Meteorological events that happened on April 8th:
We tend to think that the relative humidity can go no higher than 100%. In fact, inside of a cloud a condition known as supersaturation can occur where the relative humidity can reach 102-103%. This condition is caused by the different attractive properties of ice and water and results in the growth of cloud droplets.
Snow at Atlantic City, NJ was deep enough to support an early spring sleigh ride.
Bakersfield, CA dropped to 28°; their lowest April temperature ever.
A big spring snowstorm buried the Potomac Highlands of West Virginia with 34 inches of snow at Wardensville, 30 inches at Moorefield, and 29 inches at Romney.

The San Luis Obispo, CA oil fire continued to burn out of control for the second day engulfing 900 acres. Many tornado vortices resulted from the intense heat of the fire. One such tornado traveled 1,000 yards, picked up a house and carried it 150 feet, killing the two occupants inside.
Record heat occurred across the eastern U.S. Philadelphia, PA hit 90°, New York City 85° and Washington, D.C. hit 93°. Our nation’s capital set three records in a row of 92°, 94°, 93° from the 6th - 8th.
Snow began to fall over central Oklahoma during the previous evening and continued to this day.

The Oklahoma City snowfall totals of 0.8 inches on the 7th, and 3.3 inches on the 8th, remain daily records. In fact, the 3.3 inch snowfall on the 8th is the most ever to fall on any single April day. The 4.1 inch total for the month continues as the greatest April monthly snowfall total.
Light to moderate snow whipped by strong winds completely blocked all streets in Dodge City, KS and all roads and railroads from the city.

Drifts up to eight and ten feet and perhaps even higher were piled over the streets, walks and yards.

A cold front crossing the Northern Plateau and the Northern Rocky Mountain Region produced high winds in northeastern Wyoming. Winds gusting to 69 mph at Sheridan, WY downed power lines and caused property damage.
Strong northerly winds ushered cold air into the north central U.S. The strong winds, gusting to 60 mph at Rapid City, SD and Williston, ND, reduced visibilities in blowing dust over the Dakotas.
Many cities in the southwestern U.S. reported new record high temperatures for the date. Phoenix, AZ equaled their record for April with 104°; established just the previous day. Borrego Springs, CA hit 111° setting an April record and the earliest date in the season of 110° or higher. Daggett, CA had a high temperature of 100°.
