Commuter snow on Thursday ushers in a new round of cold air

A weak weather system will provide some light snow at an inopportune time Thursday morning. Most areas within 25 miles of Boston will see between a coating and an inch or two of the white stuff.

A cold front, followed by arctic, is helping to bring this small round of wintry weather. As that frigid blast pushes out the mild air we've had Wednesdaty, any rain showers in the morning will change over to snow showers. I expect the activity to be over by noon as temperatures fall from near freezing at sunrise to the 20s the rest of the day.

Friday will be dry and cold, with temperatures struggling towards 20 degrees after starting in the upper single digits in the morning. There will be a bit of a breeze, bringing the wind chill down near zero. The next week will feature some of the coldest daily average temperatures we have seen.

Another storm system is likely to pass out to sea safely Saturday night. The western edge of clouds and maybe a few snow showers could make it onto the Cape and the Islands. It's also possible that everybody misses the system completely.

Saturday is colder than Sunday with highs in the 20s. On Sunday, we should be back around freezing. The rest of the month will continue with temperatures at or below average before a potential moderating trend takes hold in early February.
