With the snowstorm in full swing at the end of the season after spilling a foot or two feet of snow into the north-central United States, a new storm system threatens to provoke the next meteorological storm.
This time, the south will be the target of potentially violent weather conditions. A tornado outbreak is possible on Saturday, with a widespread risk of wind damage. More violent storms could break out on Sunday.
The storm south of this weekend and the central US cyclone that preceded were both fueled by a very active jet-stream model that could cause a new storm next week.
The threat of severe weather this weekend
Unlike the snowstorm that just passed – which was based on an icy Arctic air supply, the weekend storm will attract very hot and humid air from the Gulf of Mexico. Severe weather is possible Saturday from east Texas to Mid-South, then Sunday from the north coast of the Gulf of Mexico to the Ohio Valley and the southern Appalachian Mountains.
Strong, high-altitude winds appear ready to mingle with unstable air near the ground to trigger a regional tornado outbreak in parts of northern Louisiana, Arkansas, Texas and Mississippi. Saturday. Although these are the likely hot spots, it is still possible to move into the high-risk area.
The National Meteorological Service's Storm Prediction Center has reported a moderate risk of severe storms for the second time this year. At the 4 out of 5 level, this is the second highest level of risk on the 0 to 5 scale of the center. The issuance of a moderate threat of threat in early spring is historically unusual and suggests confidence in the expected severity of the storms.
"In addition to locally damaging winds and hail, strong tornadoes can also occur, during some of the most intense storms," writes the center in its forecast for Saturday released early Friday morning.
Shreveport, La., As well as Greenville and Vicksburg, Miss, are among the population centers of the moderate risk area.
Although the risk of heavy tornadoes is probably concentrated in the moderate risk zone, areas in the reinforced (level 3 out of 5) or light (level 2 out of 5) areas, including Dallas and New Orleans, are also concerned. advised to stay tuned and have a plan in case of bad weather. Storms are likely to move quickly, so there is short time to act.
The big wave in the jet stream responsible for the storms is heading east over Sunday, while other violent storms are likely to occur in parts of the Ohio Valley, in the Appalachians and Florida. Wind damage may be the main threat, but more tornadoes are also possible.
Believe it or not, the blizzard that just hit the plains and the Midwest is paving the way for this violent weather event. Since this first storm is moving north into Canada rather than dragging a cold front toward the Gulf Coast, the moisture on the south may remain in place rather than being swept away.
A historic snowstorm ends
The widespread deep powder was left as a result of the blizzard. In some places, drifts are as high as five feet or more!
Much of South Dakota has accumulated one to two feet of snow. Numerous totals approaching both feet have been reported in south-central states, south of Interstate 90. The highest totals are White River (26 inches) and Ideal (24 inches). .
In east-central South Dakota, the Hurons took 18 inches on Wednesday and Thursday, and will add to the total once Friday's amounts added.
The 18-inch was the most over two days in April or later in Huron. There was also a snowstorm in the first 10 months of the month, and the two snowiest days since March 2002. Similar numbers, about two feet tall, came from the northeastern part of the state and from the west from Minnesota.
In addition to threatening all-time snowstorm records in areas where totals have reached and exceeded both feet, many daily snowfall records were surpassed during the event.
A small sample includes Mitchell, S.D., where 15 inches demolished the old four-inch record. Fargo and Grand Forks, North Dakota, also recorded daily records. The records were spread across several states, including sites such as International Falls in Minn. Alpena, Mich; and Cheyenne, Wyo.
Here are the top totals in states that have seen at least one foot of snow.
- Terry Peak, S.D .: 30 inches
- Lander, Wyo .: 27 inches
- Madison, Min .: 20 inches
- Havana, N.D.: 17.5 inches
- Eli, Nb .: 16 inches
- Winter Park, Colo .: 15 inches
- Albion, Mount: 13 inches
- Townsend, Wis.: 12 inches
More next week?
Although it's a bit too far to say much for sure, it looks like another storm system is going to cross the center of the United States next week.
The indications are that it can take a track somewhat similar to the weekend event. If this is the case, it would appear that winter weather outweighs other spring weather conditions, such as weather and floods.
With parts of the Mississippi River Valley and the surrounding forecast to pick up as much as half a foot of rain until mid-week and snowmelt from the recent snowstorm, it appears that the number of floods is increasing again over the next two weeks.
