376 FXUS64 KOUN 211918 AFDOUN Area Forecast Discussion National Weather Service Norman OK 218 PM CDT Tue Aug 21 2018 .DISCUSSION... The next three mornings will bring chances for rain and thunder to northern Oklahoma. This is because of upslope flow into moistening mid-levels over the Colorado High plains on the northern reaches of the strong upper high. Afternoon thunderstorms are expected during the preceding afternoons and prevailing weak westerly flow is expected to bring the storms/rain into southern Kansas and part of northern Oklahoma. Recent forecast trends have been to intensify the upper ridge more quickly over Oklahoma which would diminish rain chances farther south of the northern Oklahoma border areas. At present, the expectation is for scattered thunderstorms lasting a bit beyond sunrise Wednesday through Friday mornings. Because of the northward tendency of the upper ridge, subsequent forecasts will likely adjust coverage or placement of pops, but areas south of I-40 will have little chance for rain through the weekend as the heat intensifies. South winds will begin to gust from Thursday as humidities drop to around 20 percent Friday and Saturday over parts of northern Texas and southwestern Oklahoma. Meanwhile, increased moisture over central and eastern Oklahoma will take heat index values over 100 by the end of the week. && .PRELIMINARY POINT TEMPS/POPS...
