Get em in soon 

Earlier guidance showed more potential for cooler
northern stream energy to bring cooler temps southward; but most
models now show enough ridging aloft to suppress this well to our
north and east. Given this trend, the potential for 80-degree
temperatures exists at least across the interior looking into
Wed and Thurs. Spread in the guidance on temps is still
considerable though: some 20 to 25 degree differences between
the 10th and 90th percentile NBM high temperature values which
helps put the uncertainty in some context. The deterministic NBM
is something of a middle ground on temps and will stick close
to it. It still features above normal temps in the period, but
could be significantly warmer than presently depicted if current
trends hold.

Oh noes! Not an 80° day. What will we do?

High pressure over the Ohio Valley slowly builds east toward New
England, providing warm afternoons and cool nights.

Didn't see this posted.  I wonder why.  Hmmm.

Seems odd that my area in west-central Maine is now white.  It was in the yellow right after April ended and we've had only 0.67" in May, <50% of normal and not the way to bury Stein.  Maybe the April 30 rain wasn't part of the earlier map?

The lack of synoptic precipitation events all winter played a bit role.  Survived on upslope which really only hits the narrow spot along the Spine.  The NE VT area stays dry for the most part.

We had a pretty wet April as a state on the whole.  The past 6 weeks have been wet it's seemed just anecdotally.

Got chillier last night than I thought it would.  Bradley CT, Nashua NH and Bedford MA all pinged 39 - decoupling's a 'cast killer.

But, it's also warmer by hour this morning's recovery than I imagined, too - 69 already here as of 9:15 am with a few 70 even ... home stations dappled about. 

Fithchburg MA is 66 at 9: am, and Boston knocks the door of 70 too if not already there.

76 incoming ... The sounding exposes this as a weird scenario, actually.  I mean 500 mb thicknesses are still chilly, mid 540s... You don't typically see temperatures bathing the surface in mid or even upper 70s along with/under that metrical condition - more like a triple nickels dm thickness for that range.   It's like the warmth is stacked in the bottom of the atmosphere ... It's making the conditions unstable.   LI's reflect that being down to 0 to +2 range .... Low DPs are probably making parcels invisible - lol... Like invisible CB.. kidding. But, we might still observer some crispy pop-cornies ... 

The very superb heating conditions with no cloud, and purer air in absence of any offsetting CAA anywhere is probably going to cap temp early, and then bounce around on the thermometer, this steals 10ths of a degree as it erodes it's way up to 77 in few spots maybe.

Basically ...anatomy of utopia
