Once again we're tracking a few showers and storms across the area this morning. These developed late yesterday evening and persisted overnight across the south-central portion of the state. This area, possibly enhanced by a mesoscale convectively induced vort, has been moving eastward during the overnight hours. Our chances will remain for the next few hours into midday before this activity slides away from the area. Not all locations will receive precip today, but we'll need to keep a decent chance in the forecast for the next few hours. Some of the RAP runs keep this feature across southeastern OK up through the I-40 corridor between now and about noon. We more than likely will be forced to " now-cast" this feature for the morning hours. Afternoon highs top out in the mid to upper 80s with partly to mostly cloudy conditions. There will also be some variance in temperatures across eastern OK due to the presence of this morning system. I wouldn't be shocked to see a 90 or two across central or far northern OK later today.
The weekend will feature warm and muggy conditions with morning lows in the lower 70s and afternoon highs in the lower 90s. An isolated shower or storm will be possible, but the chance looks to be less than 10% for any given location. Some of the model data has developed a few showers or storms for portion of the area this weekend, but I'm still inclined to keep these pops either very low or out of the 7 day planner.
Early next week the pattern is expected to change. Our upper air flow will be from the northwest. This should allow a front to move southward into the state by Tuesday. This boundary will stall across northern Oklahoma for a few days next week keeping the chances for showers and storms in the region with temperatures slightly below the seasonal averages. We may also be in the running for some late night and early morning storm complexes that develop across the central plains to move into part of northeastern OK. We have increased the pops for portions of early next week to reflect this pattern change.
The official high in Tulsa yesterday was 84 recorded at 5:11pm.
The normal daily average high is 89 and the low is 69.
Our daily records include a high of 107 from 1918. The daily record low is 53 from 1976.
You'll find me on Facebook and Twitter.
I'll be discussing the weather on numerous Radio Oklahoma News network affiliates across the state through the morning hours.
You'll also hear our forecast on Tulsa metro radio stations, including KMOD, The Twister, The Beat, and The buzz. These stations are part of Clear Channel Communications.
Thanks for reading the Wednesday Morning weather discussion and blog.
Have a super great and safe day!
