.SHORT TERM...(This evening through Tonight)
Issued at 107 PM EDT MON AUG 8 2022

Radar imagery shows that the last of the rain showers has moved out 
of the east. Therefore, with ridging building in behind the 
shortwave producing these showers, expect dry conditions to persist 
throughout the rest of the day today and tonight. Sky conditions 
should improve this afternoon as the shortwave continues to pull 
away. However, with northerly winds and cool air behind the 
shortwave remaining over us this afternoon, expect highs to get no 
higher than 70 across Upper Michigan, with some spots in the north 
central (near Marquette and Munising) possibly not even reaching 60 
today. Tonight, as the ridging builds in, some radiational fog looks 
to set up over the central and east due to the recent rainfall and 
lack of sunshine this afternoon. The fog may be dense in spots. 
Expect lows to be in the mid to upper 40s in the interior central 
and east, with everywhere else being in the 50s.

.LONG TERM...(Tuesday through Monday) 
Issued at 256 PM EDT MON AUG 8 2022

with a ridge over most of the U.S. 12z Tue. The trough over south 
central Canada will head east and then dig southeast into the lower

In the extended, the GFS and ECMWF show a 500 mb trough in the 
eastern U.S. 12z Fri with a ridge in the Rockies and plains. The

starting Saturday.
