Many St. Louis-area residents were still enjoying a long weekend and the end of the Christmas holiday when the flood warnings first went out on Dec. 26. 

Over the next days, the Mississippi, Missouri and Meramec rivers rose to dangerous heights at unprecedented speed in some areas. The water spilled over levees, put water treatment plants out of service, and swamped thousands of homes and businesses in riverside communities.

A three-day forecast of heavy rain and out-of-season thunderstorms has placed the St. Louis area under a flash flood watch through Monday afternoon. The flood watch began Saturday at noon.

“Even though the calendar says December, Mother Nature doesn’t think so,” said National Weather Service meteorologist Ben Miller. “This is a system more typical of fall or actually spring.  There’s going to be some scattered thunderstorms that are going to produce some heavy rain fall.”

Last Friday, the St. Louis office of the National Weather Service picked up something pretty unusual on its radars.

As first reported by Citylab’s John Metcalfe, meteorologists detected a cloud-like formation that kept moving around and changing into odd shapes. After some analysis, they concluded that the “cloud” was in fact a giant swarm of monarch butterflies, headed south on its annual migration to Mexico.

Missouri's overall drought picture is vastly improved this summer over what it was during last year's extreme heat and dry conditions.

Still, drought remains an immediate threat to portions of the Show-Me State. Mark Fuchs is a hydrologist with the National Weather Service office in St. Louis.

The National Weather Service says there were a total of nine tornadoes in the St. Louis region on Friday night.

Oppressive heat and triple-digit temperatures continue to blanket the Midwest from Ohio, down through drought-plagued Indiana, Illinois and Missouri.

With high temperature records being surpassed left and right the National Weather Service is forecasting St. Louis will reach 108 degrees for the second day in a row.

The hot temperatures and dry conditions are particularly hard on those whose jobs involve being outside.

March’s average temperature in St. Louis this year is almost 15 degrees above normal. If the forecast holds true tomorrow, St. Louis’s unusually high temperatures will make this the warmest March on record.

National Weather Service Meteorologist Mark Britt says the average temperature this month will be almost 61 degrees.

“The previous record of 1910 was only about 57.5 so that’s a considerable breaking of the record,” he said.

A band of light to moderate snow has made its way to the St. Louis area this morning.

The National Weather Service says a winter weather advisory remains in effect until six o’clock this evening for a variety of weather conditions, including snow, blowing snow, sleet or freezing drizzle and rain.

Jim Sieveking, a meteorologist with the National Weather Service, says the snow is making the morning commute difficult.

The year 2011 got off to a strange start following a rare winter tornado on New Year's Eve. It was one of a number of severe weather events during the cold weather months, followed by the F-4 tornado that hit north St. Louis County and Lambert Airport in April, and plenty of flooding.

Snow accumulated through much of the St. Louis region overnight. The snowfall caused visibilities to fall below one-mile at times.

The snow caused accidents in the St. Louis metropolitan area. I-55 northbound at I-44 westbound downtown was closed starting at 1:30 a.m. due to a fatal accident. It reopened at around 5:30 a.m.

More violent weather could be headed to the St. Louis metropolitan area.

Although as of 7 a.m. this morning, no severe weather warnings have been issued, the National Weather Service is expecting a significant severe weather outbreak today.

Meteorologist Melissa Byrd with the National Weather Service, says the weather will effect most of Mo. and Ill., especially over the eastern half of Mo. and the southern half of Ill.

The threat of severe weather has moved south and east of the St. Louis Public Radio listening area, though flood warnings remain in effect along many of the area rivers. The National Weather Service is also warning of possible flash flooding, and has issued an urban and small stream flood advisory until 1 a.m.

The St. Louis office of the National Weather Service has released its Spring Flood Outlook. Hydrologist Mark Fuchs says the potential for spring flooding is much higher than usual, especially along the Mississippi River, but Fuchs says the data doesn't predict significant flooding in the St. Louis area.

  • The National Weather Service extended the blizzard warning this morning to include at least parts of the St. Louis metro area. The blizzard warning now includes St. Louis City, St. Louis County, Madison County and St. Charles County. The blizzard warning is in effect until noon Wednesday. Forecasters say wind gusts could reach 30 to 40 mph Tuesday afternoon.

A tornado Wednesday night at a Boy Scout ranch in western Iowa killed three 13-year-old Scouts and a 14-year-old Scout staff member. More than 40 others were injured.

The new round of thunderstorms is likely to hit southwestern Minnesota, northeastern Iowa and Wisconsin and may spark tornadoes, the National Weather Service said. As much as 4 inches of rain are expected in those areas, with hail and damaging winds likely.
