Metro Boston, North Shore and Metro West: While areas to our west got pounded by heavy rain and severe weather early this week the coastal plain stayed mainly dry and quiet. Even areas just west of Route 128 and especially across the Route 495 belt saw some heavy activity Monday and Tuesday with severe weather causing damage in some locations there. With the axis of precipitation shifting eastward Wednesday it was a sure bet the coastal plain would finally receive its share of heavy rain during the day.
Mother Nature did not disappoint as areas throughout the metro Boston area were hit hard with torrential downpours that flooded low lying areas and wreaked havoc on the roadways during the afternoon. Commuters were dealing with flooded roads that in some cases were impassable. Route 128 in the Waltham and Woburn stretches was down to one or two lanes during the deluge with commuters along Route 1 in Saugus experiencing much the same. The showers became less intense and more spotty as evening approached with some very impressive rain totals throughout the area.
As of about 6 pm last evening Belmont reported 2.73 inches, Stoneham received 2.35 inches, Wakefield 1.60, Saugus 1.33, Rowley .97, Beverly .82 and Newburyport .79 with many other communities receiving over an inch of rain throughout the forecast area, especially just northwest and north of Boston. Other areas south of Boston, across the southeast portion of the Bay State and Cape Cod also received a good drenching on Wednesday as well.
The cold front that was advertised to bring a change of air masses has slowly moved to a position across Cape Cod during the overnight and is expected to continue its journey into the western Atlantic before stalling several hundred miles offshore. This will introduce a much drier and refreshing air mass during Thursday and especially so on Friday allowing us to turn off the air conditioners for a couple of days or so.
Expect thinning clouds early today followed by a good amount of afternoon sun. High temperatures around 80 degrees. Humidity levels become much more comfortable as the day wears on. Light northwest winds, becoming onshore along the coast during the afternoon. Temperatures cool down to a very comfortable upper 50s across most sections to about 64 in Boston during the overnight. Winds fall off to near calm.
High pressure expands eastward and across southern New England Friday and Saturday. Fair skies, low humidity with daytime highs in the low 80s inland, mid to upper 70s on the shore. Nighttime lows in the mid to upper 50s inland to low 60s on the coast.
Low pressure moves along the stalled frontal boundary well offshore but may come close enough to spill clouds into the area on Sunday. Lets call it a partly cloudy day for now with afternoon highs into the low and mid 80s. If the disturbance inches closer to us then expect more clouds than sun.

Thursday: Early clouds to be followed by a mostly sunny afternoon. High temperatures about 75 degrees with much less humidity. Light winds becoming onshore in the afternoon. High tide about mid afternoon. Water temperatures in the mid 60s. UV Index high.
