Meteorologist Mark’s Severe Wx Concern


Hazardous weather is not expected over the next 7 days.

On This Day in Wx History

1870- Official weather record-keeping begins at Nashville. The observation site was located in a building at 70½ Cherry Street (between Church & Union Streets).


Yesterday’s National Temperature Extremes

High: 104° at Winterhaven, California 

Low: at Poplar, Montana

Tropical Outlook

Tropical Storm Epsilon is not expected to become a hurricane until Thursday now. The storm’s track has also changed and it now looks like it will spare Bermuda, though it could be a very close call.

I’m still monitoring that area of disturbed weather that will likely develop in the Caribbean over the coming days. Development is not expected before this weekend.

Today’s National Wx Hazards

There are several areas of unsettled weather today across the country, but widespread hazardous weather is not expected. Some localized hazardous weather, associated with freezing rain, is possible today across portions of Minnesota and Wisconsin.

Tomorrow’s National Wx Hazards

Accumulating snowfall is likely across North Dakota and Wisconsin, while freezing rain falls across parts of South Dakota. Snow, heavy at times, will also fall across western Montana. A wintry day for the northern plains and Upper Midwest!

 8 – 14 Day Outlook

Cooler and drier weather overtake the country in the 8 -14 day outlook!



Weather Shots

It has now been determined that the August derecho across the Midwest was the costliest thunderstorm disaster in U.S. history, with over $7.5 Billion dollars in damage. This is a disaster that many areas continue to try to recover from.

Pictured below is the incredible radar imagery of the line of storms as they progressed across the Midwest region.

NASA Nerdology 

Curious about space food? We’ve come a long way from just tubes and packets. In 2017, Italian astronaut Paolo Nespoli was missing his favorite food, so International Space Station managers sent the ingredients for an out of this world pizza party! Making me hungry, NASA!

You all have a great day!
