This Hazardous Weather Outlook is for portions of southern
Illinois, southwest Indiana, western Kentucky, and southeast
Missouri.

.DAY ONE...This Afternoon and Tonight

Scattered to numerous thunderstorms are expected across southeast
Missouri, as multiple outflow boundaries interact with very hot
and humid air over the region. Although organized severe storms
are not expected, a few storms may briefly pulse up to produce
damaging winds to go along with torrential rainfall and frequent
lightning. These storms may reach just east of the Mississippi
River, possibly impacting adjacent portions of southern Illinois
and west Kentucky. Most of this activity should be done by 5 PM.

Outside of the thunderstorms and their outflows, heat indices over
southeast Missouri, southern Illinois and far west Kentucky will
range from 100 to 105 this afternoon.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Isolated afternoon thunderstorms are forecast for part of
southeast Missouri and southwest Illinois on Monday. These storms
should remain below severe limits.

Heat index values will top out again near 100 degrees mainly
during the afternoon hours on Monday across southeast Missouri
and southern Illinois.

Scattered to numerous thunderstorms are forecast Tuesday through
early Wednesday morning. These thunderstorms are expected to move
slowly southeast in a broken line through the outlook area. Some
of the storms will likely become severe late Tuesday afternoon and
evening, with damaging winds the primary hazard, followed by
isolated large hail. Heavy rain will be a greater hazard during
the evening hours.

The Storm Prediction Center has issued a Slight Risk of Severe
Thunderstorms for Tuesday and Tuesday night, extending from
Benton Illinois and the Land Between the Lakes northeast into
parts of southeast Illinois, southwest Indiana, and the Pennyrile
region of west Kentucky. A Marginal risk of severe thunderstorms
covers the remainder of the outlook area Tuesday and Tuesday
night.

.SPOTTER INFORMATION STATEMENT...

Spotters over southeast Missouri should be prepared for activation
this afternoon. Activation may be requested throughout the area
Tuesday afternoon and evening.
