Friday Morning Update

Good morning.  We're tracking another system today with rain chances across eastern OK.  The trajectory will keep most of the rain with embedded thunderstorms located along and east of the Tulsa area.   We're still keeping high probability for the Tulsa metro, but we may be very close to the back edge (western edge) of the precip shield for this event.  


The model data supports moderate rainfall along the highway 69-75 corridor.  Data continues to suggest rainfall in the amounts from .30 to nearing 1 inch in some locations.  Some elevated instability is a possibility and this means a rumble of thunder or two will be possible across southeastern OK with this system and the higher chance for thunderstorms may reside south of the I-40 corridor.   

The rain is developing this morning to our south and will move northeast during the next few hours.  RAP data and others support the system exiting the immediate area around 1pm to 2pm and then exiting far eastern OK into western Arkansas by the 3pm to 4pm period as a boundary pushes across eastern OK.  Some partial clearing is likely behind the system this afternoon to the west with the remainder of the clouds exiting the state later tonight.   

Temperatures this afternoon will continue to climb.  A warm front is currently located near the Red River and will lift northeast during the day.  This will bring temps up into the lower 50s near Tulsa and the lower 6s across south-central OK this afternoon with south winds in the 10 to 20 mph range.  

Saturday morning we'll start in the lower 30s with highs in the mid to upper 50s.  A mid-level ridge across the Pacific Northwest and a trough in the eastern U.S. will bring a northwesterly flow aloft across the southern and central plains for most of the incoming week.  Sunday a weak boundary will clear the state late Sunday evening but temps will actually warm during the afternoon with highs in the lower to even mid-60s.  Some minor temperature changes will be likely next week with several frontal boundaries moving across the state, but no major air mass changes will occur.  

A fast moving system Monday could provide some brief showers across far NE OK but at this point, the chance will remain off the big 7 day planner.  

The official high in Tulsa yesterday was 37 recorded at 4:53pm.

The normal daily average high is 47 and low is 27. 

Daily records include a high of 76 from 1990 and a low of -5 from 1977.

You'll find me on Facebook and Twitter. 

Thanks for reading the Friday Morning Weather discussion and blog.  

Have a super great day.
