More Winter Weather Is Expected From Thursday Afternoon Through Thursday Night & Friday: Even though Wednesday looks dry with no weather problems, we are expected to see another round of accumulating snow on Thursday afternoon, Thursday night and Friday. Wednesday looks sunny, but cold with high temperatures between 25 and 30 Degrees. An area of low pressure is expected to move from the Southeastern United States on Wednesday night and Thursday to near Nantucket on Friday. It now looks like the slightly more offshore track of this storm will allow colder air to remain entrenched across the region leading to either an all snow scenario or an almost all snow scenario across Western and Central Mass. Snow will overspread Western and Central Mass during the early afternoon hours of Thursday. The snow is then expected to continue through the rest of Thursday afternoon, all of Thursday night and much of the day on Friday. 2 periods of moderate to perhaps even heavy snow is possible with this storm – the first is during the mid and late afternoon hours of Thursday with the second possibly occurring from late Thursday night through Friday morning. So, to sum up this storm for you – Snow begins during the early afternoon hours of Thursday and possibly becomes moderate to heavy at times during the mid and late afternoon hours of Thursday. A period of steady light snow is then expected during Thursday evening with a period of moderate to heavy snow possible from about midnight Thursday night into Friday morning. Light snow is then expected again Friday afternoon with the snow ending late Friday afternoon or early evening Friday. My snowfall forecast map is attached to this post.


This Weekend Looks good with no weather problems expected. Saturday looks partly sunny and windy with high temperatures near 30 Degrees. Sunday also looks partly sunny with high temperatures between 30 and 35 Degrees. The Next Chance For A Storm To Watch Will Be on Monday and Monday night as a fast moving low pressure system crosses Southern New England. This storm could bring another round of snow that probably will be mixed with rain with high temperatures in the upper 30s.

Snow, Ice & Rain Expected Tonight Through Tuesday Morning: An area of low pressure is expected to track from the Southeastern United States this afternoon and tonight and then across some part of Southern New England during Tuesday morning. This storm system is expected to bring a wintry mess of precipitation to the entire area beginning around midnight tonight and continuing through Tuesday morning. It looks like initially freezing rain will move in around midnight tonight across the entire area as warmer air aloft bumps into cold air near the surface. The big question and kind of unknown with this storm is whether or not the freezing rain will change to rain or not, and if so, when. This is extremely important because if we do change to rain like some of the weather forecast guidance suggests, we will prevent ourselves from seeing a significant ice storm (Great News!!). My concern is that the surface winds tonight and Tuesday morning are expected to be from a north to northeast direction and this could lead to a situation where the sub-freezing air near the surface has a tough time being scoured out leading to a prolonged freezing rain event. Based on everything that I’ve looked at today, here are my thoughts: For The Lower Pioneer Valley & Southern Worcester County, Including Springfield & Worcester: Freezing rain begins around midnight tonight and continues for a few hours late tonight. A gradual change from freezing rain to rain is forecast near sunrise Tuesday morning. During Tuesday morning, it may just be barely warm enough for the precipitation to fall as rain across the lower Pioneer Valley and across southern Worcester County, but I think it could be close (33 to 35 Degrees). The rain is expected to come to an end around midday on Tuesday. For The Upper Pioneer Valley, The Berkshires & Northern Worcester County, Including Fitchburg, Gardner, Deerfield & Blandford: Freezing rain is expected to begin around midnight tonight and the freezing rain is expected to continue through the rest of the night tonight and into Tuesday morning. There is the potential that the precipitation across the Berkshires, the upper Pioneer Valley and northern Worcester County remains as freezing rain with temperatures staying in the 29 to 31 Degree range. This could lead to around one-half of an inch of ice accumulation. This significant amount of ice is likely to lead to extremely hazardous travel conditions, power outages and tree damage. The freezing rain is expected to come to an end around midday Tuesday. My latest forecast ice accumulation map is attached to this post.

