We’ll start the week with some great weather, but it may not end that way.

We start the week with nearly ideal conditions for Patriots Day – mostly sunny skies, lighter winds, and temperatures that are 5-10 degrees above normal. It might be a tad warm for the Marathon runners, but for everyone else it’ll be fantastic for outdoor activities. Tuesday is shaping up to be a similar day with more sunshine and mild temperatures with high pressure still in control. Wednesday is when things start to change. A low pressure system that will produce severe weather across the nation’s mid-section over the next couple of days will head towards the Great Lakes, sending clouds our way. With high pressure off to our north, we’ll remain dry for much of the day, but winds will become onshore, so it will turn much cooler along the coast, though it will remain fairly mild once you head farther inland. A secondary low pressure system will begin to develop across the Mid-Atlantic states late Wednesday, passing south of the region Thursday, with some showers expected. Friday may end up being a dry day with that system meandering around well to the south. A cold front brings in some more showers for Saturday, then it looks like high pressure will build in with dry weather for Sunday.
