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.