Another Significant Winter Weather Event Looks Likely From Thursday Afternoon Through All Day Friday: If one storm to try and forecast wasn’t enough, another storm system looks likely to impact Western and Central Mass beginning on Thursday afternoon and continuing through Thursday night and Friday. It is possible that this storm could be even more impactful than the one expected for tonight and Tuesday morning. An area of low pressure is forecast to head from the Southeastern United States on Thursday to near Nantucket by Friday afternoon. This storm looks colder in nature than the one that is expected for tonight and Tuesday morning, this means that this second storm looks to bring mainly all snow to the area. It appears that snow will overspread Western and Central Mass just before midday Thursday and then continue through all of Thursday afternoon, Thursday night and a large part of Friday. It is possible that some freezing rain and sleet could mix in with the snow near and south of the Mass Pike late Thursday night and Friday morning. The snow with this second storm system looks to come to an end early Friday evening. My first thoughts for snow amounts from Thursday afternoon through Friday look to range from 4 to 6 inches or so across the lower Pioneer Valley and southern Worcester County to 6 to 8 inches or so of snowfall across the upper Pioneer Valley and across northern Worcester County.

Tonight: Mostly cloudy, but dry conditions are expected tonight across Western and Central Mass. Low temperatures tonight will be near 25 Degrees. Monday: Monday is expected to be a very changeable weather day across the area. A southwesterly moist wind flow ahead of an approaching storm system from the southern United States will lead to a period of light snow that may mix with some sleet and freezing drizzle. The timing for this period of wintry weather looks to be from about 11 am to about 3-4 pm. A second period of light snow and freezing drizzle is possible from 5 to 7 pm Monday evening. All-in-all, it looks like snow and ice amounts will be very light with a dusting of snow possible and an extremely light glaze of ice also possible. With that said, even a very light glaze of ice could lead to some slick conditions at times on Monday, so use caution if you are out and about. High temperatures Monday will be around 30 Degrees. Significant Winter Weather Expected Monday Night Through Tuesday Morning: An area of low pressure is expected to track from the Southeastern United States on Monday night to across the Cape during Tuesday morning. I am becoming increasingly more concerned that we are going to see significant ice accumulations across a large part of Western and Central Mass late Monday night through Tuesday morning. Let’s break down the risks: Snow: Periods of light snow is likely to be occurring during early Monday evening, This light snow should end for a while with heavier precipitation moving in by about midnight Monday night. I think initially the precipitation will be in the form of snow and sleet north of the Mass Pike, but freezing rain mixed with sleet along and south of the Mass Pike. The precipitation looks to change to all freezing rain across much of Western and Central Mass by sunrise Tuesday morning. The exception looks to be near and north of Route 2 where sleet is expected by Tuesday morning. Right now, it looks like the upper Pioneer Valley, the Berkshires and the northern Worcester Hills will see 1 to 2 inches or so of snow accumulation before it changes to sleet. Elsewhere across Western and Central Mass, it looks like it could be all ice with this storm! Significant Ice Accumulations Possible: The big issue with this storm is going to be the ice accumulation potential as milder air moves northward into the area while sub-freezing air remains near the ground. I think that we will see snow and sleet north of the Mass Pike initially starting around midnight Monday night with freezing rain possibly mixed with sleet along and south of the Mass Pike. This should transition to all freezing rain by sunrise Tuesday morning across most of Western and Central Mass. The exception may be near and north of Route 2 where the precipitation may be more sleet than freezing rain. During Tuesday morning, I think that we’ll probably see sleet near and north of Route 2 with freezing rain expected across the remainder of Western and Central Mass. All wintry precipitation with this storm is expected to come to an end by early Tuesday afternoon. My forecast ice accumulation map is attached to this post.



I definitely think that the area from the lower Pioneer Valley eastward to southern Worcester County and southward into northern and central Connecticut have the highest chance of seeing significant amounts of freezing rain of up to one half of an inch. This area includes Springfield, Worcester and Hartford. This significant amount of ice is likely to lead to extremely hazardous travel conditions, power outages and tree damage. This is a storm that I am watching extremely closely and I will continue to have at least once a day updates for you. Another Significant Winter Weather Event Still Possible From Thursday Afternoon Through Friday: Yet another storm system is expected to reach Southern New England by Friday morning. To be honest, I really didn’t take a thorough and in-depth look at this second storm as I have my hands full with the first one. From what I did look at, there are no changes to my thinking. At this point, I think that a mix of snow and sleet is possible along and north of the Mass Pike and a mix of freezing rain and sleet is possible south of the Mass Pike from Thursday afternoon through Thursday night and most of the day on Friday. This storm could bring six inches or greater of snow and sleet along and north of the Mass Pike and the possibility of significant ice accumulations south of the Mass Pike.
