A cooler wind will come rushing in on Wednesday...I know it's not Frank Sinatra, but it will still be a nice day...just about 20 degrees cooler that Tuesday! Wednesday will start off with sunshine in the morning with a building afternoon clouds. Temperatures will struggle to warm with cold air advection being directed into New England upon NW winds gusting 20-30 mph. Highs will hold in the lwr-mid 60's with mix of sun and clouds. The best chance of a shower or sprinkle will be in the northern mountains.
Skies will clear later in the afternoon and give way to clear and cool evening. Most areas will stay above freezing Wednesday night, but a few of the coldest locales across the mountains and northern valleys could see a touch of frost early Thursday morning. High pressure will slide down with wall to wall sunshine, lighter winds and highs in the 60's to near 70. Moderating temperatures will continue Friday with high pressure sliding south of the region, warmer west winds will help highs to climb to 70-75 Friday with increasing high altitude clouds.
The weekend poses a challenge as a warm front will approach Friday night into Saturday. This will spread in clouds along with the risk of a few showers Saturday. A wave of low pressure will track along this front and well south of the region. As it pulls away, cool onshore winds will be reinforced Sunday into Monday, along with the risk of low clouds being trapped in over us. So there is some uncertainty how this weekend will play out in terms of sky cover and temperature. Sunday and Monday are looking dry, and if the clouds lift or break and allow for some sunshine, temperatures will be warm in the Lwr 70's. If not, and we are dealing with more clouds...well we should expected cooler temps in the Lwr mid 60's..if that.
Another front will approach Monday night into Tuesday which could trigger a few more showers. At this point of the game, we need to get as many showers as we can get because it is so dry and does help to alleviate some of the crazy pollen levels which are currently in place. The Climate Prediction Center does show a warmer pattern developing in the eastern half of the nation from the 18th to the 22nd...but I have a feeling some of that warmth may struggle to fully be in place across New England...if this weekend is any clue...
