Extensive heat continues to bake Iowa in 100+ degree heat this week and now it will expand east. A very significant and expansive heat wave will continue to effect much of the region. This has become the worst heat wave to impact the central part of the region in many years. A very hot high pressure system continues to be located in the Central U.S. Nebraska, Missouri, Iowa, Illinois will all be feeling the extreme heat with multiple days hitting 100.F with a few spots around 110.F degrees. Future north it will be very hot, although not nearly as hot as just to the south. Southern Minnesota, South Dakota and Southern Wisconsin with highs typically around 90 to near 100.F during the extent of this heat wave. Future north and north of a frontal boundry temperatures will be much more comfortable in the middle 80s to low 90s. Finally a sharp cold front will cool down the entire region on Friday bringing in a serge of much needed relief. The front will spark a few thunderstorms in its wake and some areas may deal with the threat of severe weather with the passing of this front.
Local and Metro ViewsOne last day of very hot conditions!
Wednesday we turn up the heat again for the area, but thankfully this will be the last day of very hot conditions at least for a little while. Wednesdays temperatures depend on cloud cover and rain chances but under a sunny sky situation highs will range from near 90.F degrees across the north, to around 97.F and even approaching 100.F near the Iowa Boarder and River Valley cities in the southeast. Urban Rochester area will have highs around 96.F with the airport probably staying around 92.F Tomorrow will again be more about the humidity becuase heat index values no matter where you are will will likely be around 100 to 105.F
Chances Thunderstorms Wednesday
Wednesday a cold front moving south could spark a few thunderstorms across the area during the afternoon and evening hours. These storms will probably be fairly isolated in nature. Some of the storms that do get going will have the chance to become severe but the chances is not high for this. The best chance for storms will occur across the north and not all areas will see rain.
