The approach of a weather system nearing our area will result in more clouds on Saturday.
Hazy skies are likely due to the influence of some smoke from Canadian wildfires that arrived earlier this week and the presence of some upper tropospheric dust from the Sarhan dust layer. This is expected to keep temperatures slightly cooler than recent days, with afternoon highs reaching into the upper 80s Saturday.
A weak upper-level low will move from the ArkLaTex region into western Arkansas within the next 24 hours. This system will bring a few showers or storms into southern and far eastern Oklahoma on Saturday. Most data indicate this precipitation will remain east of the Tulsa Metro, but we’ll continue to mention the possibility for the metro in case the system slides slightly more west than anticipated.
By early Sunday morning, this wave will move eastward, and a mid-level ridge of high pressure will extend from the western United States into the Southern Plains. This marks the start of a prolonged period of excessive heat and humidity expected to last through most of the next week.
The core of this ridge may stay slightly away from our area, but its influence will result in very hot conditions. The combination of increasing low-level moisture along with local evapotranspiration rates will cause heat index values to range from 105 to 110 Monday and from 108 to 115 Tuesday through Thursday. The ridge may flatten and slide southeast next Friday allowing a northwest upper flow next weekend. This would be favorable for another heat reduction and some scattered storms.
