Tuesday offers the warm before the storm with mild temps as we await our next snow

Tuesday, March 12th, 2019 5:08am MDT

As we all have come to know and love about Colorado, the next couple of days will provide stark contrasts in weather for Thornton. Today will see unseasonably warm temperatures which will soon be followed by what may be a significant snowstorm.

For today, partly clear skies start us off then we will see some clearing leading to mostly sunny skies for the morning. The afternoon and evening then see an increased in cloud cover.

Winds will be light and out of the north. Temperatures will push toward a high near the 60 degree mark, well above the average high of 51 degrees for the date.

Ahead of the coming low pressure system, this evening some light rain showers will be possible and likely after midnight. Overnight lows tonight will be in the mid-30s.

As for the coming storm, a Winter Storm Watch will be in effect from noon Wednesday to midnight Wednesday. The National Weather Service warns that moderate to heavy snow during the period coupled with strong winds will create hazardous conditions, particularly Wednesday afternoon and evening.

Rain tomorrow morning will make a switch to snow in the late morning / early afternoon and the afternoon commute tomorrow looks to be a rough one as a result. Here in Thornton, we are thinking 3 to 6 inches is looking likely at this time between Wednesday and Thursday morning. This will be coupled with wind gusts during the day tomorrow that could push to 50 mph.

As always, track and timing remain the wildcards and we are still 24 hours or so from this system hitting in earnest. For us, the transition from rain to snow and when that occurs may serve to increase or decrease any potential snowfall totals. An earlier transition tomorrow morning will drive up totals, a later start will offer lower totals.

Almost certainly, the biggest impacts are going to be on the eastern plains where blizzard conditions will occur.
