$$What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 30, 12:36 AM CDT, 23 minutes earlier.
Area forecast discussion, Apr 30, 12:36 AM CDT, 23 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 1236 AM CDT Sat Apr 30 2022 ...New AVIATION... .SHORT TERM... (The rest of tonight) Issued at 746 PM CDT Fri Apr 29 2022 ...SEVERE WEATHER REMAINS LIKELY OVERNIGHT... Cold front, currently surging into far northwest Oklahoma this evening, will overtake dry line and move into northeast Oklahoma by late evening. Line of storms are still expected along front with severe weather likely, especially near the Oklahoma/Kansas line. Moderate instability, coupled with 50 kt deep layer shear and cold temperatures aloft (-15 deg C), will support hail at least to the size of golf balls and damaging winds. Also can not rule out an isolated tornado or two as 0-1km shear increases into the +40 kt range in low level jet axis. The severe threat will begin to decrease as convective line moves south of I-44 with a weakening trend as atmosphere begins to stabilize. Overall forecast looks on track but will continue to tweak hourly grids given latest trends. && .LONG TERM... (Tomorrow through Friday) Issued at 206 PM CDT Fri Apr 29 2022 Aside from lingering shower/storm potential across far south and east Saturday morning, the rest of the day will be quiet with northwest winds and drier air. Dry conditions will prevail through most of Sunday as well before another stout upper system promotes a northward moving boundary back across the area Sunday night into Monday. This scenario should offer more widespread showers and storms Sunday night with a locally heavy rain threat. By Monday, depending on eventual location of warm front and degree of airmass recovery in wake of early precip, severe potential will return to at least parts of the forecast area. Consensus remains for Tuesday to be another "down" day before yet another system approaches mid week, with similar progression of cold front/warm front. By this time, model consensus regarding the evolution of the upper levels becomes considerably less, but the bottom line is potential for more severe weather and heavy rainfall will continue through the later part of next week. && .AVIATION... (06Z TAFS) Issued at 1232 AM CDT Sat Apr 30 2022 TSRA along a cold front moving into NE OK will impact all sites between 06z-12z, with a period of MVFR vsbys/cigs. Gusty south winds will continue ahead of the front, with winds becoming westerly once the front passes. Behind the front, a period of MVFR cigs may linger for a few hours across the AR sites, otherwise VFR elements will prevail for the remainder of the period. && .PRELIMINARY POINT TEMPS/POPS...
