  1. Like i said earlier, The globals have a better handle on it, But looking at H5 from 12z on the euro to 18z, Some differences. 18z 12z
  2. Those snow maps from a day or two ago had today's, and Mondays storm totals in them.
  3. I don't think anyone would toss the 12z EPS, Have to shave off 3" here from today's.
  4. Still time for changes. LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... An active Pacific Jet and strengthening upper level blocking to our northeast will lead to a crowded upper level pattern as several upper level features traverse the CONUS early next week. These features will catch up to each other underneath the block, morphing into an upper low that will spin over head through the middle of the week. At the surface low pressure will track from the Mid-Atlantic towards Nova Scotia Sunday night into Tuesday and then retrograde and stall near the Gulf of Maine Tuesday night into Wednesday. Current guidance keeps the heaviest precipitation offshore with the potential for periods of light precipitation Sunday night into Wednesday. The components the low pressure system include a trough over Texas, a short wave that moved into the Pacific NW this morning, and another short wave moving into British Columbia tonight. These features eventually consolidate into an upper low over the Northeast under a blocking high over the Labrador Sea. Ensemble sensitivity experiments out of Stony Brook highlight the interaction of the latter two waves with the trough over Texas with the greatest sensitivity. Although there has been a notable shift farther offshore with the 02.12Z ensemble suite, one of the features is still in the data sparse Pacific along with CIPS Analogs showing a few analog systems that tracked close enough to bring appreciable snowfall. Therefore, have increased PoPs above NBM guidance to account for the potential of future track adjustments as well as the persistence of the upper low near overhead. At this time there is potential for periods of snow from Sunday night through Wednesday morning with highest chances along the coast shifting towards northern and eastern zones Tuesday into Wednesday morning as the low retrogrades westward. Impacts wise, amounts look to be light each day with mainly intermittent periods of snow covered roads. There also remains potential that snow will mix with rain at times near the coast with highs in the mid 30s. High pressure will nose into the region from the north Thursday and Friday with signs of another low pressure system developing near the East Coast next weekend.
  5. I think right now the global models seem to be handling this better, Still a lot of moving parts in the flow to this one, A subtle change can have bigger implications.
  6. The approach of a mid/upper level shortwave currently analyzed over the mid-MS River Valley and low pressure forecast to develop over eastern NC due to a residual baroclinic zone will bring another round of wintry precipitation to portions of the Northeast and New England late on day 1 (Sunday) through day 3 (Tuesday). A lack of deep phasing and separation between the mid-level wave and low will keep precipitation relatively light over portions of PA/interior NY where a few inches of snow are forecast. But as the low approaches the Gulf of Maine, it will slow or even retrograde back to the west/southwest as its caught up in the deepening/closing off mid-level energy. This could support a prolonged period of snow across coastal NH to much of Maine in th day 2/3 time-frame, though there remains considerable uncertainty in the evolution and QPF. Deterministic runs of the latest guidance did trend upward, particularly for Maine where there is a signal for winter storm criteria to be met or exceeded. However, given the uncertainty and model spread still, the blend favored the ECENS/ECMWF runs. This system bears watching.
  7. Starts monday and snows until weds night up here................
  8. That's a solid 8" for here on the 12z Euro, I would hit that.
  9. Looks like the 12z Euro with another tic or two NW again this run.
  10. Someone else can post for down there, It still has today's in there so i wanted those out.
  11. Just did the driveway, 2.2" additional so we finish at 5.0" storm total.
