Berkshire County Forecast-Friday, Jan. 31

Note: Clicking on underlined red text provides links to various weather maps.

SummaryIt looks like the weak storm passing by to our northwest this weekend will not make much of an impact in Berkshire County. The warm front should pass through dry on Saturday. There should be nothing more than some drizzle after midnight on Saturday due to a low overcast and some fog. However, those in the elevated terrain may see a few pockets of freezing drizzle. As the trailing cold front moves through on Sunday there is just the chance of a few scattered, light rain showers. It will also be quite mild this weekend compared to recent weeks.

It still appears that once the cold front stalls and becomes stationary to our south, a surface low  pressure system tracking along the front will pass by to our south on Monday but it may be a close call so I will keep an eye on that over the weekend. A more potent storm will likely impact us Tuesday night and Wednesday. Right now it looks like accumulating snow late Tuesday night, with as much as 6-8″ by morning, with a changeover to sleet and freezing rain during Wednesday morning as the storm moves out. However, my experience with these types of storms is that the changeover to sleet and freezing rain frequently occurs sooner than the models indicate this far out so it is likely that we will get less snowfall than that. Also, the jet stream pattern will not be particularly amplified so it looks like the storm will move through quickly and that this event may last 12 hours or less. However, it looks like Wednesday morning may be a tough commute.
