MM’s Fri Wx Forecast for Sept 9

GOES-4, known as GOES-D before becoming operational, was a geostationary weather satellite which was operated by the United StatesNational Oceanic and Atmospheric Administration as part of the Geostationary Operational Environmental Satellite system. Launched on September 9, 1980, it was used for weather forecasting in the United States, and later in Europe. Following its retirement it became the first satellite to be sent into a graveyard orbit. (Side note: I had the opportunity to witness the launch of GOES-17 in 2018. We’ve come a long way since #4!)

This Week’s Hazards

Wx Summary

Much of today is expected to be dry for a great many of us, though there is that risk for a mainly afternoon or evening shower or storm. Rain coverage is expected to increase late tonight and those elevated rain and storm chances stay with us through the weekend. The warm and very humid airmass will lead to the risk for some of that rainfall to be heavy. Be careful if you drive through any of that. By Monday, a strong September cold front sweeps through the area and will bring us our first really good taste of fall. Some of us will likely drop into the 40s for overnight lows Monday night!

Five-Day Outlook

Weather Forecast

Friday: A chance for showers and thunderstorms in the afternoon and evening, increasing in coverage overnight. Overnight rainfall could be heavy.

Saturday & Sunday: Rain and thunderstorms likely. Some of the rainfall could be heavy.

Monday: Scattered showers in the morning. Turning cooler.

Tuesday: Mostly sunny and cooler.

HRRR Radar Model

This radar simulation runs from 9:00 a.m. to 11:00 pm. That moisture to our south moves north overnight.

Severe Weather Safety 

Some of us could see some heavy rainfall late tonight and through the weekend.



On This Day 

1971 – Hurricane Ginger formed, and remained a hurricane until the 5th of October. The 27 day life span was the longest of record for any hurricane in the North Atlantic Ocean.

1989 – The first snow of the season began to whiten the mountains of Wyoming early in the morning, as for two days a moist and unusually cold storm system affected the state. By the morning of the 11th, a foot of snow covered the ground at Burgess Junction.

The drought map is updated each Thursday, so this is the latest map. Drought conditions continue to improve across the state. Much of the state is now free from dry areas. For more drought info, please see my link at

Estimated population in drought Areas in TN last week = 35,220

Estimated population in drought Areas in TN this week = 16,377

Snow Cover Map

The first significant snow in the country for the season is expected across north central Wyoming today and tonight. This map will be interesting to watch in the coming months!

Hurricane Forecast 

Hurricane Earl has behaved rather unexpectedly and is no longer expected to become a major hurricane, though that chance isn’t completely zero.

We now have three other areas to watch in the eastern Atlantic over the coming week to ten days. It’s too early to know what, if any, impact those will have on the US.
