NWS Norman, OK wrote its last area forecast discussion before the first event at May 24, 5:34 AM CST, 2 hours 16 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Norman OK 634 AM CDT Fri May 24 2019 .AVIATION... 24/12Z TAFs. Will keep forecast primarily VFR outside of TSRA. Greatest TSRA coverage expected from around KCSM up to KPNC. Current activity expected to decrease in coverage and intensity through the morning and then redevelop/intensify after 20Z. Where activity is most persistent and widespread will be dependent on where outflow boundary resides this afternoon. Currently, expected near the mentioned terminals. Gusty south winds will continue most areas through the period, with strong wind gusts near storms. && .PREV DISCUSSION... /issued 430 AM CDT Fri May 24 2019/ DISCUSSION... Slight weakening of mid-upper level flow associated with neutral/rising heights, and less of a veering profile expected to reduce overall threat for high end severe weather potential next few days. However, plenty of low level moisture and instability will yield organized severe weather from day to day into early next week. How far east effective outflow from current thunderstorm activity progresses will have huge impact on convective development later today. Model guidance divided on eastward extent of convection, and given strength of mid-level cap, it may be hard for convection to progress much farther east than SPS-OKC-SWO line until this evening and tonight with aid of low level jet. With the potential for additional heavy rain through the day and into tonight, Flood Watch was expanded slightly and extended through 12Z Saturday morning. Possibly more organized late Saturday north and west of CWA, with evolution of MCS across northern into central Oklahoma late Saturday night. Again, without much in the way of larger scale forcing, models are again in disagreement on location and duration of thunderstorm activity. Pronounced s/wv trough progd to approach the Southern Plains from northern Mexico Sunday/Sunday night. This should result in stronger shear and potential for higher end severe, primarily north and west of the body of Oklahoma. Main upper low forecast to progress through central portions of the country Tuesday and expected to bring the potential for more in the way of significant severe weather to the region. Currently, most guidance would suggest that this threat would be over the eastern half of Oklahoma, ahead of dryline/pac cold front, with drier air and mid-level ridging bring chances of thunderstorms to an end for a couple of days. This will be short lived as another western trough develops, influencing frontal boundary to advance back north over the region and bring thunderstorm chances back by Friday into the weekend. && .PRELIMINARY POINT TEMPS/POPS...
