updated aviation portion for 00z TAF issuance

Short term Tonight and Tuesday
issued at 334 pm cst Mon jan 22 2018
forecast concerns revolve around ongoing headlines and
precipitation types and amounts this evening and overnight.

Forecast was nearly on track as far as precipitation types today
and warning advisory headlines will continue as planned. Current
(3pm) radar and surface obs showed moderate to heavy snow across
far northern wisconsin pushing north. There is another band of
heavier precipitation just getting to the southern forecast area
and is on track to move through during the late afternoon and
early evening, which will impact the evening commute. Boundary
layer temperature are a concern as this band moves through the
fox valley and lake shore counties. Many surface temperatures are
within a degree or two of freezing. Time sections show enough
saturation and lift over the next couple hours to get a quick
accumulation of slushy snow, but will depend on whether those
flakes melt before reaching the ground or not. Sps was issued to
highlight this concern. Further north (in the warning and advisory
counties) all snow is expected this afternoon and early evening.

The dry slot evident on current satellite imagery will start
advecting into the area later this evening. This will clear out
some of the mid-level moisture and limit the potential for snow,
with any precipitation expected to transition over to freezing
drizzle for all but the far north. By this point there will not be
as much lift present, so expect any freezing drizzle to be light
and ice accumulations to be minimal. However, expect roads to
still be slippery in spots especially on bridges and untreated
roads.

Models in agreement that the precipitation comes to an end around
12z in central wisconsin and gradually pushes east of the entire
area by 18z. Some cooler air filtering in behind the system may
briefly transition precip back to snow before departing. Dry
weather expected for Tuesday afternoon.

Temperatures will remain fairly steady through late this
afternoon then gradually fall overnight. Lows will be in the 20s.

Strong CAA will prevent temperatures from rising much on Tuesday,
perhaps only a couple degrees at many locations.

Long term Tuesday night through Monday
issued at 334 pm cst Mon jan 22 2018
fairly quiet weather is anticipated through the period, with only
small precipitation chances associated with weak cold frontal
passages Friday night, and Saturday night into Sunday.

Temperatures will start off near normal for the beginning of the
period, warm to much above normal Friday into Saturday, then
drop back to near normal by early next week.

Aviation For 00z TAF issuance
issued at 600 pm cst Mon jan 22 2018
ifr lifr conditions to continue tonight. Moderate to heavy snow
will persist into early evening over central wisconsin and most of
the night over the north. A band of mixed precipitation is
drifting northward over east central wisconsin this evening. Llws
conditions will linger over northcentral and central areas this
evening.

Expect conditions to begin to improve to MVFR levels late tonight
and especially Tuesday morning and then intoVFR areas for
Tuesday.

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.
