A Week of 2 Seasons Coming Up....

A very warm pattern is setting up for northern Illinois through Thursday with temperatures reaching the 70's Tuesday, Wednesday, and Thursday.  In fact, it is even possible that 80 degrees could be reached on Tuesday, or especially Wednesday, if there is enough sunshine.  A strong cold front will bring an end to the warm temperatures with frontal passage on Thursday night.  Canadian air will follow in behind the cold front on Friday dropping high temperatures back into the low 50's.  On Friday and Saturday, with the core of the cold ridge of high pressure well to our west over the plains, a chilly breeze from Canada with keep high temperatures in the mid  to upper 40's on Friday, and only in the middle 40's on Saturday.

There is still a very great need to replenish the shortage of moisture developed during the ongoing drought.  So, what are the chances of getting some good rainfall this week?   A front will stall out just to our northwest on Monday as low pressure develops on the front over the central plains, and moves toward the northeast.  A strong fetch of moisture will be feeding northward out of the Gulf of Mexico northward into the Stateline.  There is a slight chance of some showers, and possibly a thunderstorm developing late on Sunday night.  It will be cloudy on Monday, and showers will be likely.  Thunderstorms are also possible.  It will be cloudy, warm and muggy on Monday night with a good chance of more showers and thunderstorms.  With all the moisture in the area, there may be some patchy fog.  Scattered showers and thunderstorms may linger through the morning hours on Tuesday.  There will be a good chance of showers and thunderstorms again on Thursday and Thursday night with the passage of a strong cold front.  Early estimates for rainfall totals this coming week are around one inch.  Caution is advised, through, because sometimes this computer generated estimates are way off the mark.
