Weather Summary
Weather Underground midday recap for Friday, May 24, 2013.

Heavy rainfall and strong thunderstorms developed over southern Texas and northern Mexico on Friday, as onshore flow from the Gulf of Mexico maintained warm and humid conditions. Rainfall totals reached over 2 inches by mid-day for the region. Uvalde, Texas saw a mid-day total of 2.06 inches of rain. Wind gusts up to 50 mph also accompanied this system.

To the north, showers and thunderstorms developed over the Plains as a broad low pressure system moved off the Rockies and into the Plains. This pushed a warm front eastward, which allowed for showers and thunderstorms to pop up from North Dakota through Kansas. These storms have not yet turned severe but there was a slight chance of severe thunderstorm development across northeastern Colorado and into western Kansas and Nebraska. Large hail and strong winds were likely in these areas, with possibly a tornado or two.

Meanwhile in the East, a trough of low pressure and associated cold front allowed for showers and thunderstorms to persist from the Mid-Atlantic states through Maine. Strong winds and heavy rainfall were reported from Pennsylvania through Maine. Out West, a trough of low pressure over the Pacific Northwest kicked up a few more scattered showers across Washington and Oregon, which moved into Idaho and western Montana.
