Forecast discussion: It has been a while since Southern New England has seen much precipitation. Right now, the upper levels of the atmosphere do not support much in the form of developing storms. In fact, a very strong high pressure system over eastern Montana is providing about 90% of the entire country with dry weather at the moment. However, as we move towards the end of the weekend, we will be seeing more rain, with the risk of some wintry weather.
For now, this strong ridge will bring sunny skies but colder temperatures. Overnight lows will be in the middle teens, while turning slightly warmer Wednesday night. If you happen to be outside for any midnight festivities, expect clear skies and a temperature of 25 degrees when we begin 2015.
The calm weather will continue right through into the daytime hours of Saturday. By this time, a low pressure system over eastern Texas will begin to bring increasing clouds over the region Saturday afternoon. Due to the cooler temperatures, the precipitation may begin as sleet or freezing rain. However, as we move into Sunday, warmer air will arrive, changing the precipitation to all rain. It appears the cold front will pass through early Sunday afternoon, with the showers coming to an end no more than a few hours later.
A new high pressure system will bring sunny skies once again as kids head back to school after their long holiday vacation. But, temperatures will still remain slightly below normal, with high temperatures only in the middle 30’s.
