Temperatures soared to 90 degrees under mostly sunny skies for the first time since July 19th when the mercury hit 93 degrees. Today’s 90 degree high pushes our 2013 90 degree total to seven. Today marked the 6th day in a row with temperatures above 80 in the Rockford area and even though a cold front will push through the region late tonight/early tomorrow morning the streak will continue well into next week and beyond. Current indications from the Climate Prediction Center indicate temperatures across much of the country will be above normal through the end of the month and to wrap up meteorological summer (June – July – August).
A cold front across far northern Wisconsin and southern Minnesota will march southeastward into the North Central Illinois region early Thursday morning. The Storm Prediction Center in Normal, OK has outlooked areas to the north in Wisconsin for a slight risk of severe weather. The primary threat to our north will be damaging wind gusts (> 60mph), large hail (> 1”), heavy downpours, and vivid lightning. Storm should increase in coverage in the Rockford Metro area during the overnight hours Thursday and into the early morning hours. Up to a ½ inch of rain may fall, with some locally heavier amounts in the areas that get hit with the strong storms. A second round of storms may form tomorrow earlier in the afternoon ending by the evening rush hour. Current indications point to this being the best and last chance of any significant rainfall until well into next week, worsening the drought in our area.
Temperatures tomorrow pull back to the lower 80s. The comfortable humidity and modestly warm temperatures will only last through Saturday. Current indications are that a hot dome of warm and humid air will take hold over much of the Midwest and Great Lakes starting on Sunday and lasting well into next week. Temperatures near and exceeding 90 degrees look possible starting on Sunday and lasting well into the middle of next week with little rainfall, if any falling over much of North Central Illinois where farmers badly need the rain.
