  1. Yes & they confirmed that they are confident in the forecast this morning.
  2. The 6z GFS still looks good for most from around I-81 north & west.
  3. CTP has a strongly worded forecast discussion this morning: && .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/... *Significant winter storm potential with heavy snow and minor ice accumulation possible Sunday afternoon through Monday afternoon Coldest minT will be Saturday night with lows in the negative to positive single digits from north to south. Light winds under sfc high should cap wind chills at -5 to -10F over the northern mtns or above advisory criteria. A closed mid-level low pivoting across the Gulf Coast early Sunday morning will begin to lift northeast and take on a negative tilt across the southern Appalachians Sunday afternoon and then race northeast to be over NJ by 12Z Monday. This will be accompanied by an increasingly coupled jet structure downstream of the pivoting trough, with intense ascent through diffluence aiding in the development and then strengthening of a low pressure system moving north to a nearly stacked position by the end of D3. The guidance has come into much better agreement with the placement of this low lifting roughly along the I-95 corridor. As this low initially develops, mid-level confluence over the Mid-Atlantic will help reinforce a wedge of high pressure down the east side of the Appalachians in a typical Cold Air Damming (CAD) setup. As the low strengthens, moisture will surge northwestward behind robust isentropic lift and likely produce a period of moderate to heavy snow (WAA thump) early Sunday night (00-06Z Mon). Mixed thermal profiles and possible dry slot are in play into early Monday morning to the southeast of I-99/80 which could transition snow to ice over the southeast part of the CWA. While there are still some details to resolve, there is a strong enough model signal to issue a well-collaborated winter storm watch for most of the CWA from 18Z Sunday to 18Z Monday. The multi-model/blended QPF and SLRs indicate potential for 6" or more of snow with a minor ice glaze also possible across the southeast 1/3 of the area. Deformation snow appears to linger over the northern part of CPA through Monday morning. The expected snowfall btwn 12-18Z Monday was not included in the storm total with this cycle given that it is beyond the set time window. Expect cold/gusty NW flow to take over Monday night with deformation snow transition to lake effect/upslope snow showers into Tuesday morning.
  4. Lol, so when @sauss06 & I cross the bridge to Harrisburg just a few minutes away, we don’t need to “Watch” for snow. I’m sure the Watch will be extended at some point, but it is just LOL how whoever issued this county list has no clue on how the Harrisburg metro area works.
  5. Wrap around light snow then continues Monday early afternoon.
  6. I have a difficult time believing the LSV would be raining as the low jumps to the east at this hour.
  7. The low still has the strange non-traditional jump from the central Chesapeake to north central MD.
  8. Here are the close ups from the 0z Euro as it approaches our latitude.
  9. Here is the 0z GEFS. Very nice mean low track from the DelMarVa to Southern NJ coast.
  10. Thankfully our teams playoff games are earlier in the day before the wind kicks in. If the Eagles somehow upset the Bucs while snow onset is on my doorstep…I will be out of control! If the more likely scenario happens that the Bucs knock the Eagles out, then at least the snow will quickly cheer me up!
  11. @canderson Check this wind on the 0z GFS Wind speed & gusts! Just imagine Front St. tree damage!
  12. 0z GFS Snow map for most of CTP is similar to 18z Kuchera & 10-1 are similar. Harrisburg area is around 8 inches of snow again this run.
  13. Wrap around light snow still ongoing at 18z Monday early afternoon.
  14. By Monday morning the low is over Long Island with wrap around back into most of CTP.
  15. Yes, the track was in line with other models from today. Long way to go…. On to the ICON?
