partly cloudy skies but there are building clouds up through the gulf of maine and the bay of fundy. ironically high pressure which has given us sunshine will start to pull this clump of clouds down out of the gulf of maine and into southern new england overnight tonight and through the day tomorrow. so, temperatures tonight will actually bottom out in the lower 20s and rise to the upper 20s and the low 30s with a couple of pockets of drizzle but it doesn't take much to foul up a morning commute. but the numbers tomorrow morning right around 29, 30 degrees in metro rest. route 2 corridor, so just be mindful of that early tomorrow, nashua tomorrow morning around 30. boston 33 and similar depend on saturday morning, this pink shading not to say everyone is going to see it but those will be the locates there may be a little patchy freeze. i think metro boston plain old drizzle.

boston tomorrow around 39. norwood at 36. plymouth at 40. cape ann, merrimack valley numbers running in the upper 30s to around 40. worcester hill as slower process to have the temperatures move all. on the cape and the islands mashpee 41. provincetown at 40 degrees. so this is the next couple of days. here is our next real weather player if you will. area of low pressure in missouri and this will be a potent weather system that heads to new england and west of new england. when these storms go to our west, they essentially boot out any cold air. so we're talking about rain heading this way. not snow. not ice, this is sunday. here comes a warm front. a good chunk of rain and even wind on the day on sunday. the amount of rain on the way, i think most of us will pick up about an inch of rain. maybe a little more up through the merrimack valley aswell as the worcester hills and also windy conditions, winds on the islands on sunday maybe

at this. this is not a nor eater. it's a south eater. warms up. the record on sunday for boston is 56. worcester it's 53. i think we're heading for the lower 50s. 7 on 7 forecast behind that storm, here comes the cold back into new england. blustery and cold monday and tuesday, snow lovers, not your time but i have a couple of flurries possible middle of next week. see you at 5:30. >> ryan: a close call for a group of fishermen who came very close to being impaled by their big catch. >> kim: the big jackpot didn't go but someone got a pig tickets in plymouth. >> ryan: we will have the latest on the breaking news out of north andover. explosion at the dow chemical plant. four people hurt. a very active scene.
