Area Forecast Discussion
National Weather Service La Crosse WI
635 PM CDT Wed Sep 5 2018

.SHORT TERM...(This evening through Thursday)
Issued at 307 PM CDT Wed Sep 5 2018

Latest 20z surface analysis indicates cold front extending from
southern Ontario Canada into southern Iowa and high pressure over
the Northern Plains and southern Canadian prairies. Along the
cold front...showers were occurring along the front per mosaic
radar. Visible satellite imagery showed clouds along the surface
front back into southeast Minnesota...much of Iowa and Wisconsin.

the 05.12z GFS/ECMWF/NAM are in good agreement in building surface
ridge into the Upper Great Lakes Region tonight into Thursday.
This will advect drier airmass and slightly cooler temperatures
into the forecast tonight into Thursday. Skies should clear from
north to south tonight and become mostly sunny for the Thursday.
High temperatures are expected slightly below normal with highs
rising into the upper 60s to middle 70s.

.LONG TERM...(Thursday night through Wednesday)
Issued at 307 PM CDT Wed Sep 5 2018

Next concern is potential for fog across the area Thursday night.
The deterministic models are in good agreement in building the
center of the surface ridge over the forecast area. With light
winds and clear skies...a strong inversion develops after 06z
Friday. With boundary layer moistening...areas fog will be
possible to develop in low lying areas and river valleys.

Saturday night through Wednesday...Main forecast concerns are shower
and thunderstorm possibilities Sunday into Monday. The 05.12z
GFS/ECMWF/GEM are in decent agreement with developing west to
east zonal flow aloft through the period. The deterministic models
suggest shortwave trough and remnants of Gordon to track into the
Great Lakes Region Sunday into Monday. With vertical motion and
moisture convergence associated with the shortwave trough/remnants
of Gordon west and southeast of forecast area. At this time...do
not expect any showers or thunderstorms across the forecast area
Sunday into Monday. With surface ridge in control over the Great
Lakes Region. This will provide dry weather across the forecast
area Tuesday into Wednesday. Temperatures are expected to be near
to slightly above normal Monday into Wednesday.

&&

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 622 PM CDT Wed Sep 5 2018

Stubborn low cloud deck continues to slowly shift east and should
clear both TAF sites by 06z, leaving VFR conditions for the
remainder of the TAF period. Otherwise, generally light surface
winds from the northeast will persist through the TAF period.
Surface winds overnight should remain high enough to hold off any
fog development tonight.

.HYDROLOGY...
Issued at 307 PM CDT Wed Sep 5 2018

Minor to major flooding is occurring or forecast to occur along
several rivers across the forecast area. Rivers are expected to
crest over the next couple of days. See the latest river flood
statements for the latest forecast information.
