     We're allowed another sunny summer day with highs reaching the low 80s this afternoon. Weak high pressure will give way to a series of cold fronts that will plunge south out of Canada. The first system will begin with cooler temps and scattered rain showers tonight through early Wednesday. A second cold front will usher in another cool blast and better chances for rain showers and possibly a rumble of thunder Thursday. We'll be grabbing for the hoodies & fleece by the end of the week as overnight lows fall into the low 40s. Broad high pressure will keep cool & dry conditions for weekend!

     For today & tonight...we start with lots of sunshine today. But clouds are on the increase as that cold frontal boundary edges closer to our area. For now, southwest winds bring in warmer air ahead of the front. things get downright hot today. But rain showers and cooler temps are expected to spread east into our area with frontal passage. Look for breezy conditions, scattered rain and lows near 60 tonight.

     Wednesday the second cold frontal boundary will sweep eastward across the Great Lakes, quick on the heels of the first one. Deeper moisture & cold air along with this system will bring a fall feel & better chance for rain Wednesday night & Thursday. My recommendation: wear pants! Daytime highs will be limited due to cloud cover and rain. Expect highs in the low to mid 60s & lows falling into the mid 40s. A few mountain counties could easily see lows in the upper 30s before the end of the work week.

     A large area of high pressure will build over the breadbasket, stretching into the Mid Atlantic states for this weekend. This will keep dry & mild conditions into the first half of next week. Any tailgaters this weekend will find opportunity to apply sunscreen by late-morning/afternoon. Weekend highs will rebound back to normal but nights will lean towards upper 40s/low 50s.
