Some Much Need Rain Coming This Weekend

A major weather system is about to impact the Stateline. High pressure is moving east tonight followed by a very strong low pressure system moving toward northern Illinois from the plains states. All of the ingredients seem to be coming together for a heavy rainfall event beginning late tonight and continuing into Saturday. It will be clear this evening but it will cloud over quickly before midnight. Showers will be possible after midnight and possibly an isolated thunderstorm. Late tonight showers and thunderstorms will be likely with locally heavy rainfall possible. The overnight low will be around 43 degrees. Southerly winds will increase overnight eventually tapping gulf moisture. Heavy showers and thunderstorms may continue off and on during the morning on Saturday, and severe thunderstorms are possible late Saturday afternoon into Saturday night. It will be breezy and mild with southwesterly winds gusting to 30 mph pumping the temperature up into the middle 60's.  The low pressure system will still be west of the area on Saturday night, and with the Stateline in the warm sector with more showers and storms, and a mild overnight low around 63 degrees. The low will move east of the area early Sunday morning.  Skies will remain cloudy to mostly cloudy with showers gradually tapering off. It will start off on the mild side with a high in the middle 60's during the early morning, but with the wind switching to the northwest cooler air moving in during the day with drop the temperatures to the middle 50's by late afternoon.  It will be partly cloudy and cooler on Sunday night with weak high pressure following in behind the departing storm system with an overnight low of 42 degrees.  The ridge will be in place across the area on Monday. It will be mostly sunny, nice and seasonal with a high around 64 degrees. That ridge will shift east of the area on Monday night, and the next weather system will approach from the plains on.  This system is not nearly as impressive as the last one, but winds will shift to the south on Monday night and continue southerly on Tuesday warming temperatures to near 70 degrees under partly cloudy skies. Scattered showers will be possible on Tuesday night with the front approaching the northwest corner of Illinois by daybreak on Wednesday. The low overnight will be in the low 50s.  On Wednesday and Wednesday night, the front will slowly creep eastward across the area. With the front nearby, there will be a chance of showers from time to time from Wednesday through early Thursday morning. Thursday will be partly cloudy with a high near 60 degrees. A cool ridge of high pressure will dominate the weather next Friday. Skies will be partly cloudy, and the afternoon high will be close to 60 degrees.
