This Hazardous Weather Outlook is for portions of North Central
Illinois...Northeast Illinois and Northwest Indiana.

.DAY ONE...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.

DISCUSSION...

Thunderstorms may move into northern Illinois from Wisconsin
overnight, though there is fairly low confidence on the timing and
intensity of the thunderstorms if and when this occurs. Should the
thunderstorms maintain enough strength, there may be isolated
instances of severe weather along and north of Interstates 88 and
290. If any severe thunderstorms occur, the main threats would be
wind and hail, along with a threat for locally heavy downpours.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.

Wednesday...
  Elevated Severe Thunderstorm Risk south of Interstate 80.
  Limited Flooding Risk south of Interstate 80.
Thursday and Friday...
  Limited Thunderstorm Risk.

DISCUSSION:

Additional thunderstorms are forecast on Wednesday as a weak cold
front sags south. Some of these may be severe, with a threat for
damaging winds and large hail, along with producing heavy
downpours and possibly an isolated flooding risk. The highest
confidence in occurrence and scattered coverage of thunderstorms
is south of I-80 during the afternoon. If thunderstorms can form
in the late morning through early afternoon farther north, the
isolated severe risk could extend as far north as the Interstate
90 corridor in northern Illinois.

.SPOTTER INFORMATION STATEMENT...

  Spotter activation is not anticipated due to the later night risk.

GENERAL STORM MOTION OF THE DAY:

  Moving toward the east to possibly southeast at 20 to 30 mph.
