I think every October I can remember at least has had a light accum at 1500ft base of the ski resort here. Sometimes in town but 1500ft seems annual...it might just be a coating that melts by 9am but it happens. It’s really hard to get strong CAA that time of year and not have some upslope response. Yeah I'd have to think at minimum he will see those graupel squalls that change to snowflakes after several minutes of good intensity on some cold CAA cyclonic flow airmass that would coat things up.....but he's likely to get something more real in October there.

From looking at the Randolph data, I think your climo is very similar to 1500ft at my office. My daytime obs are likely going to be very similar with you. At night once home it’ll be different, ha. Good excuse to just stay at work, I guess. LOL Link to comment Share on other sites More sharing options...

It hadn't snowed for days at this point (that thin layer on top of the older layer was about 3 days old....the thicker older layer was over a week old), but it stuck around like it does in mid-winter and Thanksgiving itself was the coldest November day on record at ORH (and likely many other stationsin New England)....you just don't normally see the snow stick around like that in November. Most November snow melts within a day or two down in SNE or even most NNE lowlands....Randolph, NH at 1500 ft is obviously different. Yeah that month was nuts. Thanksgiving 2018 was a better winter holiday than half the Christmas’ this decade. Down under 1,000ft up here it’s very rare to go full cover starting like the 10th of Nov and never relenting. I think even the end of October was real cold... I met up with Oceanstwx for a beer and it was whatever day those SNE tornados happened near BOS... but like that next day it was snowing steadily in October even down low. The SPC guys in town from Oklahoma for that severe conference we’re loving it. Link to comment Share on other sites More sharing options...

Yeah I’d be shocked if he doesn’t get at least one squall worth a transient inch in October. There’s always a cold pool that brings like a 0.14” QPF to 1.0” snow/graupel mix to the hills on the NW flank of New England, even if it melts like an hour later when the sun comes back out and you lose the wet-bulb process with temps going back from 33F to 43F again.

I don't feel like we've seen this type of continuous frost threat pattern in September in a while. Odds are that I'll escape tomorrow's frost (I'd give it 2 out of 3) but not 10 days from now with its below zero 850s. Median here for 1st frost is 9/19, so one next week would be close to that. 12Z GFS has no precip thru day 14 for my area. Link to comment Share on other sites More sharing options...

Typhoon Tip Posted September 11, 2020 Share Posted September 11, 2020 This operational GFS run seems to try and 'back' winter in from the Maritimes ... eroding backward against the western ridge... each trough ablation carves the westerlies a little more SW... It's bringing an early winter over eastern Canada for starters...but for our proximity to that region of the hemisphere is sideswiping us with gradually more then just swiping across subsequent all three ... The last hard freezes. But the problem I have with that is particular to the GFS. It keeps engineering these ginormous gaps in the hypsometric depths to thickness ratios. The thickness will by physics always be less than the geo -p hgts, but... not 30 dam. wow ... 576 dm heights with a 546 thickness cutting underneath is appearing suspiciously too anxious to cool of the lower troposphere. I bet that normalizes some... That said, it's nesting error really...because the gist of early and heavy cold signaling is something that fits with recent decadal trends for autumns... ( springs, too in the lagged seasonal thing..), the former of which then gets compensated once the gradient really gets sloped later in DJF .. blah blab. Cross the bridge.. but in the mean time, it's like the GFS sniffs it out but then oversells it at the same time. interesting... Link to comment Share on other sites More sharing options...
snowman21 Posted September 11, 2020 Share Posted September 11, 2020 October snow isn't exactly unheard of even in SNE. In the last 30 Octobers, PVD has seen snow 4 times, BDR 6 times, BDL 7 times, BOS 8 times, and ORH 10 times. Link to comment Share on other sites More sharing options...

You are south of them and they are at least as high as you. Was it CAA from the SW, like wrapping around an upper low?
