Metro Boston, North Shore and Metro West: Last week presented us with many ups and downs with wild temperature swings and periods of snow and rain. This week will begin plenty cold but overall the pattern is quiet through mid week. High pressure stays in place over the next few days allowing dry conditions and unseasonably cold temperatures. It is this high that has kept the storm impacting the mid-Atlantic region to our south last night and today. The next chance for precipitation comes along Wednesday night and early on Thursday as a cold front moves across the area.
It was mentioned yesterday that temperatures through the first half of this month have been over 5 degrees below normal which is no surprise. We can tack on to those numbers given the temperatures Sunday and more unseasonably cold weather into early Wednesday. As one of my readers informed me recently, at least we don’t have to shovel the cold. Temperatures Monday will run 15 to near 20 degrees below normal, not quite as cold Tuesday, but still well below normal, then nearing our seasonal average Wednesday.
With the departing ocean storm to our south the northern edge of its cloud shield will begin to retreat from northwest to southeast during Monday. We should be mostly cloud free Monday night through Tuesday night before more clouds arrive Wednesday ahead of an approaching front.
Low pressure moves into the Great Lakes Wednesday and well to our north Thursday, swinging a cold front through here early Thursday. The air mass behind this front will not inject a shot of much colder air. Most likely temperatures remain close to seasonal averages. With the approaching front there is a chance of rain and snow showers Wednesday night into Thursday.
High pressure brings a return to drier conditions later Thursday into Friday.
Three Day Outlook:
Monday: Mostly cloudy early with decreasing cloudiness from northwest to southeast. Partly sunny through the afternoon. Continued cold. High temperatures in the upper 20s to 30 degrees. Brisk northwest winds in the morning becoming north at 8 to 15 mph.
