...High Water Downstream Of Friendship Lake...

.Early this afternoon, the Adams County Sheriffs Department
reported there was no significant change in conditions in
Friendship. High volumes of water were still being released from
the Friendship dam after recent heavy rains caused water levels to
rise on Friendship Lake. This release of water could result in 
high water levels along the Little Roche A Cri Creek from the dam 
downstream to Castle Rock Lake. According to the Adams County 
Sheriffs Department, the dam in Friendship has not failed.

The Flash Flood Watch continues for

* A portion of central Wisconsin, including the following area,
  Adams. This watch is for the Little Roche A  Cri Creek from the
  Friendship dam downstream to Castle Rock Lake.

* Until 10 PM CDT this evening

* Recent heavy rains across Adams County caused the water levels 
  on Friendship Lake to become high. This has resulted in high 
  volumes of water to be released through the Friendship dam 
  into the Little Roche A Cri Creek. 

* High water levels will be possible along Little Roche A Cri 
  Creek downstream to Castle Rock Lake. Immediate impacts will 
  be to Friendship Park.

.SHORT TERM...(Today through Monday)
Issued at 235 AM CDT Sat Jul 8 2017

Another nice day for the region today, albeit without the threat for
showers/storms. High pressure will be the main weather influence,
sinking southeast across the region today/tonight.

Showers and storms return for Sunday into Monday as all the models
drop a few bits of upper level energy over a ridge that extends into
southern Canada, spinning them across the Upper Mississippi River
Valley. All suggest that showers/storms will streak southeast across
northern parts of mn/wi during the morning/early afternoon. Focus
then turns more south for later afternoon/night into a building pool
of instability and an increasing low level jet. Another piece of
upper level energy also likely to play a role in storm development
here. Higher CAPES to work with for the Sunday night convection,
with +2000 K/jg of MUCAPE. In addition, shear would provide some
support for storm development - around 40kts 0-6km and 30kts 0-3km.
So as it looks right now, the I-94 corridor northward will have the
higher chances for showers/storms Sunday, with that shifting mostly
west of the Mississippi for Sunday night. Instability and shear would
support a few strong storms, and potentially some severe. The night
time storms would have a heavy rain threat, in addition to a
hail/wind potential.

An associated surface front holds up west to east south of the area
on Monday, and models want to swing a few more ripples in the upper
level flow that could/would work on the boundary. Most of the models
want to push the front far enough south that the threat for
additional showers/storms on Monday would also be south. That said,
no guarantee that the upper level energy will keep that far south.
Going to hold some small chances in the east.

.LONG TERM...(Tuesday through Friday)
Issued at 235 AM CDT Sat Jul 8 2017

Fairly unsettled weather pattern for much of the new week with
variations of zonal flow, to shortwave ridging, to potentially
troughing by next weekend. The GFS and EC push various bits of upper
level energy across the region, resulting in periodic rain/storm
chances. Not a lot of agreement on the details of
location/strength/timing, keeping forecast confidence in check. One
area they have some consensus on is with an upper level shortwave
tracking across northern parts of the region Tue night/wed. This
system could lift a lingering west-east running sfc boundary to the
south, northward as a warm front. Decent shot for widespread
showers/storms in this rendition, favoring northern halves of mn/wi.

Summer warmth and humidity quickly return for next week. Dew points
progged from the low 60s to low 70s with highs solidly in the 80s
for most. Air conditioners probably going to get a pretty good run
this next week, if for nothing else the expected humid conditions.

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 606 AM CDT Sat Jul 8 2017

Seasonably cool and dry Can high pressure will continue to provide
good VFR conditions today thru Sunday morning. The center of the
high will be nearby thru Sun morning, for winds less than 10kts thru
the taf period. With plenty of July sunshine and diurnal warming
today, few to sct cumulus in the 5k-6k ft range expected this
afternoon into early this evening.
