A complex weather system is slowly moving thru the central and eastern corn belt states this AM. The primary cold front is pushing eastward across Oh today bringing cooler temperatures across a wide range of the midwest. A secondary cold front is pushing southward from a low pressure over northern Mi across eastern Ia and northern Il bringing some very light rain and mist along and just behind this frontal boundary. High pressure is pushing behind this secondary cold front clearing skies which will bring welcome sunshine and dry weather later today and tonight across a large section of the western and central corn belt states. However Friday morning will be be chilly with lows in the mid to upper 30s across part of Wi, eastern Ia and northern Il and 40s elsewhere. Friday's weather will be cool but there will be plenty of sunshine with temperatures in the 60s and 70s. In the western corn belt, thunderstorm chances will return Friday night and persist at intervals into next week, potentially leading to flooding in some areas. Severe weather is unlikely this weekend. In the central corn belt states there will be a chance of showers and thunderstorms through the holiday weekend with the best chances of rain expected Sunday. Though temperatures will be below normal there will be a gradual warming trend. Warm temperatures are forecast for later next week and the first week in June. We watch the sea surface temperatures in the central Pacific in the Nino 3.4 region and have seen the sea surface temperatures turn weakly negative this past week. The NWS seasonal forecast model is showing that the sea surface temperatures in the Nino3.4 region are forecast to slowly continue to warm especially in the late summer and early Fall.
