A rather large low- pressure system moves across the Central Plains and into the Midwest Thursday into Friday afternoon with the potential to produce some severe thunderstorms in the intersection between Iowa, Kansas and Missouri and extending down into Northwestern Oklahoma. The main danger with these storms is possible damaging winds and hail, however tornadoes are not of much concern right now due to lack of instability, storm-relative helicity and low level moisture. We will likely see the dry line over the Southern Plains meet and be overrun by the progressing cold front moving along the Central Plains during Thursday evening. The cold front will continue to surge northeast and extends southeastward to eastern Texas producing a long line of showers and thunderstorms along it throughout Friday. The following graphic depicts the composite reflectivity expected Friday afternoon showing you just how far this line of storms extends.
Finally, Champaign-Urbana is nearing 80 degrees yet again! Thursdays early morning low only dips down to 50 °F, while the high is expected to get up 78°F in the afternoon. Clouds will be increased during the morning hours, but will begin clearing in the early afternoon leaving the remainder of the day mostly sunny. It will also be a bit breezier with SSW winds ranging from 9-21 mph. As a cold front cuts across Illinois Friday morning, rain showers will follow behind it. Thus, showers are likely in the early morning hours with rain chances continuing into the afternoon hours. As cold air sets in behind the front Friday afternoon, we will only reach a high of 58°F on Friday with a low dipping down to 40°F by Friday evening. Cloud cover will be mostly cloudy to overcast throughout the day into the evening.
