Winter storm watches are in effect for the front range of the Rockies from southern Wyoming to northern New Mexico. These watches extend eastward into the High Plains of Colorado, New Mexico, Kansas, Oklahoma, and Texas. The storm associated with this snowfall is not expected to move all that quickly. Thus, heavy snowfall may result more from the duration of snow than the intensity.
Here are the snowfall probability maps from the HPC:
From these images, you can see how the storm will slowly progress out of the Rockies tonight and into the central Plains Sunday and Monday. The total snowfall forecast does not appear as high as the storm a few weeks ago – there isn’t even a moderate chance of 12 inches of snow in a 24 hour period. Still, there’s a moderate chance of at least 8 inches of snow today and tomorrow.
The track of this storm is also expected to differ from the previous storm. Instead of turning northeastward and racing through the northern Plains, this system is expected to slide southeastward through Texas and slow down. It’s also expected to weaken as it’s cut off from the main flow aloft. This southerly track will bring the first snow of the season to the panhandles of Oklahoma and Texas.
As the storm ramps up today, I’ll try to find webcams to post and provide nearly live images of the storm. Unfortunately, I don’t think there’s much in southeastern Colorado or southwestern Kansas. I’ll post what I can find in the Rockies to at least cover today and tomorrow morning.
