Meteorological events that happened on April 9th:
Here is a piece of weather folklore stating "circle around the moon, it will rain or snow soon". The circle that you can sometimes see around the moon is caused by refraction of light through ice crystals. These ice crystals are quite high in the troposphere and are usually associated with a thin layer of cirrus clouds. Often this layer of ice crystals will precede a developing storm by 24 to 36 hours. The circle does not mean it will rain or snow, but it can be an indicator that there may be a chance of precipitation in the next couple of days.
Oregon Inlet, NC was widened ¾ of a mile by a powerful nor'easter.
The Great Penobscot River Flood occurred in Maine. Bangor, ME had several bridges washed out. Some areas received 6 inches of rain in two days.
Perth, Western Australia recorded its hottest April day on record, dating back to 1897 as the temperature reached 100°.
Boston, MA recorded 9.1 inches of snow, which would stand as the April record until 1982 when 13.2 inches fell.
The temperature dropped below freezing at Sioux Falls, SD. That in itself is nothing special, but the fact that the temperature at Sioux Falls did not drop below freezing again until October 23rd of this year, means that it was the longest such stretch on record. This gave the Sioux Falls area 197 days freeze free days in a row.
The deadliest tornado in Oklahoma history tore through the northwest part of the state. A vast majority of the destruction and loss of life was in Woodward, where 108 people perished, and more than 700 others were injured.

The tornado first touched down near the community of White Deer, in the Texas Panhandle, crossed through the northwest Oklahoma counties of Ellis, Woodward, and Woods, and finally dissipated near Saint Leo, Kansas. The tornado was up to one and one half miles wide as it clipped along at more than 40 mph, along the 221 mile long path through the three states.

Numerous wildfires spread across central Oklahoma. The event began as a fairly strong surface low pressure system moved through northern Oklahoma, with an associated dry line positioned over central Oklahoma. Extremely dry air, combined with westerly winds gusting well over 50 mph, created conditions that allowed wildfires to grow out of control. Many homes and structures were burned, primarily in and near Midwest City. Luckily, no one was killed as a result of the fires.
A severe weather outbreak across the Midwest and the Southeast spawned as many as 31 tornadoes across Iowa, Kentucky, Tennessee and North Carolina.
