Short term (tonight through Tuesday)
issued at 150 pm cdt Mon aug 19 2019
upper level shortwave trough slides east across the northern plains
this evening with the low level jet 850 mb moisture transport nosing
into the shortwave by 09z as it shifts across northern ia.

Convection should take off in earnest as this occurs, and meso
models show just that with rapid development between 06-09z over
northwest ia, dropping southeast into western il toward 12z. Despite
overnight timing, there looks to be some elevated instability to
work on along with favorable shear, moreso in the 0-3 km layer.

Expect some strong to severe storms across ia overnight. Current
location would keep the bulk of this threat just southwest of the
local forecast area. Certainly a scenario that bears a close watch,
especially for northeast ia.

As the MCS exits southeast, some models (esp rap) hang an inverted
trough piece of upper level energy northwest of mcv. In those
scenarios, enough low level saturation also hangs back, providing
ingredients for cont shower isold storm chances across the south
into the afternoon. Don't anticipate any strong severe threat with
any of this activity. Will hold small pops for now.

Another bit of upper level energy looks to slip east southeast
across northern mn Tue morning, into northern wi by the evening.

Differences in timing between the variety of models... With latest
hrrr about 12 hours quicker on bringing in convection north of i-94
compared to the 12z nam12. That said, many of the other models only
produce a smattering of showers storms. Going against the convection
is no little tap to gulf moisture (focused south with that exiting
mcs), cloud cover across the south from the MCS (how extensive,
thick), and bufkit soundings suggest capping that could will need to
be overcome (either warming or by the front shortwave). What does
get going will have some instability to work with - rap suggests
upwards of 2500 j kg of SBCAPE over northern wi by 00z Wed and
potentially +30 kts of effective shear. If that manifests, enough
support for some stronger isold severe storms. A lot of "ifs" though
for Tue afternoon evening... And confidence is not high at this time
with how it will playout.

Long term (Wednesday through Monday)
issued at 150 pm cdt Mon aug 19 2019
models in good agreement with the overall, big picture for the last
half of the week.

Upper level shortwave trough slated to drop southeast across the
great lakes Wed wed night. Little saturation to work on though -
most of that will be cleared south southeast with the Tue system. A
sfc high then progged to build in from the west for Thu Fri while
the axis of an shortwave ridge a loft treks east across the northern
plains. Should see a dry end to the work week, with temps likely a
few degrees below the late aug normals.

The ridge quickly shifts east for the weekend, allowing for a
shortwave trough to nudge in from the west. Showers storm chances
will accompany the trough and its associated sfc front. Should also
see a bump up in temps as winds turn more southerly.

Aviation (for the 06z tafs through 06z Tuesday night)
issued at 1043 pm cdt Mon aug 19 2019
patchy to areas of valley fog are possible at klse tonight then
MVFR stratus could impact the TAF sites from mid Tuesday morning
into Tuesday afternoon. Mid to high level clouds blowing off of
thunderstorms over northwest and central iowa will create
increasing clouds at the TAF sites tonight and should keep the
valley fog from going dense at klse. The storms then push
southeast of the region Monday morning and stratus could develop
along moist air pushing north into the area in the wake of the
morning storms. A cold front then approaches the region from the
northwest Tuesday afternoon and storms could develop along it and
impact the TAF sites, especially klse, late Tuesday afternoon into
Tuesday evening.

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.
