Quiet Weather Expected This Week; A Slow Moving Storm May Bring Mixed Wintry Precip This Weekend

For The Rest Of Today: Plenty of sunshine is expected throughout the rest of today with high temperatures between 25 and 30 Degrees. Northwest winds will gust up to 25 mph at times today.

Tonight Through Tuesday: An area of high pressure will move from the Central United States tonight to the Central Appalachian Mountains on Tuesday. A northwesterly wind flow on the northern side of this high pressure system will bring continued cold weather to Western and Central Mass tonight and Tuesday.

Tonight will be clear with low temperatures between 5 and 10 Degrees.

Tuesday will be sunny to partly sunny with high temperatures near 30 Degrees.

Wednesday Through Friday: A large high pressure system will control our weather on Wednesday, Thursday and Friday. This means that the weather will not only remain dry and quiet, but also temperatures will warm up.

Wednesday is expected to be sunny with high temperatures near 35 Degrees.

Thursday will be sunny with high temperatures between 40 and 45 Degrees.

Friday is expected to be sunny to partly sunny with high temperatures between 39 and 43 Degrees.

Possible Long-Duration Storm For This Weekend: There continues to be strong signals in the long range weather data that suggest that a coastal storm system may impact Western and Central Mass this weekend. Please remember though that this is still a possible storm that is 5 to 6 days away and there is considerable uncertainty as to the exact track of this storm, as well as what type of precipitation may occur and how much.

The one thing that I can say is that the initial air mass at the beginning of the storm will be relatively mild for January standards, so I’m extremely hesitant to go with all snow with this storm as I think we may see ice and rain mix in throughout the storm. With that said, it looks like we will see a high pressure system over Atlantic Canada and northern Maine. Depending on this high pressure system’s exact position and the exact track of the possible coastal storm system, there may be just enough cold air drawn into the storm so that we may see a messy wintry mixed precipitation event consisting of snow, sleet, freezing rain and rain.

In addition, this could be a slow moving storm system that could bring a long-duration mixed wintry precipitation event starting around midday Saturday and continues through Saturday afternoon, Saturday night, Sunday and possibly part of Sunday night.

It’s also important to note that there is A LOT of potential with this storm this weekend. The weather forecast guidance I look at to forecast seems to be currently trending towards a stronger high pressure system over Atlantic Canada, which would cause more cold air to be drawn into the storm. The weather forecast guidance is also trending towards a slower moving storm system, which could prolong this storm across the area. At this point though, pretty much everything is still on the table for scenarios, including an all snow event to a mixed sloppy mess of snow, ice and rain to even a snow to start with that changes to rain scenario. For now though, I think that we probably wont see an all snow event & at the same time, I also think that we probably wont see an all rain event either. I think, instead, we'll see a "kitchen sink" type storm that throws everything at us, including snow, sleet, freezing rain and rain on Saturday afternoon, Saturday night, Sunday and maybe part of Sunday night.

Keep checking back for the latest updates on this possible weekend storm as I will be posting a new update at least once a day throughout this week.
