Area Forecast Discussion
National Weather Service La Crosse WI
652 PM CDT Mon Jul 1 2019

.SHORT TERM...(This evening through Tuesday)
Issued at 221 PM CDT Mon Jul 1 2019

At 2 PM, temperatures ranged from the mid 70s to mid 80s under
mostly cloudy skies.  100 mb mixed layer CAPES were in the 1000 to
2000 J/kg range across southeast Minnesota, northeast Iowa, and
southwest Wisconsin.  The RAP along with other CAMs are in agreement
that these CAPES will climb into the 2,000 to 3,000 J/kg range later
this afternoon and remain in the range through the early evening.
This instability will be growing ahead of a MCV moving east out of
southwest Minnesota. There will be sufficient support during the mid
to late afternoon for supercell thunderstorms and then as a 700 mb
speed moves east of the area.  This convection will transition to
training and multi linear storm mode.  Severe weather will be
possible from 4 PM to 10 PM. The main threat will damaging winds and
very heavy rain.  In addition, there will be the potential for large
hail and isolated tornadoes, but these threats would be mainly early
in the event.

For tonight, the 850 mb moisture transport will increase along and
near the Interstate 90 and 94 corridors.  With precipitable water
values between 2 and 2.25 inches and warm cloud depths of 4 to 4.5
km, these showers and storms will be highly efficient rain
producers. Rainfall rates could be in the excess of 2 inches per
hour. With soils already saturated, runoff will quickly run off
into area rivers and streams causing rapid rises and potential
flooding. In addition, there could be flash flooding in urban
areas and other flood prone areas. In bluff country, there will be
the possibility of mud and rock slides. Due to this, a Flash
Flood Watch has been issued.

On Tuesday, the front will be located across northeast Iowa and
southwest Wisconsin.  With ML CAPES of 2,000 to 3,000 J/kg and weak
convergence along the front, there will be a redevelopment of
showers and storms.  With weak shear, any severe weather will be
isolated and short-lived, so the marginal SPC risk looks good.

.LONG TERM...(Tuesday night through Monday)
Issued at 221 PM CDT Mon Jul 1 2019

It looks like the broken record forecast will continue through at
least the end of the work week. The 01.12Z models continue to show
the general zonal flow remaining in place across the Upper Midwest
with several short wave troughs coming out the western conus
troughing. The next of these waves looks to be timed up to come
across Wednesday afternoon and evening. With little overall change
expected to occur before this wave arrives, there should be ample
ML CAPE of 2000-3000 J/Kg in place ahead of it. The shear
available with this wave looks to be rather limited, as would be
expected in a zonal pattern, with maybe 25 to 30 knots in the 0-3
km layer. This would suggest at least some potential for some
strong to possibly severe storms again. However, the bigger
concern will continue to be with heavy rain and possible
flooding/flash flooding. The low level moisture transport should
increase Wednesday afternoon ahead of the approaching short wave
trough and looks to be focused right into the area. Precipitable
water values will still be on the order of 2 inches or higher with
warm cloud depths of 3.5 to 4.5 km. With this setup, there will
likely be the need for additional flash flood watches.

The zonal pattern looks to hold tight after the passage of the
Wednesday system with pretty good consensus that yet another short
wave trough could move over the area Thursday. Some differences
then between the models whether the next wave would come in Friday
or Friday night into Saturday. The surface boundary still looks to
be hanging out across the region and will likely serve as the
focus for additional convection as these waves move across the
region.

After these waves go by the area, there may finally be a pattern
change. The upper level ridge looks to build back north and over
the Upper Midwest for the last part of the weekend into the start
of next week. This may allow a cold front to push across the
region and bring in some cooler and drier air.

.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 650 PM CDT Mon Jul 1 2019

Scattered slow-moving thunderstorms with localized heavy rainfall
will continue to affect the TAF sites over the next few hours. The
thunder threat is gradually migrating from RST over towards LSE,
as RST is about to see a period of mainly showers. Gusty erratic
winds will be possible over the next couple hours, but the
potential for severe winds is diminishing. Otherwise tempo IFR
conditions expected with the heavier downpours. Will see
continued potential for scattered showers overnight and perhaps
isolated thunderstorms, with rain chances exiting the area around
or shortly after daybreak. Wouldn't rule out some shallow BR
overnight given the abundant low level moisture, but winds will
stay breezy just above ground level and should limit this
potential. MVFR cigs will be a concern from around daybreak
through Tuesday morning, until daytime mixing raises cigs and
scatters out the deck towards midday.
