How did the eclipse affect the temperatures across North Texas? A weather station in Roanoke, which records weather data every minute, experienced a 2.2 degree drop during the course of the eclipse. Incoming solar radiation peaked at 770 W/m^2 and bottomed out at 183 W/m^2 at 1:08. Locations closer to the total eclipse experienced more substantial temperature changes; such as Casper, WY, where the temperature before the eclipse was 73 degrees, and dropped to 66 at eclipse totality.
It will be mostly sunny and hot across the region on Tuesday with highs in the mid to upper 90s. Heat index values will range from 97 to 105 degrees.
An Ozone Action day will be in effect on Tuesday for portions of North Texas. Conditions will be favorable for elevated levels of ozone pollution. You can prevent ozone pollution by: sharing a ride, walking, riding a bicycle, and keeping your vehicle properly tuned.
A cold front will move into the region Tuesday evening and overnight, bringing better chances for showers and storms to North Texas. The highest chances will be near and north of I-20. Any storms will be capable of producing locally heavy rainfall and strong winds during this period.
Temperatures will be slightly cooler with highs in the upper 80s to low 90s. An unsettled weather pattern will bring rain chances for the remainder of the week, and possibly into early next week. Stay tuned for updates!
There will be a threat for unsettled weather this weekend as a surface frontal boundary stalls. The lift along the front, coupled with lift from a few disturbances rippling through the northwest flow and increased tropical moisture may set the stage for rounds of rain. Some of this rain could be potentially heavy. Check back to the forecast for details as they become available!
