updated aviation portion for 06z TAF issuance

Short term Tonight and Saturday
issued at 245 pm cdt Fri aug 18 2017
a short-wave trof will brush past the southern part of the
forecast area late this afternoon and evening, and bring
scattered light sprinkles to areas south of a line from
mfi-mtw. Clearing should occur later tonight as the upper trof
exits the region and weak high pressure arrives. This should
allow temperatures to drop into the 50s and lower 60s, and
lead to patchy fog development over much of north central
and central wi. The fog will be most prevalent in the favored
locations in north central wi.

On Saturday, a weak convergence zone will set up in the central
u.P. And far northeast wi, where CAPE is also forecast to increase
to around 1000 j kg. Have added slight chance chance pops in the
far northeast, especially over door county. Otherwise, it will be
a pleasant summer day, with partly cloudy skies, warm temperatures
and comfortable humidity levels.

Long term Saturday night through Friday
issued at 245 pm cdt Fri aug 18 2017
zonal flow at 500mb will continue into early next week, then a
500mb ridge is expected to amplify across the rockies with
northwest flow and depending trough across the great lakes region
during the middle to end of next week. Warmer than normal
temperatures are expected at the beginning of the period, then
should trend to or below normal for the latter half of next week.

Quiet conditions will continue Saturday night as high pressure
slides east of the area. Did make minor adjustments to low
temperatures to account for our typical cold spots. On Sunday,
a weak cold front will approach from the west. This system will
bring a chance of showers and thunderstorms to portions of north-
central and far northeast wisconsin Sunday afternoon. The front is
expected to sink slowly southward across the area Sunday night,
bringing a chance of showers and thunderstorms to the entire
region. The system is expected to stall on Monday as the next
area of low pressure moves along the front and approaches
wisconsin from the west. At this time, it appears that cloud
cover and the possibility of rain will spoil the solar eclipse
across the area.

Showers and thunderstorms are expected Monday night into Tuesday
morning as low pressure moves along the front. The rain should end
across eastern wisconsin Tuesday afternoon as high pressure builds
into the region. Cool and dry conditions expected Tuesday night.

Latest model guidance is suggesting instability showers are
expected to develop across far northeast wisconsin late Wednesday
morning into Wednesday afternoon. Have increase rain chances in
this area. Any showers should end around sunset. Otherwise, dry
and cool conditions expected Thursday and Friday.

Aviation For 06z TAF issuance
issued at 1035 pm cdt Fri aug 18 2017
clearing will continue overnight, which should allow some fog to
develop, especially in the favored locations of north central wi.

The fog should mix out by 14z sat. Aside from the fog,VFR
conditions will prevail over the TAF sites through the period.

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.
