As we head into the work week another very strong upper level low will dig into the central and Northern Plains. So my forecast last week was not all together correct as I failed to see the stronger ridge in the east. So we're heading into another split flow where a piece of energy gets stuck underneath the main jet stream. Here is the latest forecasted 500mb level for the exact time I showed you in the last post.
You can notice the lack of support from the northern jet by the time we get into tomorrow evening. This will leave the upper level low to stall and spin across portions of the Central Plains. This will first cause a strong cold front to plow south into the warm and moist air over the Southern Plains. So severe weather is a possibility for portions of Texas, Oklahoma and western Arkansas today. Here is the latest outlook from the SPC.
Temperatures will plunge behind this front to below normal high for several days. I'll have another update on how cool temperatures will be this week here later this afternoon. Plus take a look as I might be just a week off from the Cold Canadian push of air down into the East.
