Storm Coverage Increases Wednesday Night

Heavy rain producing thunderstorms are expected once again Wednesday night with rainfall totals possibly nearing one inch by Thursday morning.

Skies are quiet now but severe storms, with several tornado warnings, have been ongoing across eastern Iowa Wednesday evening.  I do not anticipate those storms to impact northern Illinois, however, storm coverage will increase over west-central Illinois between 9pm and 10pm and will move into northern Illinois between 11pm and 4am Thursday morning.

More of the focus for severe weather will remain to the west and southwest through the night, but a few stronger storms can't be ruled out with wind and hail being the primary concerns.  Heavy rain will be our biggest threat overnight with another inch of rain possibly falling by Thursday morning.

Scattered showers will move out by morning following the passage of low pressure mid-morning Thursday.  Following the low a cold front will move through during the afternoon and evening.  This will bring another chance for showers and thunderstorms before dry air moves in Thursday night.  This will lead to a mostly dry, and warm, day on Friday.
