Weather Summary

Weather Underground midday recap for Thursday, May 23, 2013.

Severe storms developed over the Southern Plains from northern Texas through northern Oklahoma on Thursday. A trough of low pressure lingered over the region, which pulled moisture and energy in from the Gulf of Mexico. This allowed for showers and thunderstorms to develop in these areas, some of which turned severe with large hail, damaging winds, and periods of heavy rainfall. A brief tornado was reported near Cedar Hill, Texas. Hail 2.5 inches in diameter was reported near Davis, Oklahoma and 65 mph winds were reported at Newcastle and Dickson, Oklahoma. Rainfall totals varied over 2 inches with this system. Oklahoma City reported a mid-day total of 2.92 inches of rain.

Meanwhile in the East, a trough of low pressure over the East Coast allowed for a strong cold front to stretch from the Northeast through the Eastern Valleys. Moisture ahead of this front allowed for showers to develop from the Carolinas through Maine, with some areas of thunderstorms. There was a slight chance that these storms would turn severe from Virginia through New Hampshire, but severe storms have not developed.

Meanwhile Out West, a low pressure system mover the Rockies maintained widespread showers across the Pacific Northwest and Northern Rockies. Strong winds developed ahead of this system from eastern Montana through western Colorado. Gillette, Wyoming reported maximum winds up to 56 mph.
