For millions of people from Midwest to Northeast this week, the potentially dangerous ice threat from the developing winter storm is too early to know where the storm tracks. , The Fox Prediction Center said that there was a possibility that the frozen rain could sound.
One of the recent storms of the Great River, which is hitting the west coast with heavy rain and mountain snow, plays a role in developing the latest winter weather.
FOX FORECAST CENTER said that the low -pressure system would develop beyond the plains by Tuesday, but would initially lack the water required to strengthen.
When the future system moves east, a powerful southern jet stream begins, drawing warm water in the eastern half of the United States.
The setup creates a clearly defined warm front, separates the frigid air north, and soaks the south in the swamp.
The problem is that warm air moves to an area with a shallow layer of subrozen air near the surface. That is when there is a possibility that a problem may occur.
FOX FORECAST CENTER stated that it could cause freezing rain. However, the computers predicted models still agree to the storm truck, as expected at this time, whether it moves east, or whether a new coastal lowness along the east coast. plug.
The first scenario contains a more powerful low -pressure system that occurs in the plains and remains a dominant system.
As a result, a stronger jet stream draws warm and wet air, leading to the frozen rain along the 90 -of -the -the -western regions of the Inter -State Highway 90 corridors.
The scenario may bring out a remarkable attachment to cities such as Iowa Demoin. Chicago, Illinois. Shiracuus, New York. Burlington, Vermont.
“It covers a large area,” said Fox's Meteorological Meteorological scholar Craig Herella. “It's not like a thin and narrow area where the frozen line is often seen. You can see a thin and narrow band. This is a little wider, especially for commuting.”
Furthermore, the frozen air increases rapidly to the upper west, causing heavy snow to the north of the ice belt.
“Please do not marry the place, but the top of the ice accumulation may be the idea that one -tenth to one -quarter can be married,” he said. Merwin said. “It's enough for a power outage, so I know that the trip is confused, but there is a possibility of losing power. So, if you are in the zone, we recommend that you grab extra supplies.”
In the scenario 2, weak low -pressure systems in the plains develop a new coastal system along the east coast, taking over the dominant system.
The weaker the low -level jet stream, the less frozen rain over a wide range. However, in some areas such as Ohio Valley and Pennsylvania, there is still a possibility that serious ice threats can still be seen.
This scenario does not spare from the worst icing of Demoin and Chicago, and at the same time shifts Sirakusu and Burlington to a full event.
The FOX prediction center stated that if the first scenario was deployed, the large-scale stretch of the I-90 could see important ice adhesion. It can have a significant impact on traveling throughout the region.
The stronger flow of jet pushes the frozen rain footprints to part of the New England, but the heavy rain can limit the accumulation of ice by simply rinsing before freezing.
If the scenario 2 is played, the worst icing is likely to be avoided in the Midwest, and there is a shift to the snowy results of New England.
However, icing in line with the I-90 seems to be still there.
This situation is still a few days later, so the prediction may change. Download the free Fox Weather app so that you can confirm your notifications for changes in predictions.
