Spring-like to winter-like this weekend

Posted: Updated:

Clouds are gradually decreasing this evening and may clear out for a time tonight. Temperatures should fall back into the 40s with some fog possible, then clouds increase as we head into Saturday morning.

The forecast for Saturday has been a tricky one and has been based on figuring out where a cold front will stall. Over the last 48 hours, the trend has been for this front to linger slightly to our north-close enough to keep the warm, spring air to our south and out of reach for western Mass.

We should see a little sunshine Saturday morning with temperatures climbing into the 50s and possibly nearing 60 in the lower valley. Since this front is moving from north to south, most in Franklin, northern Berkshire county will turn colder quicker with highs only around 50. Clouds increase throughout the morning and as the cold front pushes through, we will see a significant temperature drop. Light, spotty showers are possible in the afternoon and evening.

As we move into Saturday night, temperatures continue falling-but the cold air is shallow-meaning temperatures higher in the atmosphere are warmer. With this setup, we run the risk to see rain mixing with and changing to sleet and freezing rain.

A Winter Weather Advisory has been issued for all of Franklin and Berkshire counties as well as western Hampden & Hampshire for minor icing Saturday night through Sunday.

Strong high pressure to our northeast will cause cold air to damn against the mountains, keeping most of New England unseasonably cold-maybe record-breaking. High temps Sunday only make it into the lower and middle 30s. The icing threat is mainly for the higher elevations and should be a tenth of an inch or less on roads. Much of the icing may occur on elevated surfaces, like tree branches, power lines, vehicles. The lower valley will likely see scattered rain and sleet much of the day with little to no impact on travel.

Low pressure and a strong cold front approach Monday, bringing temps up a bit into the 40s at least, maybe 50s. Rain is likely throughout the day and may be heavy at times with some thunder possible. It will be a breezy day with winds out of the east-southeast. The front exits Monday night and showers taper off. An upper level low will linger over New England, keeping cool temps around for Tuesday. High pressure returns midweek with fair, but cool weather.
