For The Rest Of Today: An area of high pressure will push off of the New England coast today. This will cause the overall wind flow to become southwesterly as the day progresses. This will lead to increasing amounts of moisture and milder air to push into southern New England.
So, for the rest of today, skies will be cloudy and there will be areas of fog and drizzle. A few showers are possible during this afternoon across Western and Central Mass. High temperatures this afternoon will be near 65 Degrees.
Tonight: A warm front is expected to push northward across the region tonight. Scattered showers are expected this evening with widespread showers overspreading the area after midnight tonight. These showers are expected to taper off and end in many places around sunrise Thursday morning.
Low temperatures tonight will be between 55 and 60 Degrees with increasingly more humid conditions.
Halloween Day: An increasing southerly wind flow over southern New England will pull mild and humid air into Western and Central Mass during Thursday.
Scattered showers are expected on Halloween morning. During the afternoon, widespread showers with locally heavy rainfall is expected. In addition, south winds are expected to gust up to 25 to 35 mph at times during the afternoon.
High temperatures on Halloween Day will be between 66 and 69 Degrees with humid conditions.
Halloween Night & Friday: The overall weather forecast remains about the same as what I wrote yesterday.
An area of low pressure is expected to track up the St. Lawrence River Valley in southern Quebec province on Thursday night before moving right across northern Maine and northern New Brunswick on Friday. This storm system will pull a strong cold front right across Western and Central Mass late Thursday night and Friday morning.
This storm system will bring a combination of heavy rain, gusty winds and the possibility of a thunderstorm or two to Western and Central Mass mainly on Halloween night and Friday morning.
Gusty Winds: The overall wind field with this storm system will increase starting late Thursday afternoon and then continue through Thursday night and Friday.
It appears that there may be two periods of gusty winds that will impact Western and Central Mass.
The first will be during the overnight hours of Halloween night ahead of the eastward moving cold front. Overall, it looks like south winds will gust up to 25 to 35 mph at times during Halloween night. What we will need to watch out for is the possibility for localized wind gusts of up to 50 mph that could occur with a line of heavy showers and possible thunderstorms that will move through between 2 am and 5 am Friday morning.
The second round of gusty winds will occur beginning between 4 and 5 am Friday morning. These gusty winds will continue through much of the day on Friday on the backside of the cold front. Winds are expected to shift into a westerly direction and gust up to 35 to 45 mph around 4 to 5 am Friday morning. These 35 to 45 mph westerly wind gusts are then expected to continue throughout the day on Friday.
Heavy Rain With A Chance For A Thunderstorm Or Two: Widespread showers with locally heavy rainfall is expected throughout Halloween afternoon. One change to the forecast is the possibility that the rain may stop for a while between 7 pm and midnight or so Halloween night.
A period of heavy rain with the possibility for a thunderstorm or two will overspread Western and Central Mass between midnight and 2 am and then continue until about 7 to 9 am Friday morning. Rainfall amounts with this storm system will range from around one half of an inch (0.50”) across Central Mass to as much as around one inch (1.00”) of rainfall across Western Mass.
Rain ends by 7 to 9 am Friday morning with skies expected to become partly sunny by midday Friday. Partly sunny skies are then expected throughout Friday afternoon.
Temperatures: High temperatures on Halloween Day will be between 65 and 70 Degrees. In addition, it will be humid on Halloween Day. Temperatures on Halloween night will be between 55 and 60 Degrees with humid conditions. Temperatures on Friday will start out near 60 Degrees, but will fall through the 50s during Friday afternoon with much less humid conditions.
This Weekend: It currently looks like dry weather is expected for this weekend with sunny to partly sunny skies for both Saturday and Sunday. High temperatures Saturday will be between 50 and 55 Degrees. High temperatures next Sunday will be between 50 and 55 Degrees.
Monday & Tuesday: Plenty of sunshine is expected on Monday with high temperatures between 50 and 55 Degrees.
A southerly wind flow is expected to set up on Tuesday well ahead of another frontal system. This will lead to a mixture of sunshine and clouds on Tuesday along with some scattered shower activity during the afternoon. High temperatures Tuesday will be between 55 and 60 Degrees.
Weather Forecast For Late Next Week & Next Weekend Looks “Interesting”: I am watching the weather for late next week through next weekend with quite a bit of interest. The reason why is because an area of low pressure may cross the region next Thursday night and next Friday. There is expected to be quite a bit of cold air around for late next week that this low pressure may try to work with.
This potentially means that at the minimum some scattered snow showers could occur across parts of Western and Central Mass late next Thursday night and next Friday morning. At this time, any accumulating snow should stay just north of our area across parts of Vermont, New Hampshire and Maine, but it is something that will need to be watched closely.
Additionally, next Sunday and Veterans’ Day also will need to be watched closely for the potential of another low pressure system that may cross the region bringing with it some snow shower activity & the slight possibility for a little bit of accumulating snow.
