...DANGEROUS HEAT CONTINUES TODAY AND TOMORROW...
This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.
.DAY ONE...Today and Tonight.
THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Limited.
AREA... Terrain areas of southeast Oklahoma and northwestern Arkansas.
ONSET... Ongoing.
DANGEROUS HEAT.
RISK...Critical.
AREA... Eastern Oklahoma and northwest Arkansas.
ONSET... Ongoing.
AREA AT GREATEST RISK... Northeast Oklahoma and northwest
Arkansas.
DISCUSSION...
Dangerous heat is ongoing across much of eastern Oklahoma and
northwestern Arkansas. Heat indices are currently (as of 4:45 PM)
in the 103 to 112 range. If you are outside this
afternoon/evening, be sure to take heat precautions such as taking
frequent breaks in the AC and drinking plenty of fluids.
A few showers and thunderstorms have bubbled up across portions of
southeast Oklahoma and west-central Arkansas. Where storms occur,
dangerous cloud-to-ground lightning will be likely along with
gusty winds and heavy downpours. These spotty thunderstorms are
also bringing local relief from the heat with locations such as
Clayton, OK cooling down from heat indices well over 100 to 89.
Additional thunderstorm development is possible this afternoon and
evening albeit very isolated. This activity will likely dissipate
quickly as we near sun set.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.
.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY and THURSDAY...Thunderstorm Potential...Dangerous Heat
Potential...Heavy Rain Potential.
FRIDAY and Saturday...Thunderstorm Potential.
SUNDAY and MONDAY...Thunderstorm Potential...Dangerous Heat
Potential.
EXTENDED DISCUSSION...
Hot and humid conditions will continue on Wednesday with several
locations exceeding a heat index of 105 with some nearing 110.
Trends will need to be monitored for a potential Excessive Heat
Warning issuance for tomorrow afternoon. The end of this stretch
of very hot and humid conditions is in sight. A cold front will
begin to move into the northern portions of northeast Oklahoma
and northwest Arkansas late Wednesday into Thursday. The front
will be the main focal point for showers and thunderstorms
beginning Wednesday afternoon and continuing into the weekend.
There is the potential of some stronger storms Wednesday and
especially as we move into Thursday with the main severe threat
being damaging wind gusts. The unsettled pattern through the
weekend will bring the chance for multiple rounds of showers and
storms, especially over northeast OK and northwest AR, as well as
much cooler weather. Rainfall totals through the weekend will
generally be in the 1 to 2 inch range for northeast Oklahoma and
northwest Arkansas with totals decreasing the farther southeast
you go. Locally higher rainfall totals will be possible where
storms train over the same areas.
The potential for elevated heat indices starts to increase by
Sunday and Monday as the influence of the cold front begins to
lessen and the upper level ridge builds back into our region.
