Phil Posted November 11, 2019 Author Report Share Posted November 11, 2019 Dropped to 24*F here the other night. The 21*F at Dulles was the coldest low this early in the season since 1976 when it hit 19*F, IIRC. Another cold shot moves in this week..could be just as cold if not colder. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...
Phil Posted November 12, 2019 Author Report Share Posted November 12, 2019 First snowflakes of the season today. Precip built back in under CAA, and there was just enough wet bulb potential to pull it off. Gusty too, station registered 40mph while the snow was falling. No accumulation. And no diurnal temp cycle either..should drop into the low/mid 20s tonight and tomorrow night.

Andie Posted November 13, 2019 Report Share Posted November 13, 2019 Low of 21* this morning. Clear and sunny now. We had a tiny amt. of sleet, but the sleet and snow went to central and south Texas. A real treat for them. Hill Country is gorgeous in the snow. Looking forward to whether North Texas will see any action on the Thanksgivng break. 1 Quote Before You Diagnose Yourself With Depression or Low Self-Esteem,...First Make Sure You Are Not In Fact, Just Surrounded By A$$holes. “If I owned Texas and Hell, I would rent out Texas and live in Hell.” Gen.

Phil Posted November 15, 2019 Author Report Share Posted November 15, 2019 Dulles dropped to 17*F with that last cold shot. Not bad. Hit 21*F here. Though I suppose if I relocated my temp/humidity sensor to a better location it might have been closer to 19*F..it’s currently on my porch roof under a pine tree which is pretty sh*tty/not recommended. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted November 23, 2019 Author Report Share Posted November 23, 2019 Looks like some cold weather possible in early December..some flakes/mix possible too.

Phil Posted November 23, 2019 Author Report Share Posted November 23, 2019 Some more rain tonight in the meantime. Maybe 0.5”-0.8” followed by a breezy day tomorrow..gusts 35-40mph off the mountains as cold/dry air is advected under/just ahead of pressure rises at the peak of the diurnal cycle. FWIW, the Wednesday before Thanksgiving could be really gnarly pending the evolution of that system as it ejects out of the Rockies. Given the -NAO in tandem with the Bermuda High and the depth of that trough over the Rockies..my hunch is there’s gonna be some tight a** pressure gradients with this one. A very anomalous, “combative” situation in the atmosphere. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...
Phil Posted November 24, 2019 Author Report Share Posted November 24, 2019 Wind is blowing harder than I expected this morning, funneling right through the Cabin John Creek Valley.

Phil Posted November 26, 2019 Author Report Share Posted November 26, 2019 Wednesday evening/overnight looks like solid wind advisory criteria along/west of the Fall Line at least. Little precip to stabilize the boundary layer during the day then a heavy pressure surge/CAA regime initiates at sundown +/- 1hr with a non saturated profile in place. Thanksgiving travelers might be in for some white knuckle driving.

Phil Posted November 27, 2019 Author Report Share Posted November 27, 2019 Some intense wind fields being depicted on the HRRR/NAM/GFS for late tonight and tomorrow. The 06z ECMWF was less ridiculous but still has ~ 60kts overhead @ 850mb by 10-11z. If the 12z run bumps up to 65-70kts, LWX would pull the trigger for the I-95 corridor, I’d think. Pressure rises/dry advection occurs overnight behind the cold front, which should cross the I-95 corridor around 00z +/- 1hr. More of a westerly component than a NWerly one initially which might keep the best mixing along/north of a line from Leesburg to Dulles to DCA. But I’m not 100% sure on this.

Wxmidatlantic Posted November 27, 2019 Report Share Posted November 27, 2019 Second Winter Storm digs SE 84 to 120 hrs. Transfer and secondary development off DELMARVA seems likely. There may be a few pingers or wet snow to herald in the precip shield Saturday or 0Z Sunday. Thermal profiles need to be monitored. Keep in mind we have a neutral SPO. The hammer drops late.

Wxmidatlantic Posted November 27, 2019 Report Share Posted November 27, 2019 More importantly is the the pressure combined with thermal gradient of the current storm in the Great Lakes.
