Dangerous heat for Arkansas this week

We are expecting dangerous heat to build throughout the duration of the week. It will be imperative, especially as we near the middle of the week, that any location lacking electricity and/or access to air conditioning will be at a greater risk for heat-related illnesses.

High Temperatures and dangerous heat index values will increase for the duration of the week across Arkansas.

• The most concerning days for heat-related illnesses will be on Wednesday, Thursday, and Friday where both the air temperature and dewpoint temperature will increase.

• The reason will be a warm front lifting through the state on Wednesday leaving a more moist airmass across the state in its wake.

More rounds of showers and thunderstorms for Arkansas into Friday; weather briefing from the National Weather Service in Little Rock

A front will be nearly stationary across southern Arkansas through at least Friday. Scattered to numerous showers and thunderstorms will surround the front Wednesday and again Friday.

Storms that become severe will be capable of producing very large hail and damaging wind.

A new cold front will arrive from the Plains late Saturday into Sunday. Another round of strong to severe thunderstorms will likely accompany the front.

Late in the weekend and early next week, precipitation will become more spotty and it will heat up. Heat index values will likely exceed 100 degrees, mainly from Little Rock southward.

Today and Tonight...

A Heat Advisory is in effect today for all of the Four State
Region. Temperatures will again climb into the mid and upper 90s
this afternoon across the area, and when combined with the
humidity, will result in heat indices ranging from 105 to 110
degrees. In addition, isolated to widely scattered showers and
thunderstorms will develop today over portions of East Texas and
North Louisiana, before diminishing by sunset.

Friday through Wednesday...

Very hot, humid, and mostly dry conditions will continue across
the region Friday through Sunday, as an upper level ridge of high
pressure begins to shift southeast into the area. This will result
in the hottest temperatures so far this summer, and when combined
with the humidity, will produce heat indices that will near or
exceed 105 degrees each day. However, a weak cool front will shift
south into the region late Sunday, which will focus an increase
in showers and thunderstorms over the area late Sunday through
Tuesday. The increased cloud cover and rain near and behind the
front will also contribute to slightly cooler temperatures Monday
through midweek.
