The National Weather Service has issued an excessive heat watch for most of the area. Heat indices (the combination of the air temperature and the dew point) are expected to exceed 100°, and could be as high as 110°. The watch begins for some western counties on Wednesday and the rest of the area on Thursday. The entire watch will end on Saturday.
Actual air temperatures will top out in the mid 90s, which isn’t too far off from what we’ve seen in the past couple of years. However, the National Weather Service hasn’t issued an excessive heat watch since July 2011.
Though it will feel like 100+° during the afternoon on Thursday, Friday and Saturday, air temperatures have not been that warm since 2013. The chart below shows the last time the temperature was 100° or warmer:
Cooler air (with highs in the 80s) is expected to track in on Sunday.
