TULSA, OKLA — **HEAT ADVISORY FOR MUCH OF EASTERN OKLAHOMA FROM NOON UNTIL 7 PM WEDNESDAY**

A stalled front across Kansas will keep a very slight storm chance in far northwest parts of our forecast area. Most areas, even north of Tulsa within the viewing area will stay dry.

The heat will continue Wednesday through Saturday as the high pressure ridge keeps its grip over our region. Morning lows will run in the 70s with afternoon highs in the upper 90s to around 100°. Daily heat index values will climb above 100°. Winds will remain southerly all week, but become lighter in the coming days. A few isolated pop-up storms may occur each day, but most of us will stay dry.

The weather pattern should begin to change this weekend as a disturbance in the jet stream moves closer to Oklahoma. This will bring the storm track farther south and increase rain and thunderstorm chances into Sunday. This cold front will usher in a cool-down for Monday (80s for highs), but data is warming us back up through mid next week and delaying the more refreshing cool down until later next week.
