It’s mild today, but a messy Friday is on the way.
A strong cold is making its way toward the region this afternoon. We’ll have some rain ahead of it tonight, and the rain may be quite heavy. The combination of rain and mild temperatures will help to melt a lot of the snow that remains from last weekend’s blizzard. The front moves through this evening, and colder air will slowly make its way into the region early on Friday, first at the surface, then aloft. As temperatures drop, the rain will change to freezing rain and then sleet from north to south. With the roads already wet from the rain and temperatures dropping, a flash freeze is likely, and it will unfortunately be timed for the morning commute. If you’re going to be out in the morning, use plenty of caution, as untreated surfaces will become very icy quickly.
Temperatures will continue to drop during the day, with the freezing rain and sleet likely ending as some wet snow, mainly north of the Mass Pike. Everything winds down in the evening, then skies gradually clear out at night as high pressure builds in. This sets up a sunny but cold Saturday across the region. The high slides off to the east for Sunday and Monday, keeping us dry, but allowing temperatures to begin to moderate once again.
Thursday night: Rain, possibly heavy at times, changing to freezing rain and sleet late at night, mainly across southern New Hampshire and northern Massachusetts. Low 26-33 north of the Mass Pike, 34-44 south of the Pike.
