Excessive rainfall may produce locally considerable flash flooding over parts of the northwestern Gulf Coast, lower Mississippi River Valley, and Deep South through Thursday. Potential Tropical Cyclone One is forecast to become a tropical storm (Arthur) as it moves along or just off the northwestern Gulf coast through Wednesday. An outbreak of severe weather is forecast in the Midwest Wednesday. Read More >
Overview
|
A long duration winter storm tracked across the region Friday night and Saturday. Widespread snowfall amounts over 8" were common, with some locations receiving over a foot of snow! This will likely go down as one of the highest snowfall events for any year for the month of November in eastern IA, northwest IL, and northeast MO. Numerous accidents including a few jackknifed semis on I-80 and I-74 and several road closures occurred with this event. Thank you to our many volunteer observers for your reports!

Dubuque averages a 10+" snow event about once every two years based on the last 30 years.
Moline: The total of 9.2" made this the 4th snowiest system in meteorological autumn (September-November) on record for the city (using 3-day totals). The top three are the November 25-26, 2018 blizzard (13.8"), the November 20-21, 2015 event (9.9"), and November 29-30, 1974 event (9.8").

Moline saw more snow with this single event than it saw in the entirety of the previous winter (8.2")!
This one system resulted in November 2025 and Meteorological Autumn 2025 both being top ten snowiest on record for Dubuque and Moline. Climate Summary

| Figure 1: Satellite water vapor imagery with the zone between the orange lines having been favored for strong lift and persistent banded snow. This positioning, just north of a dry slot and within the system developing "comma-head", is often a ripe zone for heavy precipitation and was indeed the case during the mid-afternoon into early evening on November 29. | Figure 2: November 29, 3 PM Graphicast issued by our office highlighting this zone of heavy snow development. | |

| Figure 3: DVN 18Z (noon CST) weather balloon data referred to as a sounding, showing a deeply saturated profile with high atmospheric moisture (precipitable water greater than one half inch) and steep lapse rates above that within the dendritic growth zone (larger snow flake development). The saturated somewhat isothermal temperature profile between -4C and -8C in the lowest several thousand feet favored the "sticking" of snowflakes to each other (aggregation), helping for larger flake size. | Figure 4: Mean sea level pressure (MSLP) from RAP model analysis. This depicts the surface low pressure passing across our southern area. This is a favorable path for our northern CWA to see large snowfall amounts if the temperature profiles are favorable, which they were. In the southern CWA, there was copious moisture and instability ahead of the low pressure with still a cold enough profile to support heavy snow as well, especially on the morning and early afternoon of November 29. | Figure 5: Dew point from RAP model analysis. This shows the dew points increasing ahead of and within the system, but values still staying for the most part below freezing, which with cooled pavement allowed for quick accumulations and limited melting. |
