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.
