Forecast discussion for routine morning forecast issuance

.SHORT TERM...Today...Tonight...and Tuesday
Issued at 343 AM CDT Mon Apr 23 2018

Overall quiet weather expected for the start of the new work
week.

A west to east surface high pressure ridge anchored over the
Great Lakes region today into Tuesday will continue to bring near
normal temperatures, dry weather and sunshine over most areas
today. The air mass has been so dry that overnight fog has not
developed despite the snow melt. However some patchy fog was
showing up over minnesota early this morning.

Some high level clouds may brush parts of east central Wisconsin
later today into tonight as a slow moving storm system drifts
over the ohio valley/Tennessee region.  Meanwhile mid to high
level clouds with a northern stream frontal system over Northern
Plains may work into northwest Wisconsin tonight.

More clouds are expected Tuesday as the upper ridge flattens and
the Northern Plains frontal system sags into the state. There is a
chance for light showers in the afternoon as the front slides
southeastward over the state.

Temperatures cool a little behind the front, but a warm tuesday
morning start will allow temperatures to reach normal levels over
east central Wisconsin.

.LONG TERM...Tuesday Night Through Sunday
Issued at 343 AM CDT Mon Apr 23 2018

Two weak systems to deal with during the period. The first system
will be exiting the area Tuesday evening, thus a small chance of
rain showers was warranted across northeast Wisconsin. The second
system arrives Thursday afternoon and lingers into Thursday night.
This system should bring mainly rain to the area. If precipitation
lingers longer into the night, it could end up as a little snow
across the far north. Otherwise, Wednesday may end up being another
very dry day with humidity readings below 30 percent across the
north.

Temperatures throughout the period should be at or slightly below
normal. There are some indications that the warmest day of the
year may be possible early next week. Stay tuned!.

.AVIATION...for 06Z TAF Issuance
Issued at 1120 PM CDT Sun Apr 22 2018

VFR conditions with light winds will prevail through the TAF
period. The very dry airmass in place continues to prevent fog
development during the overnight hours. Some mid and high clouds
may spread in from the southwest Monday evening and overnight as a
low pressure system passes well to the south.

.HYDROLOGY...
Issued at 343 AM CDT Mon Apr 23 2018

Rivers levels continue to rise with the runoff from
the snow melt. There are a few chances of rain this week, Tuesday
afternoon and then again toward Thursday afternoon and Thursday
night. Both systems are not expected to generated much rainfall,
so run off will be mainly due to the snow melt this week. The
upcoming weekend looks dry as well.
