Issued at 1239 PM MST Sat Nov 14 2026 A negatively tilted trough is moving over the area this afternoon. Moisture has increased significantly at mid and upper levels as this system approached the area. As of early this afternoon, the DCVZ was just to the east of Denver, with very light showers to its east and north. We still have a bit of a dry layer around 750mb across the plains, and with how light the precip is, it could struggle to make it to the ground in some areas until the layer starts to saturate more. Overall rain amounts are expected to be very light for much of the plains. Snow showers are moving into the mountains from the west and south as of early this afternoon. Coverage of snow showers this afternoon and evening will be best south of I-70, with most likely accumulations around a trace to 3 inches above 9000ft. Elevations around 8000ft to 9000ft could see a rain/snow mix today, but accumulations are unlikely. Overnight, we`re expecting more fog development across the plains. The REFS currently has a medium to high chance (50-75%) that portions of the I-70 and northern I-25 corridors will see fog with visiblities less than 0.5 mile in the early morning. Fog should start to clear around 10AM give or take an hour. Upper level ridging begins to build over the area again on Sunday. Warmer and drier conditions will prevail Sunday through much of Tuesday. On Tuesday, an upper level trough will move onto the West Coast. Winds at mid levels will strengthen as the pressure gradient tightens between the upper ridge and trough. However, the strongest winds are forecast to remain to the south and east of our area. The trough will weaken and move east, sending a shortwave through the area early Wednesday. Precip chances will increase late Tuesday in the higher terrain as the shortwave approaches. The shortwave will be moving rather quickly and the southwesterly to westerly winds aloft are not super favorable for our area, so impacts from this event will be rather limited with snow totals around an inch or less for the higher elevations. For the plains, a cold front is forecast to move through sometime Wednesday, bringing slightly cooler temps for Wednesday into the end of the work week. Rain chances remain low (
