...TWO ROUNDS OF HEAVY RAIN EXPECTED BETWEEN NOW AND THE
A cold front will approach Illinois tonight. Along and ahead of
this front we can expect strong to severe thunderstorms. In
addition to the severe weather, very heavy rainfall is expected as
the storms will track repeatedly over the same areas. Widespread
1.5 to almost 2.5 inches of rain can be expected by sunrise
Thursday morning with the heaviest amounts along and near I-55,
which should occur this evening.
Another very moist storm system will move into the region late
Friday and remain in the area through the weekend. Total rain from
Friday evening through Sunday Night across the area is expected to
generally range from 2 to 4 inches across central and southeast
Illinois with the highest amounts of 3 to 4 inches being southeast
of the Illinois river.
The heavy rain falling on saturated soil from tonight`s storms
will produce rapid runoff and a potential for localized flooding,
as well as, river flooding across the region. Stay tuned to a
reliable source of weather information as the weekend approaches
and the potential for flooding becomes clearer.
