An unsettled and cool week is ahead as we will find ourselves in the midst of a battle between warm air and cold air. A nearly stationary frontal boundary will set up shop over New England for most of the week and it will be wobbling north and south with waves of energy moving along it bringing rounds of precipitation. Most of the activity will be light, but there will be a couple of stronger circulations coming along in that flow, especially late Tuesday and again on Friday.
For most of southern NH each round of precipitation that comes through will be mainly rain. Throughout the CT River Valley and the Lakes region it will tend to lean toward mainly rain, but wet snow can mix at any time, especially at night. From the White mountains northward the precipitation events will tend to favor snow and in fact the mountains themselves will pick up several inches of snowfall this week!
Scattered rain and snow showers develop early Monday and lift northward during the day and then become more prevalent into Monday evening. As the rain changes to snow up north it looks to leave a coating to an inch Monday night.
A more organized Low pressure center will move through late Tuesday bringing primarily rain with it. However, north of the Lakes region snow will be mixed in with the rain and far to the north rain changing to snow. Again, accumulations likely for the north country with 2-4 inches in the higher elevations and mountains. Rain and snow showers taper off during Wednesday and Thursday should basically be a dry day.
Another storm system will move through for Friday perhaps bringing some heavy rain, so we will need to watch that one as it could help lead to small rivers and streams coming up to bank-full combined with snowmelt during the week.
