DENVER — Cold weather and snow will continue, with another 2 to 4 inches for the Denver metro area by Tuesday morning. Monday began with a record low temperature of 15 degrees, breaking the existing mark of 17 degrees, set in 1933. The normal low temperature for April 13th is 33. The afternoon temperatures in the upper 20s may also set a new record for the coldest maximum temperature for the date, which currently is 27 degrees, also set in 1933.
Periods of snow can be expected throughout the afternoon, evening and most of tonight as a strong upper level jet stream pushes across Colorado. The winds aloft are creating turbulence and instability in the atmosphere and that will cause periods of moderate snowfall.
A Winter Weather Advisory is in effect for the foothills, western and southern suburbs and the Palmer Divide through Tuesday at 3 AM for up to 6 inches of snow. Much of the snow will melt on pavement through the day, but roads may become quite slick tonight and early Tuesday.
Tuesday morning lows will be in the low to mid-teens, but the snow will end and skies will be clearing. Expect the highs to climb back to the low to mid-40s, but that is still nearly 20 degrees colder than normal for mid-April.
Another storm system will move into Colorado beginning on Wednesday. Snow will develop in the mountains, with a mix of rain and snow late in the day for Denver and the eastern plains. More accumulating snow is expected for Denver Wednesday night and Thursday, along with unseasonably chilly temperatures.
Highs will not bounce back to the 50s until Friday, BRRR! Fortunately the weekend should be milder with highs back into the low 60s.
