Extreme levels of thunderstorms are expected along the east coast on Thursday, and April is expected to bring significant thunderstorms and hurricane activity across the Lower 48.

“Review your strict weather protection practices for the potential for dangerous weather today,” the Center for Storm Forecasts stressed in its public severe weather forecast released early Wednesday.

Even outside the destructive hurricane line that is expected to form, the surrounding winds could blow at speeds of up to 50 mph before any storms.

“Damaged wind blows down trees and power lines,” wrote the National Weather Service in Mobile, Ala. “Widespread power outage expected.”

All over Mississippi, Alabama, Louisiana, Tennessee and Kentucky are surrounded by wind counseling and high wind warnings – the warnings are spreading across southern and Ohio Valley.

In the midst of the dry, gusty winds in front of the storm system and at its rise, a Risk of fast moving fire In the Tennessee Valley and Texas areas on Wednesday, several similar flames erupted Tuesday.

Heavy thunderstorms lashed southwestern Missouri, western Arkansas and the Ozarks in southeastern Oklahoma and the Ozarks in northeastern Texas northeast of Interstate 35. Southwest. That line went south from the low pressure system on the corn belt, which was energized by the approaching over-wind disturbances.

The same deep surface low-pressure zone will strengthen the south-southeast wind to the front, pulling a mild and humid wind from the Gulf of Mexico northward across the south. The clouds remaining from the Martian storms will block the daytime heat, meaning the mass of the air will not “juice” otherwise.

Severe thunderstorms, even with relatively moderate fuels, such as a change in wind speed / direction with a cut or height. It screams low to the north surface, thanks to a roaring low-lying jet stream, or a river of wind moving fast a mile or more off the ground. That is, any clouds that grow high enough will have a tendency to rotate.

It is not clear how far east the line will remain in late Wednesday or early Thursday before it breaks and weakens.

The storms that formed Wednesday morning took the form of QLCS or semi-linear convection systems as they worked through the afternoon in Louisiana. It’s basically a squall line with embedded kinks of rotation, each of which can turn into a hurricane.

In terms of organization, it is worth noting a few things:

  • Moving rain with thunder Much Quick across the deep south. This can reduce the risk of weather forecasting being issued.
  • With strong jet stream winds, it is easy to mix speed on a thunderstorm surface. That means winds of 60 to 80 mph for thunderstorms.
  • Except for thunderstorms, winds of up to 50 mph can be expected from the hurricane line and then up to 35 mph in the wake of storms as the winds blow out from the northwest.
  • With QLCS there is enough wind shear to support scattered rapid-forming, brief and irregular hurricanes. Due to the rapid forward movement of the line, it does not take long for a pair to cause EF2 + damage. There may be some embedded rotating thunderstorms or supercells in southern Mississippi, the Delta in Louisiana, or the southern hemisphere in southern Alabama.
