** A Dense Fog Advisory continues for central and eastern Hampden, Hampshire and Franklin Counties until 3 AM Friday. **
Tonight: Areas of mist and fog. Periods of rain, mild. Lows: 40-48 (temperatures hold steady or slowly rise). Winds: Light.
Friday: AM showers or rain ends then overcast. Rain or showers re-develop late. Highs: 42-48 (steady temperatures).
Friday Night: Rain or showers changes to a period of sleet and/or wet snow – ending late. Coating-1″ in the valley, 1-3″ north and west. Lows: 26-32 (icy spots late).
Greetings! Our next wave of rain will push in right before dawn Friday and last into the morning commute. The raindrops and areas of fog will likely make the commute slow. This batch of rain will taper off by late morning and allow for a mainly dry (except for pockets of mist) but overcast day to follow until late.
Late tomorrow into tomorrow evening rain or showers will move back in as temperatures start to cool. The rain will change over to sleet and wet snow from northwest to southeast (higher elevations first). The mix or wet snow will end well before dawn Saturday. At this point just a light accumulation of wet snow and sleet is possible across western Massachusetts with most spots seeing between a coating and 3″. A few locations in the highest elevations of northern Berkshire and western Franklin County could see locally higher amounts.
The weekend is looking bright but colder. Saturday will be brisk and chilly with skies becoming sunny. Skies will stay clear of clouds into Sunday afternoon before high clouds from our next storm start to arrive.
Low pressure will develop over the Deep South Sunday and move up the Appalachians Sunday night. It eventually tracks to our west overnight but at this point there should be enough cold air in place that when precipitation breaks out towards dawn Monday, temperatures will be cold enough for it to begin as snow. Then snow will gradually change over to sleet and freezing rain Monday morning (making for a possible tricky commute) with showers or rain continuing into much of the day. After that it turns blustery and cold for Tuesday and Wednesday.
Have a great evening!
