Hazardous Weather Outlook For JO DAVIESS County,IL

420 AM CDT Mon Jun 18 2018

 DAY ONE  TODAY AND TONIGHT

Heat warnings and advisories are in effect for the outlook area
through this afternoon. A combination of high heat and humidity 
will produced dangerous afternoon heat index values of 100 to 105 
degrees. 

Scattered thunderstorms will develop by late afternoon north of
Highway 30, then increase in coverage tonight, especially north of
Interstate 80. Areas north of Highway 30 are favored for 
potential heavy rain and flash flooding. There is a low risk of 
severe storms north of Highway 34, with pockets of damaging wind 
the main threat.

Area rivers are experiencing flooding. Please see the latest 
Flood Statements and Flood Warnings for details.

 DAYS TWO THROUGH SEVEN  TUESDAY THROUGH SUNDAY

Thunderstorms are expected to redevelop on Tuesday and move 
across much of the area through Tuesday evening. Some of these 
storms may become strong to severe with damaging wind the primary 
concern. The Storm Prediction Center has placed most areas along 
and south of the Highway 20 corridor in a marginal risk for severe
weather on Tuesday. Heavy rainfall will also be a threat Tuesday,
possibly producing localized flash flooding and aggravating 
ongoing river flooding.

Although not quite reaching Heat advisory criteria, areas along
and south of the highway 34 corridor in southeast Iowa, northeast
Missouri, and west central Illinois may have heat index readings 
in the mid to upper 90s on Tuesday before storms hit the area and 
cool things down later in the afternoon.

There will be periodic chances for thunderstorms from Wednesday 
through Saturday. The predictability of severe weather for those 
mid to late week days remains low at this time. But additional 
rounds of moderate to heavy rainfall may lead to flooding problems.

Flooding is expected to continue on some area tributary rivers.
Rounds of heavy rainfall may also cause additional river sites to
rise later this week. Please see the latest Flood Statements and 
Flood Warnings for details.

 SPOTTER INFORMATION STATEMENT  

Spotter activation may be needed late this afternoon and tonight,
especially north of Interstate 80.
