Weather Underground midday recap for Tuesday, July 23, 2013.
Wet and unsettled weather continued for the East on Tuesday. In the north, an area of low pressure trekked eastward through southeastern Canada and began to lift north-northeastward through Quebec, while frontal disturbances associated with the system advanced into the eastern third of the nation. An associated warm front lifted through northern New England with a wave of low pressure, triggering showers and chances of thunderstorms. Behind this activity, an associated cold front moved eastward through the Midwest and reached from the Great Lakes through the Ohio Valley and into the Central Plains by the afternoon. Strong to severe thunderstorms became possible along and ahead parts of the cold front in the afternoon and evening hours. The Storm Prediction Center issued a slight risk of severe thunderstorm development for parts of Kansas and Oklahoma, into the Lower Mississippi and Ohio Valleys. Meanwhile, numerous scattered showers and thunderstorms were expected in the Mid-Atlantic and parts of the Southeast.
Elsewhere, an upper level disturbance kicked up rain and strong thunderstorms with chances of hail and damaging wind in the Northern HighPlains, while monsoonal moisture triggered showers and thunderstorms across the Desert Southwest, the Sierra Nevadas, and parts of the Central Great Basin.
Temperatures in the Lower 48 states Tuesday have ranged from a morning low of 32 degrees at Stanley, Idaho to a midday high of 104 degrees at Elkhart, Kansas
