Another chilly week is expected, but trouble could be lurking next weekend.
A dry, but chilly day is expected today as high pressure builds in, but it won’t stay that way for long. An Alberta Clipper will be heading this way, sending clouds back in late today, with some snow showers late tonight into early Tuesday. Temperatures may be marginally warm enough to change the snow to rain across Cape Cod and the South Coast. Any accumulation should be an inch or less. Once that system moves by, high pressure builds back in for Wednesday and Thursday with much colder weather once again. Another weak system may bring in a few snow showers on Friday as temperatures moderate a bit. This brings us to next weekend.
For several days now, the models have been indicating the potential for a significant storm system somewhere near the East Coast around Saturday, January 29. We’ve mentioned more times than we can count that the models aren’t trustworthy beyond about 2 or 3 days right now, but they have all had the same signal for quite some time, which gives us increased confidence that there will be some sort of storm, and it will probably be potent. However, models are showing little consistency beyond that in terms of how strong it will be, where it will track, what areas (if any) it might impact, and what impacts (if any) that it will have. At this point, everything is on the table, from a swing and a miss with the storm heading out to sea, to an inland runner, where we end up on the warm side with heavy rain and mild temperatures, to a mix of snow, sleet, freezing rain, and rain with the storm tracking right over us, to a full-fledged blizzard with the classic track right up the coast. Depending on which model you look at, and which run of that model, they have all indicated any and all of these scenarios at one point over the past several days. So, at this point, it is impossible to make a forecast, because frankly, we just don’t know, and probably won’t have a better idea of what to expect until at least mid-week. By the time we issue our Weekend Outlook on Thursday, we *should* have a decent idea of what will happen, but even that isn’t definite. So, stay tuned….
