I imagine the QPF vs snow depth measurements are going to be distorted by IP. Whatever fluffy stuff falls first is going to be compacted by sleet on top.

anyone able to access weather.gov is doing so via a certificate other than weather.gov's invalid one, not everyone has that option

weather.gov's CA certificate has been invalid for months, leaving the site totally inaccessible to many

Clara Peller would ask, "Where's the blocking?!?"

we need more \ and less / Earlier, there were comments about ULL capture of a surface low. FWIW, I recall that happening with the Janury 20, 1978 nor'easter.

How do various current wx station models handle normally-varying wind directions? Do any update the direction display many times per second? Many models display what the wind direction happened to be when that instrument was last queried. As most here probably know, air does not always move in a straight line. A real-time wind vane will show the direction changing frequently, for example, anything from W to N, or even beyond, when the average direction is NW. To learn, I acquired a low-end station because the maker was practically giving them away. When I know the predominant direction to be NW, this unit sometimes displays S or E or others because the wind happened to swirl a bit when the vane was last queried. A few seconds later, the next query might return a very different direction. It's basically useless for determining the predominant direction. Some better stations quote a 2-second sampling rate, which seems too low to me, perhaps because I am used to a wired, real-time vane.

I ended up acquiring replacement parts from d8apro.com and repairing the unit.

Is this a permanent change at the Accuweather channel, or did they give all their OCMs Thanksgiving Week off? BTW, windiest day here in awhile. Helped me test my refurbished anemometer.

Something I'm not observing are humans on the Accuweather TV Channel. Lately whenever I've tuned in it's been just automated graphics, even during morning and evening prime time.

Killington and Stowe have opened for skiing. May the snow soon come a few hundred miles south.

I like seeing juicy Pacific systems come ashore near LA, as is progged for this weekend. When other conditions are right, those have produced some of our biggest snows about a week later. May that pattern continue into the coming colder months.

Eric Wilhelm's focus is on Ohio, but he does a nice job explaining the reasoning behind his winter forecast for the larger region. He explains the acronym sea of QBO, IOD, ENSO, etc. He posted the full winter forecast version on youtube today. https://www.wfmj.com/clip/15520187/erics-annual-winter-forecast

maxed at 40, making today's avg 34.5 Nov 22 last year had similar cold

29 for the low here, first freeze of the season. This brief cold shot reminds me of what most of November 1977 was like. Repeated frontal passages followed by cold stratocumulus skies.

Topped out at 44, some 5 to 10 degrees lower than forecast. Growing season very likely to end tonight, but wind will prevent temp from dropping far below freezing.

down to 36 at 10 pm, feels like I-95 gets first freeze tonight

From AFDLWX of 223 PM EST Thu Nov 6 2025 "The airmass moving into the region Monday night is going to be extremely cold, possibly approaching some of the coldest temps ever sampled for the Tuesday 12Z IAD sounding. The GFS and ECMWF both show the potential for 500mb temps to be at or colder than -35C."

though the lat lon puts it in East Columbia

ah, added to USGS 16 mins after the event, centered in Riverside, MD

it's not showing up on the USGS list, but that sure felt like a small quake

Small earthquake in Central MD a moment ago?

DIPAs. The closest we're gonna get is Miller Lite.

Could not find a wired version on the Ambient site. Does one exist? I'd like to avoid the cost of installing batteries repeatedly. Around here, people want $500 to bring a ladder and climb to the roof. Siting wind instruments closer to the ground won't give reliable readings.
