DISCUSSION
Issued at 229 AM CDT Sat Jul 11 2026

In the upper lvls, a stout region of high pressure will be positioned over the Four Corners region of the CONUS and northwesterly to northerly flow will be present over the state of Arkansas. Into the workweek, the center of the upper lvl high pressure become elongated and fixates over the Northern Plains region of the CONUS. An upper lvl low pressure center will actually retrograde back westward during the middle portion of the workweek influenced by the upper lvl high planted across the Northern Plains into the Mid-West region of the CONUS. Into the later portion of the workweek, an upper lvl high pressure center begins to develop over Southern Plains region of the CONUS.

At the sfc, a stationary boundary across southern Missouri will begin to push southward slowly as a cold front during the afternoon/evening timeframe on Saturday. It is the parameter space along and ahead of this feature across northern and central Arkansas which will set the table for the potential of severe weather. Latest CAMS portray a parameter space with moderate instability and near- zero shear; additionally, 0-3 km lapse rates above 9 C/km and DCAPE values in the range of 1,000 J/kg to 1,300 J/kg will present an environment suggestive of damaging wind gusts associated with thunderstorm development. A few instances of severe hail will be possible and CAMS have lengthened the duration of this event (in tandem with high PW values of 1.7-2.0 inches) which may lead to multiple rounds of rain and storms training over the same locations which would present a threat for flash flooding.

Into Sunday afternoon, the cold front will push into southern Arkansas and be making a run toward the Arkansas/Louisiana border. Latest CAMS show additional development across the southern portion of the state, but this parameter space will not be as primed for severe weather as the activity from Saturday (today). However, damaging wind gusts will be a primary concern in storms that do become severe.

The cold front will stall south of Arkansas as a stationary front by early into the workweek and remain through the mid-workweek and keep POP chances decent across the state for isolated rain and storms; however, widespread activity is not anticipated and POP chances will diminish later into the week as the stationary boundary moves away from the state and a surface high pressure center moves into the region.

Expect VFR conditions across the majority of the state of Arkansas between the forecast period of early Sunday morning and early Monday morning. The remnants of rain and storms continue to impact parts of central and southern Arkansas at the beginning of the period. VCTS has been left within FM groups to outline this concern. However, the overall trend of development across the state early Sunday morning is downward. VSBY at the northern terminals of KHRO and KBPK may lower into MVFR flight category; however most sites will experience VSBY and CIGS which remain in VFR flight category over the forecast period.
