Looking Ahead...
Well very little has changed since this time last night and very little will change over the next two days. We are still under the influence of the storm system which is to our north now and will migrate to our east tomorrow. It is being fueled by a cool pocket of air several thousand feet up this creates a very unstable atmosphere. When the sun comes out in the morning it heats up the ground and the air right above it...that air rises and cools and condenses into clouds...those clouds build in the sky and release rain showers. Normally those rain showers would reach the ground and give us an ocassional soaking but the air is so bone dry that these showers are evaporating before reaching the ground...this is known as virga. The storm system will swirl away from us on Friday leaving a nearly perfect day for the Red Sox home opener with lots of sunshine and mild temps near 60 degrees.
Over the weekend, high pressure will slide to our SE this will pump warmth into New England...SW winds will shoot temps to 65-70 on Saturday. The leading edge of Summer-like air will work in Saturday night kicking off a few rain showers. The showers will exit first thing Sunday morning, the sun will pop out and temps will pop up close to 80 perhaps!
The big question is will the heat break for Marathon Monday and the verdict is mixed. Presently, it appears that a cooling front will get hung up in the area just south of us this will mean that the heat will be diffusing likely peaking in the low to mid 70s by the end of the event. If this front realigns itself a bit it could mean a big temperature shift...farther south of us, much cooler...farther north of us, much warmer. If I had to lean one way or the other I would not side with the much warmer and hedge cooler.
