Area forecast discussion, Aug 8, 2:38 AM CDT, 2 hours 10 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 238 AM CDT Tue Aug 8 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today) Issued at 237 AM CDT Tue Aug 8 2023 Of immediate concern is the ongoing severe weather across east central and southeast Oklahoma within the mid level moisture axis and associated with an approaching mid level vort max currently in southwest to south central Oklahoma. Another batch of strong to severe storms is located across northwest and north central Oklahoma in response to another vort max in western Kansas. Storms across far southeast Oklahoma have exhibited supercell structure and likely produced large hail despite high freezing levels. Much like yesterday, these thunderstorms should persist past sunrise with an overall decrease in coverage toward midday as the mid level forcing shifts east of the area. Locally heavy rainfall could become an issue, especially in parts of far southeast Oklahoma where training could occur. High temperatures today should be below normal once again, with forecast values nearer to those offered by the short term blend as opposed to the NBM. && .LONG TERM... (Tonight through Monday) Issued at 237 AM CDT Tue Aug 8 2023 Potential for additional thunderstorm development will exist early Wednesday morning focused mainly across northeast Oklahoma and into far northwest Arkansas, but it is less certain than the last couple of nights have been. This development will result from an increasing low level jet, with the bulk of the thunderstorms likely to be north of Oklahoma and Arkansas borders. Wednesday features the best potential for organized severe weather across parts of far eastern Oklahoma and into Arkansas, in association with a robust upper level system set to move through the Central Plains. Thunderstorms should develop along the cold front - currently forecast to be near the I-44 corridor - late afternoon and into the evening, shifting east of the area by midnight. Regarding the severe weather potential, what happens tonight will play a major role in that given the possibility of residual cloud cover impacting instability and also any lingering boundaries. Large hail, damaging winds and tornadoes look to be a concern at this point. A brief dry period should follow the Wednesday system, with overnight MCS activity increasing once again Thursday night into early Friday, primarily across northeast Oklahoma and into northwest Arkansas. This same region will remain at risk for nightly MCSs through the weekend and into early next week, with the ridge center remaining south in Texas. Temperatures should reach above normal levels late this week and continue through the weekend, with heat advisories or warnings becoming necessary again. While the chance of seeing triple digit ambient temperatures doesn't look likely, the rains we've seen of late could leave us with higher humidity and some nasty heat indices. && .AVIATION... (06Z TAFS) Issued at 1217 AM CDT Tue Aug 8 2023 Another round of TSRA will impact the E OK sites early in the period mainly between 08z-12z with MVFR vsbys in thunder included in TEMPO groups. TSRA axis may miss the NW AR sites, but will include a VCTS mention between 11-13z. KFSM will carry the same VSBY restrictions in two tempo groups between 09z-15z. Once thunder ends, VFR elements will prevail for the remainder of the period at all sites. && .PRELIMINARY POINT TEMPS/POPS...

Storms may be ongoing Tuesday morning across southeast Oklahoma
and western Arkansas, but will diminish in coverage as the
morning progresses. Another complex of storms is expected to
develop Tuesday night across Kansas and move southeast into
northeast Oklahoma and northwest Arkansas late Tuesday night, with
storms continuing into Wednesday morning. Wind will be the
primary severe threat with this complex.
Additional storms may develop Wednesday afternoon and evening along a
frontal boundary that will be moving through the area. However,
coverage and intensity of Wednesday afternoon and evening storms
will be dependent on the evolution and impacts of the previous
storm complex. Beyond Wednesday, isolated to scattered storm
chances remain possible into the upcoming weekend.
