What's the weather like in Oklahoma this weekend? Expect high temps and possibly a pop-up storm
Finally Friday Forecast!
No major changes are expected in the current pattern over the next several days. A strong mid-level ridge of high pressure is centered over northeastern Oklahoma today and will gradually shift eastward through the weekend. This will result in morning lows in the mid to upper 70s and daytime highs in the upper 90s. 
Mostly sunny conditions will prevail, though a few clouds may develop across parts of eastern Oklahoma this afternoon and through the weekend.
The combination of low-level moisture and local evapotranspiration will support heat index values ranging from 105 to near 112 degrees.
The National Weather Service has issued a heat advisory from noon until at least 8:00 p.m. for most of northeastern Oklahoma. 
A few counties may briefly reach heat warning criteria this afternoon, with heat index values exceeding 110 degrees. South winds will provide minor relief, ranging from 10 to near 15 mph.
Any Pop-Up Storms This Weekend?
The probability of a pop-up shower or thunderstorm this weekend remains largely confined to extreme eastern Oklahoma and western Arkansas, with most of the area staying dry.
We’ll continue to keep a mention for a pop-up, isolated storm both this afternoon and Saturday afternoon, mostly across southeastern Oklahoma into northwestern Arkansas. 
There is a slightly higher probability of a pop-up thunderstorm Sunday afternoon along and east of Highways 69 and 75, though chances for the entire period remain below 10% for any given location.
What About Next Week?
Early next week, the strong ridge of high pressure will retrograde westward and become centered over the Four Corners region as a strong upper-level trough develops across the Great Lakes and into the Yukon region of Canada.
This will support a northerly flow from the Midwest into the Central and Southern Plains by Tuesday, potentially lasting into the latter half of next week.
Monday and Tuesday will still feature highs in the mid to upper 90s, with heat index values ranging from 103 to near 107 degrees. 
Local heat advisories will likely be needed as the ridge shifts westward and upper-level flow becomes more favorable.
A few showers or storms may approach the area Tuesday night into Wednesday, possibly accompanied by a weak boundary from the Mid-Missouri Valley region into part of northern OK by Wednesday morning and early afternoon.
This pattern change could bring slightly cooler weather than currently forecast, but we’ll keep highs in the lower 90s for Wednesday and Thursday for this forecast update.
