Weather Underground midday recap for Thursday, May 30, 2013.

Severe thunderstorms continued across the Plains on Thursday as a strong low pressure system slowly moved over the Northern Plains. Flow around the system created a warm front that stretched eastward across the Upper Midwest and into the Great Lakes, while a cold front extended southward into the Southern Plains. Warm and humid air filtered in between these two systems from the Gulf of Mexico, which allowed for thunderstorms to develop from the southern Plains through the Great Lakes. Some of these storms turned severe with heavy rainfall, large hail, and strong winds. Heaviest rainfall was reported at Coffeyville, Kansas with a mid-day total of 3.29 inches of rain. Large hail was reported at Silo, Oklahoma and strong winds were reported across the region. A wind gust up to 60 mph pushed a car off a road in Coffeyville, Kansas. While tornadoes have not yet developed, this system has a history of producing tornadoes. Thus, Tornado Watches have been issued from Wisconsin through Oklahoma.

At the same time, the northern side of this system brought more rain showers to the Northern Rockies and the Northern Plains. Rainfall totals ranged from 1 to 2 inches across the region, which increased flooding for most of eastern Montana and western North and South Dakotas. Further west, a trough of low pressure over the Pacific Northwest maintained a few scattered showers from Oregon and Washington.

Temperatures in the Lower 48 states Thursday have ranged from a morning low of 24 degrees at Monarch Pass, Colo. to a midday high of 97 degrees at Needles, Calif.
