.DISCUSSION...(This evening through Friday)
Issued at 432 PM CDT Sat Aug 13 2022

Summary: Northwesterly flow will lead to periodic chances of
rainfall through the period along with seasonal temperatures.

High pressure was centered over the Northern High Plains this
afternoon with an area of low pressure near La Crosse. This low
continued to spread stratus across much of the Northland with
drizzle being reported at times underneath this deck. Some
clearing was seen from the Iron Range northward. This area of
clearing will slowly work across the region tonight and tomorrow.
With abundant low level moisture in place, areas of fog are
expected to develop tonight. This fog may be dense in spots and
will need to be monitored for any possible Dense Fog Advisories.

Northwest flow will setup over the region for much of the week
before an upper low disrupts the flow late week. Weak impulses
rippling through the flow will lead to showers and isolated
rumbles of thunder during the afternoon hours Sunday through
Thursday. No severe weather is currently expected along with no
widespread significant rainfall during this period. Slightly
better chances for rainfall will be seen at the end of the week
potentially with models bringing an upper level low through the
area.

Temperatures will be near seasonal levels through the week with
highs in the 70s and lower 80s. Areas near Lake Superior will be
cooler with light onshore winds expected each day.
