the potential to become strong. Our chance for any of those storms reaching severe limits is a bit higher Friday afternoon, so I’ll keep an eye on that. Damaging winds and hail would be the primary threats.

The unsettled weather will hopefully clear out in time for a nice Sunday, but we’ll have to wait and see about that.


Looking at water vapor imagery this morning it is apparent that drier air is knocking at our door. That more stable air will move in from the north and bring such a pleasant day for our Wednesday. I’m also noticing a big complex of storms out over the Plains. It will be interesting to see how this affects our weather today. I wondered if cloud debris from that system will keep us cloudier this afternoon? I expect we will at least see a lot of cirrus clouds blowing off the tops of those storms. You can see those high, cirrus clouds blowing off to the east in the image below, while the main complex of storms drop south.


Once we get into Thursday night, the muggy weather from the Deep South will begin moving back in. The night air Wednesday night will be downright refreshing, while the air Thursday night will be sticky and very humid.

That means that Wednesday night will be perfect for star gazing! Look to your southeast a couple hours or so after dark and you’ll see a big red “star” in the southeast. It will get higher in the sky and brighter as we go through the night. That, my friends, is Mars and it will be brighter this month than it has been in nearly 20 years. Check it out, you can’t miss it!


All is quiet in the tropics.


When we look at the summer we’re having, we can say that it hasn’t been all that bad. We’ve had some hot days, but they’re always broken up by some brief bouts of cooler weather. Sometimes that’s because of the rain and sometimes it’s because a cold front made it all the way down to Tennessee and gave us a shot of nicer air. But, in 1934 there was little relief to be found from the heat.

One of the worst heat waves in U.S. history was taking place on this date in 1934. The final two weeks of July would create records across the eastern half of the country that, in many instances, still stand today. By the time the heat wave was over, 679 lives had been lost in Michigan alone! About 300 of those deaths were in the city of Detroit. Think about it….heat wave….1934. Forget turning on the air conditioner.

Seven years later another heat wave would hit the U.S. , but this time it was the Pacific Northwest’s turn. Heat waves in this area are unusual but when they hit they’re bad. Even today, folks don’t have air conditioners up there (who needs it?). The vegetation is so lush that when it dries out it can be a disaster. When the heat wave of 1941 hit it came to an end with a storm system that brought some relief but it also brought storms. The lightning from these storms hit the dry underbrush and by the time July 17th came to a close, at least 598 forest fires had been started.

On a lighter note, on this day in 1957 a very powerful dust devil spun up in a neighborhood near Wilmington, Delaware. The dust devil tore most of the roof off one house and unshingled a neighboring house! That was one crazy dust devil, folks!

You all have a great day!
