Wednesday Morning Storm Update–A Good Start

Don’t be fooled, the main low-pressure system is still west of us. What we have seen so far was a shortwave trough caught up in the flow ahead of the main storm. This is the frustrating portion of the storm, where forecasters start second-guessing everything.

Here is NOAA’s best guess at the current surface map.

Notice the tightly packed lines from Utah to Arizona. Those concentric circles show the strength of the low pressure. Flagstaff airport reported gusts earlier this morning of 72 mph! Temperatures have fallen dramatically with the frontal passage. Also on the map above you can see a dashed blue line with triangles on it from western Utah into Nevada. This indicates another secondary trough is developing behind the main area of low pressure.

Here is Wunderground’s interpretation of the current surface map.

Either could be correct, both tell me despite the current lull, the storm should ramp back up, the temperatures are going to drop and the winds are going to pick up considerably.

Nothing has changed for the forecast. So far the snowfall has outperformed the models. The roads were warm overnight so the snow did not accumulate very much on the surfaces. These wet roads may flash freeze as the colder air moves in.

What snow was left on my roof in my backyard is now blocking me from my measuring site, but it appears 8 inches of wet snow have accumulated as of 6:30 am.
