Comments:
This particular storm system gave the area three rounds of showers and thunderstorms. Overall, the storm total was 0.58in., which brings the yearly rain total to 8.66in.. We rated this storm in the "Moderate" category due to rainfall rates and the intense lightning during certain storms as this enitre storm system moved through. Also, this storm could be broken up into two separate storms due to the fact that 24 hours passed from the October 4th precipitation event and the October 5th precipitation event, but we decided to put it together since the showers were caused by the same storm system.

This first round of showers and thunderstorms moved through the area on October 4th. The rain was light to moderate with a total of 0.04in. falling between 7:50pm and 8:00pm. The max rain rate with this part of the storm was 0.98in/hr.. The second part of the storm affected the area on October 5th with the rain starting at 10:10pm and ending by 10:20pm. During those ten minutes we recorded 0.08in. of rain with a max rain rate of 2.76in/hr.. Finally, during the early morning hours of October 6th, a larger storm moved through the area beginning around 2:30am. This storm brought light to moderate rain to the area with some intense cloud-to-ground lightning. The light to moderate rainfall continued through the morning hours and early afternoon ending at 1:00pm. The rainfall total for this part of the storm was 0.46in. with a max rain rate of 0.16in/hr..

In Gilbert, adjacent the Freestone Park, Ken reported a storm total of 0.10in.. Al, in NW Gold Canyon, reported a storm total of 0.67in.. Thank you for your rain reports! The above rain totals were reported to us by private individuals. The accuracy of these reports is unknown.

Wind was not a large factor with this storm system. The max wind speed at our location was from the SE at 25mph on October 4th at 7:49pm. However, during this storm some location did see much higher wind speeds/gusts. As a matter of fact, in Tuba City, AZ on October 5th two tornadoes where reported, and one tornado was reported over the town of Red Lake. Here is the reports from the Storm Prediction Center on these events: "TWO TORNADOS WERE REPORTED ONE WEST AND ANOTHER EAST OF TUBA CITY. STRUCTURE DMG REPORTED AND MINOR INJURIES FROM AIRBORNE DEBRIES." ; "A TORNADO WAS SPOTTED OVER THE TOWN OF RED LAKE. NO DMG OR INJURIES REPORTED AT THIS TIME."

During the first part of this series of storms, lightning was not a concern with only 1,330 strikes recorded all day on October 4th. However, on October 5th we recorded 35,370 strikes with a peak stroke rate per minute of 228 at 2:37pm. On October 6th, as mentioned above, our area experienced intense cloud-to-ground lightning during the early morning hours, with a total stroke count of 30,940.

Below are four graphs (Temperature, Dew Point, Barometer and Daily Rain) which show the conditions before, during and after the storm moved through the area. The area enclosed inside the red box is when the storm system was affecting the area.




The first radar image below shows the line of storms that was moving into the area from the south during the early morning hours on October 6th.
