updated aviation portion for 06z TAF issuance

Short term Tonight and Monday
issued at 249 pm cdt Sun mar 24 2019
main forecast issue over the next 24 hours to center on
temperatures as canadian high pressure starts to exert its
presence over the region.

The 19z msas surface analysis showed the cold front had pushed
into southern wi this afternoon, sending winds to the north-
northeast and ushering in a cooler drier air mass into the area.

This front also shunted any potential northward movement of a
system moving across the midwest, thus any precipitation had been
relegated to far southern wi. Visible satellite imagery indicated
the back edge of clouds now over upper mi with a movement to the
south.

The system to our south tracks east into the ohio valley tonight,
while canadian high pressure begins to build southeast into the
great lakes. Any lingering cloud cover will disappear by mid-
evening as a very dry air mass settles over the region. Clear
skies, diminishing winds and a colder air mass will bring a cool
night to northeast wi with min temperatures from 5 to 10 above
zero north, upper teens to around 20 degrees east-central wi.

This high pressure to stretch from the upper ms valley through the
great lakes, toward the new england states on Monday. Anticipate
plenty of sunshine with light northeast winds becoming northwest.

Despite the cool start to the day, the dry air mass will allow
temperatures to quickly warm with readings in the upper 30s
north-central wi near lake mi, mainly lower 40s elsewhere.

Long term Monday night through Sunday
issued at 249 pm cdt Sun mar 24 2019
northwest upper flow should make for dry weather
through at least Tuesday night. A surface front could produce
some sprinkles or light showers Wednesday. The models now suggest
that the front will make it further south into central indiana and
central illinois Thursday and Friday.

A surface low is forecast to move northeast along the front and
produce precipitation across southern wisconsin and northern
illinois Friday and Saturday. The models have been trending further
south with the upper system as well, so it now looks like any
precipitation will be light and mostly across the far southern
part of the forecast area.

Aviation For 06z TAF issuance
issued at 1132 pm cdt Sun mar 24 2019
canadian high pressure will drop south into the region overnight,
and lingering stratocumulus over central and east central wi will
shift south of the forecast area. Gusty northeast winds will also
subside overnight.VFR flight conditions will prevail through the
taf period.

Hydrology
Issued at 249 pm cdt Sun mar 24 2019
a slow snowmelt is expected across the north for the rest of this
week. It now appears that any significant rain this Friday and
Saturday should stay south of our forecast area. Some streams and
rivers will remain high even without any extra rainfall, and ice
jams could create flooding should they occur.

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.
