Richboro PA Posted January 26, 2011 Share Posted January 26, 2011 FOX 29 in Philly just stated 12-16 additional inches this evening. I dont see that happening, but I do see 6-12 from everything I have read Link to comment Share on other sites More sharing options...
famartin Posted January 26, 2011 Share Posted January 26, 2011 I have never heard that terminology "indefinite sky" thats interesting...any idea what the actual rate of snowfall is there right now causing that? "Indefinite" is I guess the layman's translation for the actual encoding which is "vertical visibility" (VV). Its common in heavy snow, and in fog. It comes out in the METAR as VVxxx where xxx is distance from the ground in hundreds of feet. In other words, VV001 is vertical visibility 100 feet.

RU848789 Posted January 26, 2011 Share Posted January 26, 2011 New Mt Holly AFD NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 334 PM EST WED JAN 26 2011 .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... -- Changed Discussion --THE WARM AIR ADVECTION SNOWS ARE ON THE WANE AFTER DEPOSITING UP TO 6 INCHES IN CHESTER AND MONTGOMERY COUNTIES TODAY. WHAT WILL TURN INTO QUITE AN INTERESTING EVENT IS SEEN ON RADAR AND SATELLITE APPROACHING OUR AREA FROM THE SOUTHWEST. NUMEROUS LIGHTNING STRIKES ARE OCCURRING IN VIRGINIA THIS AFTERNOON A PROGRESSIVE UPPER-LEVEL TROUGH OVER THE WRN CAROLINAS TAKES ON A NEGATIVE TILT. IT WILL EJECT NEWD ACROSS THE MID ATLANTIC REGION THIS EVENING. AS THIS OCCURS...THE SURFACE LOW WILL MOVE NEWD TOWARD A POSITION S-SE OF LONG ISLAND BY 03Z. MODEL FORECAST SOUNDINGS INDICATE THERMODYNAMIC PROFILES ALONG AND S OF A LINE FROM NRN VA TO CNTRL NJ THAT WILL INITIALLY SUPPORT MIXED PRECIPITATION. HOWEVER...THE COMBINATION OF STRONG DEEP LAYER ASCENT AND STRENGTHENING LOW-LEVEL CAA OCCURRING IN THE WAKE OF THE DEPARTING SURFACE LOW WILL FAVOR A QUICK TRANSITION TO SNOW AS THE PRIMARY SHIELD OF PRECIPITATION TRANSLATES NEWD DURING THE LATE AFTERNOON INTO THE EARLY NIGHT. THE CONVECTION WILL BE CROSSING OUR AREA BETWEEN 5 AND 8 PM. DON`T BE ALARMED IF YOU HEAR A RUMBLE OF THUNDER. SNOWFALL RATES IN THIS CONVECTION COULD EASILY REACH 1 TO 2 INCHES PER HOUR WITH NEAR WHITEOUT CONDITIONS POSSIBLE. IT IS ADVISABLE TO AVOID TRAVEL THIS EVENING IF AT ALL POSSIBLE. WHEN ALL IS SAID AND DONE, THE LOW WILL PULL OFF TO THE NORTHEAST LATER TONIGHT AND THE SNOW WILL END FROM SOUTHWEST TO NORTHEAST BETWEEN 2 AND 5 AM. CURRENT TEMPERATURES RANGE FROM THE UPPER 20S AND LOWER 30S NORTH TO THE MID AND UPPER 30S SOUTH. LOWS OVERNIGHT WILL DROP TO AROUND 20 NORTH TO AROUND 30 SOUTH. IT APPEARS AS IF THE I-95 CORRIDOR WILL BE IN LINE FOR THE MAXIMUM ACCUMULATIONS IN THIS EVENINGS SNOW. WE SHOULD EASILY BE ABLE TO MEASURE 8 TO 12 INCHES BEFORE IT BEGINS TO TAPER OFF AROUND OR SHORTLY AFTER MIDNIGHT.-- End Changed Discussion -- I have to admit I'm not sure if they mean 8-12" more snow or not. Most of their area has received 4-6" of snowfall so far, so 8-12" total would be an additional 4-6", whereas that discussion certainly makes it sounds like there could be 1-2"/hour snows for ~9 hours or did they mean 1-2" per hour snows would only be a subset of the time from 5-8 pm to 2-5 am? Anyone care to clarify that? The total snowfall maps seem to support the former (8-12" total), but that disco certainly sounds like more than 4-6" more snow to fall. When I left Metuchen for work around 11:30 am, we had 4.0" of new snow. My wife kindly measured 1.5" of snow on the back table on our deck that I cleared off a little while ago, so I'll put our total at 5.5" for Part One of the storm. Quite an appetizer - hope the main course is overfiling (Monty Pythonesque - "one wafer thin mint" - kind of overfilling, lol). Right now we have a mix of snow and sleet falling relatively lightly here in Rahway and 33F (Weather bug says it's 30F in Pway and 31F in NB - sounds inconsistent with 33F in RY - not sure whether to trust W-bug).

Richboro PA Posted January 26, 2011 Share Posted January 26, 2011 That was for the Chester County area, and that's TOTAL accumulation (including the 5" on the ground from this AM) I must have misread it then.

Blizzard-on-GFS Posted January 26, 2011 Share Posted January 26, 2011 HRR, WRF, and NAM all agree that an intense mesoscale band will set up from baltimore to trenton. I have never seen rates progged like this.... This is simply crazy. It's going to be like a an intense thunderstorm with snow. People are going to be shocked to wake up to locally 20". What a band...

NJHurricane Posted January 26, 2011 Author Share Posted January 26, 2011 raining in parts of Md per the Mid atlantic thread...changeover back to snow is chasing just behind the first big batch of heavier echoes moving from SW to NE.

mranger48 Posted January 26, 2011 Share Posted January 26, 2011 31.6 degrees in Brick, NJ....was it supposed to be dropping below freezing this early here? btw.was 32.7 at around 3 oclock, so I'm assuming this is the beginning of the steady drop in temps?

Richboro PA Posted January 26, 2011 Share Posted January 26, 2011 9-13 in the City and suburbs. It was just posted on the main site at 4pm. I got my information from their facebook page FOX 29 Here is an advance look at what the forecast could look like on the 5 pm news - it is a blog from our weather desk. The totals and timing look similar to what we reported at 11 am, unless you live in Chester County (where they are now looking at an additional 12-16 inches).

noctilucent Posted January 26, 2011 Share Posted January 26, 2011 31.6 degrees in Brick, NJ....was it supposed to be dropping below freezing this early here? btw.was 32.7 at around 3 oclock, so I'm assuming this is the beginning of the steady drop in temps? (at least at the surface ) Over here in Bucks County, the temp was about 34.5 at 1 PM. It then started fluctuating between 32.5 and 33 between 2 and 3:30 PM. It is currently 31.6 here also. So, based on what I have observed, a slow, steady drop in temperatures has commenced over the past 30 minutes. Link to comment Share on other sites More sharing options...
