the roughly north-south boundary between moist air in the Mississippi Valley and dry air on the west side of the Great Plains descending from the Mexican Plateau and Southern Rockies Thunderstorms often form along this line, which moves eastward during the morning and westward in the evening
A boundary which separates warm, dry air from warm, moist air The differences in the two (2) air masses may be significant The dry line is usually a boundary of instability along which thunderstorms form

The boundary between the dry desert air mass of the Southwest U S and the moist air mass from the Gulf of Mexico It usually lies north-south across the central and southern High Plains states during spring and summer The passage of a dry line results in a sharp decrease in humidity, clearing skies, and a wind shift from southeasterly or south to southwesterly or west Its presence influences severe weather development in the Great Plains

A boundary separating moist and dry air masses, and an important factor in severe weather frequency in the Great Plains It typically lies north-south across the central and southern high Plains states during the spring and early summer, where it separates moist air from the Gulf of Mexico (to the east) and dry desert air from the southwestern states (to the west) The dry line typically advances eastward during the afternoon and retreats westward at night
The boundary between the dry desert air mass of the southwestern U S and moist air mass from the Gulf of Mexico It usually lies north-south across the central and southern High Plains states druing the spring and summer months When a dry line passes it results in a decrease in humidity, clearing skies, and wind shift from east/southeasterly to west/southwesterly Its presence influences severe weather development in the Great Plains
