--The Week ahead

--Weather data

We are looking at a cool and wet week ahead of us. We will see rain showers off and on through next Friday, with some sun breaks mixed in here and there. It's possible we might have a nice sunny day mixed in.

We've had a very long, and unusual streak of unstable weather for our region for the past 2 and a half weeks. Most notably the Friday July 13th storm that blew through the region in the morning from about 8am to 11am. I believe these are the effects of the greater weather patterns coming off of a La Nina pattern in combination with several other factors going on globally. In short we are in an unusual weather pattern that has been generating unstable and humid air. Normally these conditions last 1-3 days and then we are done for the summer. I'm continuing research into this weather pattern and will provide an update within a few weeks on the remainder of our summer outlook.
