A cold frontal boundary extended from the southern Plains to the Great Lakes on Thursday, while a ridge of high pressure continued to build over the eastern Pacific.
A line of showers and thunderstorms began to develop across the central third of the country as a cold frontal boundary stretched from Oklahoma to Michigan. Flood advisories were issued across the Mississippi Valley, the Ohio Valley and the upper Midwest on Thursday as the heaviest rain moved across Michigan. Meanwhile, this cold front brought cooler temperatures to the upper Intermountain West and the northern Plains, as temperatures dropped 5 to 10 degrees behind the frontal boundary. The southern Plains and the Gulf Coast experienced very warm conditions due to a ridge of high pressure over the Gulf of Mexico.

The eastern third of the country stayed mostly clear of precipitation on Thursday.
A weak low pressure system shifted eastward over the Great Basin and the central Rockies, which produced gusty winds across Colorado. Monarch Pass, Colo., recorded wind speeds of 54 mph, while Buena Vista, Colo., recorded wind speeds of 45 mph.
The West Coast remained very dry on Thursday due to a high pressure system over the eastern Pacific. Temperatures ranged between the 80s and 90s across the Desert Southwest, as Palm Springs, Calif., recorded a midday high of 91 degrees.
