updated aviation portion for 12z TAF issuance

Short term Today... Tonight... And Sunday
issued at 336 am cdt Sat apr 20 2019
high pressure at the surface and aloft will make for
a sunny and mild day with light winds and low relative humidity.

Highs will be around ten degrees above normal except near the lake.

Middle clouds will arrive late tonight as warm advection
increases aloft. The clouds will keep temperatures 5 to 10 degrees
above normal.

Easter Sunday should start out dry in most places, but there will
be an increasing chance of showers in the north as a cold front
approaches slowly from the north. Highs will be well above normal.

Long term Sunday night through Friday
issued at 336 am cdt Sat apr 20 2019
models continue to trend with more rainfall for the system
Sunday night into Tuesday morning. Still difficult to pinpoint
where the heaviest rain would occur, but current forecast now
has the highest totals across north-central wisconsin. The
additional rainfall could lead to new additional river flooding.

For Sunday night into Monday, trying to figure where the front
will set up is difficult as the ECMWF canadian models were
further north compared to the GFS nam. Thinking the front will
sag further south, due to the fact the great lakes waters are
still cold and this air mass density difference will help push
the front southward down the bay and lake. There is a chance of
thunderstorms Sunday night, but these storms are not expected to
be severe.

For Monday, high temperatures may be in the 40s to around 50
with the further south frontal position of the GFS nam, while the
ecmwf canadian model would keep a mild southerly wind with highs
in the upper 50s to middle 60s. There is a chance of thunderstorms
Monday afternoon and evening. These storms are not expected to be
severe. For Monday night, the surface low is expected to move
across the western great lakes region, bringing additional
rainfall to the region. The low pressure system will continue to
move away from the area on Tuesday, bringing an end to the rain
Tuesday morning. High pressure is expected to bring dry conditions
on Wednesday. The next chance of showers will be late Wednesday
night and Thursday with the next cold front moving across the
northern united states. High pressure builds into the region
Thursday night then east of the region Friday afternoon, bringing
dry conditions to the region. Only minor changes to MAX min temp
grids during the period.

Aviation For 12z TAF issuance
issued at 651 am cdt Sat apr 20 2019
it is a great day for flying today with clear skies
and light surface winds.VFR will continue tonight with some mid
clouds arriving late. Easter Sunday will have showers arriving in
northern wisconsin though it should stay dry further south.

Fire weather
Issued at 336 am cdt Sat apr 20 2019
relative humidities will drop to near critical values this
afternoon. Temps will be about ten degrees above normal, but
winds will be light.

Hydrology
Issued at 336 am cdt Sat apr 20 2019
minor to moderate flooding continues on several rises across
the area. Look for the the wisconsin river basin to slowly fall
through the weekend. Levels on the wolf and menominee will be
steady or slowly rise through the weekend and into next week.

It appears the system will bring more rainfall to the region
from Sunday afternoon into Tuesday morning. Initial thoughts that
a half inch to one inch of rain can be expected across much of
the region, with locally higher amounts possible. Additional new
flood concerns could arise, especially if we get totals approaching
an inch or greater.

Grb watches warnings advisories
None.

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.
