updated aviation portion for 06z TAF issuance

Short term Tonight and Sunday
issued at 227 pm cdt Sat aug 17 2019
partly cloudy skies were noted across the region this afternoon
with temperatures in the middle 70s to lower 80s.

For tonight, the fair weather cumulus clouds will dissipate
around sunset. The low level jet is expected to crank up
this evening, bringing an increase in mid and high clouds
to the region. Models indicating a complex of thunderstorms
moving across iowa, southern wisconsin and northern illinois
overnight. Elevated convection should arrive across the area
after midnight, closer to around sunrise across northeast
wisconsin. Have chances of rain increasing rapidly after
midnight and continue into Sunday morning. The first round
of showers and thunderstorms will exit the area Sunday morning.

Things do get a little more interesting Sunday afternoon as a
cold front moves across the region. If we could break out tomorrow
afternoon from the low clouds, bufkit soundings indicated one to
two thousand j kg of cape, 0-6 km shear values around 30 knots,
and total totals around 50. Do expect the clouds to remain across
the area though much of the day, but still could not rule out an
isolated severe thunderstorm if we break out tomorrow afternoon
with damaging winds or large hail. Any storms later tonight and
Sunday could produce locally heavy rainfall and localized
flooding.

Did not stray far from the previous forecast for minimum
temperatures tonight. Leaned toward the warmer met guidance
for highs on Sunday.

Long term Sunday night through Saturday
issued at 227 pm cdt Sat aug 17 2019
a relatively progressive upper level pattern over north america
will start the work week, but transition to amplified ridging
over the western u.S. By Wednesday. This ridging will generate a
northwest flow across the northern midwest and pull cooler
canadian air into northeast wisconsin for at least a couple of
days. A surface-based cold front will move through the region
later on Tuesday and produce some shower and thunderstorm
activity. Then cool, dry air will move in and dominate for a
couple of days before the upper level flow flattens out again and
temperatures moderate.

Aviation For 06z TAF issuance
issued at 1042 pm cdt Sat aug 17 2019
vfr conditions are expected through the early morning hours,
except near the lake michigan shore where there may be some low
clouds or fog. A warm front approaching from the southwest will
bring showers and thunderstorms along with ifr conditions late
tonight through midday Sunday. Ceilings and visibilities will rise
Sunday afternoon and evening as a cold front moves through the
area.

Grb watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
