Hail in Oklahoma, May 5, 2019

What happened
The episode as NWS AMA wrote it up.
A weak disturbance in broad west northwest flow in the mid and upper levels of the atmosphere, strong daytime heating and attendant atmospheric instability, sufficient moisture, a developing dryline, and moderate wind shear aided in development of several severe storms on May 5th. Most of the Severe Weather occurred in Texas on this day, but there was one report of nickel sized hail 1 mile NW of Kerrick, TX just across the TX/OK state line in Cimarron County.

Area forecast discussion, May 5, 2:55 PM CST, 28 minutes before
Area Forecast Discussion National Weather Service Amarillo TX 355 PM CDT Sun May 5 2019 .SHORT TERM...This Afternoon and Tonight... Showers and thunderstorms are expected to continue to develop across the northwest CWA late this afternoon into this evening. Some isolated showers and thunderstorms will be possible across the southern Texas Panhandle near the Caprock. Local convergence along the Caprock may be enough to initialize thunderstorms. If thunderstorms develop in this area they could become severe with large hail and damaging winds the main threats. If storms can last toward sunset in the southeast Texas Panhandle, then a tornado threat will increase as a low level jet enhances the shear in the lowest layers and also increases the low level moisture which will help to lower the LCL's. Severe thunderstorms will also be possible with the activity that moves across the northern CWA with large hail and damaging winds the main threats. Showers and thunderstorms should be moving out of the area or dissipating toward midnight. Low clouds are then expected to move back across much of the area overnight. 15 && .LONG TERM...Monday through Saturday... Monday sees a transition to southwest flow aloft as the upper closed low moves onshore into southern California. A series of shortwaves will eject out from the main low and bring chances for thunderstorms Monday through Wednesday to the Panhandles. Monday and Tuesday look to have the possibility of large hail and damaging winds from looking at forecast soundings. CAPE could be 2000 to 2500 J/kg on each day. DCAPE around 1000 J/kg could bring winds of 70-80mph. Low level shear on Monday is pretty low, but is over 100 m^2/s^2 on Tuesday. Thus the tornado threat may be more substantial on Tuesday. By Wednesday night, some precip may happen for the north or western Panhandles, but coverage will be limited thanks to being mostly dry slotted as the low opens up to a wave and passes through. Instability will be very low to non-existent so just rain chances for now. The next system is a bit fuzzy between long range models for the end of the week. It is set to start sending out shortwaves ahead of itself, which will bring more chances for rain Thursday into Friday with instability returning on Friday night through Saturday.
