Weather Underground Forecast for Monday, August 05, 2013.
Unsettled weather picks up in the nation¼’s mid-section on Monday as a trough of low pressure dips from Canada into the Northern Plains and the Upper Midwest. Showers and thunderstorms are expected to increase in coverage from the Northern Plains into the Upper Great Lakes and parts of the Ohio Valley through the day. A few storms in southeastern Minnesota, western Wisconsin, and Iowa may produce isolated areas of large hail, damaging wind gusts, and possibly a weak, brief tornado. Severe weather will also become possible across portions of the Central and Northern Plains on Monday. Primary risks for these areas will be large hail and damaging winds through the evening. Meanwhile to the south, moisture pooling along a disturbance extending across the Central and Southern Plains will stir up more rain and thunderstorm activity across southeast Kansas and southwest Missouri into Tuesday, maintaining a week of wet weather conditions. Heavy rainfall totals are expected for areas of southeast Kansas and southwest Missouri and will maintain flood and flash flood concerns throughout the region.
Elsewhere, cool, fall-like weather continues for the Midwest and the Northeast, while showers and thunderstorms continue in Florida. In the West, scattered afternoon and evening thunderstorms are expected in the Southwest as the region¼’s monsoon persists.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of 32 degrees at West Yellowstone, Mont. to a high of 104 degrees at Needles, Calif.
