east and interior, varying from 4 inches in tlie lower Missis- 

 sippi valley to 2 inches at the Atlantic coast. 



Week ending May 20. — The extensive area of high pres- 

 sure and attendant cold, central over North Dakota and east- 

 ern Montana the first of the week, moved slowly southward 

 over the Rocky Mountain and Plains region during the early 

 part of the week, accompanied by frosts in the more exposed 

 localities. Its influence was felt in lower temperatures in 

 the central valleys. Over the far northwest warm weather 

 continued. The latter part of the week continued cool in the 

 Ohio valley and over the middle Gulf States ; in the remain- 

 ing portions of the country the temperature had risen to near 

 or above the normal. As a whole, the week was unusually 

 cool in the interior. Along the immediate Atlantic coast the 

 temperature was near the normal, being somewhat above over 

 eastern New England; westward from the Rockies it was 

 warmer than the average. A storm central over the St. Law- 

 rence valley the first of the week caused rains over New Eng- 

 land and portions of the lower Lake region Monday and Tues- 

 day. By Thursday unsettled weather prevailed over the 

 entire country east of the Mississippi, with the exception of 

 New England and northern New York. By Friday the storm 

 had moved to the upper St. Lawrence valley, and rain had 

 fallen generally throughout the north Atlantic States and in 

 the lower Lake region. The middle and latter portions of the 

 week were mostly without rain over the great central valleys. 

 The total fall for the week exceeded 1 inch along the Atlantic 

 coast northward and much of Florida. Over most of the re- 

 maining portion of the country there was less than ^ inch, 

 and considerable areas had no appreciable rainfall. 



Week ending May 27. — Eastward from the Rocky Moun- 

 tains the week opened comparatively cool in the northern tier 

 of States, while a change to considerably warmer weather 

 was in progress in the south. West of the Rockies the tem- 

 peratures were becoming more nearly normal. As the week 

 advanced there was a general increase in temperatures over 

 the central and eastern districts, until Thursday, when cooler 

 weather temporarily overspread the middle Atlantic States
