First Winter Storm Warning in U.S Sept 2014 (snowing, season, dewpoint)

Current Watches and Warnings. Winter Storm Warning now extended into South Dakota. That's the Black Hill area. 4-10" expected.

Shocking to see winter weather warnings at this time of year. Today it was 90 degrees where I live, and humid. I doubt we will see any snow here until January, even then very little of it.

Check out who's reporting snow right now. Im assuming the Dakota hills are enhancing moisture there. That's a large area of snow for this time of yr there!




Any snowflakes in North Platte Nebraska before midnight would be our earliest on record. Current record: Trace of snow on 9/12/1989

Yesterday saw the earliest snow in Great Falls, MT since 1992 when it fell in Aug. Since 1892 only 6 times has it snowed earlier than Sep 9!

6:30am. Look how far south the freezing line at 850mb is!

Also who's reporting snow and wind chill in 20s & 30s. It feels like upper 30s in Western Nebraska!

You can see the snow is falling around or north where the 850mb freezing line is. Except above 7000 feet of course like there in Wyoming.

Custer, South Dakota this morning.

5-7" of snow has fallen and is still falling in South Dakota.

Rapid City didn't get past 45°F for the max yesterday which was a record for the date.

Rapid City record earliest measurable snow is Sep. 13, 1970. It's been snowing there this morning. Lets see if it accumulated!

Just remember... You're witnessing and alive to see & hear the earliest accumulating snows for some areas! That is exciting!


Hill City South Dakota Looks like some low ratios there. (cement)

Always fun to see actual OBS of surface & atmosphere.

Here's the actual sounding from 12z in Rapid City this morning. Note... 850mb temps were -2.3C. Elevation at Rapid City is 3160. 12z is 6am. It was snowing there at the time.

It was below freezing in all layers except the very surface it was 33F/0.4C

I don't see many before Sept 15th

This morning on the news they were saying only a possibility of snow sticking to grassy areas, less than a quarter inch. By 9 a.m. tomorrow, no more chance of snow. So if there are flakes, that will make 4 months to the day since the last snow, the "freak" Mother's Day snow. Gawd, I need to move back to California
