Forecast discussion for routine afternoon forecast issuance

.SHORT TERM...Tonight and Tuesday
Issued at 235 PM CDT Mon Aug 29 2016

The main forecast focus continues to be on precipitation chances
as a cold front slowly moves east across the Upper MS Valley/Great
Lakes over the next 24 hours.

The 19z MSAS surface analysis showed an area of high pressure over
Lower MI, a cold front extended from western Ontario southwest
through central MN to a weak area of low pressure over central SD.
Radar mosaic was generally quiet over WI this afternoon, other
than some chaff that moved into east-central WI.

Anticipate precipitation to remain sparse across the forecast area
this evening due to a lack of focusing mechanism. However, the
approach of the cold front toward central WI late tonight could
bring the next chance of showers and thunderstorms, especially to
north-central and central WI. Even with nocturnal cooling of the
atmosphere, the air mass remains unstable through the night, thus
thunder chances would be necessary although weak shear would
preclude any storms from becoming severe. Also expect to see more
fog for tonight, but amount of cloud cover will ultimately
determine how thick the fog can get. Another mild/muggy night on
tap with min temperatures in the middle 60s north, middle to upper
60s south.

The cold front is forecast to gradually push across the rest of
northeast WI on Tuesday. Air mass to remain warm, moist and
unstable with dew points in the middle 60s to around 70 degrees
with SBCAPES between 1500 and 2500 J/KG. Bulk shear values to
remain weak and with expected cloud cover overhead, this would
severely crimp any storm from turning severe. Therefore, have pops
accompanying the frontal passage with locally heavy rainfall and
brief gusty winds the main threat. Precipitation trends to
diminish from NW to SE in the afternoon with decreasing clouds for
the northwest half of WI. Max temperatures on Tuesday to range
from the middle to upper 70s north, to the lower to middle 80s
south.

.LONG TERM...Tuesday Night Through Monday
Issued at 235 PM CDT Mon Aug 29 2016

Ridging will build in across the western Great Lakes by the middle
of the week, bringing the first fall like temperatures to the
region. Temperatures by Thursday are forecast to fall a good 5
degrees below normal for this time of year with highs in the upper
60s to lower 70s. The next chance for rain could be on Thursday
across the lakeshore counties as models are generating some lake
effect rain showers across Lake Michigan. However not all model
solutions are generating these showers with the best convergence
offshore, therefore will continue with a dry forecast with this
issuance.

The high will provide for a long stretch of dry weather across
the region with rain not introduced back into the forecast until
Sunday. Even this return of precipitation is in question as the
long range models are hinting that the region may not get much in
the way of rain until later Sunday night or even into Monday.

.AVIATION...for 18Z TAF Issuance
Issued at 1236 PM CDT Mon Aug 29 2016

An unsettled weather pattern expected over the next 24 hours
across northeast WI as a warm, unstable air mass to reside across
the Great Lakes. Isolated to scattered showers and thunderstorms
are possible this afternoon mainly due to various outflow
boundaries from earlier storms to our northwest. The set-up is
expected to continue through tonight, along with another round of
fog which could send local visibilities down to LIFR conditions
between 06z-14z Tuesday. A better chance of seeing showers and
thunderstorms will be on Tuesday as a cold front pushes through
Wisconsin. While VFR conditions are expected to be dominant,
MVFR/IFR conditions may exist near any thunderstorm activity.
Winds are forecast to be be S-SW through tonight, then shift to
the W-NW on Tuesday behind the cold front.
