The showery rains of Friday into early yesterday ranged from just a few hundredths of an inch over most of Cape Cod to 0.5 to 1 inch over extreme eastern MA to more than an inch from Metro West into Worcester County to 1.5 to 2 inches over western New England. The muggy, wet weather exited just in time to provide us with an absolutely splendid Saturday for so many outside activities including the many college commencements in the region. You know that it was New England May weather at its very best. Boston’s 3:23pm high temperature of 75 was so beautiful and refreshing with the very dry air. The rain cleansed the atmosphere so the pollen count was low in the morning but the main allergens of oak, birch and ash trees will be producing plentiful pollen over the next couple of days.
The water vapor imagery reveals the clear slot that moved over New England yesterday as the ribbon of rain shifted offshore. Several days ago, guidance projected a developing weather block would cause the ribbon of rain to stall over eastern New England as a storm over the Atlantic reversed course closer to the East Coast. Fortunately, that forecast was revised on Thursday and Friday and that made everybody happy for sure. The problem is that blocking will eventually create a spell of wet and cooler weather by late Wednesday into Thursday and Friday this week. Until that completely evolves, a trough of low pressure with some colder air aloft will likely result in patches of developing clouds and perhaps a few spotty showers today, tomorrow and Tuesday. It will not be as stellar as yesterday but it will still be decent. Expect high temperatures in the upper 60s today, middle 60s tomorrow and upper 60s Tuesday afternoon.
Looking ahead, the present prognosis calls for nicer, warmer weather for at least the second half of Memorial Day Weekend. Hopefully, it will be back to 76-80 on those days.
