315 pm cdt Sat mar 23 2019

Short term
Clouds will begin to increase overnight as a low pressure system
over the kansas nebraska border shifts east. Rain chances will
move into southwestern portions of our CWA after 3 am and shift
east. Activity will continue off and on throughout the day before
ending during the early evening. Activity will be mainly along and
south of i-94 with best chances along the wisconsin illinois
border.

The main forcing with this system is 500 mb vorticity advection
over the area. There is not much in the way of lift in the lower
levels or with the upper level jet. With that being said there are
a few uncertainties with how far north precipitation will get.

There is dry air in place which will delay the incoming moisture.

Another factor to consider is the front moving through late
Sunday afternoon into the early evening. This front will be
bringing in dry air and colder temperatures. This may result in a
light wintry mix before precipitation clears the area, or may end
precipitation sooner if it has more momentum than is currently
expected.

Long term
High pressure will build into the area for Monday and Tuesday,
with clear skies and cool temperatures expected. Highs Monday look
to be in the low 40s (upper 30s near the lake), with mid 40s
expected on Tuesday. Clear skies and light winds will allow
overnight lows to fall into the low 20s.

High pressure will push east into new england by Wednesday
morning, with gusty southerly flow developing across the area.

This will help boost temperatures into the low to mid 50s for
Wednesday.

Continued strong southerly flow and warm advection will help boost
temps to around 60 by Thursday. Showers and a few thunderstorms
will be on the increase from late Wednesday night through the day
on Thursday.

Shower and thunderstorm chances continue Thursday night ahead of
an approaching cold front. Precipitation may end as a wintry mix
later Friday as the front moves through and colder air builds into
the region.

Aviation(18z tafs)
Vfr conditions will continue through the night. A lake breeze
developed this afternoon. It's delayed, but still expected to
impact mke for a few hours before shifting southerly again this
evening. Clouds will build into the region overnight as rain
moves into the area Sunday morning. Expect ceilings to gradually
decrease to MVFR late Sunday morning.

Intermittent light rain will persist throughout the day mainly
impacting areas along and south of i-94. Expect gusty northeast
winds and drier air to spread into southern wi in the wake of a
cold front late Sunday afternoon.

Marine
A low pressure system will move over central illinois Sunday and
bring a chance for light rain, or possibly a wintry mix, to
southern lake michigan during the day. A potent cold front will
drop south through lake michigan late Sunday afternoon. Expect
north-northeast gale force gusts in the wake of the front over the
southern two thirds through early Monday morning. We upgraded to a
gale warning.

Quiet conditions are then expected as high pressure builds in
Monday afternoon into Tuesday. Low pressure approaching from the
plains will bring our next chance for gusty southerly winds over
lake michigan Wednesday night into Thursday. Gale force gusts are
possible.

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.
