100 Degree Streak Could End Today
FORT WORTH (CBS 11 NEWS) – After what may go in the record books as the “warmest morning ever” at DFW with the low hitting only 86 degrees, it’s hard to imagine that our dangerous heat story has temporarily taken a back seat to small pockets of rain and a record heat streak in jeopardy.
But our 24 days of back-to-back 100s could come to an end today as the upper level disturbance in the skies over North Texas produces a perforated layer of clouds roughly 8,000 feet thick in some areas. We could find ourselves nowhere near 100 degrees by day’s end.
It will take a while to erode the clouds as the sun heats the layer from above and the limited sunshine making it to the ground slows down today’s temperature climb. A layer of clouds can knock a good 10-15 degrees off from the forecast high depending on thickness. We could find ourselves topping out closer to 95 than the 105 I put in the forecast this morning.
That said, the cloud deck is thinned out enough over the Metroplex that temperatures stand a decent chance at 100-101 while areas along the Red River will battle the cloud deck most of the day and likely top out in the 90s. This is also the area getting the spotty showers. As the showers push from north to south, they are dissipating and only a stray shower is likely for metro areas of Dallas, Fort Worth and the Mid-cities.
The Heat Goes On
If today’s high does not make 100 degrees, it would be a shame because the overall weather story will continue to be the oppressive, dangerous heat. A Heat Advisory continues through 8 PM on Wednesday with forecast heat indices 105-110. Today we may fall short of the criteria, but we are certainly back to it Wednesday and possibly Thursday.
I’ve attached a picture of the visible satellite image and an updated North Texas forecast. If the cloud deck holds along the Red River areas, highs there may only reach 88-92 degrees.
