Supposed to have a mantown weekend in Fryeburg on the Saco later this month. Will there even be water in it?

Dragging canoes is such fun, especially when they're loaded with duffle, food and drink.  Learned all about that on Allagash Stream going to (and 4 days later, dragging back from) Allagash Lake.

Fryeburg fair?

We usually go camping around that time, but one of the guys has a friend with a house on the Saco. May just rent it and go canoeing.

We used to go there and on the Androscoggin, but haven't recently.

Yeah hopefully we get some rain up there.

Even in September the coastline isn’t favored for any severe tomorrow..Are there ever scenarios where they don’t weaken and die out before they get here?

The coast is never really "favored" versus interior, but the best time of year is typically Aug/early Sept. for coastal areas lol

Sniffed this out firstly on Monday!  Some knew

   ...Northeast...
   A wave of low pressure is forecast to develop over eastern PA early
   in the day, translating northeastward along the front and into ME by
   late afternoon. Stronger heating and steep low-level lapse rates
   should develop from VA into eastern PA/NJ and into interior southern
   New England, with MLCAPE around 1500 J/kg as an areal average.

   As the warm air mass develops and accelerates north ahead of the
   cold front, both instability and shear parameter space will become
   favorable for severe storms, including supercell potential. A line
   of storms is expected by 17 to 18Z, from eastern PA toward the
   Hudson Valley, expanding N/S and pushing east through the afternoon.
   Given 40-50 kt effective deep-layer shear and enhanced low-level
   shear with the midday surface theta-e surge, the initial storm mode
   may be cellular along the boundary, with a brief tornado or two
   possible along with some hail. Damaging winds are then most likely
   as outflows merge, and spread east across the remainder of the
   region through late afternoon.

One big difference tomorrow between the NAM and GFS is the difference in lapse rate in the lowest km. This could be the difference in getting damaging wind gusts that are more scattered/concentrated versus localized.  

:blink:  any consideration to the nada model ?

What are you guys seeing with these new temp/dewpoint sensors? I haven't seen much discussion on this, but they seem significantly cooler than the legacy sensors. And MUCH higher on humidity, at least in the overnight/mornings. All of a sudden, it's 100% humidity all the time at night around here. Never used to see ASOS throw up a 100% humidity before.

Current Events

I don't believe it's happened yet. Last I heard there was an issue at one of the test sites that caused them to pause the replacement plan, but that was like 9-10 months ago back when we weren't trying to cut NOAA's already meager funding in half.

EDIT: Looks like they have begun to roll some out to southern region stations.

EDIT2: On second look, it looks like they are done with half of the stations. Around here: BDL, HFD, IJD, ACK, BED, BOS, BVY, FIT, HYA, MVY, ORH, TAN, PVD, UUU, WST, and PYM.

Yes, they haven't updated the spreadsheet since July 1, so I suspect they've swapped out most by this point. Just wondering if there's been any cool bias? I would argue, yes, but I'm wondering if anyone else has noticed this. It looks like the stations that were running on legacy sensors did much better for heat early on this summer versus the stations that had swapped in the new sensors.

I wondered if we are going to have to temper our expectations for heat. Might be difficult to beat some of these 90s-2020s records if the sensors were reading hot. We've grown accustomed to breaking 100-150 year old records left and right. May not be the case moving forward.
