This Hazardous Weather Outlook is for portions of North Central
Illinois...Northeast Illinois and Northwest Indiana.
.DAY ONE...Today and Tonight.
Weather hazards expected...
Limited Thunderstorm Risk...with an associated:
Limited Hail Risk...up to quarter size.
Limited Damaging Wind Risk...up to 60 mph.
Limited Flooding Risk.
DISCUSSION...
Isolated to widely scattered thunderstorms are likely to develop
across parts of northern IL along a cold front this afternoon.
While the coverage of storms is likely to remain low, the threat
exists for some strong storms capable of producing locally damaging
wind gusts and potentially an instance or two of marginally severe
hail. This activity is expected to wane with sunset early this
evening.
Additional thunderstorms are possible across northern IL after
midnight tonight. While severe weather is not expected with this
activity, heavy rainfall would be likely to accompany these storms.
A localized flash flood threat could thus develop across parts of
northern IL late tonight, especially if numerous storms move over
the same area.
.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
Wednesday...
Limited Severe Thunderstorm Risk.
Elevated Flooding Risk.
Thursday through Monday...
Limited Thunderstorm Risk at times.
DISCUSSION...
Slow-moving heavy rain producing showers and thunderstorms
will continue the threat of flash flooding into Wednesday
afternoon.
Another period of severe weather is also possible on
Wednesday, especially for locations south of I-80 in the
afternoon.
Intermittent thunderstorm chances will linger through the
remainder of the week and into the weekend.
.SPOTTER INFORMATION STATEMENT...
Spotters may be needed this afternoon.
GENERAL STORM MOTION OF THE DAY:
