A weak low pressure will continue to move north out of the region today and tonight creating mostly to partly cloudy skies with a slight chance of a shower northern locations. Low Temperatures will be in the 30s for the week. Skies will clear and will become mostly sunny for the rest of the week with highs in the 50s. An area of low pressure that will give the Northern Plains their first major snow storm of the season will travel north of the region, a secondary low pressure will form over our region interacting with the parent low pressure and looks to be reabsorbed by the pareoknt low at this time. Rain will develop for Sunday and will last through Sunday night. There is a chance of Rain changing to a mix of rain and snow Sunday night. Due to a blocking pattern the low will get trapped up in Northern New England/Southern Canada and will spin creating the chance of rain and snow showers through Monday night. No accumulation is expected at this time across the Merrimack Valley but some of the Mountains could see some. If the secondary low becomes more dominate, we could be talking more rain and a better chance for a switch with higher snow amounts for Northern New England. Temperatures will be in the upper 30s to mid 40s for the beginning of next week.
