MSLP Surface Chart thru May 5
All Snow High Resolution (near term)
The Albertia Clipper is on its way and as of this post, just into US airspace in Montana. It is scheduled to hit Utah and Colorado and is presently looking like it might miss Utah or be a weak rain event. This is storm 91 and 91.5. There was an omission on the Long-range Forecast chart. On the chart, there are two Utah storms in a row, storms 91 and 92. The omitted storm should be in between those two for the date of the 28th.
This system will arrive about 6 hours early and begin as rain for Colorado. Temps will be warm, in the mid 40’s to low 50’s at surface level. Below is the surface level temperature chart thru May 5th. Click to animate. The clipper brings a nice cold shot with it.
This is looking like mainly a rain event, with the exception of Loveland and Arapahoe Basin, where it should be all snow. Upper elevations at Breck and Copper should see 1-4 of snow. A-Basin and Loveland should be in the 4-8 range with a powder day watch in effect for Friday.
GFS Long Range Forecast thru May 10
We are going out a long way for this GFS, which normally I would not go that far out, but the GFS does have a handle on what is coming according to the pattern. Below is the Colorado forecast calendar for Arapahoe Basin (posted March 25) that was assembled over the last 4 cycles.
If the Lont-Range Forecast Prediction Chart were to continue thru May, the dark blue dates would be on the chart. The other shades are the storms occurred through an amplified part of the pattern. This time of year, the pattern is lifting to the north and east, so there is no guarantee that the storms will reach Utah or Colorado, but they will be there and if they miss, they will likely miss north and east.
Below is the blend of models. After the Clipper system, on the Aspen chart, you can see there is some agreement as you get to Wednesday thru Friday next week.
