Upper-level ridge of high pressure will intensify slightly today and this will add 1-2 degrees to the already very hot afternoon temperatures. Afternoon temperatures of 104-106 in the excessive heat warning area can be expected with heat index values of 108-110. Elsewhere afternoon temperatures in the 100-103 range will be common with heat index values of 107-110. College Station recorded 106 yesterday which tied its 71-year-old daily record.
An upper-level ridge of high pressure is building yet again over the southern plains, this time centered over OK and N TX where surface air temperatures will reach 108-113 degrees over the next few days. Locally SE TX is sitting at the base of the ridge and we will “only” see actual air temperatures in the low 100’s however heat index values will reach 107-112 during the afternoon hours which is good enough for another heat advisory that starts tomorrow and will likely last much of the week.
