Time lapse shows march towards spring at Hanford
Expect warmer and rainier-than-usual weather this April in the Tri-Cities, says the National Weather Service.
It should be a welcome change for Tri-City residents.
March broke a record for cold weather that has stood for more than 100 years, plus a record for snow that has stood for more than half a century.
High temperatures in a typical April in the Tri-Cities are usually about 63 degrees at the start of the month, rising to 70 at the end of the month. Lows typically warm from 40 to 45 through the month.
Normal rainfall for April is about 0.6 inch.
Some of that rain should fall late this week as spring break wraps up for many area schools.
The forecast calls for a 60 percent chance of rain Friday, a slight chance rain Saturday and a 50 percent chance of rain Sunday in the Tri-Cities.
Temperatures should be close to normal, with highs in the low to mid 60s forecast Thursday through Sunday.
March one for the record books
What a difference a month makes.
A month ago on March 4 and 5 the low fell to 1 below zero in Pasco, according to the weather service.
The average temperature for the month, as recorded in Kennewick, was 37.6 degrees, or about 10 degrees below normal.
It was cold enough to break the previous record — set the century before.
The previous record was set in March 1897, when the average temperature was 39.9 degrees, according to the weather service.
The Tri-Cities had as much as 8 inches of snow accumulation on the ground in early March, easily setting a record.
Monthly records that are mostly complete back to the winter of 1948-49 for Kennewick showed no snow on the ground in most Marches.
The Hanford Meteorology Service reported that it was the snowiest March at its station north of the Tri-Cities since records began being kept during World War II. The station recorded 4.4 inches of fresh snow.
It also was a Hanford record for snow depth, with as much as 12 inches of snow on the ground as far into the month as March 7. By March 19 only a trace of snow was left.
