– Winter Precip; > 75%
All forecasting efforts are focused on the significant and life-threatening winter storm to impact Oklahoma starting tonight and ending Tuesday. Once this system moves by, a quick southern stream shortwave trof will skirt through the area on Thursday/Friday. This system should have no moisture to work with and hence only produce some clouds.
Eastern U.S. longwave trof should keep northerly flow across the region and hence cold temperatures for late February. Another fascinating aspect of this is the 540 line plunging into the Gulf by Friday.
NWS numbers look good and I ran with them, only a few minor modifications. I lowered Monday’s high, even though the low-40s represents the morning temperature. I think it is important to note how cold it will be tomorrow afternoon. I’ll take a hit on that number.by
