.DAY ONE...TODAY AND TONIGHT

Hot and humid conditions will increase today, with heat index
levels this afternoon and early evening ranging from 95 to 100.
Some spots may exceed 100 heat index this afternoon, and a heat
advisory may be required. In any case, those outside working
should plan on frequent breaks and make sure to drink plenty of
water.

The Storm Prediction Center is forecasting a Slight risk for
severe storms in areas north of Interstate 80 through tonight,
and a marginal risk farther south. While a warm layer of air above
the ground may prevent storms from forming today and tonight,
there is a chance that storms over Minnesota build south towards
the area this afternoon and evening. If that happens, then these
storms will bring the threat of damaging winds and heavy rainfall.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

There will be a chance for more thunderstorms on Monday and
Monday evening. Strong to severe thunderstorms will be possible
with damaging wind and large hail the primary threats. Locally
heavy rainfall and flash flooding in areas that experience
repeated thunderstorms will also be a concern. The Storm
Prediction Center has a marginal risk of severe thunderstorms
across most of the Outlook Area for Monday.

There will be periodic chances for thunderstorms from Tuesday
night through Friday, but severe weather potential appears low at
this time.

Very warm and humid conditions will continue on Monday with heat
index readings ranging from the mid 90s to near 100 degrees.
