Weather Underground midday recap for Monday, July 08, 2013.
Hot, humid, and wet conditions continued in the East on Monday, while hot and unsettled weather continued in portions of the West.
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 continued scattered showers and thunderstorms from parts of the Gulf Coast northward into the Midwest and Northeast. A stalled frontal disturbance extending across the Upper Great Lakes and the northern tier of the Northeast also supported rain and storms through the afternoon and evening. Areas of heavy rainfall remained possible in organized storms in the Midwest and Southeast, while severe storms with damaging wind gusts were possible in northern Indiana, northwestern Ohio, southern Lower Michigan. Elsewhere in the East, daytime temperatures remained a few degrees above average from southern New England to Virginia with as highs climbed into the upper 80s and 90s.
Out West, hot conditions continued for the region as an upper high remained situated over New Mexico. Chances of scattered showers and thunderstorms continued in the Four Corners through the Northern Rockies due to monsoonal moisture. Rich low level moisture and favorable instability created a slight risk of severe thunderstorm development from Montana through Iowa from this afternoon through Monday night. Damaging wind gusts and hail were possible with storms in this region.
Temperatures in the Lower 48 states Monday have ranged from a morning low of 37 degrees at Stanley, Idaho to a midday high of 113 degrees at Needles, Calif.
