An unsettled pattern is likely Friday and through the weekend. This
is in response to the initial trough and deep surface low which move
toward the Great Lakes on Friday. Eventually a cooler post-frontal
air mass ensues by Saturday morning. At the same time, the southern
stream begins to undergo some degree of amplification across the
southern U.S. How this system tracks on its eastward trek toward the
Atlantic coast will dictate any notable impacts to the local area.
Random deterministic models show a wintry precipitation scenario for
the second half of the weekend. However, there is still plenty of
uncertainty in this complex pattern that these random signals will
likely show up here and there. Will continue to monitor though.
Arctic high pressure builds across the middle of the nation by early
next week. This sets the stages for a cool start to the next work
week.
