Area forecast discussion, Jul 16, 3:52 PM CDT, 2 hours 14 minutes before
Area Forecast Discussion National Weather Service Norman OK 352 PM CDT Fri Jul 16 2021 ...New LONG TERM... .SHORT TERM... (This evening through Saturday) Issued at 119 PM CDT Fri Jul 16 2021 With the upper level wave moving off slowly to the east, precipitation has dwindled. However, with a moist and unstable airmass in place and possibly some lingering boundaries, some isolated afternoon convection will still be possible, with the greater chances being across eastern Oklahoma (under the influence of the departing low). Not much change in the environment tomorrow, so expect to see similar low chances for isolated showers and storms (with the better chances in the east). While heat indices don't quite reach heat advisory criteria (looking at heat indices in the upper 90s to just over 100 across much of the area tomorrow afternoon, driven largely by dewpoints in the mid 60s to lower 70s), mostly clear skies and light winds will drive up the wet bulb globe temperature. Heat precautions are recommended. Day && .LONG TERM... (Saturday night through next Thursday) Issued at 329 PM CDT Fri Jul 16 2021 Sunday's weather will, more or less, be a continuation of Saturday's weather, as the overall atmospheric layout over the southern Plains will remain basically unchanged. The only meaningful difference might be surface boundaries, if significant convection occurs on Saturday or Saturday night. A shortwave trough aloft will move through the southwestern Midwest and southern Plains Sunday night through Monday night. It will bring support for increasing convection to the region during that time period. Its effects, including residual surface boundaries, will linger for a few days, before large-scale ridging aloft clamps off most of the precipitation by the middle to late part of next week. As the ridge aloft expands from the central Rockies/Great Basin into the central Plains, it will also tend to raise temperatures both aloft and at the surface. This should eventually bring an end to the nearly month-long stretch of near- or below-average daily maximum temperatures that has been occurring over much of our forecast area. Deterministic medium-range models show various small disturbances within the larger ridge next week, but at this point, those are more for entertainment purposes than they are for meaningful forecasts, given the large amount of variability between models and model runs. CmS && .AVIATION... (18Z TAFS) Issued at 1222 PM CDT Fri Jul 16 2021 Generally VFR conditions and light winds will prevail. A few isolated storms will continue to be possible (mainly during the afternoon periods), but coverage and probability are too low to mention at any TAF site. Day && .UPPER AIR... Issued at 1226 AM CDT Fri Jul 16 2021 No upper air flights are scheduled for today. && .PRELIMINARY POINT TEMPS/POPS...

However, there is some uncertainty this afternoon and tonight due to impacts from the last night and this morning's activity. Locally heavy rain will be a concern. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... .Heat... An increase in temperatures and dew point temperatures will lead to heat index values of 100 to 105 degrees fahrenheit on Saturday. Heat indices, combined with mostly sunny skies and light winds, may lead to heat exhaustion or heat stroke. Limit strenuous outdoor activities, find shade, and stay hydrated. .Thunderstorms... Thunderstorm chances will continue across at least part of the area through the middle of next week. While some strong thunderstorms are possible, the potential for organized severe weather is low.
