1100 PM CST Thu Feb 19 2026
Areas affected...Northeast Iowa...extreme southeast Minnesota...and
southwest Wisconsin
Concerning...Heavy snow
Valid 200500Z - 201000Z
SUMMARY...Heavy snow will develop/spread across northeast Iowa into
southwest Wisconsin over the next several hours. Snow rates may
exceed 1 inch per hour at times.
DISCUSSION...Southwest-northeast oriented band of moderate-heavy
snow persists across IA late this evening. This band is expected to
spread/develop across northeast IA into southwest WI as the 700mb
low advances across eastern IA into southern WI by 12z. Latest
radar/satellite imagery suggest multiple heavier bands will begin to
coalesce along an axis from near ALO-PDC-VOK as the primary midlevel
circulation shifts east over the next few hours. While heavy snow
with rates around 1 inch per hour are expected, a very narrow zone
of mixed precipitation may exist along the eastern fringe of this
corridor briefly before transitioning to snow.
