Spring can have long cool unsettled period,but this usually happens in April or early May.A strong -NAO is setting up this week,which set up blocking out in the Atlantic.What this does is create an upper low which sit and spin over the great lakes,which will in turn send various troughs and lows up along the east coast,and bring cool atlantic moisture.
To start off a cold front will sweep through tomorrow bringing heavy rains for most of the day,severe weather could occur in NY,Penn. and mid-atlantic which will be in the warm sector of this system.It should dry out somewhat Sat. night and Sunday,then the upper low takes over for most of next week,with a strong low pressure forming east of New England which may turn into a gale system spinning in showers and windy conditions off the cold atlantic.Does not look like nice stretch of weather through next week,so June will start out much below normal.May continued the string of above normal weather, finishing a little over 3 degrees above normal.
Although June looks to start out below normal,long range indicates we should get back into some warmer weather by next weekend and beyond.We;ll have to wait and see.
