At around 100 miles per hour, a wild storm system moved rapidly through the middle of the country Wednesday, pushing near record highs into Southern New England for the day today.
It’s worth noting that this weather system brought winds in excess of 75 mph to over half a dozen states out West, and tornado warnings were out for the Midwest Wednesday evening. The air that is arriving here today brought new all-time December high temperature records to spots in the middle of the country.
As the storm continues to push up into Canada, a slug of air 20 to 40 degrees above average will move into the eastern part of the United States. At this time of the year, temperatures should be in the upper 30s to lower 40s in Massachusetts, but we’re going to see readings in the middle 60s in greater Boston on Thursday.
The record high temperature for Dec. 16th is 64 degrees in Boston and 58 degrees in Worcester. Both of these records were set in 1971, and there’s a chance that they will be tied or broken. Sunshine will be key Thursday afternoon to just how warm it will get. The more sun, the better chance of new records, even some in the upper 60s.
There’s likely going to be several hours where conditions will feel somewhat spring-like Thursday, after a few morning showers.
A cold front will cross early Friday, but it’s not going to become that chilly, with readings on Friday in the 50s along with more sunshine. I think Friday will be the final day this year when you’re going to comfortably be able to be outside, do some yard work, and generally not have to bundle up.
A weak weather system will cross through New England on Saturday and into Sunday. There is going to be enough cold air in the system that there will be snow on the northern flank, a mixed bag in the middle, and rain along the coastline and to the south. This does not look like it’s going to be a big storm, but in areas that will see all snow, there could be enough to get the plows out. Snow and rain break out late morning Saturday and end early Sunday.
The sky should clear later Sunday and temperatures will be seasonable. That may feel cold and unusual, but that’s only because it’s been so warm this month. The rest of December will feature temperatures at or even a bit below average for most days.
