.SHORT TERM...
(The rest of today )
Issued at 1050 AM CDT Wed May 14 2025

Surface low pressure was centered over south central Kansas into
northern Oklahoma as of mid morning. From the surface low a warm
front extended southeast into southeast Oklahoma and western
Arkansas. Also from the low was a north south oriented dryline
across central Oklahoma. Ahead/northeast of the warm front,
dewpoints of mid 60s to near 70 deg were common, while lower 70
deg dewpoints were reported across far southeast Oklahoma between
the front and the dryline. Behind the dryline, more westerly winds
and dewpoints of 50s to lower 60s were observed.

Through this afternoon, the warm front is progged to lift
northeast through northwest Arkansas with the movement of the
surface low. Meanwhile, the dryline is forecast to reach into
eastern Oklahoma this afternoon. The placement of these features
along with associated dewpoints will help determine just how warm
afternoon temperatures climb today. Forecast high temps of upper
80s in northwest Arkansas to low/mid 90s in southeast
Oklahoma and the western portions of the CWA still seem
reasonable. The higher dewpoints mid/late afternoon should be in
northwest Arkansas, while the western portion of the CWA should
be west of the dryline. The warmer temps over eastern Oklahoma
will help create heat index values in the low 90s as well.
However, with the lower dewpoints over these locations, this
should keep the heat index from reaching its full potential.
Either way, this heat after a period of below seasonal average
temperatures could create heat stress for those
working/exercising outdoors this afternoon.

For the morning update, have added minor adjustments to max temps
and the hourly temp/dewpoint trends based on the movement of the
boundaries and latest observations. The rest of the forecast seems
to be handling well at this time.

.LONG TERM...
(Tonight through Tuesday)
Issued at 353 AM CDT Wed May 14 2025

A weak frontal boundary will move across the area late tonight and
Thursday. A few high based showers may develop Thursday morning
from southeast Oklahoma into western Arkansas, with isolated
thunderstorm development possible Thursday afternoon and evening
near the weakening frontal boundary in this same general area. Any
storm that develops will have the potential to become strong to
severe.

Another weak frontal boundary pushes into the area Friday and
weakens, and may be the focus for a few thunderstorms Friday
afternoon and evening mainly southeast of Interstate 44. Again any
storm that forms may become strong to severe.

Showers and thunderstorms are expected to become more numerous
over the weekend into early next week as several shortwaves move
across the area ahead of the main upper trough to the west. Severe
storm potential will increase during this time period, especially
Sunday and Monday, with Monday afternoon and night perhaps seeing
the greatest potential for organized and more widespread severe
weather as the main upper trough approaches.

.AVIATION...
(12Z TAFS)
Issued at 613 AM CDT Wed May 14 2025

VFR conditions are expected to prevail through the forecast
period, though an area of low clouds expanding across central AR
may build close enough to the NW AR sites for an inclusion of a
SCT low layer early in the period. Light SE winds will increase
and become more SW this afternoon.
