Seasons In Conflict

Posted by Pete Bouchard

Winter and spring are slugging it out in the next 24 hours, and we have a ringside seat.

Cold air is pushing south from Quebec and Ontario. While that isn't anything unusual, it comes at an inopportune time. Clouds and precipitation are moving in at the same time. Typically, that would mean the temperatures would level off or slightly rise overnight. Not this time...by morning many of us will be in the low and mid 30s!

This isn't a time to panic, however. We're talking sleet here.

The precipitation that comes from the cloud first starts as snow. As it falls, it encounters some warm air that melts it into raindrops. Those drops keep falling, and then they encounter a layer of cold air that refreezes them. Instead of snowflakes we get ice pellets or sleet. Sleet is better than freezing rain. Sleet bounces, freezing rain glazes (on EVERYTHING...think ice storm).

Got it? Good.

After the "warm" air pushes in by late AM, we'll go over to all rain, which may add up to an inch or more by late Friday night. Winds will whip at the coast, but be deflected by the cold Metrowest  and throughout the Merrimack Valley and Southern NH. All told though, it will be a nasty day.

In contrast, the weekend is looking pretty good. A get-out-and-prep-the-lawns-and-gardens kinda day. Plenty of sun and on the lower end of 60 (fancy talk for upper 50s).

Next week's warmup is a little stunted thanks to the arrival of a cool front. Either way, we're still WAY above normal, and the 70s will come home to roost once again.

50/50 Weekend

Posted by Chris Lambert

We're off to an iffy start to the weekend as nuisance rain and wet snow moves across the area.  While it's not a well organized area of low pressure, it develops right near us midday, and that'll be enough for a tricky forecast.  Light to moderate  rain/snow is on and off early this morning with a heavier burst of precipitation possible late morning, through mid afternoon in eastern MA (11:00AM-3:00PM).

Final Days

Posted by Pete Bouchard

That's the way to get it done! Fine finish to the workweek as sun dominated and winds behaved.

I submit that is the one - and perhaps only - reason these days have felt springlike in this extended thaw. If the winds were gusty on a day like today, the sun (albeit a little stronger these days) is really no help.

Great Mid-Winter Weather

Posted by Jeremy Reiner

Nice mid-winter weather? Here's how I envision it:

*Sunshine

*Mild temps (40 or higher)

*Little to no wind

That last bullet point (IMO) is probably the biggest when outside this time of year. After our morning fog lifts out of here all three of those criteria will be met this afternoon AND.....it's Friday. #Winning.

Colder Temperatures Cometh

Posted by Pete Bouchard

As far as blah days go, this was the blahest.

Fog blanketed the area as winds remained light and variable. We're still looking at some fog, but the thickest part of it should only be during the first half of the night. After that, gentle winds should "mix out" some of the heavily fogged in areas.
