A much warmer and humid weather pattern regime looms this weekend into early next week.
A ridging pattern is to develop across the Southeastern U.S. which will result in a return flow from the south-southwest leading to warmer temperatures and higher humidity levels over the Midwest this weekend and early next week. Forecast calls for our warmest temperatures in over a week and the possibility of seeing our first back to back 90 degree high temperatures Saturday and Sunday. High temperatures Saturday and Sunday will range from the mid 80s to lower 90s.
Included in this warmer weather pattern regime will also be day to day chances for showers and thunderstorms to develop over the region. Thus, cloud and storm coverage will determine if areas in Chicago reach the 90s.
Monday also calls for very warm and humid conditions with 90s a possibility as well. Thunderstorms, some of which could be severe, is expected Monday night ahead of a trailing cold front and upper level trough.
The cold front and associated trough will temper down the temperatures and humidity levels to that of more seasonable levels for the remainder of the week before ridging and a southerly flow regime kicks in bringing more warmth and humidity next weekend and into the second week in July.
