Weather Underground midday recap for Thursday, June 20, 2013.
Severe thunderstorms developed over the Northern Plains and Upper Midwest on Thursday as a low pressure system over the Northern Rockies and western Canada pushed a frontal boundary eastward into the Plains. The warm front associated with this system extended into the Dakotas and Minnesota and kicked up scattered showers and thunderstorms. There was a slight chance of severe thunderstorm development with this system from the Dakotas and Nebraska through western Wisconsin. Quarter size hail and wind gusts up to 50 mph were reported near Fillmore, North Dakota. At the same time a cold front extended southward from this system through the Central Plains and Rockies. A few light and scattered storms developed in these areas, but strong winds remained the main concern in these areas. High fire danger persisted ahead of this system across the Four Corners due to more gusty winds with warm and dry conditions.
In the Northwest, the back side of the low pressure system maintained wet and showery conditions across the Pacific Northwest and Intermountain West. Rainfall totals over the region ranged from 0.5 to 0.75 inches. In the Southeast, a lingering frontal boundary brought a few more scattered showers and thunderstorms to the Southeast and Gulf Coast. Ft. Lauderdale, Florida reported a mid-day total of 2.21 inches of rain.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 24 degrees at Truckee, Calif. to a midday high of 102 degrees at Tucson, Ariz.
