A cold front has passed off the coast leaving a cool, but dry air mass in the area for the rest of the weekend. There are clouds and even a few showers pushing off the coastline early this morning, but clearing is coming and by this afternoon sunshine will be the dominate weather feature. It won’t be very warm with highs in the upper 60s to lower 70s here in southern New England. It will be cooler over Cape Cod.
Clear skies tonight along with light winds means the atmosphere will be able to very efficiently get rid of the heat that builds up this afternoon. This time of year the nights are very short and there isn’t much time for the temperature to fall. This is a good thing. If this was even a month ago there would likely be enough darkness to bring a more widespread frost to the region tomorrow, but with just under 9 hours between sunrise and sunset temperatures will stay out of the frost range for most of us. The one exception is western Maine and northern New Hampshire where a frost advisory is posted and folks might want to cover their tomatoes etc. in those spots. (areas in blue below)
Sunday is my pick of the weekend. Light winds and nearly 100% of the possible sunshine will make it an ideal day to be outside. It won’t be very warm, especially to start the day, but by afternoon the sun will have heated the ground and in turn the air enough to make most outdoor activities a pleasure.
Another frontal system brings back the clouds and the chance of showers to start the work week. Presently it looks like a quarter to three-quarters of an inch of rain will fall during the period from Monday to Tuesday. I’ll be more precise about the timing in the coming days, but wet roads would likely impact at least one or two commuter cycles.
It’s not snow of course, but it does seem any precipitation just slows things down.
The middle of the week appears to be warm and dry with temperatures reaching the 70s and 80s. As usual, it will warmest inland where the mid-80s is possible.
An early look at next weekend shows the models conflicted whether or not a front (boundary of air masses) will be stuck close by and bring clouds and showers or push far enough away to leave us dry. While this isn’t much help in planning next weekend, it’s all I have right now and my confidence and accuracy are both low this far out.
