MM’s Fri Wx Forecast for Sept 2

On September 2, 2017, Astronaut Peggy Whitson returned to Earth after accumulating 665 days in space over the span of her career. That’s more days in space than any other astronaut. Whitson also became the first female astronaut to command the International Space Station twice, and broke the record for the longest single space flight by a woman at 289 days in orbit before returning aboard Soyuz MS-04. Whitson holds the records for the oldest woman spacewalker and the record for total spacewalks by a woman.

Wx Summary

Humidity begins increasing today and that means an end to the pleasant overnight/morning temps we’ve been enjoying. That heat and humidity also means an increase in afternoon/evening shower and storm chances for today. An approaching frontal system moves in for the weekend and that feature, coupled with heat and humidity, will give us a good chance for scattered showers and thunderstorms through the Labor Day holiday. Those rain chances are all-day chances and not necessarily confined to the afternoons. By Tuesday, rain chances should lower somewhat, though that forecasat is quite uncertain at this point.

This Week’s Hazards

MM’s Wx Vlog 

Five-Day Outlook

Weather Forecast

Friday: Mostly sunny & hot. Humidity begins increasing, which also increases the risk for an afternoon shower or storm. Southeast wind at 5 mph.

Saturday & Sunday: Scattered showers and thunderstorms likely. Southeast wind at 5 mph.

Labor Day: Showers and thunderstorms likely. South wind at 5 mph.

Tuesday: Scattered showers and thunderstorms.

MM’s Severe Wx Concerns 

Widespread severe weather is not expected through the Labor Day weekend, but be advised that any outdoor plan is certainly compromised by storm chances. Those storms will contain cloud-to-ground lightning, heavy downpours, and gusty winds. Keep an eye on the radar and have an indoor back-up plan for any outdoor activity. Remember, if you’re close enough to hear thunder (even if the sun is shining!) you’re close enough to be struck by lightning.

Forecast Precip Totals for Today

Colors are showing up in Alaska! We’ll follow the changing foliage to Tennessee in the coming weeks!

Drought Outlook 

The drought maps update each Thursday, so this is the latest map updated on September 1. Some areas of the western side of the state are beginning to get dry again. Hopefully, rains over the Labor Day weekend will help them out.

Estimated population in drought Areas in TN last week = 145,099

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

Hurricane Forecast

Tropical Storm Danielle is packing winds of 70 mph this morning. That system is moving east and away from the U.S.

The red-shaded region is expected to develop into a tropical depression or storm at any time. A Hurricane Hunter is scheduled to fly into that system this afternoon. The system may pass between Bermuda and the Carolinas. That track is being monitored very closely by the National Hurricane Center.

The yellow-shaded region is encountering many issues and will likely dissipate over the next 24 hours.
