Well there was a MCS....

But not quite what I was thinking. The MCS developed in the evening, just as my original prediction had said, in western Nebraska (and eastern Wyoming) and moved east-southeast through southern Nebraska and northern Kansas before pulling south across central Kansas towards northeastern Oklahoma. So, the system did develop and tracked pretty much where I was thinking (except I was thinking more up near Kansas City than northeastern Oklahoma). However, the system did not have any severe weather associated with it except for a brief period back in Wyoming and western Nebraska.


Why did it not have the severe weather associated it? Because of a front sitting in the central Gulf of Mexico. As Bernie Rayno said on Point-Counter-Point yesterday, the dewpoints were just not high enough because the inflow from the Gulf was being cut off. Which is exactly what happened. Instead of low 60s dewpoints in Nebraska they were in the mid to upper 50s. This is not the environment you would expect for a wind event. Actually, 70 degree dewpoints are much more supportive. Thus, the system wasn't severe, but it was there.


And the system yesterday will help increase the potential for the coming weekend as a front shifts south through the plains. Already in areas where storms have developed the last few days, storms have redeveloped (in Montana, Wyoming, and South Dakota). These storms will once again produce an MCS which will move through Nebraska likely into Kansas. Will the system be severe? Not quite likely yet. However Friday into Saturday looks like a much better environment with dewpoints slowly rising.

Also, check out this map of rainfall from just yesterday in Florida. Yes, 6+ inches will easily be reached...and that was only from one 24 hour period.
