Weather Underground midday recap for Tuesday, July 09, 2013.
Hot, humid, and wet conditions continue for parts of the Eastern Seaboard on Tuesday, while active weather picked up in the Central and Midwestern U.S.
In the East, an area of high pressure spanning across the Southeast into the western Atlantic Ocean maintained southerly flow from the Gulf of Mexico into the region. As moisture streamed in from the south, warm and moist conditions combined with daytime heating led to areas of scattered showers and thunderstorms from parts of the Southeast northward into New England. Meanwhile, daytime temperatures will remain a few degrees above average in the Mid-Atlantic as highs climb into the upper 80s and 90s.
Behind this activity, a cold front with a wave of low pressure organized over the North-Central U.S. and trekked eastward toward the Midwest through the day. Sufficient moisture and energy ahead of this disturbance supported showers and thunderstorms with possible severe thunderstorm development. The Storm Prediction Center issued a slight risk of severe thunderstorms from eastern Nebraska and northern Kansas into the Upper Great Lakes and western Ohio Valley through Tuesday night. Damaging wind gusts and large hail were possible with severe storms in the region.
Out West, hot conditions continued over parts of the western interior due to prevailing high pressure. Chances of scattered showers and thunderstorms also continue in the Four Corners due to monsoonal moisture.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 35 degrees at Stanley, Idaho to a midday high of 107 degrees at Great Bend, Kan.
