a backdoor (ne to sw movement) front was moving across lower mi
in response to a closed wave moving through the anchored ne us
trough. while it will come through with only some high clouds,
temperatures will end up 5 to 10 degrees colder (coldest ne) and
winds will have a bit more kick today in the wake of the front.
the wave will move away, but the overall upper flow will shift
west somewhat and force the omega block setup west as well.
temperatures will still be very seasonable in the 70s, but the
80s will be more confined to sw areas until it shifts back east.
as we head into the latter part of next week and the weekend,
models agree on the blocky pattern breaking up with a semi-zonal
flow and eventually indications of a northern stream wave
moving in for the weekend. in the lower levels, thermal and
moisture profiles will increase, resulting in a return to highs
into the 80s thursday into the weekend, higher humidity and
eventually increasing chances for showers and storms.

front has passed through both sites with a ne wind now
dominating, which will increase during peak heating somewhat.
otherwise, little more than some high clouds are expected
through the period.
