Weather that was all over the charts for October should give way to a November with near-normal temperatures and precipitation in the Tri-Cities, according to the National Weather Service.

October not only was unusually wet, but in the final eight days of the month four daily temperature records at Hanford also were set and one tied. That included records for both unusually warm and unusually cool days at Hanford, where the Hanford Meteorological Station keeps records back to 1945.

On Oct. 24, a new record for the coldest high temperature for the date was set. The new record is 44 degrees, replacing the old record of 49 set in 1957.

On Oct. 26, another new record was established for the coldest high temperature for the date. The new record is 43 degrees, replacing the previous mark of 49, most recently recorded in 2000.

Three days later, however, on Oct. 29, the temperature jumped to 72 degrees, a record high for the date. The previous record was 70 degrees, set in 1953.

That same day, the low temperature was 50 degrees, tying the warmest low temperature on record for that day. The record was set in 1997.

The next day, Oct. 30, the low was 51 degrees, setting a new record for the warmest low temperature for the date. The previous record was 50 degrees set in 1997.

When temperatures for the month were averaged, they were near normal.

In the Tri-Cities, the average temperature was 54.5 degrees, which was 0.6 degree above normal. At Hanford, temperatures averaged 52.8 degrees, which was 0.3 below normal.

High temperatures in the Tri-Cities averaged 65.9 degrees, which was 0.1 degree above normal. The highest temperature, as measured in Kennewick, was 82 degrees on Oct. 2 and 3.

Low temperatures averaged 43.2 degrees, which was 1.1 degrees above normal. The lowest temperature, as measured in Kennewick, was 36 degrees on Oct. 6.

At Hanford, the highest temperature was 87 degrees on Oct. 1 and the lowest was 29 degrees Oct. 23.

Precipitation for October totaled 1.16 inches in Kennewick, which was 0.56 inch above normal. The heaviest rainfall was 0.26 inch on Oct. 28.

At Hanford, precipitation totaled 1.05 inches, more than double the normal of 0.49 inch. Total precipitation for the first 10 months of the year at Hanford was 5.97 inches, which is 120 percent of the normal 4.99 inches.

In the Tri-Cities, precipitation for the year has reached 7 inches through October, which is 1.4 inches above normal.

The peak wind gust in the Tri-Cities in October was 46 mph on Oct. 16. At Hanford, it was 53 mph on the same day.

If November temperatures in the Tri-Cities are normal, as predicted, highs will fall from 58 degrees at the start of the month to 44 degrees at the end of the month. Normal lows fall from 38 degrees to 32 degrees in November.

Normal precipitation for the Tri-Cities in November is 1 inch.
