Area Forecast Discussion National Weather Service Tulsa OK 619 PM CDT Mon Apr 20 2020 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Scattered thunderstorms will continue through around 02z, possibly impacting NW AR TAFs through that time. Severe storm likely impacting KROG at issuance time with at lest brief IFR conditions. Impacts at other sites less certain. Once storms die off VFR conditions will prevail, except for some fog potential across SE OK and NW AR late tonight. && .PREV DISCUSSION... /Issued 144 PM CDT Mon Apr 20 2020/ DISCUSSION... Scattered thunderstorm are expected to develop later this afternoon across northeast Oklahoma and northwest Arkansas as a weak surface trof moves into the region. The cap has pretty well eroded across this region with surface based cape expected to be between 1500 to 2000 j/kg late this afternoon. Some of these storms could become strong to severe with hail to the size of quarters and wind gusts to around 60 mph possible. This activity is expected to diminish this evening as is moves into a more stable environment and the surface boundary weakens considerably. The next chance of showers and thunderstorms will come Tuesday night through Wednesday night. Strong isentropic lift is forecast to develop across eastern Oklahoma and western Arkansas Tuesday night as the low level jet strengthens in advance of a mid-level low moving out of the Southern Rockies into the Plains. The mid-level low will move across Oklahoma Wednesday into Wednesday night before exiting to the east Thursday morning. The associated surface low is set track across southern Oklahoma during this time. The best chances for surface based thunderstorms will be Wednesday afternoon and evening across southeast Oklahoma and west-central Arkansas. This is where the greatest potential for severe thunderstorms will exist with large hail and gusty winds the main concern. However, the elevated storms across northeast Oklahoma and northwest Arkansas will also have the potential to be severe with large hail the main concern. Heavy rain will also be a concern during this time with most of the area seeing 1 to 2 inches of rain with locally higher amounts possible. After a brief respite, the chances of showers and thunderstorms return Thursday night into Friday as a cold front sweeps through the region. && .PRELIMINARY POINT TEMPS/POPS...
