crossed the country during the entire week, and such rain as 

 occurred was confined to light local showers, with occasional 

 heavy falls in connection with thunderstorms. At the begin- 

 ning of the week showers were reported from the Lake region 

 eastward to the Middle Atlantic States and New England, 

 and a few heavy falls occurred in the middle Missouri val- 

 ley. During the remainder of the week showers were light 

 and widely scattered, save in the upper Lake region, near the 

 south Atlantic coast, in the northwest and along the Pacific 

 coast, where local heavy rains occurred during the middle 

 and latter part of the week. For the week as a whole the 

 precipitation was probably the least for any like period of 

 the season. From the Rocky Mountains eastward there was 

 nearly everywhere a deficiency in the rainfall, excesses oc- 

 curring only over small areas in the middle Missouri valley, 

 the upper Lake region, portions of New England, New York, 

 Pennsylvania and Maryland, and locally at a few places in 

 the South Atlantic and east Gulf States. 



Weeh ending September 16. — The high pressure in the 

 far northwest at the beginning of the week advanced to the 

 northern Rocky Mountain region by Tuesday morning, and 

 a change to cooler weather overspread all northern districts 

 from the upper Mississippi valley westward, and at the same 

 time low temperatures had penetrated to the middle and 

 southern Plateau regions, with frosts at exposed points. 

 The high-pressure area developed considerably by Wednes- 

 day morning, its influence extending over all northern and 

 central districts from the Lake region westward, but there- 

 after its intensity diminished, and only moderately cool 

 weather attended its progress over the more eastern districts. 

 For the week as a whole the mean temperature continued 

 above the normal from the eastern portions of the Great 

 Plains region to the Atlantic coast, the region of greatest 

 excess extending from southwestern Texas northwestward 

 to southern New England. At the beginning of the week 

 local rains were in progress over the South Atlantic and east 

 Gulf States and in the upper Lake region, upper Mississippi 

 valley and in the mountain districts of the west. Showers 

 continued in the southeastern States during much of the
