A lot of wet weather and even a few severe storms are possible across the country through this weekend.
First, a low-pressure system with a cold front draped to the south and west begins early today in central MN and makes it to the MN/IA border by this evening, to the IA/IL border near the MS River by Saturday evening, and then to the Eastern Great Lakes region by Sunday evening. Scattered showers and storms are likely in the vicinity of the front and within the circulation of the low across much of the Midwest, Great Lakes, and Ohio River Valley. A few of the storms ahead of the low and near the front could become severe with hail as the main threat given the elevated nature of the storms. The severe threat will be in eastern IA/northeast MO/northwest IL this evening, from central MO to northern OH Saturday, and from southern MO to the eastern Great Lakes on Sunday.
Next, a stationary front will be draped from northern TX to the Carolinas through the weekend. The better chances for scattered showers and storms will be close to this front, however, a few isolated storms could develop further north at times during the weekend into the Mid-Atlantic and New England states.
Finally, the monsoonal pattern continues in parts of the west with isolated to scattered showers and storms likely for AZ, NM, ID, east and south NV, west WY, west CO, and west TX. Flooding could become an issue in AZ, NM, and the El Paso area in TX as a Flood Watch goes into effect this afternoon in these regions.
