A quick update tonight on our weekend system. For the most part our discussion from earlier today remains valid, so please reference it for further timing, impacts, and overall discussion here.
Main change tonight is to up totals a bit for the Colorado Springs area. We'll go 4 - 8" in the city, with 6 - 12" possible on the west and southwest sides of town. Otherwise we'll hold steady. Generally looking at 4 - 8" east of I-25, and 6 - 12" west of the interstate.
As we sit tonight, it looks like the heaviest snow for the greater Denver area moves in by early to mid afternoon on Saturday, and continues into Saturday night. We're likely to see snow off and on through Sunday, though generally of the lighter variety. There could be several hours Saturday PM that we see pockets of very heavy snow up and down the I-25 corridor between Colorado Springs and Fort Collins. If you are planning on traveling Saturday, your best bet is to do so in the morning if at all possible.
We see some data tonight suggesting even higher totals are possible than what we have indicated here, but, not enough to sway us outside of bringing COS up with the rest of the pack. Might we see some "boom" snowfall in spots (especially west into the Foothills)? Absolutely. But at this point we think the impacts remain the same whether we see 6" or 12"+. It'll be snowy and travel will be difficult Saturday PM and well into Sunday for many areas.
Look for areas of snow to continue tonight, mainly across Northern Colorado, before gradually coming to an end as we head toward day break Saturday. Most locations will see a break in the snow (or perhaps no snow at all) until midday Saturday.
The radar as of 10:30pm Friday shows those areas of snow, but generally not around the Denver metro at this time.
Again, for more please reference our post from earlier, and otherwise... let's see how this one shakes out! March is Denver's snowiest month on average, so this a great way to kick things off. If you're in the mood for snow, here's a post we did some years back on Denver's top 5 biggest March snowstorms.
Stay tuned! Barring any big changes by morning we'll likely hold on any updates in the morning. Remember, this is a long duration event, so we could see those snow showers lingering well into Sunday night in some areas. Your totals from this storm won't all come tomorrow.
If something changes with the forecast, however, we'll pass that along. In any event, please share your reports and images in the comments below. Enjoy the snow and stay warm!
