The humidity dropped this afternoon.. finally. After a week of dewpoints in the upper 60’s and low 70’s we had drier air move in from the northeast. Dewpoints dropped to the low 60’s; not dry air by any definition but at least some relief in the heat index calculation. Yesterday it was “Sweat it Out”. Today its more “Muggy”. The National Weather Service dropped its Heat Advisory for north Texas early this afternoon.
But remember this. The temperatures you hear on-air are taken in the shade. If you are working (or playing) IN THE SUN you need to add about 15° to the temperature. At 5pm the DFW temperature was 96°, the heat index at 98°. But if you were standing in the sun the heat index is 113°. This would meet the Heat Advisory Threshold of the National Weather Service.
Our Weather Watchers reported a range of temperatures from 99° in Everman (Tarrant County) to 92° in Commerce (Hunt County)
We expect a hotter day tomorrow (and this weekend). Here is the hour-by-hour outlook. By lunchtime it’ll already be in the low 90’s. We are expecting our third 100° day of the year.
We’ll likely hit triple-digit numbers through Sunday. Keep that in mind if you are doing yard work or just out playing with the kids:
I’m sure you see the good news. It comes out of Canada. We see that it’s below freezing just north of Hudson Bay.
The weather pattern is changing back to what it looked like during our last cool spell (a week ago highs were only in the 70’s for three days in a row). The cool air is settling in over the Great Lakes. That low pressure system over the lakes will drive cooler air into north Texas in the form of two cold fronts:

This break in the heat will also mean a break in the dry weather. We have rain chances again! They peak on Wednesday of next week.
