As temperatures fell into the upper 60s to lower 70s during the
early morning hours on Tuesday, dense fog developed and spread
across the Quad State region. Reduction in visibility due to the
fog dropped below one quarter of a mile at many locations. A Dense
Fog advisory was posted overnight and remained in effect until 9
am CDT Tuesday morning. Low clouds and fog continued to persist
over extreme Southern Illinois and parts of West Kentucky into the
late morning hours.
Tuesday morning lows ranged from 66 degrees at Carbondale Illinois
and Owensboro Kentucky, upward to 71 degrees at Paducah Kentucky.
By 3 pm CDT Tuesday, temperatures had risen into the middle 80s near the
Interstate 64 corridor of Southern Illinois to the lower 90s in
West Kentucky and the delta region of Southeast Missouri.
The range in afternoon temperatures was strongly influenced by
cloud cover that came from strong and severe thunderstorms that
developed over Southeast Missouri during the afternoon hours.
Between noon and 1 pm CDT, isolated thunderstorms began to move
into parts of Southeast Missouri. Severe thunderstorm warnings
were issued for Bollinger and Cape Girardeau counties. By 330 pm
CDT, a few reports of dime to baseball size hail were reported by
Emergency managers in the aforementioned Southeast Missouri
The thunderstorms that occurred across the Quad State region
Tuesday afternoon were influenced by the passage of a weather
disturbance rolling southeastward from the upper Midwest. Another
disturbance is forecast to move through the area on Wednesday and
will likely bring another round of thunderstorms to part of the
area, before high pressure builds in from the southwest.
This area of high pressure will become anchored over the middle
and lower Mississippi valleys late this week and into early next
week. The heat and humidity associated with this high pressure
will likely bring the first significant heat wave of the summer to
the Quad State region. Temperatures will likely reach into the
upper 90s to near the century mark, with heat index values between
100 and 110 becoming common place from this Friday through next
