Area Forecast Discussion National Weather Service Cheyenne WY 523 PM MDT Fri Jul 26 2019 .SHORT TERM...(This evening through Saturday night) Issued at 222 PM MDT Fri Jul 26 2019 Fairly quiet so far this afternoon with convection firing mostly just south and east of the CWA. Outflow boundary along the se Wy/Co border has set off a few storms but they are tending to die out after the boundary passes. best chance for convection still looks to be around the mtns and close to the Co border into this evening though noting some Cu formation along the Pine Ridge. Should see more widespread convection over the CWA Sat afternoon and evening as a decent shortwave passes across and interacts with a sfc boundary along the mtns. A few stronger storms possible given instability and some shear. Activity may continue into the night as the wave moves into the Neb Panhandle. Otherwise a bit cooler over the plains Saturday as a weak surface high settles over the northern plains. .LONG TERM...(Sunday through Friday) Issued at 222 PM MDT Fri Jul 26 2019 Looking like a drier pattern over the CWA Sunday and Monday as an upper high builds over the 4 corners area and warms the mid levels a bit.
