The weather map has suddenly turned stormy. Not only do we have the system that will impact the Plains and the Midwest the next few days with heavy rain and severe weather, but we now have tropical storm Karen in the Gulf. The storm is expected to move northeast and make landfall near hurricane force along the Alabama coast Saturday night. The latest forecast can be found here.
While the Gulf coast watches Karen, the Plains and Midwest will be watching a developing storm system. Very moist and warm air for this time of year is moving northward through the center of the nation. Showers and a few storms are along an advancing warm front arching across the Midwest. The front will stall out across the northern Midwest into the northern Plains during the next 24 hours.
During Friday a strong upper level trough will move east from the Rockies out into the Plains. Low pressure will develop over Nebraska Friday afternoon. The combination of the trough, low, and front will set the stage for severe storms over parts of the Plains and Midwest Friday. Heavy rain is also expected through the northern Plains and Midwest, much needed rain in the drought areas. The expected average rainfall through Sunday morning can be seen in the graphic from the NWS.
For the Chicago metro area, a broad area of showers and a few storms will move through late this Thursday morning. Skies should become partly cloudy during the afternoon. For Friday with strong southwest winds and at least partly cloudy skies, highs will jump into the 80s. Our normal high is now down to the upper 60s. Showers and storms will return to the area, possibly late Friday night, but more likely Saturday afternoon and night.
