Just Getting Started!
With the Summer solstice behind us, this summer is just getting started. Just like clockwork, temps are on the rise. High pressure off the coast is providing for light SW winds which are directing warmer than normal temps into the region. Highs will be climbing into the Lwr-mid 80’s again as the air mass has changed little from yesterday. Dewpoints remain in the 50’s to Lwr 60’s..which is making for a moderately humid day. There is a lag effect from the warmth to the humidity. The heat will come first, then the humidity will arrive Sunday through Monday which will make it a whole new ball game outside in terms of comfort.
A stationary front is in place across the Canadian border help to produce more clouds and scattered showers or a few storms across the north country. Clouds are spilling south even this afternoon. A few of these showers may try to push south tonight for an isolated shower with increasing cloud cover and even low clouds backing in off the water. Patchy fog my try to form overnight with lows falling down to the lwr 60’s
Morning clouds will break to partly sunny skies Sunday with temps and humidity continuing their climb with a huge ridge in place across eastern half of the country with a flat flow to the jetream which will all of for heat wave conditions to develop along the east coast and up through New England. Hot and humid weather will last Monday, Tuesday, Wednesday with a mix of clouds and sun with a slight risk of shower or thunderstorm inland everyday during the afternoon. Any storm could come with a heavy downpour. High will be climbing from the 80’s into the Lwr 90s inland Mon- & Tuesday. Dewpoints should reach the lwr 70’s in this kind of air. Turning oppressive.
A front will finally push through late Wednesday or Thursday with slightly cooler drier air in the 70’s. A deepening trough from the Great Lakes will break down the heat ridge and direct in cooler more seasonal air. Showers will likely be steered into New England with this trough up the east coast. A rainy look to end the week and for the start of next weekend. This trough should persist in the northeast through the July 4th holiday helping to suppress heat and humidity and direct in more comfortable dry air. The heat ridge will likely return back to the northeast after the 7th of July.
