Temperatures Should Cool Off Later This Week

Since last June, the Upper Valley has seen a number of daily high temperature records fall.  The unusual weather has continued into the winter as well, with arctic air chilling the Lower 48, and warm air from the Pacific heating Alaska up.  Monday marked another record high, as the temperature reached forty-five degrees.  Looking ahead, however, the forecast is calling for temperatures a little closer to normal,  potentially dropping into the single digits by Thursday night.  Precipitation is also expected to taper off as the week goes on.

The reason for the shift in weather is that the high pressure system that has kept the warm, moist air here is beginning to weaken.  According to forecasters at the Anchorage office of the National Weather Service, a low pressure system has started to eat away at the high pressure ridge over Alaska.  That means that warm air will once again begin to escape, and cooler air will take its place.  While it has been a week for light layers and mud boots, it looks like winter is not done after all.
