For The Rest Of Today: A large high pressure system will bring the entire area plenty of sunshine throughout the rest of today. High temperatures this afternoon will be between 30 and 35 Degrees.
Tonight: That high pressure system will provide clear skies and light winds this evening. This will cause temperatures to quickly fall into the upper teens. Temperatures will then level off in the upper teens or even rise a little after midnight as clouds begin to increase across the region.
Friday: High pressure will move away from our area on Friday and our winds will shift into a southwesterly direction. In addition, there will be an increase in moisture in the atmosphere during Friday that will lead to some areas of light freezing rain and light freezing drizzle across Western and Central Mass during the mid and late morning hours of Friday. This threat for light freezing rain and light freezing drizzle will persist into early Friday afternoon before changing to light rain across Central Mass.
Across the Pioneer Valley of Western Mass, it is likely that the light freezing rain and light freezing drizzle will persist through much of Friday afternoon as a light northerly wind causes cold air to dam up along the I-91 corridor. This means that it may take quite a bit of time for temperatures to rise above freezing across this region. Any ice accumulations on Friday will be light, but it only takes a very small amount of ice to create hazardous travel. This freezing drizzle/freezing rain threat for the Pioneer Valley is something that will need to be watched very closely.
High temperatures on Friday will have a large range from temperatures remaining in the lower 30s all day long along the I-91 corridor in Western Mass to temperatures in the low to mid 40s across the Worcester Hills.
Friday Night Through Saturday: An area of low pressure is expected to develop along the Mid-Atlantic coast on Friday night. Periods of rain are expected across Western and Central Mass during Friday evening with a steady rain overspreading the region just after midnight Friday night. Areas of heavy rain are expected to overspread the region very late Friday night. Temperatures will gradually rise through the 40s throughout Friday night.
On Saturday, rain, heavy at times, is expected throughout the morning with periods of light rain expected during Saturday afternoon. Rainfall amounts from Friday night through Saturday will range from three quarters of an inch (0.75”) to one and one quarter inches (1.25”).
This bout of heavy rainfall along with snow melt will lead to urban and poor drainage flooding across all of Western and Central Mass. In addition, rises in the area rivers and streams are likely and these will need to be watched closely.
High temperatures Saturday will be between 45 and 50 Degrees.
Saturday Night Through Sunday: That low pressure system will move towards Atlantic Canada later Saturday night and Sunday.
Rain will come to an end during Saturday evening with skies remaining cloudy throughout the rest of Saturday night. Low temperatures Saturday night will be near 40 Degrees.
Sunday is expected to be a cloudy and windy day across Western and Central Mass with high temperatures near 45 Degrees. West winds will gust up to 30 to 40 mph at times throughout the day on Sunday.
Possible Snow & Ice From Late Monday Night Through Tuesday: There continues to be rather strong signals in the data that suggest an area of low pressure will travel along the New England coast on Tuesday.
There is likely to be more than enough cold air around for the precipitation to start as snow well after midnight Monday night.
During Tuesday, I think that there is enough evidence in the weather data that suggests that the snow will continue through at least all of Tuesday morning. During Tuesday afternoon, however, there is the potential for the snow to change to freezing rain as milder air tries to work into the area. This change to freezing rain is highly uncertain and it’s quite possible that we may remain as mostly all snow, especially in the Worcester Hills and the Hilltowns of Western Mass.
Snow or freezing rain will come to an end Tuesday evening.
At this time, it is way too early to start talking exact snow amounts for the early week storm. I will say, however, that it is quite possible that there will be enough snow to plow across all of Western and Central Mass beginning late Monday night and continuing through all day Tuesday.
I am watching this storm closely and will keep you all updated.
Will There Be A White Christmas This Year Across Western & Central Mass? We are just 13 days away from Christmas Day & I’m already starting to take a look at the weather forecast for Christmas Week, as well as the prospects for a White Christmas.
Given the current & forecast weather pattern across the Eastern United States, I think that there is a much higher than average chance for a White Christmas this year across all of Western and Central Mass. The weather pattern for next week through Christmas Week looks cold, so any snow that accumulates early next week will likely remain on the ground right through Christmas.
The weather for Christmas Week looks potentially quite wintry as there are signs in the long range weather data that suggests we could see another accumulating snow event around December 23rd. An early look at the weather for Christmas Eve and Christmas Day reveals that weather conditions may be dry and cold across all of New England.
Beyond that, another storm system could bring snow or ice to Western and Central Mass around December 27 or 28.
Obviously, I am keeping very close tabs on the weather for Christmas week and I will keep you all updated.
