Week endiufj May IG. — Temperatures were slightly 

 above normal until the middle of the week, when an area 

 of high pressure, with severe frosts, moved southward and 

 eastward from Canada, and dominated the conditions ■'^or 

 all districts east of the llocky Mountains for the remainder 

 of the week. The week closed with a marked drop in tem- 

 perature from the northern Rockies westward to the Pacific 

 coast, with temperatures at or below freezing and snowfall 

 in the middle Rockies. For the week, as a whole, the pre- 

 cipitation was below the normal in nearly all districts, the 

 deficiencies being most marked in the Gulf and Atlantic 

 States, upper Mississippi valley, and Lake region. 



Week ending May 2S. — The mean temperature for the 

 week was again below the normal over the districts be- 

 tween the Rocky and Appalachian Mountains, except in the 

 Lake region, where there was a slight excess. During the 

 early part of the week the weather was decidedly cool over 

 ISew England and portions of the Middle Atlantic States. 

 There were frequent and copious rains over most of the 

 districts east of the Rocky jMountains. Over, the east Gulf 

 and Atlantic coast States the precipitation, though fairly 

 generous in amount, was nevertheless below the average 

 for the season. West of the Rocky Mountains the amounts 

 were universally less than the average. 



Week ending May 30. — The week opened with a con- 

 tinuation of cool weather over the great agricultural districts. 

 A high barometric j)ressure moved slowly eastward, gradu- 

 ally displacing the showery, rainy weather previously, but 

 accompanied by temperatures close to freezing. West of the 

 Rocky Mountains the weather continued warm, the tempera- 

 tures increasing with the advance of the week. Showery 

 conditions moved eastward during the first two or three days 

 of the week. Over the Rocky Mountain and Great Plains 

 States generally clear weather prevailed, except for showers 

 in some sections near the end of the week. Local showers 

 prevailed from the Lake region eastward and southeastward 

 to the Atlantic coast.
