Strong jetstream in the west could bring severe weather

Today
....but not for us!  As we enjoy nothing but sunshine and warm temperatures the rest of this week, a powerhouse of a jetstream has moved into the southwest pulling down very cold temperatures.  Winds within that part of the jestream range anywhere between 110 - 130 kts (125 - 150 mph).  In fact, some of the higher elevations in the west could stand to see up to a foot of snow!  With such a strong jetstream in place low pressure has developed at the surface along the eastern Rockies.  This continues to pull in a very warm and windy air mass across the Plains.  With the warmer temperatures and higher dew points, strong to severe thunderstorms will likely develop across Colorado and then move along a dry line that extends into Wyoming.  From there storms will likely move into parts of Nebraska, northern Kansas and southwest South Dakota.  That's where the Storm Prediction Center has currently outlined a slight risk of severe weather.

Friday
As the the cold front moves further east into the Midwest and southern Plains the threat for severe storms will continue Friday.  The front may actually have a hard time moving any further to the east as high pressure holds firm in the Ohio River Valley.  This would cause any storms, should they develop to our west, to move to the northeast.
