Pacific Cyclone

I measured 0.9 inches of rain in Monterey, CA over yesterday evening and night. We also received hail that was the most clear hailstones I have ever seen. It was a very exciting rain storm. The power went out for about 20 seconds.

The HRRR analysis at 0000 UTC and 0400 UTC (4:00 PM and 8:00 PM Pacific Time) shows the cyclone approaching northern California.

This is the GOES-West satellite image at 0011 UTC on November 27th.

Hot September

Temperatures in Utah, Colorado, and Wyoming have been hot considering we are in September now. Below shows that the 2-m air temperature in the HRRR analysis for yesterday afternoon is above the 95th percentile temperature by several degrees.

My weather station in Spanish Fork registered a 100 degree temperature on Labor Day during our backyard BBQ. It was hot. Below shows the September 1-3 temperatures since 2013. This has been a warmer start to September than we are used to. Over the next week we will begin to cool down as the upper-level ridge moves further east. Then those fall temperatures will start to creep in.

San Francisco Fog Tracker

The San Francisco Chronicle recently published a "Bay Area Fog Tracker" web page. It is a useful tool for watching fog and clouds in the bay area, and it will be fun to look at when I start working in the area. I was credited with helping the developers understand how to access and use the GOES-West data.

Alaska fire in near Provo Utah

The Alaska fire gave us a little worry around midnight when we could see the flames from out bedroom window. Fortunately the fire has spread uphill and has been hindered by the rain. I spent a good chunk of time watching the helicopter dump water and the tanker drop retardant on the fire. It has been an interesting day.

Cold June Day

A cold front rolled into town last night. It is much colder than usual for this time of year.

Below is the HRRR analysis for 12:00 noon (Mountain time) colored by departure from the 95th percentile. Blue is saying that temperatures are 6-10 degrees colder than the 5th percentile temperature.

My camp trip tonight will feel more like fall camping than summer camping.

Here is a time series of temperature at the University of Utah (WBB) and at Logan airport (KLGU) further north.
