Forecast discussion for routine morning forecast issuance

.SYNOPSIS...
Issued at 344 AM CDT Sat Jun 23 2018

Other than perhaps a few showers in central and north-central
Wisconsin on Sunday, quiet weather with seasonable temperatures
and humidities is expected for the weekend.

The forecast area will remain between the primary branches of the
upper flow into early next week. Subsequently, the flow across
North America will begin to flatten and consolidate before
trending into a western trough/eastern ridge configuration by next
weekend.

Temperatures will remain near seasonal normals for the first half
of the forecast period, then warm to above normal during the
latter part of the period. More humid conditions are expected to
accompany the warmer temperatures. Opportunities for precipitation
will be limited early in the period, then increase considerably
by the middle of next week. Precipitation amounts for the period
will probably end up AOA normal.

.SHORT TERM...Today...Tonight...and Sunday
Issued at 344 AM CDT Sat Jun 23 2018

Much like the past couple days, high and some middle clouds
wrapping back around the decaying cyclone tracking through the
Lower Great Lakes region will affect the area today and tonight.
The air mass across the area will continue to modify, so highs
today will probably be a degree or two warmer than yesterday at
most locations.

An anticyclone from northwest Canada will shift southeast into the
Hudson Bay region today in the wake of a shortwave rotating
through a northern stream upper trough over eastern Canada. The
cold front at the leading edge of a fresh surge of Canadian air
associated with the anticyclone will begin to stall and dissipate
as it shifts into the area tonight and Sunday. But increased
moisture near the front may be sufficient to allow scattered
showers and a few thunderstorms to develop as the atmosphere
destabilizes Sunday afternoon. The models seem to have latched
onto this, so edged PoPs up a little on Sunday afternoon.
Continued onshore flow off Lake Michigan will probably keep the
east too stable for showers, so confined rain chances to the west.

.LONG TERM...Sunday Night Through Friday
Issued at 344 AM CDT Sat Jun 23 2018

Forecast concerns mainly revolve around precip chances during the
middle of the upcoming week, followed by temperatures.  Models
remain in relatively good agreement for this mid-week system, so
will continue to use a blend of the ecmwf and gfs.

Sunday night through Monday night...A few showers may linger over
north-central WI early in the evening before diurnal instability
dissipates.  Thereafter, will likely see a clearing trend as high
pressure builds in from the north behind a cold front.  This should
set up a nice day on Monday, though will likely see increasing
clouds in the afternoon ahead of a closed upper low that will be
moving east across the central Plains.  Models insist on bringing in
a swath of showers and storms from southwest to northeast across the
region during the late evening and overnight hours.  With some
elevated instability arriving ahead of the system, could see a
quarter to a half inch of rain fall by morning.  Temps during this
period will remain seasonable and made little changes to the
previous forecast.

Rest of the forecast...Periods of showers and storms will continue
on Tuesday into Wednesday as the closed upper low tracks across the
region.  The showers will be most widespread on Tuesday when the
combination of forcing, moisture, and diurnal instability peak. Some
breaks in the rainfall are likely on Tuesday night into Wednesday as
the best moisture transport shifts east of the region.  But after a
few showers on Wednesday morning, think precip chances will be
diminishing through the afternoon.  Once the system exits, zonal
flow will be present across the Great Lakes while a beefy sub-
tropical ridge gradually builds northeast across the mid-Mississippi
Valley.  As mid-level heights rise and winds turn to the south by
Friday, temps will be on the rise through the 80s.  Next weekend
looks quite warm and humid.

.AVIATION...for 12Z TAF Issuance
Issued at 344 AM CDT Sat Jun 23 2018

Generally good flying weather with VFR conditions is expected as
dry air continues to feed into the area at low-levels. Some of the
statistical guidance hinted at fog formation tonight. But after
several days of dry weather don`t think we`ll get anything more
than patchy ground fog, so will leave the fog out of the TAFs.
