 The surge of humidity back into the area by tomorrow morning. By tomorrow afternoon, a hotter day than today with highs right around 100 degrees and with more humidity in the air, that 100 degrees will feel a lot closer to 110, which is why the National Weather Service will have an excessive heat warning that goes into effect at 11 a.m. lasting till about 8 p.m. We're also tracking the chance that a few afternoon showers and storms, some of which could be strong to severe.
