While the next few days will be anything but quiet around here, we’re not expecting anything extraordinary in the weather department either.
Low pressure will move up the St. Lawrence Valley on Friday. As is usually the case when that happens, we’ll have somewhat milder air move in along with some light rain. However, temperatures will still be cool enough that the rain may start as snow north and west of Boston if it moves in by midday. As the milder air takes over, the snow should change over to rain, but there may be enough snow to coat the ground in spots. We’re not expecting a lot of rain, nor are we expecting a big warmup, so don’t expect much of the snow from the storm earlier this week to melt.
High pressure builds in behind the system for Saturday with some sunshine returning along with seasonable temperatures. The latter half of the weekend is where things get tricky. We’re watching two pieces of energy, one in the northern jet stream and another to the south. If these two were to meet up, or “phase”, we could end up with a big storm. Some of the models were hinting at that possibility earlier in the week, but it looks a lot less likely now. What is more likely to happen is that the southern system starts to develop but passes well south of the region, possibly delivering a little light snow to parts of the South Coast and maybe a little farther northward. The northern system will swing through here with some flurries or snow showers. Overall, not a big deal for most of us. Parts of the South Coast could see a few inches of snow depending on how far north the ocean storm actually gets, but otherwise, we’re not anticipating much accumulation across the region, unless things change in the next day or two.
As we head into Monday, high pressure start to build back in with drier and colder weather. While it is likely the start of a colder pattern overall around here, temperatures will only be a little below normal for early February. The bulk of the cold air will stay well to our west. In parts of the Northern Plains and the Canadian Prairies, temperatures will be as much as 35-45 degrees below normal this weekend, with some areas dropping to 30-40 below zero at night, and daytime highs only in the -10 to -15 range. Wind chills will be colder than -50 in parts of the region.
