Melt/Refreeze Cycle

Posted by Chris Lambert

What a mid-March day!  Lots of sun (except for the Cape) and lots of snow melting going on.  What a difference in temperatures too.  We only managed the upper 30s at the coast, but hit the low to mid 50s north and west of 495.  Fitchburg came in at 55 degrees.  An onshore component to the wind kept us much cooler inside 128. 

Good set-up tonight for temps to fall fast once the sun sets and that means our snowmelt refreezes into black ice on the sidewalks, driveways and side streets.  Temps cool the fastest away from the coast, with upper teens in the colder Worcester County and southern NH valleys to the low to mid 20s in many of the Boston burbs, to about 32 in the city.   With some marine air lingering around, I can't rule out patchy fog from forming overnight.

Tomorrow looks good again, maybe not a cloudless sky, but we'll take at least partly sunny skies again.  Temps are fairly similar with highs near 40 at the coast, and closer to 50 well inland.

Temps warm-up even more Monday and Tuesday, and that means 50s for many!  Monday still features mid to upper 40s at the immediate coast, but warm enough to melt more snow.  Tuesday brings us rain... and it WILL be rain this time.  Depending on how the evolution of a wave of low pressure forms along this front, we could wring out at least an inch of rain.  While that wouldn't cause significant river flooding, we may see swollen streams from snowmelt and rain, and I certainly can see us dealing with big puddles/ponding on the roads for the Tuesday evening commute.

Wednesday is a transition day.  We'll near 50 by mid-day, but that active west wind advects in cold air late in the day and by Thursday morning, you'll feel the difference.   A colder pattern is where we stay into the weekend.

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:


*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'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.
