Another warm and sunny afternoon is expected across most of eastern Oklahoma with highs in the mid-90s.
There could be a few small showers later this afternoon along the OK-Arkansas state line region, but chances are extremely low. Tropical moisture will be increasing soon across eastern Oklahoma as hurricane Laura moves closer to the southeast Texas and southern Louisiana coastal region.
Marco is weakening rapidly across southern Louisiana and southeast Texas this morning, but tropical moisture will be surging northwest over the next 24 hours and a few bands of showers or storms may move from the ArkLaTex into part of eastern Oklahoma Wednesday.
I will keep a low chance regarding the metro Wednesday with slightly higher chances across extreme east-central and southeastern sections of the state. Highs will reach the upper 80s to lower 90s Wednesday with some heat index values in the mid-90s.
Thursday’s forecast continues to be focused on the eventual track of Hurricane Laura. This system will be in a favorable atmosphere for rapid intensification as it approaches southern Louisiana or southeastern Texas late Wednesday night into Thursday morning.
This storm track could continue to change some, especially later today as the storm departs Cuba and enters deeper and warmer Gulf waters. Based on what we know this morning about the storm, higher probabilities for rainfall will occur along and east of Highway 69, with the highest chances across far southeastern OK and western Arkansas state line region. This places the metro on the far western edge of rain chances and will be represented by only a 30% chance.
This system will also rapidly accelerate away from the state Thursday night as it moves more northward in latitude and is influenced by stronger winds aloft. Friday most of the state will quickly be on the departing side of the system with southwest winds, compressing air and highs reaching the mid to upper-90s.
This weekend a front is expected to reach southern Kansas into northern Oklahoma Saturday evening or Sunday morning bringing a chance for a few storms near this feature. This front is expected to stall before lifting northward Sunday evening or Monday morning before moving back with a stronger southward push by the middle of next week with additional storm chances. Cooler air may also arrive for the middle of next week.
Laura remains the wild card. Additional changes to our Thursday and Friday forecast will remain possible.
Thanks for reading the Tuesday morning weather discussion and blog.
Have a super great day!
