TULSA - Happy Thursday!
It was a scenic but sweaty run along the Arkansas river this morning. It felt more like spring than autumn with the ramped up humidity and the temperatures to match.
I don't see any reason why this will change tonight or tomorrow. The steamy airmass won't change so we should see another night time low near 70 and another daytime high near 90 on Friday.
There are some changes in the rainfall timeline as we head into the weekend. Earlier in the week, I talked about how the rain could arrive in time for Friday Night Lights (High School Football). Well, now it looks like the arrival of the cold front is delayed just long enough for us to get the games in and to further limit any severe weather threat across NE Oklahoma.
Like last week, the computer models differed on how much rain we could see. The often reliable North American Model or NAM was out to lunch last week while the Global Forecasting System model or GFS was a lot closer to rainfall timing and amounts.
So with that in mind, I am going with the second model and leaning toward a later arrival of the rain, and think we should get some nice downpours, no severe weather, and a wet start to Saturday.
So here is what I'm thinking.
1. Rain does start til mid night or later Friday night into Saturday.
2. Saturday morning is damp but drying off by lunch.
3. Rainfall amounts will range from a few hundredths of an inch to an inch across Green Country.
If you look at the rainfall amounts graphic that the band of rain appears to weaken east of Tulsa, so eastern portions of Green country could less rain. If you live west of Highway 75, then you could get more than a half inch of rainfall. I will go over these details on 2 News Works for tonight at 5, 6 & 10 p.m.
Here is the timeline of the rain.
Starts: Around Midnight
Heaviest: Middle of the night
Tapers: Between 6 & 7 a.m.
Stops: Around 8 a.m.
The rest of Saturday is mostly cloudy & cool with highs in the 60s.
