More Dry Than Wet
Posted by Chris Lambert
As we roll into the first weekend in August, the weather looks like it'll work out for the most part. Every once and a while, a passing shower or storm runs on through, but many of the hours both on Saturday and Sunday look dry.
We'll track an isolated shower or thunderstorm this evening as some energy from Upstate New York slides on in. The best dynamics to spark that passing shower or storm is in the 7-10PM timeframe with the earlier part of that timeframe in Worcester County, and the later half of that timeframe closer toward the coast. Not all of us see it though, by isolated, I'm looking at about 20% of us getting hit.
Another batch of energy in the atmosphere arrives first thing tomorrow morning with a front. The timing of the front coincides with the coolest part of the day, so showers and storms will be limited. About 30% of us get with with a morning shower Saturday before mostly cloudy skies yield for partial sun. The late morning and afternoon hours look good with temps running in the lower 80s.
Sunday starts dry and that dry weather holds until mid to late afternoon. By the warmest time of the day (3PM) a few pop up showers and storms develop thanks to cold air aloft provided just enough instability. About 20% of us get hit, with the higher threat the farther north and west of Boston you go. The Cape looks unlikely to get hit Sunday afternoon, although, down there, an early morning shower is not out of the question. Highs overall on Sunday are cooler, in the upper 70s.
Monday is an even cooler day. Mid 70s for highs with sunny to partly cloudy skies. With such a cool air mass in place, temps tumble Monday night with Tuesday morning lows around sunrise in the upper 40s in the suburbs! Now that's early Fall material!
Have a good weekend.
