.SHORT TERM...(This evening through Thursday night)
Issued at 320 PM CST Wed Nov 13 2019

Regional radar continued to show an overall decrease in areal
coverage and intensity of the precipitation across southern
Minnesota, and into west central Wisconsin this afternoon. Based
on satellite trends, and radar, the precipitation will end by
late afternoon, with some lingering light snow/flurries in far
south central Minnesota, or portions of west central Wisconsin
around Eau Claire until early evening. Otherwise, the main short
wave will move across the region, with drying taking place in the
wave of the short wave. However, the cyclonic circulation around
the departing short wave, should hold onto the cloud cover across
eastern Minnesota and western Wisconsin until late tonight, and
possibly holding in western Wisconsin through sunrise. Currently
models are holding back the cloud cover across eastern
Minnesota/western Wisconsin until Thursday afternoon. This will
have an affect on temperatures which could hold down these
readings a few degrees cooler than forecast. Another cold front
will arrive late Thursday night and bring more cloud cover to the
region. Moisture depth is limited to the boundary layer, so I am
not expecting anything more than a flurry or sprinkle.

.LONG TERM...(Friday through Wednesday)
Issued at 320 PM CST Wed Nov 13 2019

No significant changes from the previous forecast. A large area
of surface high pressure extending across the entire Mississippi
River Valley up into Canada will keep the region dry on Friday.
This area of high pressure will shift eastward on Saturday and
southerly flow will develop across the Upper Midwest ahead of a
weak shortwave trough that will bring a chance for some light rain
or snow Saturday night into Sunday. Forecast soundings show pretty
shallow saturation and weak omega, so confidence isn`t to high on
precipitation, and those that did see any rain of snow will have
very light amounts.

Looking ahead, another weak wave drops down and bring a small
chance for some light precipitation late Monday which could linger
into Wednesday. These are subtle, small scale features so did not
deviate from the blended guidance. Temperatures will be near or
slightly above the seasonal average for mid-November.


.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1041 PM CST Wed Nov 13 2019

MVFR ceilings remain spread over much of MN/WI at TAF
initialization time. As the overnight hours progress, this lower
cloud shield will shift off to the east as the departing cold
front drags them out of the area. This will allow for mainly
FEW/SCT high cirrus during the day Wednesday with no
precipitation. Winds will gradually back from NW to SW with
speeds mainly in the 5-10kt range.

KMSP...MVFR ceilings in the 2k-3k ft range will remain in place
into the early morning hours then should scatter out just in time
for the Thursday morning push. Solid VFR conditions expected
through Thursday evening with winds about 300 direction in the
morning then more of a crosswind component expected for the

Fri...VFR. Wind E 5 kts.
Sat...MVFR ceilings likely. -RASN possible late. Wind S 10-20
Sun...MVFR ceilings possible early. Wind NW 5-10 kts.
