Marine Weather and Tide Forecast for Lead Hill, AR

DISCUSSION
Issued at 240 AM CDT Thu Jun 18 2026

Mosaic reflectivity early Thurs AM depicted a broken line of storms moving ESEwrd acrs Srn MO. Objective sfc analysis indicated a cdfrnt oriented SWwrd fm a Great Lakes sfc low, slowly approaching the Ozark Plateau. Thru the day today, this frnt wl slowly move Swrd into the FA, w/ Nrly winds ushering in drier air.

Aftn SBCAPE values of 2000-3000 J/kg and NWrly effective shear of 20 to 30 kts wl support some organized storm potential acrs the Nrn half of AR Thurs aftn to evng. Pt fcst soundings indicate some drier air aloft, w/ modest low-level theta-E differences, and 3CAPE values near 80-100 J/kg, alluding to mainly a damaging wind threat w/ any pulsing convective activity.

Into Fri, the aforementioned frnt is progged to continue slowly moving Swrd, stalling over Srn AR by Fri evng, continuing to serve as the focus for PoPs, and an attendant, but low severe threat thru the day. Behind the frnt, cooler and less humid condns wl be seen by the Nrn two-thirds of the state.

Thru the weekend, mean H500 NWrly flow wl persist acrs the Midwest region, w/ broad sfc high pressure lingering over the Mid-South vcty. A Wrly component to H500 flow wl promote lee sfc cyclonic flow acrs the Srn Plains, w/ Srly sfc flow quickly resuming over the state by Sat. As sfc cyclonic flow becomes more organized and maneuvers Ewrd, a broad warm sector is progged to extend over much of the Srn Plains and into the Ozark Plateau. There is still a moderate degree of uncertainty thru this PD, though deterministic guidance continues to suggest a few shortwave troughs maneuvering thru mean NWrly flow, w/ mass fields indicating strong cold pool/MCS activity following the periphery of the aforementioned wrm frnt into Nrn AR Sat and Sun nights. Mon and thru mid-week, H500 NWrly flow wl continue, w/ daily scattered PoP and thunderstorm covg favored acrs the FA.

In addition to severe threats thru the weekend, higher QPF values remain possible thru the latter half of the PD, w/ NBM/WPC guidance continuing to advertise a corridor of two to four inches of rainfall acrs the Wrn half of the FA. Temps thru the PD wl stay near normal values, w/ intermittent bouts of cooler than normal temps behind passing cdfrnts, and limited concerns for hazardous heat condns.

Issued at 620 AM CDT Thu Jun 18 2026

Mixed VFR/MVFR condns were noted acrs the FA Thurs mrng, w/ sat imgry depicting lower cloud cover moving over Cntrl to Srn AR.
Expect MVFR CIGs to persist at area terminals thru the later morning hours, before improving to VFR levels by this afternoon. A cdfrnt wl be moving thru the region fm Nrn AR this aftn, w/ VCSH possible along the frnt. Have kept precip mentions for now, though confidence remains low on covg at the moment. Ahead and behind the frnt, Nrly winds wl ensue over the FA as the frnt moves into Cntrl AR.
