    This is why looking at "1km simulated reflectivity" for a start time is a bad idea. Gotta look at 1-hr QPF. We're still on track.

    Yes, please and thank you... 2 GFS slam dunks in a row.

    lol, that's always been there, it's fine. Its beam blockage of the radar itself from Bull Run Mountain.

    Manassas airport reporting -SN

    That's an all-timer WSW for St.Mary's county.

    We're getting there. DCA TDWR is showing under 5000 now. Should start to see reports of flakes from south to north starting with Manassas, Woodbridge etc. soon.

    The 1/3rd rule is actually pretty darn accurate. Wetbulb = Temp*.66 + DewPt*.33 is scary good for how simple it is.

    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.

    oof

    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!

    slower and way more amped
