OceanStWx Posted March 4, 2019 Share Posted March 4, 2019 Watch the echoes down over NJ. See the speed and direction they are taking (right at the heart of SNE). 700 mb front is probably not moving much, but 850 will tick NW some as the low approaches. But that precip over NJ will be slamming into a wall. That's the 40-50kt flags Will was pointing out yesterday. 3 Link to comment Share on other sites More sharing options...
PowderBeard Posted March 4, 2019 Share Posted March 4, 2019 Almost 2" down since 8pm. Going to bust low baring a massive change. Link to comment Share on other sites More sharing options...
wxsniss Posted March 4, 2019 Share Posted March 4, 2019 Box 10pm AFD: Presently, H9-7 frontogenesis / deformation coincident with high radar returns over the Delmarva Peninsula into NJ while H7-6 frontogenesis was contributing to a SW-NE snow band over PA into Upstate NY. These two element coinciding and colliding over S New England as we move towards the morning hours beneath broader diffluence aloft with the right rear quadrant of an H3 jet streak aloft, concern of higher QPF values and snowfall amounts subsequent. There are low probabilities within the HREF of +12" amounts over E MA, while forecast model omega values within the dendritic growth zone are notably stronger into the early morning hours on Monday, values upwards of 30 microbars per second as low-level convergent forcing is squeezed by upstream forcing yielded by mid-level impulse energy sweeping through the base of the tropospheric polar vortex, i.e., an arctic front. But, as alluded to by the prior forecaster, there are some snow- fall losses ongoing as 2m temperatures continue to cool with snow onset, the column continues to moisten, dry air becomes less of a concern ... altogether, initial issues with snowfall accumulation. Opted to blend the latest high-res forecast with the prior. This pushes a bigger area of 8 to 10 inches with localized heavier amounts that could push slightly above 10 inches. 1 Link to comment Share on other sites More sharing options...
wxmanmitch Posted March 4, 2019 Share Posted March 4, 2019 Solid moderate snow with dendrites, 25° F. Looks like around 2" new. Nice little 700 mb frontogenesis band FTW. Link to comment Share on other sites More sharing options...

butterfish55 Posted March 4, 2019 Share Posted March 4, 2019 Just took the dog out. 32.8, and little over an inch so far. Some of the heaviest (weight, not rate) snow I've see. The trees and bushes are drooping so much with only an inch. Can't imagine that we won't see widespread power outages around here once the heavy stuff starts.

rnaude241 Posted March 4, 2019 Share Posted March 4, 2019 Dumping snow here. Hoping the R/S line holds of most of the night. Link to comment Share on other sites More sharing options...
NeonPeon Posted March 4, 2019 Share Posted March 4, 2019 Moderate to heavy now. .5" of the wettest snow that exists. Luckily there is not much wind with this. Someone will get inches of this paste and limbs will snap anyway, though. I'm glad I'm going to bed soon. Id prefer to remember things like this.

That makes sense. I assumed it was just upper level difluence but the directional circulation to it makes sense. So hypothetically if the region of interest is in the left entrance, would the jet streak have the opposite (i.e. inhibiting effect) due to sinking the warmer/moist air on the equatorward side?
