What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS La Crosse, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 7, 2:49 AM CDT, 1 hour 22 minutes earlier.

Area forecast discussion, Jul 7, 2:49 AM CDT, 1 hour 22 minutes before

Area Forecast Discussion
National Weather Service La Crosse WI
249 AM CDT THU JUL 7 2016

.SHORT TERM...(Today through Tonight)
Issued at 249 PM CDT THU Jul 7 2016

Surface analysis at 2 am had a warm front draped west-east from
northern IA into far south WI. Rich theta-e air advecting northeast
out of the Plains into/over the warm front, combined with a weak mid-
level trough was producing a fairly strong QLCS across southern MN
into central/western IA. This line was racing east around 40 mph and
should be into southeast MN/northeast Ia by 3 am, then gradually
weakening as it crosses east of the Mississippi River after 4 am.

Will see that QLCS mostly pushed east out of the area by mid-
morning, leaving a brief quiet period from late morning into the
early afternoon. Increasing moisture transport into the area ahead
of low pressure pushing out of the Plains expected to produce
scattered shower/thunderstorm through the afternoon. Expect these
storms to gradually ramp up going into late afternoon/early evening
as cold front pushes from MN/IA. Plenty of CAPE will work with 0-3km
bulk shear of 25-35kt for strong to severe storm potential...
damaging wind being the main threat. Current thinking is there will
be a fairly solid line of incoming storms with the front but there
may be a northern mechanically/pva forced component and a
southern/more thermodynamically-driven component as the front rolls
in. In theory then, it is quite possible that the line of storms may
split north south of I-90 during the early evening. Have left mostly
likely pops in for the entire area for now/highest north with the
pva, but wanted to convey the possibility of the split. Expecting
the cold front/bulk of storms to lift northeast of I-94 after
midnight.

.LONG TERM...(Friday through Wednesday)
Issued at 249 PM CDT THU Jul 7 2016

Friday will see a continued chance of showers and storms mainly
northeast of I-94 along with fairly breezy northwest winds in
cyclonic flow behind low pressure over the Upper Peninsula. Cooler
and drier otherwise with highs in the 70s.

High pressure builds in for the weekend for a dry/cooler spell.

Shower/thunder chances returns Monday through Wednesday as low
pressure tracking across the Northern Plain into southern Canada
pushes a cold front toward/through the region.

&&

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1100 PM CDT Wed Jul 6 2016

Still some uncertainty with how the area of thunderstorms moving
east/southeast out of the northern plains will evolve-track
overnight. Latest NAM joins the EC with taking the activity more
southeast - away from the taf sites. Mesomodels though still favor
bringing some shra/ts across krst/klse in the 09-12z (or so) time
frame. HRRRs doing the best with current convection and will lean
toward that solution for now. Will stay optimistic with cigs,
keeping it predominately VFR.

Somewhat variable clouds tomorrow with winds likely from an easterly
direction Thu. Another round of shra/ts for the region Thu evening,
but some hints that most of the activity could move north and south
of the taf sites. Confidence not high on how this will evolve...with
any lingering morning convection playing an important role. Will add
vcts for the moment, but expect some refinement to this
forecast through the day Thu.
