TULSA, Okla. -

Muggy weather returns on Wednesday along with a few passing showers or storms later this afternoon.

Highs will reach the upper 80s to lower 90s, but heat index values will near 100. We’re tracking a powerful hurricane this morning, plus the potential for active weather this weekend into early next week as a front nears northern Oklahoma.

A few showers, or bands of showers will be possible later on Wednesday moving from the southeast to northwest. This moisture is mostly leftover “Marco” moisture. Any impacts from Hurricane Laura will arrive later Thursday and quickly exit late Thursday evening into early Friday morning.

The track of Laura continues to be southeast of our immediate area. The highest chance for rain from Laura, including heavy rainfall will be located across far southeastern OK Thursday evening. We must keep some probabilities near the metro just in case this system slides more west than anticipated.

There will be a sharp gradient or cut-off between rain and no rain, and the metro could easily remain dry. Gusty winds are also likely to develop across far southeastern Oklahoma later Thursday evening with 20 to 35 mph winds possible. Low level tropical moisture is already surging northward this morning and muggy weather is likely now through Thursday before drier air arrives Friday allowing for a rather toasty afternoon.

Low level moisture will quickly return Saturday evening before a weak boundary brings a chance for storms Saturday night into Sunday across northern OK and southern Kansas. Another front arrives early next week with thunderstorm chances. The cool-down behind this 2nd boundary is not nearly as robust on Wednesday compared to the past three days.

Locations along the southeastern Texas and southern Louisiana coastal region are preparing for a major hurricane. The official forecast has continued from previous but may still require additional adjustments over the next 24 hours or so.

Our forecast may change Thursday and depends exactly on the track of the system. If the track is more west, we’ll have higher chances in the metro. If the track remains as we see now, our chances will continue to be near 30% or less for Tulsa with likely categories across far southeastern OK, where heavy rainfall will be possible.

The system should quickly accelerate away from central Arkansas Friday morning with a temporary intrusion of dry air across most of Oklahoma. This dry air will heat with Friday afternoon highs reaching the mid-90s along with winds changing from the north to southwest by afternoon.

The weekend boundary nears northern OK Saturday evening before stalling and lift northward Sunday. A few storms will remain possible during this period with chances from Tulsa to the north.

Thanks for reading the Wednesday morning weather discussion or blog.

Have a super great day!
