Short term (this evening through Tuesday)
issued at 255 pm cdt Mon may 22 2017
main impactful weather concerns are on thunderstorms this evening
with the potential for some small to perhaps isolated large hail and
gusty winds.

Currently watching a shortwave moving through south dakota, headed
for the local area. Surface based CAPE values are expected to top
out in the 700 to 1000 j/kg range late this afternoon. Showers
and thunderstorms should initiate around 4 pm over portions of
south central minnesota into north central iowa. These storms will
then track east into southeast minnesota and northeast iowa by
late this afternoon into this evening. 0-6 km bulk shear values
are expected to range from 25 to 35 kts. So storms may become
organized briefly with the potential to produce large hail and
gusty winds. Freezing levels are also fairly low (right around
7kft), so hail production should be fairly efficient in any
stronger updrafts. We may see some hail up to the size of quarters
or possibly a little larger. Showers and thunderstorms will then
work east across the area through the evening hours. The main
areas impacted by these showers and storms will be locations south
of the interstate 94 corridor across southeast minnesota,
northeast iowa, and southwest wisconsin.

Low pressure then spins over the region on Tuesday with continued
chances for showers and perhaps a few thunderstorms.

Long term (Tuesday night through Monday)
issued at 255 pm cdt Mon may 22 2017
the low will exit the area late on Wednesday but lingering cyclonic
flow aloft may bring isolated to scattered showers to the region.

The low finally exits the area late Wednesday into Thursday with dry
weather expected. High temperatures will trend upward slightly
Thursday into Friday as another trough approaches from the west. The
trough then pushes a weak front through the region on Friday and we
may see some showers and possibly a few thunderstorms with this
feature. Small chances for showers and possibly thunderstorms
continue through the weekend into early next week as a long wave
trough moves across the upper mississippi river valley. So, if you
have outdoor plans for this memorial day weekend keep a close eye
on the weather. The pattern favors slightly cooler temperatures
and chances for rain showers and a few thunderstorms.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 1120 pm cdt Mon may 22 2017
cigs: looking atVFR CIGS overnight-tue morning as upper level
trough/low drops south/southeast through the region. Models
suggesting that the clouds will continue to lower tue
afternoon/evening - with the potential for ifr/MVFR. However, some
of that is tied to an expanding stratus layer northwest of the
system's sfc low/coupled with the upper level low. Not confident in
this scenario. Going to hold with MVFR/near MVFR CIGS for both
krst/klse from Tue afternoon through the period for now. Expect some
refinement in the forecast later in the day as trends become more
clear.

Wx/vsby: a few lingering showers through about 08z or so, then the
threat for more showers returns by late morning/early afternoon -
especially for krst (cold air advection/perky low level lapse rates
and the upper level low). Going -shra for krst for now, with vcsh at
klse. Expect a decrease in coverage by 00z wed.

Winds: mostly a north direction overnight - holding there through
tue night.

Hydrology
Issued at 255 pm cdt Mon may 22 2017
minor flooding is expected along portions of the mississippi
river this week. Minor flooding continues on the yellow river at
necedah and the trempealeau river at dodge. Monitor river levels
closely if you have interests along these rivers.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
