Alan Crone's Weather Blog: Cooler Fall-Like Temperatures

Good morning.   We're getting ready to move into a more “fall-like" pattern for the next few days.  A cold front has moved across the area this morning and is located to our south.   Northeast winds at 10 mph will help bring slightly cooler air into the area today with highs in the upper 70s north and some lower 80s south.  

Another surge of cooler air will arrive tomorrow with a noticeable cool down into the weekend.   A few rain chances will be nearing part of the state for the next few days but the impact across the eastern third of the state will remain very low.   We’ve had to lower the probability for Saturday quite a bit compared to previous updates.  This morning a few sprinkles took a run at part of north-central OK but these dissipated during the last few hours.

The upper air flow from the northwest to southeast will allow a disturbance to move southeast over the state later tonight and early Thursday morning.   Some data suggest a few showers in a narrow zone along the I-35 corridor region.   I will include these pops in mention form only for the Tulsa metro and keep the “real rain” for locations around I-35 westward for Thursday morning.  

Thursday morning lows in the lower 50s will be followed by highs around 73-77 across eastern OK along with northeast winds at 10 to 18 mph by afternoon.   We'll have a sun-cloud mixture across the area by midday to afternoon. 

The noticeable surge of cooler air will arrive Friday into Saturday with morning lows in the upper 40s and highs in the upper 60s and lower 70s over the eastern OK region.   Friday night late into Saturday a disturbance is expected to move across the central plains states and will help to generate some showers across northern OK.  But this morning’s data has continued the trend of taking the main lift north of the region.   While some showers may occur, the overall chance has been lowered compared to yesterday’s forecast for the period.   

Temperatures Saturday should start around 50 for the low and stay in the upper 60s north and some lower 70s south.     Sunday morning supports some upper 40s followed by highs in the around 70. 

Next week should feature a minor warm-up with highs back into the upper 70s Monday and Tuesday before a stronger looking system arrives midweek.   

Thanks for reading the Wednesday morning weather discussion and blog. 

Have a super great day!
