(OLNEY/NEWTON) A weak high pressure ridge will control our weather today with a mixture of sunshine and clouds, but a dry sky for this Saturday through Saturday night. After the passage of a weak cold front by early tomorrow morning, we’ll turn a little cooler Sunday, but still dry with eventually some sunshine by tomorrow afternoon. Then a weak short wave trough moves across Illinois, bringing rain and light snow chances for Christmas Eve night and on Christmas Day morning, however most of the precipitation chances are to our north, along or north of a line along Interstate 70. Our attention then turns to a major storm system developing out west of the Rockies, which will gradually make its way to the Upper Midwest / Great Lakes region by next Friday. While the particular track is still uncertain, the weather system could bring heavy amounts of rain with possible thunderstorm activity to our downstate area on Thursday and Friday. Stay tuned for weather updates and monitor a NOAA Weather Alert Radio for more weather information.
