Summery Day Before The Pattern Change

The areas of fog and low clouds this morning that plague most of Southeast Mass will yield to hazy sun mid to late morning as temps warm up quickly once the sun gets to work.  Highs today reach the mid 80s in the Boston area and upper 80s to near 90 across the Merrimack Valley and much of Southern New Hampshire.  The Cape and Islands will hold in the low 70s with an active southwesterly wind.  The humidity is higher today as well, so it’ll be a summery day for sure. 

As nice it is to have the good beach/pool days on the weekend, we do need rain around here, and tomorrow we start to find it.  A couple of scattered showers/thunder will be around as early as tomorrow morning, but the more widespread action arrives in the afternoon/evening.  Although the whole day doesn’t feature constant rain, when it rains, it may pour.  The atmosphere is loaded with water and as more widespread showers and storm form in the afternoon, there may be a few narrow bands of heavy rain.  Any downpour that hangs around for a while will be capable of producing some localized street flooding.  It’s been very dry lately, so the rivers can handle the water, it’s just that if it rains too hard to fast, the ground doesn’t absorb all that water right away and you get that runoff.  A hard, dry ground also doesn’t initially absorb water well. 

The other thing to note tomorrow will be the temp change.  It’ll be a warm and muggy start with temps warming to 75-80 by midday before falling back into the 50s by dinner time as the wind goes from southwest to northeast! 

We stay cool Monday and Tuesday with a few more batches of showers/thunder rumbling on through.  It won’t rain the whole time, but these batches of showers will occasionally produce heavier rains.  By the time it’s all said and done, many towns from Sunday-Tuesday should pick up 1-3″ of rain.  Localized higher amounts are possible, although the depends on where the narrow channels of downpours form.  Locations of that is tough to pin down now, but may favor areas to the north and west, especially over Central New England.

Anyhow, have a good weekend!
