Dangerous tornado, hail threat brewing across Midwest, Plains as severe weather expands over more than 130M

Parts of the Midwest and the Plains are once again in the bull's-eye of an expansive severe weather threat that covers more than 130 million people from Texas to New York. There's an increased risk of tornadoes Tuesday spanning a corridor from eastern Iowa into southern Wisconsin and northern Illinois, which is under a Level 3 out of 5 risk of severe thunderstorms, according to the Storm Prediction Center (SPC).

HOW TO WATCH FOX WEATHER

Strong EF-2 tornadoes are possible across a wider area Tuesday afternoon covering Chicago, Milwaukee and Des Moines, as well as parts of southern Michigan, including Detroit, which were added to the threat area Tuesday morning.

FLOOD THREAT INCREASES ACROSS GREAT LAKES AMID HEAVY RAINFALL, RAPID SNOWMELT

Meanwhile, parts of the Southern Plains from Central Oklahoma, including Oklahoma City, to portions of North Texas including Wichita Falls, are also under a tornado and large hail risk where a dryline — the boundary between dry air from the west and warm, moist air from the Gulf — is forecast to set up Tuesday afternoon.

This all comes after severe storms on Monday dropped damaging tornadoes and hail across Minnesota, Wisconsin and Kansas.

A second round of severe thunderstorms will ignite from Texas to New York on Wednesday, with the flood threat mounting for parts of the Midwest and Great Lakes, which have seen several consecutive days of heavy rain.

Power outages remained across Miami, Franklin and Linn counties in eastern Kansas early Tuesday after tornado-warned storms blasted across the region Monday night.

RECORD WARMTH TO PUSH EAST, FUELING ROUNDS OF RAIN AND STORMS ACROSS MAJOR CITIES FROM SOUTH TO NORTHEAST

A tornado injured 2 people and destroyed homes and businesses after ripping through part of Hillsdale, Kansas, shortly after 8 p.m. local time on Monday, the Miami County Sheriff's Office said. Several RVs and campers were also overturned and roads to the community have been closed as police remain on scene to guard unsecured homes and buildings.

A local school is serving as a shelter for those displaced. 

Severe weather also damaged buildings in Ottawa, Kansas, but no injuries have been reported, city officials said.

Severe thunderstorms produced several tornadoes across parts of Minnesota Monday, including one spotted by FOX Weather Meteorologist Haley Meier during live storm coverage outside of Truman, Minnesota. Significant tornado damage has not been reported across the state. 

Exclusive FOX Weather Storm Tracker Corey Gerken also confirmed a tornado near Amboy, Minnesota Monday afternoon.

Storms also produced widespread hail, including golf ball-sized hail in the southern part of the state, along where the warm front set up, south of Minneapolis.

An active spring weather pattern has developed across the Central U.S. with severe thunderstorms likely throughout the week, including another significant tornado threat expected across parts of the Plains and Midwest on Friday.

Tuesday: Tornado threat includes Milwaukee, Chicago and Detroit within 1,500-mile swath of expected storms

The severe weather threat has expanded Tuesday, covering more than 130 million people, spanning more than 1,500 miles from the Big Bend of Texas through parts of New England.

The SPC has issued a Level 3 out of 5 severe risk of severe thunderstorms across parts of eastern Iowa, southern Wisconsin, northern Illinois, and southern Michigan, including Chicago, Milwaukee and Detroit.

A warm front will be re-established across this Level 3 threat area and will amplify storms that cross this boundary. These storms are expected to produce large hail, 2-3 inches in diameter, particularly north of where that front sets up beginning mid-to-late afternoon.

Conditions will be ripe for supercell thunderstorms capable of producing strong EF-3+ tornadoes along or south of the warm front around sunset.

In the southern theater of Tuesday's threat, severe storms capable of producing large hail and possibly tornadoes are expected to fire along the dryline which is forecast to set up over Oklahoma and West Texas.

Storms that produced damaging hail across the Midwest on Monday tracked into Upstate New York late Tuesday morning and will reach New England later in the afternoon and evening.

A Level 2 severe storm threat includes Burlington, Vermont, Albany, New York, and Scranton, Pennsylvania, with damaging wind gusts being the main hazard with the potential for isolated tornadoes.

Wednesday: Third round of storms for Central US; potential for flash flooding

On Wednesday, storms are expected to shift toward the Mississippi River Valleys, with the possibility for damaging wind gusts, hail and tornadoes primarily across a corridor that includes the Plains, the Midwest, the Great Lakes and the Ohio Valley.

In addition to the severe component, thunderstorms will release heavy moisture from the atmosphere, leading to downpours producing 1 to 2 inches of rain.

Localized flooding was already reported in Oconto, Kewaunee and Brown counties in Wisconsin Tuesday, when officials said numerous roads were flooded and vehicles were stranded.

A Level 1 out of 4 risk of flash flooding covers that same corridor from Texas to western New York.
