This is a part 2 post to the very active April 10th discussion. The winter storm is just getting underway and warnings (winter storm and blizzard) are just now in effect as this posts. Be safe out there! I’m in St. Louis (missing all the fun) and have no internet connection after my evening meetings. (I know!)
The next 15 hours after noon Wednesday from the HRRR (Figure 1) have about an inch over Longmont with heavier amounts east and west of us.
The GFS, over the next 2 days, ends up giving Longmont 3-4 inches of snow. Add wind and you have a travel mess shaping up Wednesday night into Thursday AM (Figure 2). In Figure 3, this storm largely wraps up in the early morning hours Thursday with some snow flurry chances later in the day.
The longer range forecast:
A big deep south low forms on the heals of this storm and moves up to dump rain on me in St. Louis, then a third storm rolls out of the U.S. Northwest to bring some rain/snow chances back (Figure 3) Friday night into Saturday AM. More on that AFTER the Wed/Thur storm actually wraps up.
