I'm in the northwest quadrant of Monroe county, riding the edge that separates the heavier stuff from the lighter, 2 - 4" seems a safe bet at the moment. I haven't seen latest guidance from the short range's. Edited March 6, 2023 by TheComet 2 Link to comment Share on other sites More sharing options...

Admin MaineJay Posted March 6, 2023 Author Admin Share Posted March 6, 2023 WPC Quote Probabilistic Heavy Snow and Icing Discussion NWS Weather Prediction Center College Park MD 212 PM EST Mon Mar 06 2023 Valid 00Z Tue Mar 07 2023 - 00Z Fri Mar 10 2023 ...Northern Mid-Atlantic... Day 1... A narrow but potent 500mb shortwave trough exiting the Great Lakes tonight has its sights set on the northern Mid-Atlantic tonight. The setup features the left exit region of a 150 knot 250 mb jet streak positioned over northern PA, northern NJ, and into southern NY with the nose of a strong 100 knot 500mb jet aimed at these same locations. At lower levels, a surface and 850mb low will travel along a warm front that will be situated from the upper OH Valley to the Chesapeake Bay. This will allow for the three aforementioned regions above (northern PA, northern NJ, and into southern NY) to be located just north of the 850mb low track. In addition, along and north of the warm front, CAMs are indicating a strengthening 850-700mb front via increasing WAA aloft, along with a steady surge of 850-700mb moisture. These ingredients are ideal for strong mesoscale-driven banding at the nose of the 500mb jet and north of the warm front, which along with the bulk of the snowfall occurring at night (daytime becomes more difficult for accumulations with an ever rising sun angle this time of year), gives rise to the concern for an intense band of heavy snowfall that could setup from northern PA to both northern NJ and the NYC metro area by early Tuesday morning. It was telling that the WPC Snowband Probability Tracker showed a good consensus for snowfall rates as high as 2-2.5"/hr starting close to the Buffalo metro area this evening, then moving across northern PA and along the PA/NY border between 00-06Z Tuesday. These kind of rates can lead to rapid accumulation on all surfaces, as well as near whiteout conditions for those traveling in these areas. Where guidance begins to differ is by the early morning hours Tuesday. Some guidance shows the 850-700mb front beginning to undergo frontolysis or there is too much low-mid level dry air at the onset to overcome as the shield of precipitation approaches northern NJ and the NYC metro, which despite the strong synoptic scale lift and sufficient moisture present, would cause snowfall rates to wain and perhaps struggle to get above 1"/hr. However, the favorable ingredients mentioned does provide a floor for this event, or in other words, enough lift and moisture is present to still cause locally heavy accumulations between 06-12Z Tuesday. Due to the best mesoscale drivers being positioned over northern PA, it is here where guidance is coming into better agreement on heavier totals. Latest forecasts suggest totals of 4-8" have grown in confidence north of I-80 in northern PA with totals closer to that 4-6" range within reach closer to the Delaware Valley in eastern PA. It is in these areas where the experimental PWSSI shows 40-50% probabilities for Minor impacts Monday night. Once you cross the Delaware River, the waning frontogenetic support could lead 1-3" with localized amounts >4" in northern NJ and could encroach into the NYC metro area. The affected areas in eastern PA, northern NJ, and perhaps into the NYC metro could see enough snow accumulation to make for a slushy AM commute on Tuesday, making for what could be a slick and treacherous AM rush hour for motorists. 1 1 1 Link to comment Share on other sites More sharing options...

Admin MaineJay Posted March 6, 2023 Author Admin Share Posted March 6, 2023 Meso disco just issued. Quote Mesoscale Discussion 0256 NWS Storm Prediction Center Norman OK 0551 PM CST Mon Mar 06 2023 Areas affected...Parts of northern PA and western NY Concerning...Heavy snow Valid 062351Z - 070345Z SUMMARY...Heavy snow with rates up to 1" per hour is possible this evening across parts of northern Pennsylvania and western New York. DISCUSSION...Strong zonal flow is present across the eastern Great Lakes region with an embedded shortwave trough traveling eastward, and the associated DCVA and frontogenesis are providing the necessary lift for precipitation. Additionally, a good vertical juxtaposition between the lift and the dendritic growth zone should support heavy snow. Per mesoanalysis and surface observations, wet-bulb temps are in the 32-36F range, which can support heavy snow given the expected heavy precipitation rates. Indeed, heavy snow was reported at the KBFD METAR site in northwestern Pennsylvania in the last hour. With time, the precipitation is expected to translate east-southeastward and weaken as the evening progresses. ..Supinie.. 03/06/2023 ...Please see www.spc.noaa.gov for graphic product...
