Yeah, this could overperform here if the moisture holds on long enough... forecast winds are just about perfect for upslope for my neighborhood (~020 for a solid 8 hour period)

1.1" snow today, 3.8" for the month, 9" season.

Got 0.3" for a season total of 7.9".

I was 12 in the Blizzard of '78 in E MA, when my parents took their only vacation without us EVER - to Bermuda. They were stuck there for an extra week, and we had off school for almost 2 weeks. Plow took 3 days to get to our street. We had fun with the babysitter, jumping off our roof into the drifts, and had to XC ski to the corner store to get whatever they had left. Now that was fun!

Amazing how a tiny difference in trajectory creates such different outcomes for the major EC cities. But the majority seem to track the heavy snow inland. I remember 12/5/03 well, had a 6 yo and a 4 yo kid and we built a VERY large snow fort once I was able to get home from work.

So it's probably the social media effect then. I remember driving from MA to FL in the late winter/early spring of 2010... a few days after the big storms and a few months before moving to CO. Never seen such snowbanks in MD/VA!!

Is it just me and social media, or has the East Coast had more than its share of winter epics the last 6-7 years? When I lived in MA, we had a big storm every 2-3 years, but I don't remember having anywhere near this many. Plus there has been a lot more cold Ohio Valley and east the past few years, that's certain.

Banding is nuts. 1 inch here at 1015 PM, looks like places less than 10 miles south and west got 5-6. Mountains even more impressive, with 3 and a half inches at Loveland Ski area but a foot just a few miles away. Lake effect indeed. Maybe the Chatfield Reservoir effect? EDIT: snow stake at bottom of Loveland Ski area says 8 inches. The SNOTEL site had 3 and a half. So ??

Very nice! We got 4.5" here, a good surprise. It's weird because there is a new COCORAHS station just a mile SW of me that measured 8". No way we got any more than 6" anywhere in the yard, even by "ski area measuring technique".

Honestly, I don't know if this ongoing fire situation was anything anyone could "prepare for": - High density, essentially urban to suburban area (this was not isolated homes surrounded by burnable vegetation) just downwind of foothills/prairie - Open space, mainly grass, to the west (not forested, just prairie) where it started - Driest 6 months in recorded weather history for the immediate area - Winds coming down the canyons with widespread, prolonged gusts over 80 MPH- a little ember can go miles with that kind of wind - NWS assessment as late as 3 AM today was mixed as far as high wind threat- the AFDs told you how much trouble they were having with their decisions AND IT'S FREAKING DECEMBER 30!! Just an enormous tragedy.

This could be fun, compared to what we've had so far. Could triple the <1 inch we've had season to date... even if we take 50% of the predicted QPF 48 hours out, which was on target for many of last year's storms. If I need to shovel for more than 20 minutes, I'll call it a win. Then again, this could be one of those 25:1 "storms" where you can clear the snow in a moment with a leaf blower.

Danger, Will Robinson... it's dihydrogen monoxide. Very hazardous.

Finally something to talk about in the mountains, and cause for celebration for skiers in the next two weeks. 12-18 inches through Christmas at the Summit County areas, more as you go NW and SW, and possibility of more next week. ValpoVike, keep us posted! (any other posters on this board in the mountains?)

That is really interesting. When I lived in MA (most of my life) it was sometimes even a bit later, like end of January, as the ocean tempered things a little earlier in the season. The Denver climatology curve is really dead-flat in terms of average temps from now through mid-January. Anecdotally, some of the lowest temps IMBY occur later in the season (early Feb) when there is more snow cover, but are balanced by slightly higher highs.

Late post: 0.9" snow Friday morning. First of the season. Let 'er rip...

If I had a nickel for every time I saw this in the BOU AFD, I wouldn't need the CARES Act... our snowfall forecast for the Denver metro continues to decrease as most guidance has trended much drier.

Yup, we dropped 21 degrees (from 58 to 37) from 3 to 4 PM with the ever-interesting "BLDU" at APA, another 9 degrees the hour after that, and now it's in the upper teens.

Yeah, looking OK but so far away... My sense is that the QPF is not so much underdone with mesoscale features as that the variability is underdone. Commonly, the typical upslope places (along the Peak-to-Peak, Boulder) get more than predicted, while downsloping places (often Fort Collins, CO Spgs) get less than predicted. Today I looked at the July-Nov climate data for most reporting stations in AZ, NM and CO. The only place that got less precipitation than Denver was Yuma, AZ. How about that.

As my wife's Brooklyn relatives would say, looks like a flying sorcerer.

I'm beginning to think "above normal precipitation" means a relative humidity of 50%. Heck, I'd be excited for a little frost at this point.

It takes a certain length of time of freezing weather (? weeks) to reset the clock on most plants. They are vulnerable if it freezes very hard (<15 F soon after the 60s) in the fall, or if there is a warmup followed by a hard freeze in April/May. This happens with some regularity. Between that and chronic dryness, the Front Range is a tough place to be a tree. On the bright side, this past Spring's moisture and lack of hard freezes produced some of the best fruit crops in many years... apples from our tree are still in the fridge.

Also- these conversations are pretty great and the nerd index is an order of magnitude higher than most other subforums, just sayin'...

Thanks raindancewx! How/where do you get these data? Would love to play around with them some.

Thinking climatologically: how to get data for the driest 4-month, 5-month, 6-month periods for reporting stations? DEN had <1 inch of rain the past 4 months combined- this has got to be up there, if such a record exists.

and good to be wrong... though DEN still has its streak going, most of the metro area saw a nice 0.1-0.2" last evening. Felt downright weird walking around in it.
