The map, produced by Predictive Services at the National Interagency Fire Center, shows the location of lighting that was detected during the 24 hours ending at 6 a.m. MT, July 2, 2015.
Lightning has been hammering parts of California, Utah, Idaho, Arizona, Wyoming, and Nevada during the last two days, especially on Tuesday and Tuesday night. The maps below show the strikes that were detected as well as the approximate amount of precipitation that came along with the storms. The black areas indicate no rain, while red means there was less than 0.08 inch.
The first map is for the 24 hour period that ended at 6 a.m. MT on June 30. The second is for the 24 hour period that ended at 6 a.m. MT on July 1.
The data is from Predictive Services at the National Interagency Fire Center.
This map product, on the National Interagency Fire Center’s web site, is new to me. It is interactive, in that you can toggle on or off many different layers for weather and fuel conditions that affect wildland fire, including lightning, fuel moisture, fire danger, observed precipitation, forecast precipitation, Red Flag Warnings, and current weather conditions. Some of the layers don’t seem to be active, but maybe it is a work in progress.
The map above shows lightning over the last 24 hours by PSA. And yes, I had to research what “PSA” is. Apparently it stands for Predictive Service Area: “geographic areas of similar climate based on statistical correlation of RAWS data”. Unfortunately the lightning map does not include the date and time the data was current. And there is no explanation for the numbers that correspond to the colors, but I assume it is the number of lightning strikes.
The user interface for the site is a little cumbersome and at times non-intuitive, but after you figure it out it can be quite interesting.
Another product from the site is below — Red Flag Warnings for June 28, 2015.
Forecasts for high temperatures and lightning with little or no rain on Saturday have resulted in Red Flag Warnings for areas in Oregon, Washington, California, and Nevada.
As shown in the map below, central Oregon received numerous lightning strikes during the 24-hour period ending at 6 a.m. MT, today June 27, 2015.
As of about 9 a.m. on Saturday, Central Oregon Fire reported 17 lightning fires had been discovered. The largest two were near Brothers, OR in grass or shrub; one was 200 acres and the other was 50 acres. The rest are small.

Isolated dry thunderstorms (with little or no rain) are predicted for some areas in northeastern California, western Nevada, and central Oregon Friday and into early Saturday morning. Land managers are worried about the possibility of new lightning-caused wildfires.

Forecasters with the National Weather Service have published Special Weather Statements with warnings about extreme heat and lightning predicted for northern California, Oregon, and Washington beginning Thursday and through the weekend.
This interesting period will start with near-record, and record-setting heat on Thursday and Friday with high temperatures of 100 to 112 degrees in the valleys. Thunderstorms will be thrown into the equation starting on Friday, initially with little rainfall, raising the possibility for dry lightning. Later in the weekend there will be more moisture with the storms.

Below is a list of fires in Alaska that are currently reported on InciWeb, sorted by size:

A Facebook page called Alaska Climate Info has some amazing, even shocking, images of 46,000 lightning strikes in the state between Saturday and Tuesday morning, and a map showing dozens of fires that are larger than 5 acres each.
In the image below, I believe each tag is a wildfire.
