We are on the southern edge, but it looks like a real fun event for NJ and NYC. It really blows up as it approaches the coast and isn't the razor thin line we've seen on guidance. definitely some great signals on the hi-res guidance. The Hi-Res Windows (particularly the NMMB and ARW2) look awesome Link to comment Share on other sites More sharing options...
CAPE Posted January 30, 2019 Share Posted January 30, 2019 Getting a last hurrah band on the back edge and its finally all snow and snowing hard. Won't last long enough to amount to anything though. Link to comment Share on other sites More sharing options...
CAPE Posted January 30, 2019 Share Posted January 30, 2019 HRRR really blows up that squall line tomorrow as it hits the coast. Snow squall chase at Rehoboth? Who wants to meet me at Dogfish? Link to comment Share on other sites More sharing options...

Fozz Posted January 30, 2019 Share Posted January 30, 2019 I remember a few impressive snow squalls in Feb 2013. It was otherwise an uneventful winter (other than my SNE snow chase), but those squalls were pretty cool... looked like mini-blizzards. Link to comment Share on other sites More sharing options...

They didn't do our streets and it's like 1-2" of slush. Going to be a sheet of ice tomorrow morning. Mine too. Pretty dense. I’ll try to get a water content later.

snowfan Posted January 30, 2019 Share Posted January 30, 2019 I'm always hesitant to buy into the idea that strong squalls make it this far east, but I'm interested in tomorrow. Most guidance shows it and the 0Z 3K NAM looks really good. Link to comment Share on other sites More sharing options...

CAPE Posted January 30, 2019 Share Posted January 30, 2019 From Mount Holly- The biggest impacts from the arctic front that will be felt tomorrow are the winds and the potential for snow squalls. It looks like a pretty good set up for convective snow showers and even snow squalls near and just behind the front. There is significant low and mid level frontogenesis and low stability in the low and mid levels (as evidenced both by CAPE values in model soundings and low equivalent potential vorticity values). The one aspect that is lacking is moisture, which will be quite limited. None the less, think there is a potential, primarily in the 15 to 21Z time frame. Have included a mention of snow showers in the forecast, but will not be issuing any winter weather advisories as it would be better covered by snow squall warnings, if the squalls develop. If they do develop, expect localized significant impacts including a quick accumulation, reduced visibility, and locally higher winds. Link to comment Share on other sites More sharing options...
mattb65 Posted January 30, 2019 Share Posted January 30, 2019 3k drops the temp from 31 to 17 when the snow squall rolls through at 1pm through the DC metro, hope it's onto something. Link to comment Share on other sites More sharing options...

Bob Chill Posted January 30, 2019 Share Posted January 30, 2019 I'm going to walk the dog tomorrow when the front blows through. Temps could drop 10 degress or more in less than 30 mins.

WEATHER53 Posted January 30, 2019 Share Posted January 30, 2019 I was on the low end of this, 1.6” (now it’s 25 and flash as* freezin’) Drove thru some 1.5ph stuff but that never got here. Still fun,and more to come, then warm some, then more fun. Link to comment Share on other sites More sharing options...

wxdude64 Posted January 30, 2019 Share Posted January 30, 2019 Glad all y'all north got to be 'in the game' today. Sadly, I played the "white rain game" here. Sheesh. But the mountains above and around me at about 2500 feet are absolutely beautiful. Currently 15.8/8.6 with WNW wind at 11 gusting 19 mph, WC 3/-1.

arlwx Posted January 30, 2019 Share Posted January 30, 2019 The Rt.123/I-495 snow fence held up long enough for those west and north of there to keep almost all the s***! Now all I have to worry about is the flashfreeze icing. Down to 24 at DCA at 4 am. OPM probably threw the feds a bone so they can see the ice this morning and hopefully not get into wrecks. Same for Arlington: Weds, Jan. 30: All APS schools and offices will open 2 hours late. Extended Day will also open 2 hours late and morning field trips are canceled. Essential personnel and food service workers should report to work at their scheduled time. All other employees should report to work two hours past their usual start time. We will reconfirm or update this status by 6:00 am. Ditto for Alexandria public schools: Important Message WEATHER ALERT: For Wednesday, January 30, 2019, all ACPS schools and offices are opening two hours late. Kindergarten through grade 12 and Virginia Preschool Initiative (VPI) students report two hours later than regular opening time. Morning pre-K programs (Early Childhood Special Education and Preschoolers Learning Together) report two hours later than regular opening time, and dismiss one hour later than usual. Afternoon pre-K reports one hour later than regular opening time and is dismissed at the regular time. All non-essential personnel should report two hours later than their regular time. Essential personnel report at regular time. To complete the inner suburb set, Falls Church: FCCPSAlert Falls Church City Public Schools will operate on a 2-hour delay, Wednesday, January 30th. Day Care will open at 8 am. No Drop-Ins will be accepted. As a result of the delay, there will be no Early Release except for some students at Jessie Thackrey Preschool. We will continue to monitor weather overnight and adjust schedule if needed by 6am. To complete the inner set: MoCO and PG 2-hour delays No announcement from DCPS (and probably won't be one) Link to comment Share on other sites More sharing options...
arlwx Posted January 30, 2019 Share Posted January 30, 2019 And for those of you thinking OPM caved yesterday: Not all Feds live east and south of the RT 123/I495 snow fence. Some commute from far west of Dulles, which hit freezing at 3 pm. Leaving DC at 1:30, those in Sterling barely had time to get home first. I think OPM also feared a repeat of Carmageddon (26 Jan 2011), where I bolted early and barely could see through the ice forming on my windshield to cross the Potomac and slide home. Those who waited for OPM to make the call were SOL. Link to comment Share on other sites More sharing options...

MillvilleWx Posted January 30, 2019 Share Posted January 30, 2019 Snow Squall Warning might be broken out if the current Hi Res depiction for this afternoon comes true. Northern crew could get whacked pretty good with steep low level lapse rates mixing to 700mb. Gusts into the 40's pretty likely if that occurs with maybe even near 50 mph.
