updated aviation portion for 00z TAF issuance

Short term Tonight and Wednesday
issued at 228 pm cst Tue jan 23 2018
challenge in the short term forecast will be cloud coverage and
the impact on temperatures tonight.

Low clouds have held tight across the area today, and expansive
clearing noted across eastern minnesota and far western wisconsin
showed little sign of eastward progression. This is also evident
on time sections which show persistent low level moisture over the
next day. As a result, have increased cloud cover some from the
previous forecast.

Also of note, satellite imagery showed some breaks in the clouds
starting to form across central wisconsin early this afternoon.

Guidance would also suggest that some holes may develop in the
cloud deck late this afternoon through early tonight, and then
fill back in by Wednesday morning. Have accounted for this trend
in the sky forecast.

Due the uncertainly of any clear periods tonight, confidence in
min temps is low. Raised temperatures a few degrees from previous
forecast as skies are not expected to be clear for very long.

However, even a few breaks combined with light winds will allow
temperatures to fall rapidly. Current forecast is for lows in the
single digits across north- central and central wisconsin, and in
the lower teens across the fox valley and lakeshore. These will
likely need adjusting if clouds do not pan out as expected.

Surface high pressure passes across southern ontario Wednesday,
but has little influence on the low level moisture across
wisconsin. Otherwise, fairly quiet weather and light winds are
expected tomorrow with high temps near normal, in the lower to
middle 20s.

Long term Wednesday night through Tuesday
issued at 228 pm cst Tue jan 23 2018
upper ridging will occur over the latter half of the work week,
with dry weather anticipated through the period. A warm front is
expected to lift through the region Thursday night into Friday,
leading to a big warmup. Expect high temperatures in the lower to
middle 40s over most of the area on Friday, but a few locations
may reach 50 degrees from waupaca and wautoma eastward into the
fox valley, where little or no snow cover exists.

Weak cold frontal passages and associated upper troughs are
expected to move through the region Friday night, and Saturday
night Sunday. Moisture will be sparse, so neither system is
expected to produce much precipitation. For now, will just carry
small pops in far north central wi for minor lake-effect
potential as winds turn northwest behind the fronts.

High pressure will move across the region Monday and Monday
night, followed by southerly return flow and WAA next Tuesday.

Small precipitation chances may be needed across northern wi
on Tuesday, but that is a low confidence day 7 forecast.

Aviation For 00z TAF issuance
issued at 541 pm cst Tue jan 23 2018
a few holes in the widespread MVFR clouds opened up over parts of
east central wisconsin late this afternoon with moreVFR level
cigs noted over far northeast wisconsin. With a diminishing
northwest flow, anticipate little change in sky condition tonight
into Wednesday. More MVFR clouds noted over iowa and southern
minnesota may work back into the area later Wednesday as the flow
turns more southwest.

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.
