It's often a bad model but it's really good in these type of storms. It's like the NAM in that it there's use for it in certain situations. 1 Link to comment Share on other sites More sharing options...

wthrmn654 Posted February 23 Share Posted February 23 Mesoscale Discussion 0115 NWS Storm Prediction Center Norman OK 0624 PM CST Sun Feb 22 2026 Areas affected...New York City into Southern New England Concerning...Heavy snow Valid 230024Z - 230530Z SUMMARY...A long-duration moderate/heavy snowfall event will increasingly impact NYC into parts of southern New England this evening into Monday morning. 1-2 inch per hour snowfall rates will be likely, particularly after midnight EST. DISCUSSION...Recent regional radar imagery from the northern Mid-Atlantic/southern New England shows a band of moderate to heavy snow moving slowly northward into Long Island. Already, recent surface observations reported 1 inch in the last hour at Islip, LaGuardia, and JFK. This band should continue to impact parts of southern New England this evening. The highest snowfall rates will at least initially remain near the coast. With time, the 994 mb low analyzed off the Mid-Atlantic coast will deepen, particularly after 11 pm/midnight EST. This will eventually promote a broader zone of stronger isentropic ascent that will promote more widespread moderate/heavy snow farther north. Surface winds will also concurrently increase with the deepening of the low. Blizzard conditions will be possible late this evening into Monday morning. ..Wendt.. 02/23/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BOX...OKX...ALY...

RU848789 Posted February 23 Share Posted February 23 1 hour ago, RU848789 said: As of 6 pm, we have 2.5" of snow, so another 1" last hour it's snowing at moderate+ whatever that is. Temp still 31F. Very pretty snow coating everything including the trees since the first inch or so was pretty wet and it stuck, despite ~15 mph winds with gusts to 20-25 mph now. As of 7 pm, we have 4.0" of snow, so 1.5" last hour as it's been snowing close to heavily (not crazy heavy, but visibility maybe 3/8 of a mile. Temp still 31F. Just finished my first shoveling and it wasn't too bad - bottom snow layer was wet but snow falling now is somewhat drier, but still packs. 2 Link to comment Share on other sites More sharing options...
