Weather of the week continued from page 628. 



TEMPERATURE : The weekly mean temperatures averaged slightly above normal west 

 of the Rocky Mountains over the western edge of northern and central Great 

 Plains and along the eastern portion of the gulf coast. The high-pressure areas, 

 one over the Pacific Northwest and the other over the Great Lakes spread fair 

 skies and early autumn temperatures from the Pacific coast to New England. 

 Some northern localities were 15-20° cooler Monday morning than 24 hours earlier. 

 The temperature at Marquette, Michigan, was 46° Monday and 64° Sunday. Cool 

 weather did not reach South Dakota until a day later. Numerous stations in South 

 Dakota registered 100° or higher Monday. Pierre recorded 106° Monday. Maximums 

 in South Dakota Tuesday were generally in the 80 's and 84° at Pierre. Freezing 

 weather occurred in the high Rockies and at some northern locations. Big Piney, 

 Wyoming, registered 26°, Yellowstone, Montana, 32°, and Pellston, Michigan, 32 

 Tuesday morning. A warming trend occurred over much of the Nation late in the 

 week. Miles City, Montana, registered 100° and Minot , North Dakota, 101° 

 Saturday afternoon. Maximums over the Northeast held mostly in 60 's and low and 

 middle 70 's Friday, due to cloudiness and rain associated with Tropical Storm 

 Doria. The Northeast warmed to near or above 80° by Sunday. The maximum exceeded 

 100° every day in the southwestern deserts, reaching 107° at Imperial, California, 

 Wednesday and Thermal and Blythe Sunday .
