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?

More Warmth

You have another warm & humid day with many towns repeating yesterday's weather. That means we start with clouds & fog for a bit before hazy sun gets going. That hazy sunshine will boost temps up into the low 80s by early to mid afternoon across much of the region. At the same time a cool front will begin dropping out of Maine (backdoor front) which will quickly send temps from the 70s/80s down into the 50s/60s by late afternoon & evening. Also, when this front rams into the warmth & humidity it will spark a few showers & thunderstorms during the afternoon.

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.

Feet First

Right into summer. Warm & humid weather expected for much of the week. Good?.....Well, keep in mind that warmth & humidity are the 2 key ingredients for thunderstorms. The last being something to *lift* that warm/humid air. Usually a front is a good device to do such that. Today, we will have a cool front approach New England very late in the day & evening. That may lead to an isolated storm or two after 4pm but most towns just have a fair amount of clouds, warmth & humidity. Temps will climb to near 80 by afternoon.

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.
