WEATHER OF THE WEEK ENDING JULY 26 



Reprinted from Weekly Weather and Crop Bulletin supplied by Environmental Data 

 Service, NOAA. 



HIGHLIGHTS : High temperatures prevailed in the Far West and along the Gulf of 

 Mexico. The Northeast was mostly cool and comfortable. Thundershowers were wide- 

 spread over the Central and East. 



PRECIPITATION : A large cool high covered much of mid-America early in the week. 

 A front stretched from the northern Atlantic States to the southern Great Plains. 

 It was the battle line which marked the leading edge of the cool dry air, which 

 pushed in from the north to replace the retreating warm humid air that lay over 

 the South. A line of showers and thunderstorms occurred along the front. Some of 

 the thunderstorms were accompanied by torrential downpours, strong gusty winds, 

 or hail. A few tornadoes dotted the open country in Ohio, .Louisiana, and Georgia. 

 Bridgeport, Connecticut, received 5.95 inches of rain the 24-hour period ending 

 Tuesday morning. Light scattered precipitation occurred in the Rocky Mountains 

 Wednesday, in the Great Plains Thursday, from northeastern Texas to the Great 

 Lakes Friday, and from Louisiana to New England Saturday. Most of the weekend 

 showers occurred in the vicinity of a slow moving cold front that stretched from 

 the Northeast to the southern Great Plains. At times, lines of thunderstorms 

 marked the position of the front. Some of the thunderstorms produced hail and 

 strong winds. Other thunderstorms dotted the warm humid Southland. Weekly 

 precipitation totals were generally less than 0.50 inch over the western half of 

 the Nation and ranged widely from 1 inch to locally 5 to 6 inches or more over 

 the eastern half of the Nation. 



TEMPERATURES : Hot sunny weather prevailed over the Western States early in the 

 week . On Tuesday, the mercury reached 107° at Yakima, Washington, and 108° at 

 Red Bluff, California, 100° or higher over the southwestern deserts, and the 90's 

 across the South to the Atlantic Ocean. By Wednesday afternoon, the temperatures 

 in parts of the deserts had gone above 110°. The heat in the Southwest was 

 especially oppressive because of the unusually high relative humidity in the area. 

 In sharp contrast to the hot weather in the Far West and across the South, weather 

 over the rest of the Nation was quite comfortable. A large high covered the 

 central Great Plains. It brought cooler weather to a large area extending from 

 the Rocky Mountains to the Appalachians. Afternoon temperatures remained in the 

 Weather of the week continued on page 548.
