.SHORT TERM...(This evening through Wednesday)
Issued at 252 PM EDT TUE AUG 9 2022

High pressure over the Lower Great Lakes has yielded another Chamber 
of Commerce Day across the U.P. with temperatures in the mid/upper 
70s, dewpoints in the 50s, and a nice southwesterly breeze. A 
moisture starved cold front over far northwest Ontario will continue 
to drop southward this evening and through the area early Wednesday. 
With southwest winds expected to stay up overnight tonight, 
temperatures won't fall off as quickly tonight and should bottom out 
in the 50s to around 60.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 252 PM EDT TUE AUG 9 2022

Cold front will pass through the area early Wednesday. With lack of 
moisture and timing of front no precipitation will accompany it's 
passage, maybe just a few mid level clouds. 85H temps fall from 
around 18C early in the day to 10C by the end of the day. High 
temperatures will be right around their seasonal norms in the 70s 
except over the south central where the cold advection effects will 
take longer to reach and highs will be in the 80s there.

High pressure will continue to build southward across the Upper 
Great Lakes though Friday. With 85H temps falling to 5-8 C, highs 
will top out around 70 for most with plenty of sun. Thursday night 
is shaping up to be a pretty chilly night with high overhead and 
very dry air. Lows in the upper 30s across the interior west seem 
quite likely with low to mid 40s elsewhere. 

Temperatures will quickly rebound on Friday to seasonal level under 
abundant sun.

Saturday into early next week, a series of shortwaves dropping into 
the eastern upper trough should support some convection at times. 
Expect coverage of convection to be limited to isolated to scattered 
at best. Most locations will be dry most of the time, and some 
locations likely won't see any pcpn during this time frame. Best 
chance of precipitation will be ahead of the daily Lake Superior 
lake breeze as it moves inland...especially Saturday. Temperatures 
will be seasonable over the weekend into early next week.

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 252 PM EDT TUE AUG 9 2022

A cold front approaching from the nw will cross Lake Superior 
tonight and early Wed morning. Ahead of the front, sw winds will 
increase and gust to as high as 25kt later today over western Lake 
Superior, mainly at high obs platforms. These stronger wind gusts 
will then shift to eastern Lake Superior this evening. Winds will 
shift to nw with gusts under 20kt after the front passes. As high 
pres begins to build toward Lake Superior on Wed, nw winds over far 
eastern Lake Superior may gust up to 25kt in the aftn. Winds across 
Lake Superior should then remain under 20kt through the weekend.
