833 FXUS64 KTSA 070903 AFDTSA Area Forecast Discussion National Weather Service Tulsa OK 403 AM CDT Sat Aug 7 2021 .DISCUSSION... Hot and humid conditions will be the rule for much of the forecast period, with some minor heat relief possible by Friday or Saturday. Maximum heat index values may touch the magic 105 threshold in a few spots both today and Sunday, with more widespread 105+ heat index values becoming more likely during the Monday through Wednesday timeframe. Will hold off on a heat advisory at this time, and let the day shift monitor temperature and dew point trends today. One big difference from this round of heat as compared to the last one is that southerly winds will be quite breezy this time around, thus WBGT values will remain lower than they were then, keeping the heat stress lower. An upper level system passing to our north will bring a chance of showers and thunderstorms late tonight and Sunday, with the highest chances in northeast Oklahoma and northwest Arkansas. An isolated severe storm or two will be possible Sunday. Shower and storm chances may linger through at least Sunday night across parts of far northeast Oklahoma and far northwest Arkansas as well. Shower and thunderstorm chances will return Wednesday through the end of the week as a frontal boundary approaches from the north. This front will eventually push into and through the area, but it may take it until Friday or Friday night to have any real effect on temperatures. Stayed close to the National Blend of Models forecast. && .PRELIMINARY POINT TEMPS/POPS...
