Minnesota is bracing for potentially significant severe weather later today as a powerful storm system moves across the region. The National Oceanic and Atmospheric Administration's Storm Prediction Center has issued an enhanced risk for severe storms in parts of Minnesota, including the Twin Cities, with the possibility of tornadoes, hurricane-force winds, and large hail.

According to the Storm Prediction Center, the highest tornado threat is expected in eastern South Dakota and southwestern Minnesota. Meanwhile, areas to the east could experience damaging winds of 70-80+ mph. Meteorologists have identified two possible scenarios that could unfold. The first scenario entails a strong atmospheric cap, preventing storm development until late Monday night when storms from South Dakota move in. The second scenario involves storms erupting in western Minnesota this afternoon and barreling towards the Twin Cities.

One model, the NAM 3km, suggests that Minnesota will remain relatively quiet throughout the day due to a strong cap, with storms only developing around 10-11 p.m. The model also predicts a subsequent wave of activity moving in from South Dakota overnight.

On the other hand, the HRRR model indicates the potential for supercell thunderstorms to form in western Minnesota as early as 4-5 p.m., and then track eastward, potentially reaching the Twin Cities metro area by 8-9 p.m. These storms could produce tornadoes and large hail before transitioning into a bow echo, which would bring a damaging wind threat to the metro.

As Minnesota prepares for severe weather, the southern half of the state is also grappling with extreme heat and humidity. Areas including the Twin Cities, Mankato, and Rochester are under an excessive heat warning, with "feels like" temperatures ranging from 100 to 110 degrees. In fact, one small town reported a scorching heat index of 120 degrees.

It's crucial for residents in the at-risk areas to stay informed and take necessary precautions. Keep an eye on local weather updates and be prepared to seek shelter if severe weather warnings are issued. Additionally, residents in the southern half of the state should take extra care to stay hydrated and avoid prolonged exposure to the extreme heat.

As the storm system approaches, meteorologists will closely monitor its progression and provide further updates on the potential impact to Minnesota. The models also hint at the possibility of extreme heat returning by the middle of next week, further emphasizing the need for residents to stay vigilant and prioritize their safety.

As the situation develops, authorities urge the public to remain cautious and heed warnings from the National Weather Service. Stay tuned for further updates and stay safe during this period of elevated weather risks.
