Area forecast discussion, Jul 30, 11:51 PM CDT, 2 hours 9 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 1151 PM CDT SAT JUL 30 2016 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Still some potential for patchy light fog early in the forecast period, otherwise VFR conditions will prevail through the forecast period. Thunderstorms developing from northwest through central KS presently may eventually impact northwest AR or even extreme northeast OK later tonight into Sunday morning. Isolated diurnally driven thunderstorms also possible Sunday afternoon but coverage too low to include in the forecast. && .PREV DISCUSSION... /Issued 846 PM CDT SAT JUL 30 2016/ ..UPDATE... DISCUSSION... Afternoon thunderstorms that developed across southeast Oklahoma today have largely diminished with the loss of daytime heating, and additional development is not expected tonight in that region. Will go with a dry forecast for the rest of the evening, with attention then turning to the MCS potential toward sunrise Sunday morning. Thunderstorm development is expected to occur late this evening and into Sunday morning as the low level jet increases into western and central Kansas. These thunderstorms will approach parts of northeast Oklahoma and eventually northwest Arkansas late tonight and into the early daylight hours tomorrow. Have increased the POPs into the chance category and spread mentionable POPs to the west and south a bit after 09Z. Other weather elements were adjusted for current trends, with no major changes. Updates out soon. PREV DISCUSSION... /Issued 615 PM CDT SAT JUL 30 2016/ AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Isolated thunderstorms across southeast OK will continue for an hour or so after issuance, potentially impacting KMLC through 02z. Otherwise VFR conditions through the period, with some light fog possible late tonight. Complex of storms expected early Sunday morning to the north of the forecast area, may impact parts of far northwest AR around 12z, thus will carry PROB30 -TSRA for XNA/ROG. PREV DISCUSSION... /Issued 357 PM CDT SAT JUL 30 2016/ DISCUSSION... Convection across mainly southeast Oklahoma and northwest Arkansas may continue into the early evening before dissipating. MCS development late tonight and Sunday morning is mainly expected to be north of our area, but the tail end of any complex may brush across northeast Oklahoma and northwest Arkansas. Isolated diurnal convection may also occur Sunday afternoon, but the coverage should be lower than it has been today. The main story over the next week will be the heat. An upper ridge will expand over the center of the country and remain in place through the week. Cannot rule out isolated diurnal convection just about any afternoon, but the coverage will remain too low to mention in the forecast. Some places may approach heat advisory criteria Sunday afternoon, with heat headlines becoming increasingly likely by early in the upcoming week as temperatures creep up towards and eventually to the century mark in some places. The GFS brings a weak cold front into the area next weekend, but the ECMWF holds this front to the north which will maintain the heat through at least next weekend. Stayed close to guidance temperatures the next couple days. TSA Watches/Warnings/Advisories... OK...None. AR...None. && .PRELIMINARY POINT TEMPS/POPS...
