MM’s Tues Wx Forecast for Aug 16

Mars may be a cold, dry planet but its weather is dynamic. A wide angle cameras on board the Mars Global Surveyor (MGS) spacecraft watched the development of this large scale storm system above Mars’ north polar area. These frames were recorded on successive mapping orbits at intervals of about 2 hours, with the white north polar cap near the center of each. High winds seem to mix the brownish dust clouds and white water-ice clouds as the curling storm front churns over the extreme northern martain landscape. The MGS cameras have watched similar storms in this region during the months of July and August revealing surprisingly complex weather.

Wx Summary

A weak disturbance is bringing some clouds to the plateau today. Those clouds may drop an isolated shower on the region today but most of us should stay dry. Models have trended drier with both Wednesday and Thursday’s forecast, though there are still low rain chances on each of those days. By Friday and Saturday, scattered showers and storms should once again make their way onto our radar, with those chances being set at about 50%.

On This Day 

2007- In the midst of one of the worst droughts in Middle Tennessee’s history, the temperature at Nashville climbs to 106 degrees, setting a record high for the month. It is the fifth consecutive day with 100+ degree readings — the 9th in the last ten days — and also the twelfth consecutive day of at least 99 degrees. Waverly sets a new all-time record high with a 106-degree reading, and Linden ties its record high at 105.

1989 – A solar flare from the Sun creates a geomagnetic storm that affects micro chips, leading to a halt of all trading on Toronto’s stock market.

MM’s Mon Wx Forecast for Aug 15

Caputured by te Rosetta spacecraft, this dramatic outburst from the nucleus of Comet 67P/Churyumov-Gerasimenko occured in August of 2015, just hours before its closest approach to the Sun. Rosetta was too close to see the comet’s growing tail. That tail is part of what we call the comet Swift-Tuttle.

Wx Summary

The new workweek starts off with partly to mostly sunny skies and an increase in humidity. That warmth and humidity will lead to a 20% chance for an isolated, mainly afternoon shower or storm for today. Lack of any lifting mechanism may limit rain chances on Tuesday to 10%. Rain chances kick up for our midweek Wednesday forecast and those elevated rain chances stay with us through the end of the week.

On This Day 

1967 – The Sundance fire in northern Idaho was started by lightning. Winds of 50 mph carried firebrands as much as ten miles in advance to ignite new fires, and as a result, the forest fire spread twenty miles across the Selkirk Mountains in just twelve hours, burning 56,000 acres. The heat of the fire produced whirlwinds of flame with winds up to 300 mph which flung giant trees about like matchsticks. 

1635 – First recorded north American hurricane hits the Plymouth Colony.

MM’s Sun Wx Forecast for Aug 14

The first image of the Earth from the distance of the Moon, taken in August of 1966. The Lunar Orbiter 1 spacecraft became the first U.S. craft to orbit the Moon on August 14, 1966. This was only 133 days after the Soviet Luna 10 became the Moon’s first artificial satellite. The picture above was taken by the Lunor Orbiter 1.

Wx Summary

A very nice Sunday is in store for our region, as high pressure remains in control. That high pressure will be holding off a disturbance passing to our north today. That disturbance may send an isolated shower or storm onto the plateau this afternoon or evening. That rain chance is only 10%. The new workweek starts off with partly to mostly sunny skies and an increase in humidity. That warmth and humidity will lead to a 20% chance for an isolated, mainly afternoon shower or storm. Rain chances tick up just a bit by the middle and latter part of the week, though chances remain rather isolated.

Five-Day Outlook

Weather Forecast

Sunday: Mostly sunny. A bit more humid. A very slight chance for an isolated afternoon or evening shower or storm. Southwest wind at 5 mph.

Monday & Tuesday: Partly cloudy with a chance for mainly isolated afternoon and evening showers and storms. Humidity increases a bit more. Northwest wind at 5-10 mph.

Wednesday & Thursday: Partly cloudy, with a chance for isolated showers and storms, especially in the afternoons. Light north wind at 5 mph.

On This Day 

1987 – Slow moving thunderstorms deluged northern and western suburbs of Chicago, Illinois with torrential rains. O’Hare Airport reported 9.35 inches in 18 hours, easily exceeding the previous 24 hour record of 6.24 inches. Flooding over a five day period resulted in 221 million dollars damage. It was Chicago’s worst flash flood event, particularly for northern and western sections of the city. Kennedy Expressway became a footpath for thousands of travelers to O’Hare Airport as roads were closed. The heavy rains swelled the Des Plaines River above flood stage, and many persons had to be rescued from stalled vehicles on flooded roads.

1945 –  V-J Day, Japan surrenders unconditionally to end WW II (also August 15 depending on time zone).

Drought Outlook 

The drought map is updated each Thursday. This week’s map shows improving conditions across Middle and East TN, where the only dry conditions to be found are across western Middle TN. West TN’s drought conditions improved from last week. The estimated number of Tennesseeans in drought conditions is 1,793,835.

Hurricane Forecast

The disturbance in the Gulf that I’ve been tracking for several days is moving onshore today and only limited additional development is possible. Showers and storms did organize somewhat better around that system this morning, so the chance of developing into a tropical depression or storm was left at 10% by the National Hurricane Center. Heavy rainfall is expected across southern Texas through Monday because of this system.

Look for the Perseids this weekend! They’re visible anytime tonight.

For the best chance of seeing a meteor, look northeast, toward the end of the Big Dipper’s handle.

Wx Summary

A very pleasant August Saturday is in store for us today, with comfortable temps and low humidity. It’s a great day to get outside! Clear to partly cloudy skies tonight will make for some good night sky viewing, so take advantage of that, too! By Sunday, humidity increases just a bit but it should still be a pleasnant day. Humidity returns for next week and that will create at least slight chances for isolated showers and storms each day, espcially in the afternoon.
