brooklynwx99 Posted January 2, 2022 Share Posted January 2, 2022 the NAM made a huge shift at 500mb, namely in the positive interaction of the NS rather than a negative confluent push, as we had seen a couple of days ago the initial vort is more amped, which is great, but the NS is now helping to turn heights in a more southerly direction. look at the wind bards S of LI: almost due S from WSW last run. this drastically changes the angle of the PVA 4 8 Link to comment Share on other sites More sharing options...

wawarriors4 Posted January 2, 2022 Share Posted January 2, 2022 LWX AFD Dramatic shifts in guidance over the past 12 hours for a potential snowstorm tonight through midday Monday for the southern half of our CWA, bisecting very close to the major metropolitan areas. Digging H5 trough over the southern plains will amplify today, cut-off an upper low tonight over the Carolinas, then go negative tilt as it crosses the mid-Atlantic coast Monday morning. The reflection at the surface will be the development of low pressure, rapidly deepening and tightening tonight over the southeast US to a position over Cape Hatteras by daybreak Monday. At the same time, cold Canadian air will quickly filter in aloft, bringing H85 temps well below 0C for much of the entire CWA by 12Z Monday. 00Z GFS, ECMWF, NAM all have at least advisory level snowfall accumulations essentially south of I-66/US-50. 05Z NBM, which was followed closely in development of snowfall accumulations this morning, dampens the largest snowfall contributor -- the GFS, and splits the difference between that model and the lesser accumulating NAM. Because of the large variations and the dramatic shift in guidance, advisories have been issued west of I-95 where the precipitation onset will start shortly after midnight tonight, and watches issued along and E of I-95. There will be a tight gradient of snowfall accumulation north of the Nation's Capital, and potential warnings and advisories will most certainly be modified as guidance hopefully converges with a solution over the next 12 hours. The most likely snowfall forecast should be used with caution, with probabilities of higher amounts, towards the 90th percentile, should strongly be considered for planning purposes. Please continue to check back as we modify this forecast in the coming hours. 2 1 Link to comment Share on other sites More sharing options...
