Still looking for a few showers and thunderstorms to bounce through the area before the early-autumn air pours in. Given the slower movement and development, the line of scatttered showers and thunderstorms should arrive toward evening. If any organized line of showers or thunderstorms do come with this boundary then rainfall should be no worse than a half an inch. With the passage of the front, slow clearing in our skies late tonight will be followed by cooler 50s for overnight lows. That takes us to the all important holiday weekend!! Friday's weather will be highlighted by what I like to call a 'windy, temperature downturn'. I happen to hear about it in a Mesoscale Discussion. A deep area of low pressure just north of the Great Lakes is expected to deepen even further allowing for a strong NW to be felt tomorrow. Residual instability in the form of scattered clouds will also develop resulting in some of the coolest air we haven't felt since mid May!! May want to second guess about heading into the pool that day. Afternoon highs will struggle to reach 70 degrees with our hometowns north not reaching 70 degrees at all!! This will lead to a cool start Saturday morning with temperatures in the 40s but with plenty of sunshine..and sunshine is what will be swimming in that blue ocean sky right through rest of the holiday weekend. Afternoon highs are expected around 70 again Saturday but with the wind out of the picture, it should be rather decent early autumn day. High pressure ridge around the Midwest at this time will drift slowly east during Sunday and Monday's outlook. The change we see locally will be in our afternoon highs as a return flow climbs temperatures near 80 Sunday with mid to upper 80s likely on Labor Day. Chief meteorologist James Zahara.
