Dry and hot weather is now the main factor in conditions across
the Four State Region as tropical influences wane for now. This is
due to ongoing easterly surface flow that will also wane in
intensity through the next 12 hours as surface ridging shifts
westward and overhead. A warming trend will begin to take effect
as a result with temperature maximums/minimums in the
mid-90s/mid-70s. Dew points in the upper 60s/lower 70s will not
help with overnight heat relief. /16/

(Saturday through next Wednesday)

The hottest temperatures of the year are on the way to the Four
State Region this weekend into early next week. The surface ridge
axis responsible for this will continue to intensify across the
Southern Great Plains, maintaining southerly flow by Sunday. Long-
range guidance still indicates higher chances of triple-digit
temperatures on Sunday and Monday with probabilities above 15
percent (statistically significant, some areas higher than 30
percent), especially along and north of the I-20 corridor. After
the middle of next week, this ridge axis will break down further,
opening the door for more diurnal convection that`s typical for
this time of the year. While remaining well above average,
temperature maximums will also retreat from triple-digit
territory, but not by much in the upper 90s. Temperature minimums
in the mid-to-upper 70s will not provide much in the way of heat
relief overnight.

Heat hazard products are likely late this weekend into early next
week. Adequate precautions and awareness are encouraged ahead of
time against the elevated potential for heat illnesses. For this
weekend, this includes (and is not limited to) altering outdoor
plans, taking frequent breaks if you must be outside, checking the
backseat of your vehicle, and knowing the signs and symptoms of
heat exhaustion and heat stroke. /16/
