Metro Boston, north shore and western suburbs: The arctic air still has a pretty firm grip on the area today as temperatures started out in the single digits across the area and have struggled to reach the low to mid teens by midday. Gusty winds have kept the wind chills zero to at times 5 below through the morning. This will be the last of the much colder than normal days as temperatures begin to moderate late week and this weekend.
High pressure will bring fair skies with a good amount of sunshine into Thursday. The cold will slowly retreat this afternoon and more so on Thursday with the winds easing some as well. Although temperatures still remain below normal through Thursday it will feel a whole lot better than the blustery conditions since Monday night. A weak disturbance in the upper levels will bring some clouds our way tonight but no precipitation is expected.
By Friday skies turn mostly cloudy as the high moves offshore and gives way to an approaching disturbance coming out of the Tennessee Valley. This system is not going to generate much precipitation locally, if any at all, as it slides out to sea south of us. Perhaps a few snow showers or flurries overnight but that is about it. Temperatures continue to slowly moderate.
Saturday, a cold front will approach from our west. Ahead of the front winds begin to increase out of the south and this will bring in more moisture and mild temperatures. So, there is a chance of a few showers Saturday with the shower activity more likely Saturday night into very early Sunday morning. There could be a few locally heavy downpours overnight and winds become gusty, this time out of the south, Saturday night.
The cold front passes through early Sunday and skies partially clear with a mild day ahead. The air mass behind this next cold front will not deliver anywhere near the kind of cold we have seen recently with the arctic fronts, although it does turn a bit cooler for the start of next week.
If you are attending the New England Patriots game Saturday night at Gillette Stadium the early prediction is for showers in the area and mild with the temperatures in the 40s.
