Sunday afternoon to be dry, rain-snow mix expected overnight


For most, the daylight hours of Sunday will remain dry with plenty of clouds, a brisk southerly wind and highs in the upper 40s-lower 50s, before some big changes later tonight. The Arctic front is still scheduled to roll through overnight spreading a rain to snow mix, rapidly falling temperatures and very strong wind causing potentially dangerous Wind Chill Values.

As of right now, it looks like the scattered rain showers will arrive on the Plateau late afternoon/early evening and transition over to snow between 7pm-9pm Central Time. The Valley will see the steadier rain this evening between 6pm-8pm with a transition to snow between 10pm-Midnight and the Mountains should see the rain by 8pm with a transition to snow shortly thereafter from the higher elevations down to the Foothills.

The "band" of snow will most likely be rather narrow, but the wet ground from the rain will most likely rapidly freeze and any amount of accumulating snow on top of that will cause travel concerns. The bigger impact of this storm will be the Arctic air and just how long it sticks around. We will see temperatures fall overnight Sunday into Monday through the 20s down into the teens during Monday afternoon and will bottom out in the single digits to below zero for some by Tuesday morning.

The strong winds will also cause Wind Chill Values to fall down between -5° to -20° at times from Monday into Tuesday morning. Temperatures will remain below freezing for somewhere around 60 hours in most locations before we see a thaw for the second half of the week. 

Today: Cloudy, breezy and mild with a few stray late day rain showers (30% coverage). High: 52°.

Tonight: Rain quickly changes to snow tonight (100% coverage) as Arctic air pours in. Temperatures will fall through the 20s into the teens by daybreak.

Monday: Continued windy and cold with a few flurries/light snow showers (30% coverage). Temperatures continue to slowly drop through the teens with Wind Chill Values between -5° and -10° at times.
