10/12 – Trey’s “Cloudy & Cool” Thursday Evening Forecast

Meteorologist Trey Tonnessen

Thursday has been a much quieter day, and will remain generally quiet through
the evening. Even with a cold front expected Friday night and
Saturday it will likely remain dry with the forecast being mostly
a temperature focused forecast. These low clouds have been
stubborn and will probably continue to hang around through sunset
and possibly most of the night but are expected to lift and clear
out through the morning hours tomorrow

Zonal flow aloft and high pressure at the sfc will take over tonight
but the LL thermal trough will be very slow to evacuate and is more
so retreating to the north-northwest. This is why these low and mid
clouds have hung around today and likely through a good portion of
the night. Overall Friday and Friday night will be quiet however a
deep low currently moving into the central and northern Plains will
continue east into the Great Lakes by Saturday while a strong s/w
on the backside starts to dive southeast out of Canada into the High
and northern Plains Friday night. The main low will help to drive
a cold front through the area overnight Friday and early Saturday
while the secondary s/w will help to dig and develop the L/W
trough that will develop across the eastern CONUS by Monday. The
cold front will bring in cooler and drier air but it could be late
enough in the day allowing highs to still get into the upper 70s
and lower 80s. However, the cold air advection will continue
through the night leading to a much cooler Sunday. That said, the
work week could begin even cooler as that previously mentioned S/W
will help to usher in a reinforcing cold front Sunday afternoon
and night.
