Not that I've heard of! They rise pretty quickly. They're made mostly out of styrofoam. At Sterling, they call the Dulles tower to let them know they're releasing them.

It's launched from the weather service office just outside of Dulles. They launch at 0z (7pm) and 12z (7am) daily.

Donut is holding around 6000ft...

Correct. The models had this pretty well outlayed. Euro especially. Those wishing for a 9pm start time were in for a disappointment. Totally agree on the cold to start! Rather have instant stickage than waiting for rates to overcome.

0z balloon from Sterling shows very dry air in the low levels of the atmosphere. It will take awhile for those snowflakes to make it to the surface. Talking hours.

0z sounding out of Baltimore ()Morgan State Univ) for CoURAGE

Nothing like flashing a new operating system to a dead snow depth sensor on a sunday afternoon before a pasting.

The skew-t plotting is horrible, but it doesn't the temperature label is the red numbers between 850-900.

This was about an hour ago out of BWI but dang is it dry up there.

Backyard pools aren't really big enough to have a large impact on humidity / dew points unless your a few feet from it. Anything more than 15ft horizontally and 4 ft vertically won't notice. Regarding Dew Point. The humidity sensor (and therefore dew point) is the first instrument to go bad on a home weather station. The hygrometer we use on mesonet stations and at ASOS sites need frequent calibration.

Heavy Snow in Silver Spring. Grill tops yes, roads no.

Thermometers in general are pretty darn accurate to at least the nearest 1°F, even the worst ones are good to 1°C. If someone tells me, "well it was xx° at my house!" I generally believe them. The only ones I don't often trust is The bi-metallic strip coil thermometers you find on big round porch thermometers.

Today was a day. 23 degrees, with 15G40 mph winds and snow showers / BLSN. All while needing bare hands to touch nuts and bolts for installation. Fun times!

Thunder is very quality with the inversion.

January: Medium/ Long Range: May the Force be with Us....
wxmeddler replied to Weather Will's topic in Mid Atlantic
Well since the only thing it knows is history, its learned that we generally just get screwed. -
Light onshore flow from the bay will do that

My Prediction: Radar is gonna look worse than that surface. Even the 3KM NAM has dew pt depressions 7-10F in the AM. That said, it's gonna stick on roads that aren't treated.

Tiny bit of a shortwave at 500 moving through with some elevated moisture levels and clouds. Might put a pause on our cooling for a 3-4 hours. Still, longest night of the year. Someone is gonna get single digits east of the Blue Ridge.

Rates can overcome any ground temp. We just don't have the rates. Visibility hasn't dropped below a mile at DMW or FDK Edit: Which isn't surprising. Pretty abysmal thermodynamics going on.
