NATIONAL WEATHER SUMMARY:
Across the East, numerous showers and thunderstorms were found gradually lifting northward ahead of a very slow moving area of low pressure over southern Missouri. Shower and storm activity extended from the Mid-Mississippi Valley, over to the southern Mid-Atlantic region, and southward to the Gulf. Generally storms were not severe. However, golf ball sized hail was observed in northern Florida, while isolated wind gusts in storms up to 65 mph occurred throughout the Southeastern US. Rainfall amounts generally ranged from 0.25 to 0.75 inches, though with areas of stronger storm activity, totals up to 1.50 inches were common. Locally heavy rainfall resulted in ponding on roadways.
Through the center of the country, a developing low pressure system moved through the Dakotas, dragging a cold front through the High Plains.
This front sparked scattered showers and thunderstorms from the eastern Dakotas, south to the Texas panhandle and western Oklahoma. By the afternoon, isolated to scattered storms had also developed throughout western and southern Texas. Storms were generally not severe, though isolated storms through Texas produced hail up to one inch. A single observation of golf ball sized hail was reported northwest of Laredo, Texas as well. Two land spout tornadoes formed early in the afternoon as storms strengthened over eastern Colorado and western Kansas, though no damage was reported. Rainfall amounts of 1 to 2 inches were reported with the thunderstorm activity in the Plains and Upper Midwest.
In the West, shower and thunderstorm activity was isolated to widely scattered through the Rockies and Great Basin. Most storms remained non-severe, though wind gusts up to 62 mph were reported within storms in southeastern Arizona. Meanwhile, dry conditions continued across the far western states.
