A couple of factors went into adjusting snow totals from last night’s to this morning’s model runs. First, models initially backed off on snow totals last night but this morning increased them. Second, the snow intensity this morning is a bit heavier than anticipated and it began snowing a bit earlier as well. All of this points (if everything else in this storm stays the same) to higher snowfall accumluation.
Here’s the latest for the Palmer Divide and around the front range:
Models this morning have been very consistent with totals in these amounts. Not anticipating any more changes to these totals unless something falls apart or the storm strengthens.
Pretty good sized storm on our hands. Already seeing reports of tough travel conditions not only in Denver but areas South towards the springs and Palmer Divide. Remember, a Winter Storm Warning means travel is not advised. If you can stay off the roads today that’s definitely a good idea. If you have to travel make sure you have a survival kit and any necessary supplies in your vehicle!
If we see any more updates we will be sure to pass them along, but looks like the storm is moving in!
