Cool Weekend…Mild Midweek
Pretty straightforward forecast as we have saying the past few days. Unseasonably cool weather here to stay for the weekend with Canadian High pressure sitting right over us. Plenty of sunshine out there today with high thin cirrus clouds drifting above our heads. A trough to our west will be pushing into the region this afternoon bringing a few thicker middle level clouds along with it. High pressure at the surface will keep us dry and cool with highs in the mid 60′s for most. Winds will be light, so a PM seabreeze will keep temps mainly in the lower 60′s at the beaches.
A little short wave will be pushing through tonight, accompanied with a few clouds. A quiet cool night in the 40′s, but not as cool as last thanks to increased cloud cover. This trough will help an area of low pressure to come together off the mid-Atlantic coast. High pressure over New England will keep this well south of us. The low will strengthen, which will create a tighter gradient between the high and the low, which will allow winds and surf to pick up Sunday into Monday especially at the coast, primarily the Cape and the Islands.
High clouds will still be in place Sunday morning but will erode away with increasing sunshine for the afternoon with temps still in the mid 60′s on average with East winds at the coast. Clouds breaking off the low to our south which may linger on the Cape & Islands Sunday…brilliant blue sunshine developing in most locales. Ridging behind the departing trough will help the departing surface high to reassert itself providing another fine day into Monday. Still winds will remain breezy out of the east with temps in the 60′s
A weak front approaches Tuesday with the risk for shower or two during the morning. It falls apart over us, but more clouds with slightly warmer temps near 70 will be in place. More upper level ridging on the east coast with SW winds will bring a warmer and dry Wednesday into the mid 70′s. A strong trough will be pushing south into the Great Lakes and we will be tracking a cold front moving east in the Thursday-Friday time frame providing the chance of showers. Behind this front building high pressure moves in for the first weekend of fall with a cooler less humid feel. A trough will remain inplace across the northeast for the rest of September which will keep temps running below normal. It does not look like we have much of a chance to warm up until October…and once we get there..well…we just start to run out of time. As it is with the change of seasons here in New England, “Love the one you are with” always seems like an appropriate song to get by. Gotta love this weather!
