Same principle applied to citrus growers in FL when they spray water on their produce during freezing threats. The water helps protect the citrus from freezing. Very counterintuitive.

Temp just rose to 29/28dp. Was at 28 since the start at 05:15. Sleet only atm - hoping that inbound band does the needy...

Radar hole down around Hburg not filling in. Really lightening up here in Vienna - pixie dust temps have not budged any since starting at 05:15. Now 28/27dp. About 3" otg atm

32/18 - down to freezing w/o the dp rising a tick...

33/18 - Just came back from getting "food" for my Kubota (see avatar). The atmosphere has that special feeling outside... Slight breeze from the NNE and variable.

NWS radar over TN/NC is intense. Large cells of deep red, nearly at the black level on the legend. That's more like a summer-time event than Feb. If even a percentage of that holds, the sn+ rates tomorrow am will be exciting.

Taking a stab at something here... Look at all the flood watches in the lower Ohio and Mississippi valleys. Impressive for any system, let alone in Feb. Factoring in the forecast precip field maxes out to our west on the windward side of the mts, it appears the moisture fetch is going to be inbound to the DELMARVA more from the WSW than what we traditionally see from the SW up through the Carolinas. Suppose that's due to the monster ridge off the SE coast. With the fetch taking more of an arched route, does that give the HP NE of the GLs more time to "cool" the the air mass, which in turn allows the CAD to hold longer? We typically see the SE fetches scour out the CAD faster than what's projected this time around. HM commented earlier today on the rare combination of phenomena that's setting the table for this event. Is the above part of that?

Interesting how the WSW is still cutoff sharply at the M-D. Based on the consensus being dialed in across the models and runs, expected NWS to expand it further N by now, if not at the initial posting. Maybe the next update later this afternoon will see a northward expansion.

hahah PBR... right up there with Iron City, Hudepohl, and old dog light (Old Milwaukee Light). The combination brings back memories of college - at least the parts I remember when not in a drunken stupor. Then moving to Germany 3 years after college brought an awaking to what REAL bier is all about... never forget my first real Pils... was a spiritual event.

I drink OJ in the morning. Never really need a kick to get going. Guess I got used to getting up and getting going working construction to get through college. Working with power tools gets your attention. The ice coffee that I succumbed to 2x was from a wood vender in Japan. The wife of the owner brought us ice coffee when we placed a big order. (you wouldn't have believed this place - it was right out of some history novel). She was about 150 years old and I didn't want to offend her, so I gulped it down in one nauseating swig. Was all I could do to keep up upchucking it. When we went back to pickup the order a week later she brought us more. That was the last time anything resembling coffee entered my digestion system. Don't even like coffee tasting chocolate etc. But to those consignors like yourself, enjoy.

Fully agree - Heineken here is a much different taste than in Europe. Still, even the European version w/o all the additives is blah. Especially with so many alternatives in Europe to pick from. Never understood the appeal other than they have a strong marketing department.

Moved this here out of respect to storm mode, but suspect some others may be interested... Care to provide the link to the soundings app. Also, is there an easy to read tutorial on the soundings chart with some examples. Understand the warm nose concept etc, but would be great to see some examples of where the profile represents "normal" snow, heavy snow, sleet, freezing rain etc... Thanks

Don't drink coffee, can't stand it. Only had it twice in my life and it was a near death experience both times - ice coffee in Japan (didn't want to offend the offerer - long story). Always wondered... Is drinking decaf for a coffee lover akin to trying to stomach alcohol free bier?

Remember that event well. My family and I departed on VD to move to Bangkok. Was chaos at IAD to say the least. However, that event was a very prolonged sleet storm the likes of which we rarely get here if anywhere. The HP to the NE of the GL was much stronger and the event was a combo of CAD with a W to E LP that ran a stationary front that helped preserve the CAD. While there's no doubt a lot of CAD on this one, the BL lifts to the NE eventually on the models. What may make this interesting is if the secondary forms off the DELMARVA has some posters mentioned earlier today. That may not help us much around here, but there's the hint of a decent band setting up to the NE of PSU. If only that were to happen down by the OBX...

1/2" sn and then flipped to sleet about 15 mins ago. Lt pingers now and 31/28dp.... Fun while it lasted, although sleet is better than rain any day...

Ok - reasonable for the DELMARVA. What's the threshold for a HECS and BECS? Propose something on the order of 24"+ is HECS territory and 30"+ is a BECS... Add winds over 30 kts to the mix and drop the thresholds 6" each. Winds 50kts and over with anything over 12" is a BECS. Blizzard of 78 in the midwest was definitely a BECS.

Loved Bill in the early days of the "Not Ready For Prime Time Players" on SNL. However, his ego got the best of him and earned him the unenviable title of one of the most difficult to work with in Hollywood. Loved Caddyshack when it came out. Then read, from multiple sources, about what an arsh he was to work with on the set. By many accounts the persona Bill portrays during get first half of Snow Day is fairly accurate to the real thing... I'll take the plain ole slapstick comedy of Tim Conway and Harvey Corman any day of the week and twice on Sunday. Ditto for Red Skelton in his heyday, but realize the comparison of Bill to the others is apples to oranges (or sour gooseberries).

Beg to offer a 3rd... 3.) Move to San Diego to the land of perpetual boring weather where every day is like the last and the next, and leave this forum to those who really enjoy the best of whatever Mother Nature can muster.

Beg to differ 04... Chinese is too easily translated. It was more like sanskrit or hieroglyphics. Think that author needs to read more and post less. Or draft a message, sleep on it and then delete it....

Indeed re the inversion. NWS put out an Air Quality Alert for NE MD. Must be as a result of the inversion. Don't see that so often this time of year.

Yup - indeed. Moved here in 85 - lived overseas off and on, but during the time I've been here in NOVA this may be tops on the cold spectrum (but I missed 96 and some other events). Already up to a balmy 27 and rising rapidly.

Got down to 7 here - up to 9 already.... Nippy out there.

Interesting how the NWS expanded the WWA to the sw and west this late in the game (was posted at 3:26pm), just as the western edge started to pivot to the east. Seems a bit late unless they know something we don't. I don't detect any back filling on the radar, but someone earlier did mention the HRR showed some potential wraparound later, albeit for the eastern side of the beltway and east of there. (the DC beltway)

Been dead calm here just NW of Vienna on Lawyers Rd. since the onset. Had a slight breeze from the NW when I left work at 14:00. Work is adjacent to rt28 near interchange of 28 and McLearen about 1/2 mile from the Dulles main N/S runway. That said, it's just about always breezy at work being adjacent to 28, the airport and out in the open. Never had any rain there at all. Went from a few flurries, to SN-, to SN in about 20 mins. Just had a great band here at home for about 15 mins that deposited about a 1/2". Must have been one of the 35dbz bands showing up on NEXRAD. Still dead calm out.

Think this passage will be as dynamic as the one in 2015? That was a pretty intense 20 mins. Reminded me of some of the events we had in Ohio growing up. One difference between 2015 and Tuesday appears to be the pace at which it comes through. If I recall correctly 2015 zoomed through as the front raced across from the midwest eastward across the DELMARVA. Tuesday's frontal passage seems much slower, but that will also give it a longer dwell time over the area.
