Rain With Much Colder Temperatures Expected Sunday Afternoon Through Monday

For The Rest Of This Afternoon: Probably the last really warm temperatures until next Spring are expected throughout the rest of this afternoon across the entire area. Skies through mid-afternoon will be sunny to partly sunny with more clouds expected by late afternoon as a cold front pushes through the area. It’s possible that this front could produce an isolated shower or two across the region between about 4 pm and 7 pm. It should be noted though that any isolated showers will be very short-lived and fast moving and most areas will stay dry. Temperatures during the rest of this afternoon will be between 75 and 80 Degrees. Winds will be West at 10 to 20 mph with gusts to 30 mph. Tonight: An area of high pressure is expected to temporarily control the weather tonight. This means that skies this evening will be clear to partly cloudy, but clouds will be on the increase after midnight tonight as a low pressure system begins to approach our area from the west. Low temperatures will be near 45 Degrees. Winds will be North to Northwest at 10 to 20 mph. Sunday Through Monday: A couple of low pressure systems will push east-northeast through our area during Sunday and Monday. These storm systems will bring a couple of rounds of rain to the region. In addition, temperatures are expected to be some 30 Degrees colder on Sunday as compared to today and this is going to be a shock to the system, for sure. Sunday will be cloudy and rain is expected to overspread the entire area during the early and mid-afternoon hours. Temperatures on Sunday are expected to be in the 44 to 49 Degree range. Winds will be Northeast at 5 to 10 mph. Periods of rain is expected to continue throughout Sunday night with a much more steadier rain overspread the area towards dawn on Monday morning. Temperatures on Sunday night will be around 45 Degrees. Winds will be Northeast at 5 to 10 mph. Rain is expected to continue throughout Monday morning before it tapers off to scattered showers during Monday afternoon. High temperatures on Monday will be between 50 and 55 Degrees. Winds will be North at 5 to 10 mph. Total rainfall amounts from Sunday afternoon through Monday are expected to average between one half of an inch (0.50”) and one inch (1.00”) across the entire area. Halloween: Tuesday looks to be a partly sunny day with high temperatures between 45 and 50 Degrees. Snow Is A Possibility For Late Tuesday Night Through Wednesday: The weather forecast becomes a lot more uncertain as we get into Tuesday night and Wednesday. The reason why is because it is expected that a coastal storm system that moves northeastward somewhere near the south coast of New England and the Cape. The track of this storm system is going to be extremely important in determining what sort of weather we see on Tuesday night and Wednesday. On one hand, some of the weather forecast guidance such as the GFS model forecasts a storm that stays well offshore leading to a cloudy, but quite chilly Tuesday night and Wednesday. On the other hand, other weather forecast guidance such as the European model is showing a more dynamic storm system that tracks just east of Nantucket during Wednesday. This is a storm track that is close enough to bring the first accumulating snow of the season across the Worcester Hills and the Berkshires late Tuesday night into Wednesday (although it doesn’t look like more than an inch or two of snow) and more of a rain-snow mix across the rest of Western and Central Mass. I think that the weather forecast guidance such as the GFS model is too progressive and way too far southeast with the track of the storm. Instead, I think we may see a storm track that’s close enough to bring the area inclement weather later Tuesday night and Wednesday. In terms of precipitation type, I think that locations in the Worcester Hills and the Berkshires that are 500 feet in elevation or higher have the greatest chance of seeing wet snow occur beginning late Tuesday night and continuing through Wednesday morning. This snow will probably change to either a rain-snow mix or all rain during Wednesday afternoon before ending during Wednesday evening. Snow amounts over areas that are 500 feet or higher in elevation may be an inch or two of slushy accumulation. At the lower elevations of Western and Central Mass, especially in the Pioneer Valley and the Blackstone Valley, the precipitation looks to be a rain-snow mix that doesn’t accumulate late Tuesday night and Wednesday morning. This then changes to all rain by Wednesday afternoon. Rain then ends by Wednesday evening. While this does look like a minor snow event, it is something that’ll be watched, just in the off chance that it becomes something bigger. Low temperatures Tuesday night will be between 31 and 36 Degrees. High temperatures Wednesday will be near 40 Degrees. Black Ice Possible Wednesday Night Along With A Likely Hard Freeze: The first hard freeze of the season is likely on Wednesday night as low temperatures of 25 to 30 Degrees are expected. Additionally, residual moisture left over from the precipitation on late Tuesday night and Wednesday may be still present on roads, highways, parking lots and driveways during Wednesday night. This could lead to the possibility for areas of black ice on roads, highways, parking lots and driveways during Wednesday night. Be aware of this if you have plans on Wednesday night.
