The week begins a little on the unsettled side with fog and clouds early. Winds will eventually begin to sneak around to the west toward midday and afternoon, which will tend to dry things out a little bit and help to bring a few breaks of sun back into the picture for the second half of the day. However, there's still a weak trough that has to swing through as well, which may touch off a few afternoon showers, especially over central and northern areas. With the aid of any sunshine, temperatures climb back to the upper 60s to around 70°.
Once Tuesday rolls around, the sun will be back out for a long time to come. We shouldn't see anything more than a couple afternoon "fair weather" clouds pop up on Tuesday. Beyond that, high pressure parks itself over the Northeast for several days, keeping skies bright right through the end of the week. Temperatures will stay cool for this time of year through about Thursday, then begin to warm closer to 70° by the end of the week and into the weekend.
