During the holiday weekend, the models are in good agreement that a
strong mature low pressure system over Manitoba slowly meanders
eastward toward the Great Lakes region. This system will bring an
unsettled weather pattern to the Northern Plains as several rounds
of weak upper disturbances push through. Model confidence is low
regarding timing/location of these impulses, but they will
ultimately result in a mix of sun and clouds and some isolated light
showers in the area for Saturday afternoon/night, with better shower
coverage and perhaps a few storms Sunday through Monday night.
Additionally, conditions will be breezy for Sunday and Monday as the
surface low moves by to the east. By Tuesday, this system will be
over the Great Lakes region and rain chances will diminish as high
pressure begins to build into the Dakotas.

Temperatures will be near normal values with diurnal swings each day
through the weekend and into early next week. Highs will be in the
60s to lower 70s Saturday and Sunday, becoming slightly cooler
Monday. Lows will be in the 40s to lower 50s.
