WHAT HAS CHANGED

A Heat Advisory has been issued for the entire area from 8 PM Friday through 8 PM Saturday.

KEY MESSAGES

1) High confidence of extreme heat through Friday daytime hours. Chance for thunderstorms in the late afternoon and evening.

2) Heat Advisory issued for the 4th of July holiday. Scattered thunderstorms are expected on the 4th.

AVIATION /11Z FRIDAY THROUGH TUESDAY/

Any residual fog should burn off shortly after sunrise, leading to another mostly sunny day. A few cu are possible during the afternoon and some high level cirrus will slowly drift across the region. Winds along and north of the I-70 corridor (KDAY, KLCK, KCMH) will be around 8-10 knots out of the southwest today, while areas south (KCVG, KLUK, KILN) should remain around 5 knots, also out of the southwest.

The big question comes this evening, when we have a chance for thunderstorms to move into the region. For now, have included a PROB30 around 00z and later for northern TAF sites, where residual storms from a complex up near the Great Lakes are forecast to move into. However, confidence on whether storms hold together is low at the moment and will likely come into clearer focus throughout the day today. Should storms fire, they'll be more pop-ip in nature with heavy rain, lightning, and gusty winds.

Outside of any thunderstorms, expect winds to go calm again overnight and patchy fog to develop.

OUTLOOK...Thunderstorms are possible at times through Tuesday.
