    (Published Tuesday, Jan. 22, 2019)

    Highs today soared into the low 20s and the wind relaxed as it felt like a big warmup compared to the extremely low temperatures and wind chills of Monday.

    We had a few record-cold-high temperatures for Jan. 21. Boston had a high of 10, the old record of 12 was set in 1985. Worcester had 1 for a high with the old record high of 8 set in 1985. Hartford had a high of 5 with the old record of 8 set in 1985. We turn icy overnight with lows in the teens.

    Wednesday morning we wake up to ice again and cloudy skies. But our temperatures soar into the upper 30s by lunchtime. Highs in the low to mid-40s in the evening thanks to a strong south wind. Rain chances increase for the evening with western New England seeing scattered showers first. There will be a brief chance for freezing rain across higher terrain in Vermont, New Hampshire, Massachusetts and changing to rain late afternoon. Rain holds off in the Boston area until after 4 p.m.

    Occasional rain, heavy at times, continues through Thursday afternoon. One to two inches of rainfall accumulation could lead to urban and river flooding. Make sure storm drains are clear of snowpack and sump pumps are good to go. Colder air returns Thursday evening as the rain tapers off.

    A wintry mix and some snow will be possible in the mountains with a light accumulation. There won't be a flash freeze for southern New England, but it will turn icy Thursday night. Temperatures will in the low 50s by Thursday.

    The wind is something to watch across the south coast, Cape Cod and the Islands as we head into Thursday morning. Gusts may be as high as 40 or 50 mph from the south... if we can get it to mix down. There’s a slim chance for a thunderstorm too. That could help get higher wind gusts to mix down.

    We cool to highs in the mid-30s on Friday. An arctic front brings a chance for spotty snow squalls Friday into Saturday north and west, reinforcing the colder temps.

    Sunday through Wednesday there are several systems brewing. The jet stream and pattern looks to support coastal storm development. Stay tuned for more info from the First Alert Weather Team.
