Weather Summary for Upper Mississippi River Valley
National Weather Service La Crosse WI
310 AM CDT Tue Sep 20 2016
Last evening was mostly clear with the exception of extreme
southwest Wisconsin where a line of scattered thunderstorms slowly
moved out of the region. Temperatures quickly dropped into the
upper 50s to mid 60s after sunset with light and variable wind.
For the rest of the overnight, expect areas of dense fog along and
east of the Mississippi River Valley where visibility below one
quarter mile is possible at times. Once the fog dissipates, much
of today will be dry and warmer with high temperatures from the
upper 70s to lower 80s.
Shower and thunderstorms return to the region late tonight through
Thursday as a frontal boundary stalls out across the region. At
least two rounds of potentially heavy rain are possible through
mid-week and could result in localized flooding. The strongest
storms will also be capable of producing hail and strong wind.
High temperatures on Wednesday are going to reach into the mid 70s
to lower 80s, and then upper 60s to upper 70s for Thursday.
