Tied Down
@denverpilot I never figured Denver for that kind of weather. Oklahoma or Kansas maybe, but not Denver.
Ahhh. It’s where it starts and then rolls east.
Much of it misses Denver west of I-25 toward the mountains. They’re a bit of a shield for westerly weather.
But the downslope winds and the mixing caused by the big rocks to the west often are part of the trigger for afternoon building when the temp/dewpoint and stability numbers are right.
Once you get out to true eastern CO, you’re into the Great Plains and the storms hammer those folks (Fort Morgan, Sterling, etc) and continue building as they roll east into Nebraska and Kansas long into the night.
Nothing quite like the setup for severe storms they have in Oklahoma though. That stuff gets with it down there. NSSL is parked in the right place for sure.
That night thirnderstorm thing weirded me out when I first spent time further east. Around here it’s so dry that after the storms pop, they’ve sucked all the moisture up and moved it on toward NE and KS and once the sun sets and afternoon heating ends, for most conditions the severe weather is over for the day. Afternoon blow ups, it rolls east, and it’s done.
Out there those things just get bigger and bigger and keep feeding themselves on new moisture and instability and keep rolling through all night long. That... is pretty rare here. We’ll get isolated nastiness at midnight or later but not too often a large line of cells that just keeps marching through after dark. If we get that, it’s usually triggered by an upper level wave moving through.
