.DISCUSSION...
Issued at 119 AM CDT Sat Jul 19 2025

Heat and humidity will be the main theme throughout the forecast
period. Each day has only slight changes synoptically leading to a
more persistence forecast with trends hotter or cooler. Tomorrow
looks to be another hot day with high dewpoints above 75F along
I-40 and I-57 corridors. Due to Heat Index values at 110F or above
in most counties in that area from our NBM model, we upgraded that
region to an Extreme Heat Warning with a Heat Advisory around the
area. Southern Arkansas will see cloud coverage and scattered
showers from a stalled boundary and tropical remnant moisture.
This will lower temperatures, but add a flooding risk with the
efficiency of these storms as 1-1.5" of rainfall an hour is
possible. If storms can stall or train over the same area it won`t
take much to get to 2-3" and reach flash flood guidance. Sunday
has less cloud and rain chances, so it is likely another Heat
Advisory will be issues, but unlikely a Extreme Heat Warning will
be in place as dewpoints will drop slightly.

The remnant tropical system over TX will stall the building of the
upper level high through the weekend, but it will begin to build
into our region quickly early next week. By Tuesday-Wednesday the
GFS is showing a 500mb high of 595-597 right over Arkansas. This
will be the hottest period of the year. Most guidance has the all
valley areas seeing at or above 100F with heat index values above
110F. The upper high starts to shift east with weak troughing
moving into the area from the west starting Friday, which may
increase our PoP chances and decrease the oppressive heat
slightly. Models do tend to move these highs a little to quickly,
so we will have to watch trends to see if this breakdown of the
ridge actually happens as we move into next week.
