This Day in National/World Weather History ...
 18 December 1944 → The ships of the US Navy Task Force 38, seven fleet and six light carriers, eight battleships, 15 cruisers, and about 50 destroyers were operating about 300 miles east of Luzon in the Philippine Sea. A small but violent typhoon overtook the task force with relatively little warning. Many of the ships were caught near the center of the storm and buffeted by extreme seas and hurricane force winds. Three destroyers capsized and went down with practically all hands, while a cruiser, five aircraft carriers, and three destroyers suffered serious damage. Approximately 790 men were lost or killed. Fires occurred in three carriers when planes broke loose in their hangars and 146 planes on various ships were lost or damaged beyond economical repair by fires, impact damage, or by being swept overboard.
 18 December 1957 → An unusually late tornado outbreak for the time of year for so far north struck Missouri and Illinois. 18 tornadoes were rated F2 or greater. An F4 ripped through Jackson, Williamson, and Franklin counties in Illinois. Murphysboro was hard hit with 10 people killed. Sunfield, IL vanished completely as an F5 tornado swept it clean.

                   Weather History...

July 1, 1891:

By order of the United States Congress and President Benjamin Harrison, at noon Eastern Standard Time the United States Weather Bureau was officially established within the Department of Agriculture. This was the first civilian government weather agency in the United States, replacing weather observation and forecasting functions that had been performed by military personnel in the Army Signal Service since 1870. The Weather Bureau survives today as the National Weather Service after changing its name in 1970. The state of South Dakota is currently serviced by three National Weather Service weather forecast offices in Sioux Falls, Aberdeen, and Rapid City.

July 1, 1928:

A powerful, estimated F4 tornado moved southeast from 6 miles west of Miller, destroying farms near the start of the path. All buildings were leveled to the ground, including two homes. A check book from one home was found 10 miles away. Estimated property damaged was set at $50,000.

July 1, 1955:

An estimated F2 tornado moved northeast near Bowdle. Two barns were destroyed. A small girl and a pony were reportedly carried a quarter mile without injury. A tornado was also spotted in Emmons County in North Dakota, causing $10,000 worth of damage.

July 1, 2005:

Heavy rains of three to seven inches fell across far eastern Brown, western and northern Day, and most of Marshall Counties in late June causing widespread flooding. The flood waters slowly receded through July 10th. Many township roads and highways were flooded along with thousands of acres of cropland. Water surrounded several homes resulting in people being rescued. Some of the homes were flooded. Many bridges were damaged and roads and culverts were washed out. In Day County, 30 roads were washed out and 15 bridges needed repairs.

July 1, 2006:

With continued little or no rainfall along with much above normal temperatures, a drought expanded and intensified through July across central and north central South Dakota. Severe (D2) to extreme (D3) drought early in July worsened to extreme (D3) to exceptional (D4) across all of the area by the middle of July and remained there through the end of the month. Rainfall was 1.50 inches to 2.25 inches below normal for the month and from 7 to 8 inches below normal for the year. Soil moisture was 4 to 5 inches below normal and lake and river flows were well below normal. Crops and pastures were devastated due to the extreme dryness and burn bans were in effect across all of the area. Many ranchers had to sell off much of their cattle. Throughout July, periodic strong winds, low relative humidity values, along with many lightning storms resulted in tens, if not over one hundred fires across central and north central South Dakota. Tens of thousands of acres of pastureland and cropland were burned as a result of the fires. Hundreds of fire fighters worked throughout the month to contain the fires. The governor of South Dakota declared a statewide emergency and the United States Department of Agriculture declared all of the counties drought disasters. Swan Lake, in north central South Dakota between Lowry and Hoven, had completely dried up from the long period of dryness. The last time this happened to the lake was 30 years prior in 1976. Also, Lake Oahe at Pierre was four feet above its all-time low.
