Excessive Heat Continues in the Southwest on Monday

A cold front will bring relief to the Pacific Northwest on Monday, but the Southwest will see above average temperatures again. Excessive Heat Warnings are in effect for many locations through Monday evening. The hottest temperatures will be in the desert as daytime high temperatures may exceed 115 degrees. Read More >

There will be a risk for rain and storms today as an upper level trough slides southward through North and Central TX. The best rain chances will be across western portions of North TX and across Central TX. Widespread severe weather is unlikely, but a few storms may contain gusty winds and heavy rain. Afternoon max temperatures will climb into the 80s.
Low storm chances will linger tonight across portions of western North TX and across Central TX. Overnight low temperatures should be comfortable with readings in the 60s and 70s.
After the nice break from the heat over the weekend, temperatures will warm up again into the 90s this week. There will be low chances of showers and thunderstorms across parts of North and Central Texas this week. Highs will be in the lower 90s and lows will be in the low-to-upper 70s.
Here's an early look at the forecast for the 4th of July Weekend (Saturday through Tuesday). There is a chance for isolated to scattered rain Friday night and Saturday, but then an upper level ridge will move across the region, potentially keeping Sunday through Tuesday dry. Temperatures will be warm/hot in the mid 90s to around 100 degrees.
