FORECAST

HOT & HUMID TODAY

Heat and humidity will be the big story. After a bout of morning clouds, temperatures will reach into the low-90s. With thick humidity, that’ll translate to a feels-like temperature of near 100° during the afternoon hours. Also, expect hazy skies due to smoke filtering in from Mexico.

A stray storm this evening cannot be ruled out (10%). Should a storm develop, severe weather would be possible.

RAIN CHANCES AHEAD

Storm chances increase slightly tomorrow (20%). Once again, severe weather is possible.

By Wednesday a frontal boundary will push into the area, raising rain chances even more (30%). It will also cool us down into the 80s for Wednesday and Thursday.

A storm system, plus a frontal boundary will bring our best shot at rain on Friday (40%). Scattered showers and storms are possible.

Once the front passes by on Friday, cooler and drier weather will filter in over the weekend. Highs in the 70s and lows in the 50s will make for beautiful weather!
