DISCUSSION...A long-duration snow event is underway across parts of NE and IA this morning. A somewhat more organized precipitation band has recently developed from eastern NE into west-central IA, within a zone of enhanced frontogenesis within the 900-800 mb layer. This band may continue to progress eastward in conjunction with a mid/upper-level shortwave trough (and related surface low) currently moving eastward across the central Plains.=20 Light to moderate snow has been ongoing this morning across much of IA, while observations and recent dual-pol data from KOAX indicate that a changeover from freezing rain/drizzle to snow is underway from Omaha to near Lincoln, NE. Snow rates within the ongoing band (and any additional organized bands that develop) may approach or exceed 1 inch per hour at times this morning. Farther south into far southeast NE and northwest MO, a residual warm layer may result in a mix of precipitation types, though brief periods of moderate to heavy snow rates could occur where a full changeover to snow can be maintained. ...Dean.. 11/29/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_xbQDpEVIsKt-KhYC-QrxV32d0LuvNY8Ec4-9x5U55q2iyhxqopK0Mvwr92ycBmkZlNswUmZU= 8gRN-qXU64r25LWkwE$ for graphic product...
