TULSA, Okla. -

Our long run of below-normal temperatures is gradually fading away, but we’ve still got more sunshine to enjoy to wrap up the weekend!

Our afternoon highs have been inching up a couple of degrees each day, and we’ll keep that trend going for our Sunday. Once again we’ll have plenty of sunshine and highs inching a bit further into the lower 90s, which is right at normal for this time of year. It’ll be muggy in the mid-late morning hours with a very little cooling breeze, but humidity values will drop off a bit by mid-afternoon, so we shouldn’t have a major heat index factor.

We’ll settle in to pretty much a rinse-and-repeat pattern this week. We should get one more morning Monday with some lows in the 60s, before lows in the lower 70s return for the rest of the week. And afternoons will be pretty steady-state as well, with highs in the lower to mid-90s and plenty of sunshine.

Humidity levels will finally, and unfortunately, rise by Tuesday into Wednesday, partially in response to two tropical systems, Marco and Laura, that are headed for the Gulf coast. Rain chances look to hold off until mid-late week, and heat index values may climb back near 100 by Wednesday afternoon.

The current tracks of both Marco and Laura are setting up for landfall somewhere near the Louisiana coast, first Marco on Monday and then Laura behind it Wednesday night or very early Thursday. The same areas of the Louisiana coast could end up getting hit by two tropical storms or hurricanes in the span of 48-72 hours!

The center of circulation of Marco will dissipate south of Oklahoma, and the center of circulation of Laura should track a bit to our east, but their remnants may send enough tropical moisture our way for showers and thunderstorms by Thursday into Friday. There’s still a lot of uncertainty in those exact tracks, so we’ll keep you updated on that as details become more clear.

I hope you have a great Sunday, Green Country! You can follow me on Twitter @StephenNehrenz as well as my Facebook page Meteorologist Stephen Nehrenz to stay up to date with the very latest.
