The Show Called Spring Is Over

Posted by Chris Lambert

We reached the mid 50s this afternoon, although with such a strong wind, it definitely didn't feel quite as warm.  That southwest wind is now a northwest wind and that closes the Spring show we've had for the weekend.  Colder air pours into southern New England tonight, and by tomorrow morning, temps are back into the teens and lower 20s.

The cold weather sets the stage for snow.  An upper-level low drifts in from the west Monday afternoon providing enough instability to bring in some flurries and light snow by day's end. 

Things get interesting overnight... to say the least.   The upper-level energy captures moisture from an ocean storm far out, draws some of that moisture in, and with instability in the atmosphere set-up across New England thanks to cold air rushing in aloft, snow becomes steady predawn Tuesday, through Tuesday mornings commute.   In this type of situation (Norlun Trough or inverted trough.. technical name) snow amounts from town to town can vary quite a bit.  I'm thinking 1-3" west of I-93 and west of Rt. 24. 3-5" are likely closer to the coast, in part from a coastal front that sets up early in the morning to aid in istability and moisture.  Within that 3-5" there is a possibility of localized bands setting up (tends to be north of the Norlun trough axis), where a few towns could well exceed the 5". The best chance for that is Cape Ann to the Seacoast of NH and coastal southern Maine, as well as the Cape.   To pinpoint the towns in line for that now is a tough promise since we need to know exactly where that trough sets up.  The snow will be light and fluffy, and temps fall into the teens Tuesday afternoon.

Tuesday night-Thursday look cold, in fact, mornings start near 0 Wednesday and Thursday, and highs Wednesday hit 15 if you're lucky.  Then more snow Friday!  Welcome back winter, right?

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.

Pretty Good Weekend Overall

Sure, it's a cool start with many of the suburbs down into the upper 30s and lower 40s, but we'll warm up quickly through the day as that sun helps us out.
