Welcome to summer in Texas for the DXC Technology 600 at Texas Motor Speedway, INDYCAR’s annual trip to the Lone Star State. Things usually heat up on track during this race, but this year the temperatures will too.
On Friday morning, an upper level high pressure ridge is expected to move over the southern plains, with the center of the ridge becoming stationary over eastern New Mexico and western Texas; a weaker, but still prevalent high pressure ridge is expected to set up in the mid-levels. Winds in the lower levels and winds at the surface are expected to be out of the south, bringing warm air off the Gulf of Mexico into the area; the latter of the winds being attributed to a surface low pressure system east of the Rockies. Some stronger gusts are likely as the winds will be from the same direction on Friday. With the mid-level ridge suppressing the heat and moisture off the Gulf, temperatures at the surface will heat up with the heat index values likely exceeding 100 degrees. On Saturday, calmer winds in the low-to-mid levels will trap more heat at the surface, resulting in warmer temperatures than Friday.
