A heat advisory is out for Tuesday and Wednesday.
High humidity will lead to heat index values as high as 109 Tuesday afternoon.
A dryline will move in to western Oklahoma. This means the humidity will drop to as low as 7% out west.
Winds will be strong out of the southwest with gust up to 35 mph. This will mean high to extreme fire danger.
Along the dryline, isolated thunderstorms will try to form. If a storm can develop it would have the potential to produce large hail and damaging winds. Take the heat seriously! Make sure you are staying hydrated and taking breaks if you have to work outdoors.
