Once again, near triple digit readings with maximum humidity will produce oppressive heat indices or feel-like afternoon temperatures over 113°.

An EXCESSIVE HEAT WARNING continues until 7pm Monday Evening for the entire WBRZ viewing area. This means that feels-like temperatures are expected to be over 113° for more than 2 hours. In an excessive heat warning you should use caution outdoors—do not over exert, take frequent breaks and wear light, loose-fitting clothing. Ample hydration is very important. Check on anyone without access to air-conditioning as warm nights don’t afford the body a chance to cool down. Lastly, don’t forget about pets—have a cool place and water for them too!


Today and tonight: Sunshine will warm morning temperatures into the 90s by 11am with a high temperature near 100° by mid-afternoon. The record high for today’s date is 102° and some spots could get close to that. Humidity will remain very high combining with those near record high air temperatures to produce sensible temperatures or heat indices between 113° - 118°. Like Saturday and Sunday, a late day shower may kick up thanks to the very high instability created by the heat, but don’t count on that. Tonight will be quiet and very muggy with a low struggling to fall below 80°.

Looking ahead: Alas, a cold front will move into the region on Tuesday. The front will aid the development of scattered showers and thunderstorms on Tuesday Afternoon, after temperatures top out in the upper 90s. This should be spell good rain chances for most. Thanks to the high heat and humidity, there is ample energy to turn any showers and storms strong with gusty winds and frequent lightning being the main threats. Beyond the front, temperatures and humidity will be knocked back from the dangerous, record levels but will remain high. Wednesday through Friday we look for highs in the mid 90s and lows in the mid 70s—at least a little closer to average. Shower chances will be isolated each afternoon.


Forecast Discussion: The upper ridge responsible for the near-record warmth since Saturday is beginning a slow push to the west. As it budges Tuesday, the door opens for a weak summer front to slide into the area. This “cold” front will be the forcing mechanism (recently lacking) to push our very unstable, hot and humid surface air upward creating numerous showers and thunderstorms. With that high instability noted, any thunderstorms will be capable of turning strong or severe with gusty winds and frequent lightning. Wednesday through Friday, with the front stalled on the coast, it along with marine breezes will keep some isolated showers around the area. While still above average, temperatures will feel a little better than the previous several days.
