updated aviation portion for 06z TAF issuance

Short term Tonight and Thursday
issued at 209 pm cdt Wed aug 23 2017
the latest rap analysis and satellite radar imagery show northwest
flow continues off lake superior early this afternoon, with moisture
fluxes leading to a broken CU field over the northern part of the
state. Still seeing sporadic obs of light drizzle being reported
over vilas county. The next shortwave is moving southeast over
southern manitoba where scattered light rain showers are occurring.

The mid-level cloud deck associated with this system is already
approaching northeast minnesota. Precip chances with this system,
and impact on temps are the main forecast concerns.

Tonight... Shortwave trough over southern manitoba will swing across
the region late tonight. Mid and high clouds will be on the
increase during the evening hours. But low levels will struggle to
saturate due to the very dry airmass as evident by the 12z grb
sounding. As a result, precip chances look to be confined to mainly
central wisconsin between 08-12z approximately, and will increase
precip chances some there. The influx of clouds will likely hold up
temps for a period over north-central wi before they fall again late
as skies begin to clear. Though patchy frost remains possible in
the cold spots, concerns about cloud cover are high enough not to
issue a frost advisory. Will instead issue an sps in case the
clouds diminish before reaching northern wi. Lows ranging from the
mid 30s in the cold spots to near 50 degrees over the southern fox
valley.

Thursday... As the shortwave departs, clouds will be exiting central
and northeast wisconsin during the morning hours. High pressure
will then reassert itself for the rest of the day, with a drier
airmass than the one currently present over the area. As a result,
should see less cloud cover during the afternoon hours. Highs
ranging from the mid 60s to near 70.

Long term Thursday night through Wednesday
issued at 209 pm cdt Wed aug 23 2017
cool high pressure will continue to dominate the region Thursday
night into Friday. Clear skies and light winds provide the
potential of patchy fog Thursday night. Thursday night overnight
lows across northern wisconsin may also support pockets of frost
over the climatological cool spots.

Progs are trending for a wetter weekend for part of the area.

While a surface high pressure system remains anchored over the
great lakes region, return flow over the northern plains will
spread over parts of the western great lakes region. Progs then
drift an 850 mb low with surface low across the state Saturday
night into Sunday. The more aggressive GFS model run provides up
to a quarter inch of rain over much of the area Saturday night and
Sunday while the ECMWF is a bit slower with the arrival Saturday
night.

The low pressure region then gradually shifts south Sunday into
Monday but still near the area for continued rain chances. High
pressure then attempts to build back into the area as upper
heights increase. Precipitation chances then become more isolated
or end and temperatures return to more normal levels.

Aviation For 06z TAF issuance
issued at 1046 pm cdt Wed aug 23 2017
an upper level disturbance will bring a chance of light showers
to mainly central wi late tonight, along with bkn to ovc mid-level
clouds to the rest of the region. However, conditions should
remainVFR with this system. Skies will clear early Thursday
morning across most of the area and remain mostly sunny andVFR
through the afternoon with light winds.

Grb watches warnings advisories
None.

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.
