.UPDATE...
Issued at 958 PM CDT Mon Jul 15 2024

majority of the ArkLaTex, allowing low temperatures to drop well
into the mid to upper 70s by daybreak. A few areas of fog are
possible in sheltered zones torwards dawn, particularly around
the Toledo Bend country. Ingested the afternoon and evening
temperatures and dew point obs and interpolated through to 12Z.

.SHORT TERM...
(This evening through Tuesday Night)
Issued at 247 PM CDT Mon Jul 15 2024

Hazardous heat will continue across the Four State Region through
the next 36 hours with little in the way of relief expected from
any precipitation that may form. This is due to surface ridging
that will linger across the southeast US and the Mississippi River
into Texas, maintaining light southerly winds and dew points in
the low-to-mid 70s. Temperature maximums will remain in the upper
90s while minimums remain in the mid-to-upper 70s, not much of a
reprieve from daytime heat.

Heat hazard products are likely to be issued through the middle of
this week across the area. Adequate precautions and awareness are
encouraged now against the elevated potential for heat illnesses.
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/

.LONG TERM...
(Wednesday through next Sunday)
Issued at 247 PM CDT Mon Jul 15 2024

Cooler weather will begin to arrive later this week as a less
common summer cold front makes its way into the area. This is due
to a fairly robust surface ridge that will make its way south
from Canada into the Great Plains/Midwest, allowing somewhat more
active northerly flow aloft (and diffluent flow near the Gulf) to
instigate more convection along the frontal boundary as it
eventually stalls near the Gulf Coast. By this weekend, the
convection will become more diurnally driven, producing 1 to 1.5
inches of rainfall in the next week. Overall, this activity will
keep temperature maximums/minimums in the lower 90s/lower 70s,
slightly (and fortunately) below average for this time of the
year. /16/
