MM’s Wx Vlog

This Week’s Hazards

Wx Summary

Rain is likely in the morning hours of Saturday. That activity should taper off to just isolated to scattered showers by afternoon and evening. By Sunday, a strong cold front begins moving through the area and that is expected to kick off numerous showers and thundertorms. Some of those storms could produce heavy rainfall. The front clears through the area Monday morning, giving us a pleasant Monday afternoon and evening. That nice weather continues into Wednesday.

Five-Day Outlook

Weather Forecast

Saturday: Rain likely, especially the first half of the day. Just a chance for scattered showers by the afternoon and evening.

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. A taste of fall in the air.



On This Day 

1960 – Hurricane Donna struck the Florida Keys, with winds gusting to 180 mph and a 13-foot storm surge. The hurricane then moved north along the eastern coast of Florida and inundated Naples before moving out to sea. Hurricane Donna claimed 50 lives, injured 1800 others, and caused more than 300 million dollars damage. The Marathon/Tavernier area was almost completely destroyed, and in the Citrus Belt, most of the avacado crop was blown from the trees. Hurricane Donna wreaked havoc from Florida to Maine, with wind gusts to 100 mph along much of the coast. Hurricane Donna produced wind gusts to 121 mph at Charleston, South Carolina on the 11th, and wind gusts to 138 mph at Blue Hill Observatory, Maine on the 12th. The hurricane finally died over Maine two days later, producing more than five inches of rain over the state.

1987 – A late afternoon thunderstorm roared through Austin, Texas producing wind gusts to 81 mph, and 2.17 inches of rain in just sixty minutes. The high winds toppled six National Guard helicopters at the Robert Mueller Municipal Airport, and damaged or destroyed numerous other aircraft.

Showers across the north end of Cumberland County on Friday show up nicely on this map. I had nearly two tenths in my rain gage in Rinnie (10 mi north of Crossville).

Drought Outlook 

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

Hurricane Forecast 

The tropics seem to be cooling off a bit. Hurricane Earl will not become the season’s first “major” hurricane (winds over 111 mph) and the other disturbances we’ve been watching are not doing so well today. Still, we can’t take our eyes off the tropics this time of year. The season tends to peak around the 15th of September.
