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. 

Summ-ah!

With the snap of the fingers we were thrown into summer this afternoon. Heat, humidity, A/C and shorts - with a hazy sun to boot. But with the sea breeze knocking back the temperatures (and bringing in a round of downpours this evening), there are changes afoot.

Warming Up and Unsettled

Well, it certainly was a great weekend weather-wise until this afternoon when the temps dropped and light showers moved in from west to east.  Despite the cool down, the theme for this upcoming week is warmer with higher humidity.  It'll also be unsettled at times. 

Pulling The Fade

Our fun in the sun ends this afternoon as morning sunshine fades behind thickening clouds.  As those clouds increase, a few showers break out this afternoon from west to east, with the highest chance for rain late afternoon and this evening.  Most of the showers are light, especially the early afternoon ones, but a heavier shower or two is possible near day's end and early this evening.  Highs reach the mid to upper 60s around noon, then fall back to near 60 mid to late afternoon thanks to scattered showers.  These showers are brought to us by a warm front.

Back and Forth

Quite a few clouds in the sky at times this afternoon, but the atmosphere lacked ample moisture to produce showers, so we made out just fine with temps near 70.  Even the coast made it well into the 60s before the onshore wind knocked temps back.
