Heavy Rain Late Tonight & Saturday Morning: A robust low pressure system is expected to head into Quebec, Canada later tonight and Saturday. This will pull a strong cold front across our area during Saturday morning. Rain is expected to overspread Western and Central Mass around midnight tonight and continue right through all of Saturday morning. A period of heavy rain with the possibility of a thunderstorm or two is expected between about 4 am and 10 am Saturday morning. The exception to this will be across the northern Worcester Hills, the Berkshires and across areas north of Route 2. These areas are likely to begin as snow around midnight tonight with the snow for several hours late tonight before changing to rain around sunrise Saturday morning. Rain, heavy at times, is then expected across these areas throughout Saturday morning. Snowfall amounts late tonight will range from 1 to 3 inches across the northern Worcester Hills and the hilltowns of the upper Pioneer Valley to 3 to 6 inches of snow accumulation across the Berkshires. Rain is expected to come to an end during the first half of Saturday afternoon. Total rainfall amounts from late tonight through Saturday morning are expected to range between 1 and 2 inches across all of Western and Central Mass. Maybe A Quick Burst Of Snow Saturday Evening: One last piece of energy with the storm system may bring a quick burst of snow to the entire area between 7 pm and 2 am Saturday night. Any snow accumulations on Saturday evening should amount to a light coating across most of the area. The exception may be across the Worcester Hills where a quick inch or so of snow accumulation is possible. Weather Outlook For Next Week & The Following Week: As has been expected since late December, it looks like Western and Central Mass will head towards a colder and potentially snowier weather pattern starting next week and continuing through the end of this month and through the first week of February. High temperatures next week will average between 30 and 35 Degrees every day with low temperatures next week averaging between 18 and 23 Degrees every night. These types of temperatures are likely to last through the following week (week of January 25). As for snow chances – A weather disturbance passing across the region may bring light snow to the area late Tuesday night and Wednesday morning with maybe an inch or two of snow accumulation possible. Beyond this, an area of low pressure could form near Nantucket next Friday leading to the potential for accumulating snow on Thursday night and next Friday morning. This should be a quick moving storm system, so a heavy snowfall looks unlikely and more than likely would end up being a 2 to 4 inch or 3 to 6 inch snowfall. Looking even further ahead, we might have to watch around January 25 or 26 for a coastal storm that could bring the area accumulating snow and then again during the weekend of January 30-31 for another chance for accumulating snow. Bottom line is that above average amounts of snowfall look quite possible across the entire area for the next 3 to 4 weeks. How much above average remains to be seen and depends on the exact track and dynamics of each of the storms we are watching. I will mention that long range guidance is forecasting a total of between 25 and 35 inches of snow total between now and February 28 across the entire area. If this ends up true, then it would be about 10 to 15 inches above average for snowfall.

This Afternoon: A weak area of high pressure will control our weather this afternoon. Cloudy skies are expected this afternoon, but it’ll be dry with high temperatures between 38 and 42 Degrees. Tonight: Generally cloudy skies are expected tonight, but again it is expected to be dry. Low temperatures tonight will be near 20 Degrees. Wednesday: Generally partly sunny skies are expected throughout Wednesday with high temperatures near 40 Degrees. Thursday Through Friday: Quiet weather is expected to continue through Thursday and Friday. Thursday is expected to be partly sunny with high temperatures near 40 Degrees. An increase in clouds is expected on Friday as a frontal system approaches the area from the west. High temperatures Friday will be near 45 Degrees. Rain Is Expected Late Friday Night & Saturday: A robust frontal system is expected to push across the region later Friday night and Saturday. This front will pull some very moist air northward into the region. In addition, a secondary low pressure system is expected to form near eastern New England leading to a little more energy input into this frontal boundary. What all this means is that a soaking rain is expected across the entire area beginning just after midnight Friday night and continuing through much of the day on Saturday. Rainfall amounts of 1 to 2 inches are expected across all of Western and Central Mass. When Is It Going To Snow Again? I still think that the last 10 days or so of this month will feature below average temperatures. In addition, the weather pattern continues to look favorable for Eastern United States storminess and we’ll be watching for at least a couple of chances for accumulating snow between January 20 and January 31. At this point, it’s too soon to really pinpoint exactly what dates and how much snow may accumulate, but I’m watching 3 time periods with particular interest - January 20-21, January 23-24 and finally January 28-30.

This Afternoon: A partly sunny afternoon is expected across the entire area with high temperatures between 31 and 36 Degrees. A north wind will continue to gust up to 25 to 30 mph at times and this will put a real chill into the air throughout this afternoon. Tonight: Partly cloudy skies are expected tonight with low temperatures between 20 and 25 Degrees. Sunday: An area of high pressure will provide a sunny day across Western and Central Mass on Sunday, however, there may be a few high clouds around from time to time. High temperatures on Sunday will be between 35 and 40 Degrees. Next Week’s Weather: Quiet weather is expected to continue through at least Wednesday and probably even Thursday of next week as the overall storm track should keep any storms to our south. Generally sunny skies are expected on Monday, Tuesday, Wednesday and Thursday with high temperatures all 4 days between 35 and 40 Degrees. I do still think that we will need to watch the track of any storms between Friday and next Monday (between January 15 and January 18) as it looks pretty likely that we will see an upper level trough of low pressure swing into the Eastern United States. This could lead to a coastal storm impacting our area with accumulating snow. The guidance is currently in a high level of flux right now due to the fact that the overall weather pattern will be undergoing a large scale change towards colder and stormier weather for later this month. When this occurs, you will see huge changes and huge differences in the weather model guidance. This means two things – One is that there is a high amount of uncertainty in the weather forecast for late next week and next weekend. Two is that the weather app on your phone or tablet is going to be useless in showing the weather forecast for next weekend as it will likely change A LOT in the coming days. The reason why is that weather forecast on your app is based off of ONE weather model and has ZERO human input. This means that when that model is wrong, your app will be wrong. So, user beware. With all of that said, I think that there are two time periods we will need to watch for accumulating snow across our area. The first is on Friday as an Arctic cold front may push across the region causing the development of a low pressure system near the Cape. This may lead to some snow across the area on Friday. The second time period to really watch is next Monday as it’s possible that another low pressure system could track across the area bringing snow to the area.
