Ltrain Posted January 23, 2016 Share Posted January 23, 2016 Just measured 3" in about 10 spots. Temp fluctuating between 23° and 22°. Winds are definitely starting to get going here near the bay. I am going to get yellowed for awhile it looks like. Even heavier stuff moving almost due north from the CaroliCarolinas right up the Bay. Gonna be a fun night.

87storms Posted January 23, 2016 Share Posted January 23, 2016 re the last hrrr image. i think i've learned that it's hard to rely on a model that is shifting all over the place. i think in general the thing to take from it is that there is going to be a "deathband" at some point. where it sets up, who the hell knows.

Mrs.J Posted January 23, 2016 Share Posted January 23, 2016 Just got in from our second clear off of the driveway. The snow was a bit heavier than the first time, and the wind is picking up. Cleared off about another 3". Previous clear off was about 2 1/2". Link to comment Share on other sites More sharing options...

CoastalWx Posted January 23, 2016 Share Posted January 23, 2016 SUMMARY...A BAND OF HEAVY SNOW WILL DEVELOP NORTHWARD ACROSS WESTERN VA INTO EASTERN WV AND WESTERN MD OVER THE NEXT FEW HOURS. SNOWFALL RATES OF 1-2 INCHES PER HR /WITH LOCALIZED RATES UPWARDS OF 2-3 INCHES PER HR/ WILL BE POSSIBLE. DISCUSSION...WATER-VAPOR IMAGERY AND THE REGIONAL RADAR MOSAIC SUGGEST A BAND OF HEAVY SNOW IS BLOSSOMING ACROSS THE MCD AREA IN RESPONSE TO INCREASING LARGE-SCALE ASCENT...AS AN IMPULSE OVER THE SRN APPALACHIANS CONTINUES TO ROTATE AROUND THE PERIPHERY OF THE MATURING UPPER TROUGH. STRENGTHENING WAA AT LOW/MID LEVELS...IN COMBINATION WITH ENHANCED FRONTOGENETIC CIRCULATIONS...WILL FAVOR A BAND OF HEAVY SNOWFALL RATES THIS EVENING. ADDITIONALLY...LAST VISIBLE IMAGES PRIOR TO NIGHTFALL INDICATED SMALL CONVECTIVE ELEMENTS WITHIN THIS GROWING SNOW BAND...FAVORING ENHANCED RATES. DUAL-POL ZDR AND KDP DATA FROM KFCX CONFIRM THAT DEEPER/STRONGER CRYSTAL GENERATION ALOFT IS OVERSPREADING THE REGION...IN RESPONSE TO INCREASING ASCENT WITHIN THE -10 TO -20 C LAYER. KRLX ALSO DEPICTS SUCH SIGNATURES TO ITS EAST AND NORTHEAST. EFFICIENT CRYSTAL GENERATION AND THEN AGGREGATION BENEATH THAT LAYER WILL FAVOR VERY HEAVY SNOW AT TIMES...WITH LOCALIZED RATES UPWARDS OF 3 INCHES PER HOUR AND LOW VISIBILITIES THIS EVENING. http://www.spc.noaa.gov/products/md/md0055.html Notice the greens taking over as more and more flakes develop.

Bob Chill Posted January 23, 2016 Share Posted January 23, 2016 not gonna lie, breeze is kicking up. i'm legitimately concerned about power going out. the wind, this early in the storm, is taking me by surprise. will only get more wicked. blizzard warning seems like a very good call at this point. this is a big deal storm. At least it's super dry and cold snow. I shoveled a path down my driveway just for fun. I could have done it with a leaf blower. Colorado powder going on. I'm not worried about loading up the trees and lines yet. One guest and it all blows off. 4" at 8pm. Link to comment Share on other sites More sharing options...

SoCoWx Posted January 23, 2016 Share Posted January 23, 2016 Since the sleet arrived so much earlier than progged in Richmond, is there any idea if it will change back over sooner, too? Link to comment Share on other sites More sharing options...
phil882 Posted January 23, 2016 Share Posted January 23, 2016 re the last hrrr image. i think i've learned that it's hard to rely on a model that is shifting all over the place. i think in general the thing to take from it is that there is going to be a "deathband" at some point. where it sets up, who the hell knows. Exactly... that is beyond the predictability of the high resolution guidance. However, the fact that you see such an impressive band run after run gives you confidence it will develop at some point, and somebody is in for near record accumulations, and possibly >3" per hour snowfall rates. It may be more useful to think of it probabilistically... where a large region in N VA, MD, and PA has the chance (30-50%) of getting under the 3" per hour snowfall band. As the band begins to set up, it will become more clear who really is going to jackpot from this event. This guidance is available from the NCAR ensemble, which showed the highest probabilities of such a band off to the north and west of DC metro... but DC proper still has a 20-30% chance of getting under it. url: http://www.image.ucar.edu/wrfdart/ensemble/images.php?d=2016012200&f=snow_neprob_3.0&r=MATL Link to comment Share on other sites More sharing options...

Colorado powder going on. I'm not worried about loading up the trees and lines yet. One guest and it all blows off. 4" at 8pm. True. I'm more concerned about the direct impacts of the wind on the lines not so much from the weight of the snow. I know you've said you lived in Colorado. This is definitely pure powder just like there.

JonathanW Posted January 23, 2016 Share Posted January 23, 2016 What's the best radar app out there? For Android -- Radarscope. For PC -- I'm partial to the GRLevelX products. GR2Analyst Edition is best for high resolution and volume displays. GRLevel3 is a great program for displaying the standard suite of NWS NEXRAD products, including dual-pol products.

Mrs.J Posted January 23, 2016 Share Posted January 23, 2016 Did't think we had that much. but I live in a south facing apartment. We face East/West. The drive way is the east facing. The wind is coming from behind our row and whipping around the side. We may be getting more drifting pumping up those clear off totals. Deck only looks to be about 4", it faces West and is getting the winds. Link to comment Share on other sites More sharing options...
PhineasC Posted January 23, 2016 Share Posted January 23, 2016 My guess is N and NW of DC is where 3' potential lies. Yes, that's where it always is no matter what the models show. They always jackpot unless it is a southern storm that is already fringing DCA. A huge band will set up over the northern tier tomorrow and dump for hours and hours while DCA and SE gets moderate snow. Eventually the band will swing through and give DC some sloppy seconds but by that time it will have blown its load. Link to comment Share on other sites More sharing options...

Stormpc Posted January 23, 2016 Share Posted January 23, 2016 Shoveled 2nd time. Heavier icy snow this time. Rimed flakes falling now. Too tired to take more than a half dozen measurements but we here in PW have between 5.5-6. Thats what I got. Leesburg, Jeb or Bristow confirm?

CoastalWx Posted January 23, 2016 Share Posted January 23, 2016 Is it just me, or is that mix zone getting closer to NOVA per the latest CC loops? It will get a bit further north and have everyone panic, but as the mid level lows nuke near and east of DC, that will then collapse east later tonight.
