Watches up for OKX zones now.

Best December since '09 I'd say for combo of snow and cold.

1.3 inches after the first hour of snow.

Vis is maybe 1/2 mile in this band over the panhandle of CT. Accumulating nicely.

Snowing in Greenwich

As far as I can tell just these so far: BGR, CAR, FVE, HUL, and MLT.

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.

Hopefully the ASOS service life extension program makes the network more reliable. It's 30 years old at this point and really starting to show its age.

Too bad this rain didn't sink south about 12 hours earlier could have had a lot more records set. This kind of cold is pretty rare. BDL smashed a record that stood for 103 years by 7 degrees.

Wind changed in the 2000s when ASOS transitioned from cup and vane anemometers to the ultrasonic ones. That change only affected gusts as the averaging period was reduced from 5 to 3 seconds to match the WMO standard made possible by using a more responsive instrument.

I think it still is a 5-minute average sampled every 10 seconds. That 2-minute/5-second thing looks more like wind measurements.

It's an AWOS-3P. I've long suspected it only has passive shielding because of how quickly it races out ahead of everyone else in the morning. I know it has a little elevation being 400 ft. ASL, but so do other stations. For example this morning at 8 AM, SNC was the warmest temp in the state by 2° showing 86 when the next warmest DXR and BDL were only 84 and most everywhere else upper-70s/low-80s.

Yep.

Suspect it's a non-aspirated or poorly shielded temp sensor.

90 at EWR already let's go!!!!
