forecast discussion for routine afternoon forecast issuance

Short term Tonight and Monday
issued at 237 pm cdt Sun oct 22 2017
the main forecast concerns will be timing the return of clouds
later tonight and extent of precipitation chances on Monday.

The 19z msas surface analysis showed the cold front responsible
for today's rain extended from eastern lake superior to near
chicago. Post-frontal rains still existed over most of northeast
wi, although drier air was working into central wi and the rain
was diminishing to sprinkles. A ridge of high pressure was located
from the central plains into the upper ms valley with clear skies.

Farther upstream, visible satellite imagery was already picking up
the next batch of clouds over the dakotas associated with our next
weather maker.

Scattered showers will exit far eastern wi early this evening as
the ridge of high pressure moves across wi and advects drier air
into the region. Skies will clear over the forecast area tonight,
however the next cold front shortwave trough combination is
forecast to already be diving southeast across the dakotas into
the upper ms valley after midnight. Mid high clouds should also be
on the increase across north-central parts of central wi during
the pre-dawn hours. Min temperatures are expected to range from
the middle to upper 30s north, upper 30s to lower 40s south.

As this shortwave trough continues to dig southeast into the
western great lakes midwest on Monday, the cold front will quickly
sweep across wi. Despite favorable dynamics aloft and lift from
the front, moisture is lacking as gulf moisture to be tied to a
system lifting northeast into the eastern great lakes. Look for
clouds to increase thicken across northeast wi on Monday and will
continue to mention a small chance pop in the forecast due to the
strong mid-level forcing. MAX temperatures to range from the
middle 50s north, upper 50s south.

Long term Monday night through Sunday
issued at 237 pm cdt Sun oct 22 2017
a strong low pressure system will track through the central great
lakes region Monday and Monday night, then stall out over the
northern great lakes Tuesday and Tuesday night. Despite being
closer to the system affecting the area, nwp models are actually
in less agreement regarding the systems effects on the western
great lakes region. The main sticking point appears to be the
phasing of the southern stream system lifting north from the
southern mississippi valley and the northern stream system
tracking east through the western great lakes region. Despite the
model differences it appears the area is in for some rain and wind
as the pressure gradient tightens Tuesday and Tuesday night. How
these systems phase will make an impact on how much rain and how
windy conditions get across the region. At this point it appears
the highest wind gusts will be over door county due to deeper
mixing over the warm waters of the bay and lake michigan, where
gusts could get over 40 mph.

After a brief break in the action late Wednesday and Wednesday
night, two low pressure systems will track through the region
late in the week and into next weekend. These systems will bring a
continued chance for showers to the region. Given the cold air in
place they could also bring some accumulating snow to northern
wisconsin during this period. However since these systems will be
quick moving and the warm ground in place, snowfall amounts are
expected to be fairly light. Nwp models this far out continue to
show significant differences, so confidence in this part of the
forecast is fairly low.

Aviation For 18z TAF issuance
issued at 1148 am cdt Sun oct 22 2017
occasional showers will continue to affect mainly eastern wi this
afternoon as a cold front pulls away from the region. CIGS will be
MVFR under these showers, however a ridge of high pressure
building east from the upper midwest is expected to end the
showers across central wi by mid-afternoon with a gradual decrease
in clouds thereafter.VFR conditions are forecast through tonight
with clearing skies for most locations. The approach of an upper
trough and cold front later tonight into Monday will bring an
increase in clouds once again with a small chance of showers on
Monday across all of northeast wi. CIGS should remain low-endVFR
on Monday with the showers in the vicinity, especially during the
afternoon hours.

Marine
Issued at 237 pm cdt Sun oct 22 2017
gusty west winds and high waves are expected to continue across
the lake michigan nearshore waters during the early evening hours.

A small craft advisory is in effect for these areas this evening.

A strong low pressure system will track through the great lakes
early in the work week. A tightening pressure gradient across the
western great lakes region will cause gusty northwest winds
Tuesday and Tuesday night. Conditions hazardous to small craft are
expected during this period, with gale force winds possible.

Although no headlines are in effect for this system, they are
likely to be issued in subsequent forecasts.

Grb watches warnings advisories
None.

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.
