After some issues this morning with black ice as temperatures hovered near or just under the freezing mark the mercury rebounded well into the 40s this afternoon with a few cities and towns nudging 50 degrees. We have had a nice break this week from the bitter cold earlier in the month but today probably represented the last of the significantly mild days as we start to trend cooler over the next several days.

With the cooler temperatures will come lots of cloudiness with a few periods of light precipitation possible. A couple waves of low pressure move close to southern New England over this weekend. Short term, a weak and somewhat disorganized area of low pressure will pass well out to sea Thursday. This will yield plenty of clouds with a few light rain showers possible in the afternoon and evening. Once this disturbance moves out into the open waters we will be in for another fine mid January day on Friday although not as mild as Wednesday.

Friday night and Saturday one disturbance moves just south of our area and may generate a few light rain and or snow showers. We dry out over Saturday night before another quick moving disturbance brings the possibility of a few snow showers Sunday. We do have to watch out for the possibility of coastal development both days, which would enhance the precipitation, but right now it appears any development would take place too far offshore to impact our area.

Overall, the weekend will feature plenty of clouds with some nuisance showers of rain and or snow but that is about it and should not impact any plans you may have. As noted earlier temperatures will be trending cooler and through the weekend we are going to return to more seasonal temperatures.

Much the same can be said for Martin Luther King Day with a mix of clouds and sun and cooler temperatures.

Tuesday and Wednesday may bring us a more organized system and with much cooler air in place there would be a chance for snow sometime during that time frame. More on that possibility over this weekend.
