For Tonight: A wave of low pressure will move along a frontal boundary that’ll be gradually sinking southward into our area. A lot of moisture will stream northeastward along this front leading to rain to occur tonight with the rain falling at a moderate to heavy rate at times. Rain will begin across all of Western and Central Mass between about 8 and 10 pm this evening. The rain is then expected to continue throughout the rest of the night and it will be moderate to heavy at times. Up to one half of an inch of rainfall can be expected tonight. Temperatures tonight will be between 45 and 50 Degrees. Sunday: The steady rain will likely come to an end by about 9-10 am or so on Sunday morning. The rest of Sunday looks cloudy and mild with perhaps a passing shower or two. Temperatures on Sunday will remain steady between 45 and 50 Degrees. Sunday Night: A cold front will push across the area during Sunday evening. This front will usher in some much colder air. Any leftover rain showers will end early in the evening with clearing skies expected after midnight. Low temperatures Sunday night will be near 20 Degrees. Monday: A cold and windy day is expected on Monday under lots of sunshine. High temperatures Monday will be between 25 and 30 Degrees. North winds will gust up to 30 mph at times with wind chill temperatures in the teens all day long. Monday Night & Tuesday: An area of high pressure will build into the area on Monday night with clear skies and cold temperatures expected. Low temperatures Monday night will be between 10 and 15 Degrees. A sunny day is expected on Tuesday with high temperatures near 35 Degrees. Wednesday: A fast moving wave of low pressure will cross southern New England during the day on Wednesday. This means that skies on Wednesday will be cloudy and there will be a period of showers from late morning into the afternoon hours. High temperatures on Wednesday will be near 45 Degrees. Thursday: It looks like we will be in-between weather systems on Thursday. So, while it looks like it’ll be dry, it also looks like it’ll be cloudy throughout the day on Thursday. High temperatures Thursday will be near 40 Degrees. Friday: I am keeping a very close eye on a storm system that has the very real potential to bring weather impacts during the day on Friday. An area of low pressure is expected to take shape over the lower Mississippi Valley and the Ohio Valley on Thursday. This storm system is expected to head northeastward reaching Southern New England on Friday. As I mentioned yesterday, the track of this storm will be crucial in determining whether this will be a snowstorm, another mixed bag of precipitation or a rain storm. Unfortunately, it’s still way too early to determine what type of a track this storm may take. One thing to note is that the weather forecast guidance, as a whole, have trended towards a colder solution and seems to be forecasting more of a winter weather event rather than a rain event. This seems to fit with the upcoming weather pattern which will be one of a mean upper level trough of low pressure setting up over the eastern United States starting late next week and continuing through at least January 15-20. This would mean that real winter is coming and a period of below average temperatures are likely, especially during the weeks of January 10th and January 17th. The storm track will also need to be watched for snow and ice threats during this time period. Bottom line is that the weather looks quite inclement for Friday with the potential for a potpourri of precipitation from snow to sleet and even rain. This will be followed by a stretch of cold weather beginning next week (week of January 10).
