Denver is under a winter weather advisory as icy and snowy conditions are expected for Monday morning’s commute.

One to three inches of snow and a glaze of ice are expected for most of the metro area, according to the National Weather Service. That could lead to significant travel issues across the metro area, even though overall snow and ice amounts are expecting to remain relatively low.

The advisory goes into effect at midnight Monday morning. It’s set to expire at 9 a.m on Monday morning.

It will likely still be snowing lightly during the commute on Monday, though, again, it probably won’t be snowing particularly hard — if at all.

But even with lighter expected snow and ice totals, it’s still enough to potentially create lots of travel disruptions on Monday morning.

As the colder air mass rapidly moves in overnight, the cold, dense air will sink to the surface — potentially leaving a narrow layer of warm air just above the surface. That could be significant, as it likely means that tonight’s precipitation will initially start as either freezing drizzle or light freezing rain.

In addition to that, warm weekend temperatures will have the ground on the warmer side. That will likely melt the initial precipitation as it reaches the surface, and as cold temperatures take hold — most areas will wake up to temperatures in the low 20s on Monday morning — it will freeze the initial melted precipitation. All of this could well happen just in time for Monday’s morning commute.

As the freezing drizzle changes over to light snowfall early Monday morning, there may be a glaze of ice underneath the snow, especially on bridges and overpasses that freeze over first. It’ll likely still be snowing during the Monday morning commute, with the layer of ice underneath the snow.

Snow and ice amounts won’t be particularly impressive with this system. Most areas in the immediate Denver metro area probably won’t see more than an inch or two of snowfall. The ground may also be just warm enough that the majority of Monday’s snow and ice melts, and roadways stay mainly wet.

But the timing and possible icy parameters of Monday’s system — likely just before and during Monday morning’s commute — could lead to extra disruption. Plan for a possibly slick and slow ride into work on Monday morning.
