Interesting day here on the Front Range of CO (and points north/east). Today is my son's 12th birthday, so I have a secret hope that he'll be able to see his first tornado.
Forecast attention is confined to the Palmer Divide. Highly moist conditions are blowing on SE sfc winds at the moment into the Urban Corridor. As of this writing (18:37z), sfc obs show 83/53 in Denver with even deeper Theta-E moving in as the day moves on. A sfc low currently over DEN should intensify with attendant increasing sfc winds out of the E/SE leading to excellent upslope conditions. 700mb capping is forecast to dissipate early afternoon.
On SAT, a couple of NE/SW oriented, southward propagating OFBs from yesterday appear both north and south of DEN. Radar doesn't pick these up that well at the moment.
Very sluggish 500mb westerlies over the area will mean very slow moving cells. But anvil ventilation should be enhanced by the right entrance region of a moderate 60kt streak at 250mb. Strong SE 850mb winds should provide adequate midlevel moistening and sustain storm growth.
At this time, favor the corridor between I-76 and I-70 (likely Last Chance area) for potential tornadic storms. Here's to hoping for my son's coolest birthday present
