Area Forecast Discussion...UPDATED National Weather Service Norman OK 1022 PM CDT Mon Jun 26 2017 .AVIATION...27/06Z TAF ISSUANCE... Overall, VFR conditions are expected to prevail through the period. Scattered thunderstorms will continue to move into north central Oklahoma, likely impacting KPNC before the 06z window opens. Additional scattered thunderstorms are possible overnight, but confidence in timing and location are too low to place in any TAF site. Sites that may be impacted would be in northern Oklahoma, through the early morning hours. Winds will generally be out of the south, increasing tomorrow, late in the morning through the afternoon. Gusts over 20 kts are possible across western Oklahoma. Scattered to broken mid-level clouds will persist, increasing in coverage through tomorrow afternoon. Kurtz && .PREV DISCUSSION... /issued 929 PM CDT Mon Jun 26 2017/ UPDATE... Increased the chance of showers/storms across far northeast portions of north central Oklahoma. DISCUSSION... Scattered thunderstorms continue across southeast/south central Kansas this evening. These thunderstorms may clip far northeast portions of north central Oklahoma--including parts of Kay, Noble and perhaps Payne counties later this evening/tonight. Therefore, opted to increase the chance of showers/storms--especially across northeast Kay County--for this evening/tonight. One mitigating factor is environmental conditions downstream are not favorable downstream as elevated instability is limited. Therefore, would expect severe weather risk to be minimal. There is lower confidence for thunderstorms elsewhere; however, weak ascent within the embedded northwest flow and any remnant outflow boundaries may result in a few isolated showers/storms across parts of north central/northwest Oklahoma later tonight. Mahale PREV DISCUSSION... /issued 543 PM CDT Mon Jun 26 2017/ AVIATION...27/00Z TAF ISSUANCE... VFR conditions are expected to prevail through the period. Scattered to broken mid-level ceilings will persist through the evening hours, dissipating overnight. Winds will generally be out of the south and southeast, light, with calm to variable conditions also possible. Winds will increase late Tuesday morning through the afternoon, remaining out the south. At the same time, scattered to broken cumulus is expected to develop, similar to today. Kurtz PREV DISCUSSION... /issued 326 PM CDT Mon Jun 26 2017/ DISCUSSION... Moderate instability covers much of the western half of Oklahoma and western north Texas. Without low-level convergence and without significant vertical wind shear, if any storms form, they will not be able to organize. The HRRRX shows isolated storms through the evening over this area, and satellite imagery shows a large field of cumulus clouds. However, the latest of the satellite images does not show any significant cumulus growth, so it seems that low or very low PoPs are justified for this evening. As the surface high moves away, the pressure gradient tightens tomorrow, which will strengthen the southerly low-level flow. This, in turn, will help nudge temperatures upward over the next several days...along with dewpoint temperatures. Strong capping should prevent any significant precipitation until a cold front moves into northern Oklahoma on Friday. Much higher chances for rain will arrive with this front, and will continue through the weekend. Since the front will not move much during the weekend, it is possible that some locations may receive quite substantial rainfall amounts. CmS && .PRELIMINARY POINT TEMPS/POPS...
