Three Denver Cyclones in a Row & The Life and Death of Tropical Cyclone Dominic

You are going to hear the word "cyclone" an awful lot in this blog entry.

For the past three days in a row, we have had a Denver Cyclone form over the metro area. I'm not going to get too into the formation process of this mesoscale phenomena but with soutwesterly winds aloft and southeasterly winds at the surface, the air tends to back and turn south along the foothills. Check out this radar image below.

The cyclone gave us some mild upslope flow which kept the low clouds in again today. Higher clouds moving over the area continued to seed the deck and give us some nice bursts of snow in bands. I got about 1.5" at my apartment over the course of the day.

Currently in the tropics:

10S Dominic - The storm that formed only yesterday has made landfall on the northwest coast of Australia today. Winds didn't top out much higher than 50kts, so it wasn't too powerful. It was moving fast enough that hopefully it didn't cause any flooding concerns either.

98P Invest - This area is expected to form into a tropical cyclone.
