As the subject suggests, I found a very fascinating weather station (CWOP ID E5552) observation just west of Pueblo, CO from the morning of 12/15/16 ahead of the approaching winter system. The temp jumped from 36º to 65º in just 15 mins! Notice the wind direction shift... the wind shifted from upslope (E) to downslope (W) during this period which resulted in the wild temperature swing. Also notice the response of the different pressures ([from left to right] station, SLP, and altimeter). SLP dropped significantly (11.4 mb) to compensate for the then much less dense air, but altimeter only drops the same as the station pressure. A good example of the difference between SLP and altimeter. Check it out in the screenshots below!
