Finally. It appears the mid-level ridge will expand today and Saturday across the state. After a few isolated showers or storms skirt across part of northern Oklahoma this morning, the ridge should shut things down for a while. This should keep the storm chances away from northeastern Oklahoma for the next few days and bring the heat and humidity back to the headlines. But the ridge will move eastward Sunday and should eventually be positioned across the southeastern to Mid Atlantic of the U.S while several disturbances rotate around the western periphery next week. This will result in more cloud cover and additional scattered showers and storms across part of the state. This process may begin Sunday with a slight chance for a few showers or storms across southeastern Oklahoma while spreading better chances into central and eastern Oklahoma Monday through at least Wednesday. Our forecast will be a compromise between the overall wet looking GFS and the mostly not as wet EURO. Stronger westerlies aloft should be positioned mostly to our north for next week. The severe weather threats currently look minimal. A sub-tropical mid-level low may also be arriving out of the Gulf region later next week that may enhance some precip chances somewhere across the southern plains next Friday into next weekend. This probably stays south of our area of influence but its impossible to know with any confidence at this point in the forecast cycle.
Temperatures this morning will remain quite warm with humid weather expected area wide. Local dew points are currently in the upper 60s to lower 70s. Residual moisture from yesterday’s storms across eastern Oklahoma may also result in rather sticky conditions thorough the day as highs climb into the lower to mid-90s. South winds will increase from 10 to 20 mph later today. Temps this weekend should not change too much. Lows will remain in the lower to mid-70s along with highs Saturday in the mid-90s. Heat index values today and tomorrow may be nearing the 103 to 105 range. Sunday highs will drop a few degrees with highs in the lower 90s. Monday through Wednesday will feature lows in the lower to mid-70s with highs in the mid to upper 80s dependent upon the impacts of cloud cover and rain chances.
Thanks for reading the Friday morning weather discussion and blog.
