For The Rest Of Today: Low clouds and fog in the Connecticut River Valley is expected to persist into at least late this morning and possibly early this afternoon as a persistent inversion hangs tough. Elsewhere across Western and Central Mass, skies are expected to be sunny to partly sunny the rest of this morning with gradually increasing clouds expected this afternoon. High temperatures this afternoon will be between 50 and 55 Degrees. A Soaking Rainfall Is Expected From Late Tonight Through Saturday & Saturday Night: An area of low pressure near the eastern Great Lakes is expected to redevelop near the south coast of New England by late tonight and Saturday morning. This new low pressure system is then forecast to move into the Gulf of Maine on Saturday afternoon while a third brand new low pressure system forms off of the Mid-Atlantic coast. This third low pressure system is expected to move right across New England on Saturday night. The combination of all three weather systems will bring a soaking rainfall to all of Western and Central Mass beginning late tonight and continuing through all of Saturday and all of Saturday night. Rain will overspread the entire area between about midnight and 3 am tonight and then continue right through the entire day on Saturday. The rain is expected to be heavy at times during the day on Saturday. It now appears that the rain will continue through much of, if not all of Saturday night and it may be heavy at times. The rain will finally come to an end very late Saturday night or early Sunday morning. Total rainfall amounts from late tonight through Saturday and Saturday night will average between 1 and 2 inches. Localized urban and poor drainage flooding will be a concern, especially where many storm drains are now clogged by fallen leaves. Low temperatures tonight will be near 45 Degrees. High temperatures Saturday will be between 55 and 60 Degrees. Low temperatures Saturday night will be between 45 and 50 Degrees. Trick-Or-Treat Weather Forecast Late Saturday Afternoon & Saturday Evening: I know that some towns are doing trick-or-treating on Saturday instead of Sunday and unfortunately the weather does not look good. The weather for late Saturday afternoon and Saturday evening looks very wet with rain, which will be falling at a moderate to heavy rate at times. Temperatures during the late afternoon will be near 55 Degrees and temperatures during Saturday evening will also be near 55 Degrees. Sunday (Halloween) Forecast: That entire stormy weather system will pull away into Atlantic Canada during Sunday, however, some leftover moisture will lead to a mixture of sunshine and clouds throughout the day Sunday. In addition, a couple of pop up showers are possible from time to time on Sunday. High temperatures Sunday will be between 60 and 65 Degrees. For Sunday night, skies are expected to be partly cloudy with low temperatures near 45 Degrees. Trick-Or-Treat Weather Forecast Late Sunday Afternoon & Sunday Evening: Partly cloudy skies. Temperatures during the late afternoon will be between 58 and 62 Degrees and temperatures during Sunday evening will be near 55 Degrees. Next Week’s Weather Forecast: An area of high pressure will control the weather for early next week. This means that Monday will be sunny with high temperatures between 55 and 60 Degrees, Monday night looks clear to partly cloudy with low temperatures between 35 and 40 Degrees and Tuesday is expected to be partly sunny with high temperatures near 55 Degrees. By Tuesday night into Wednesday, a weak cold front is expected to push across the area. There may be just enough moisture with this front to produce a couple of rain showers on Tuesday night and Wednesday morning. It should be noted that a couple of snow showers could occur in the Hilltowns of Western Mass, the Berkshires and the Worcester Hills. Skies then clear out during Wednesday afternoon. Low temperatures Tuesday night will be near 35 Degrees. High temperatures Wednesday will be near 50 Degrees. By later next week, an upper level trough of low pressure will set up over the eastern United States. This will lead to cooler than average temperatures for the second half of next week through next weekend. Low temperatures for Wednesday night and Thursday night will probably fall into the upper 20s to low 30s with high temperatures on Thursday and Friday of between 45 and 50 Degrees Little pieces of energy will rotate around this trough of low pressure to produce the chance for the first widespread scattered snow showers of the season Wednesday night and early Thursday morning. By late next week, the weather forecast becomes much more uncertain as some of the weather forecast guidance points to a low pressure tracking near the south coast of New England on Thursday night and towards the Gulf of Maine on Friday. Other weather forecast guidance, however, show this storm system to remain well south of the area. This difference means a lot in terms of weather conditions. A storm track near the south coast of New England would mean everything from rain in the Connecticut River Valley and the Blackstone Valley to accumulating snow in the Berkshires and the Worcester Hills on Thursday night and Friday. On the other hand, a storm track that stays well south of our area would mean dry weather for late next week. My thinking at this early point in the forecast is for perhaps a storm track that tracks just southeast of Nantucket on Thursday night and then towards Nova Scotia on Friday. A track like this could mean some accumulating snow along and east of I-84 and also near and south of Route 9 in Central Mass. Elsewhere, this type of storm track would be far enough away for much of Western Mass to remain dry with dry weather also possible across northern parts of Worcester County. I’m just spit balling at this point and a lot can change in the forecast between now and late next week. At this point, it’s nothing to be concerned about, but it is something to certainly keep an eye on.
