Area Forecast Discussion
National Weather Service La Crosse WI
226 PM CDT Tue May 29 2018

.SHORT TERM...(Tonight thru Wednesday night)
Issued at 226 PM CDT Tue May 29 2018

The main short-term fcst concerns are SHRA/TSRA chances much of the
period and cooler temps Wed.

Data analysis at 18z had a weak ridge of high pressure over the
Upper Midwest with low pressure in the northern plains and the
Alberto low over northern AL. Quiet across much of the region thru
early afternoon. Bulk of SHRA/TSRA up to 18z limited to western MN
with some weak sfc convergence and piece of shortwave energy
rotating around the mid level low over the Black Hills. A few
SHRA/TSRA began developing just before 18z with diurnal warming
and weak convergence over SE MN and nearby areas. Otherwise,
another hot late May day in progress across the region with most
early afternoon temps again in the mid 80s to lower 90s, some
15-20 degrees above normal.

Model runs of 29.12z initialized quite well, for the most part.
Most continue to struggle with sfc dew points across much of
MN/IA/WI, especially GFS. Solutions similar thru tonight as remnants
of Alberto lift northward and troughing comes east across the
central/northern plains. Good consensus for at least partial phasing
of these 2 troughs Wed, but generally east of the fcst area. Lead
energy/Alberto remnants to sweep east of the region Wed night while
some secondary northern stream energy drops into MN. Overall short-
term fcst confidence is good this cycle.

For the short term, eyes are watching a shortwave/piece of energy
models lift out of the Alberto trough and northward across the area
this evening. Some reflection of this wave seen in WV imagery over
NE MO/west-central IL, but does not appear as robust as 12z
NAM/GFS/GEM would have it. Even with the more robust wave in the
models, models reluctant to generate convection in the south end of
the fcst area late this afternoon/evening, other than that
associated with models being too high with sfc dew points this
afternoon/evening. Will leave any SHRA/TSRA chances for late this
afternoon/evening on the lower side across the south/west sides of
the fcst area. Deeper moisture/higher PW airmass lifting north with
Alberto remnants (PWs of 1.5 to 2 inches) arrives for later tonight/
Wed, ahead of the northern plains trough to move across the region
Wed. Rain chances increasing later tonight, peaking in the 60-80+%
range around mid-day Wed look good. Rain chances to then diminish
Wed night with passage of the lead mid level trough axis. MUCAPE
progged over the area later tonight/Wed but how much is rather
questionable.  Model consensus in the 500-1K j/kg, perhaps up to
1500 j/kg, range, but highly variable. Considerable cloud cover Wed
and convection already in the morning looking to keep CAPE limited.
These factors to also impact high temps Wed. Will stay with a model
blend/consensus of highs in the mid 70s-lower 80s, but if clouds/
SHRA/TSRA prevail, Wed highs in the grids could well be 10F too
warm. With lesser CAPE Wed and deep layered shear progged to
generally be less than 25kts, severe TSRA are not anticipated later
tonight into Wed evening.

.LONG TERM...(Thursday through Tuesday)
Issued at 226 PM CDT Tue May 29 2018

For Thursday thru Friday night: main fcst concern this period are
SHRA/TSRA chances Thu afternoon/evening and again later Fri night.

29.12z model runs in decent agreement for the secondary trough axis
and shortwave to rotate across the region Thu, to be followed by
rising hgts/shortwave ridging Thu night into Fri night. Some timing
differences with the next shortwave thru westerly flow and into the
region by Fri night, GEM faster, GFS/ECMWF slower. Fcst confidence
good Thu-Fri then average Fri night.

Shortwave and mid level trough axis pivots across the area Thu with
some cooler temps aloft and deeper cyclonic convergence. GFS the
most robust with this. PW values progged as high as 1.5 inches with
MUCAPE in the 500-1500 j/kg range. 20-50% SHRA/TSRA chances centered
on Thu afternoon and highest across the NE half of the fcst area
looking good. Precip chances exit rather quickly Thu evening with
passage of the sfc-mid level trough axis, with drier high pressure
building in for later Thu evening thru Fri evening. Slower GFS/ECMWF
would keep Fri night dry, while faster GEM quickly brings the next
sfc-mid level trough/front and round of lift into the area by later
Fri night. With some trend of models toward faster of earlier
solutions tonight into Thursday, cannot rule out faster GEM being
more correct by Fri night. The consensus 20-30% SHRA chances across
much of SE MN/NE IA later Fri night OK for now. Blend of cooler
guidance highs (but still above to well above normal) for Thu/Fri
appear well trended.

For Saturday thru Tuesday (days 4 to 7): main fcst concerns this
period are SHRA/TSRA chances Sat and again Tue.

Medium range model runs of 29.00z/29.12z in reasonable agreement for
the northern stream shortwave to be rather progressive across the
region Sat, favoring faster of earlier runs. Improving consensus for
quiet looking zonal flow across the north-central CONUS Sunday, then
plenty of detail differences with timing/strength of potential
shortwaves thru the flow early next week. Fcst confidence average
Sun/Mon then below average Mon/Tue.

Shortwave trough to push a sfc trough/cold front across the region
Sat. Some timing differences as expected, but all models producing
at least a bkn line of convection as the front would move across.
Models do not bring along much for CAPE, with perhaps 250-500 J/KG
MUCAPE near/west of the MS river Sat afternoon/early evening.
Consensus SHRA/TSRA chances in the 30-50% range Sat good for now and
limited TSRA mention to Sat afternoon/evening hours. With a cooler
airmass over the region and potential for more clouds and the SHRA,
Sat may well be the coolest day thru early next week. Drier high
pressure builds in from the northern plains for Sun into Mon.
Potential for some SHRA/TSRA chances on Tue but until the day 7
short-wave detail differences sort themselves out will leave Tue dry
per the consensus. Blend of guidance temps some 5F to 10F above
normal Sun-Tue looking well trended for now.

MVFR cloud cover expected to creep in from time to time Wednesday
morning.
