The up and down temperature swing this week will reach its peak this weekend as an area of low pressure currently off the coast of California spins into the Midwest by Saturday afternoon. A weak cool front that will come through Thursday night will lift back north as a warm front as gusty southerly winds move in from the south. Ongoing showers and thunderstorms will be likely at the start of Saturday before a possible break during the afternoon. It's during that break temperatures have the potential to warm into the middle 70s if enough sunshine breaks through. The Gulf of Mexico will be wide open for not only the warmth but moisture to lift northward.
Even though it's still five days away our weather computer models have been fairly consistent in the development and placement of the low. The finer details remain to be hammered out as the weekend gets closer but storms are becoming more and more likely for Saturday afternoon. One possible scenario is for storm development along a cold front from Missouri up to Wisconsin and then for that line to move east into Illinois by evening. If you have any plans for this weekend make sure you keep tabs on the forecast, especially for Saturday, as there may be a few stronger storms to deal with by the evening.
