Metro Boston, North Shore and Metro West: The spring fling we had over the weekend is long gone as much colder air has been overspreading the region. As February winds down Old Man Winter will keep his grip on the Boston area all week with much below average temperatures and the possibility of a touch of snow as well. The bigger weather story this week will be the cold and not the snow.
High pressure at the surface and a disturbance moving through the upper levels on Tuesday should present us with a somewhat similar day to that of Monday. Early sun, afternoon clouds with a chance of a passing flurry or snow shower, especially across the interior. And, it will be cold and windy once again.
The average high temperature around these parts is about 41 degrees this time of year. For the remainder of this week we do not get close to our average high and by Friday temperatures may run close to 20 degrees below normal. There are a couple of chances for snow in the air but it now appears all but certain that the potential winter storm that was being talked about for Wednesday is not going to happen. A weaker system is expected to track well southeast of Nantucket and might bring the northern edge of light snow up to Cape Cod with a chance of a few snow showers or just flurries locally on Wednesday.
Then on Thursday an approaching arctic cold front might trigger a snow shower or two. Once that cold front passes through we go from cold to frigid for the end of the work week as some mighty cold air is going to pay us a visit as we close out February Friday and begin March on Saturday.
There could be another weak disturbance in the area on Saturday that once again may set off a few snow showers or flurries. Then, you guessed it, another shot of arctic cold Sunday.
Although the daylight is extending itself quickly these days it is not going to matter how much sunshine we get on any given day as it appears this cold regime will stake its claim at least into the first part of next week as well. And, more potential for snow comes with the cold for next week.
