Monday, August 17 Morning Forecast

Weather Talk

FAYETTEVILLE, Ark. (KNWA/KFTA) — Watch the video above for a look at your morning weather for Monday, August 17 from Meteorologist Rick Katzfey.

Scattered to broken cirrus clouds…associated with the remnants of a decayed thunderstorm complex in Kansas and an exiting vort max over North/Central Texas…were common across Eastern Oklahoma and Northwest Arkansas early this morning. Also to the north…was a secondary surface boundary currently moving into Northern Kansas. This boundary and an associated upper level trof axis will be the reinforcing shot of some cooler and drier conditions for much of the week ahead.

For today…ahead of the approaching surface boundary…some pooling of the available moisture could allow for dewpoints to get into the lower 70s across parts of Southeast Oklahoma and also along the boundary as it enters Northeast Oklahoma this afternoon. In response…there is a non-zero potential of a stray shower and or thunderstorm this afternoon before the surface boundary clears the CWA this evening. The greater potential may be in Southeast Oklahoma…though with uncertainty of coverage and storm initiation will keep pops just below mentionable criteria and monitor conditions through the day. Any development that may occur should weaken this evening with the loss of daytime heating.

Behind yesterday`s cold front…afternoon temps today look to again warm into the upper 80s and lower 90s over the CWA. There may be a few locations that could be a degree or so warmer compared to yesterday north of Interstate 40…ahead of the approaching surface boundary. Overall…these conditions should keep afternoon heat index values finally below advisory conditions for Southeast Oklahoma.

Surface boundary is progged to exit this evening with the associated upper level trof axis pushing through overnight tonight. In the wake of these departing features…continued slightly cooler and drier conditions are forecast for the CWA through much of the week…as upper level northerly flow remains common over the Plains with the ridge of high pressure over the Western CONUS. Will continue with a dry forecast and highs in the mid 80s to around 90 degrees for the week. By late week into the weekend…southerly low level flow looks to return to the region as the ridge of high pressure tries to expand back into the Plains. In response…a warming trend could be possible next weekend.
