Cool Feel For Weekend...Looking for Midweek Warmth
Clouds will start to spread into the region Sunday afternoon, and even the risk of a slight shower is possible by the afternoon. But really, Sunday is looking fine with similar temps to Saturday, still mid 60's coast , near 70 inland. The cooler onshore winds will linger into Monday, but weak high pressure will provide the subsidence and sunshine. A trough just offshore will keep temps seasonably cool through the beginning part of the week. It also looks like a pretty dry pattern with only slight risks of a few chances of showers for the week ahead.
Currently, there is a huge heat ridge over the mid west and southeastern states where temps are soaring into the 90's to near 100 degrees this afternoon. Summer is on! The warmth can not spread east thanks to a developing negative NAO. With a high over Greenland, a blocking pattern is slowing the pattern and we are on the cooler side for now. As the trough lifts mid-late week, this heat ridge should begin to flatten and shift eastward towards the east coast allowing some warmer more humid air to develop..
850 mb temps will be warming to 16-20C which would allow temps to climb into the 80's to near 90 if the air can mix down by Wednesday & Thursday
Some models are keeping it a bit cooler with the warmer air staying south and way in the negative NAO. Either way, it does not look very wet. Much of this week will be on the dry side. Temps should be able to climb well into the 80's with SW winds in southern New England Wed & Thursday. We will have to watch a frontal passage sometime around Thursday. This will be our best chance for a shower or T' storms. Warm and humid ahead of the front with cooler drier air returning for the end of the week into next weekend with air back out of Canada and the ocean. Next weekend should be a beauty with Canadian High sinking south into New England.
The tropics may be coming to life this week in the Carribean. A tropical wave may be approaching Florida for the midweek.
