Extreme Storms, Tornadoes Expected in the Heartland by Wednesday

An impressive storm over Alaska’s Aleutian Islands has sent a powerful southward dip in the jet stream which will hit the continental U.S. Tuesday and Wednesday, bringing severe weather, including possible tornado threats.

The Weather Channel reports that the cold air mixed with warmer, humid air in the lower levels of the atmosphere could produce severe thunderstorms. They also state that since this weather prediction is a few days early, that it is uncertain to measure the level of the tornadic threat.

The main threat from severe thunderstorms are gusting winds, hail, flash flooding, and the possibility of tornadoes. The tornadic threat level can range depending on how unstable the air mass becomes, which is something that cannot be easily predicted. Winds are expected to pick up in the midsection late Tuesday, with sustained winds of up to 40mph by Wednesday with gusts at 50 to 60 mph or more.

Regions on the northwestern part of the storm will see high winds and snow. Colorado and Kansas were placed under blizzard watches and high wind watches were issued for Texas, Nebraska, Oklahoma, Colorado, and Kansas, according to ABC News.

November has seen its fair share of severe weather in the past. Nearly two years ago, 72 tornadoes made their way through 7 states.

Monday Storm Brings Rain, Snow, Mudslides, and Flash Flooding to California

California and other parts of the western United States – including Sierra, Nevada – saw the first winter-like storm of the season on Monday. the storm brought heavy rain and snow and even caused a 20 car pile up due to gusts of wind bringing up dust. Five people were minorly injured.

San Francisco saw an inch of rain and other Bay Area cities had an inch or more of rain thanks to the cold front from the Pacific Northwest. Traffic accidents and power outages were widespread across the region according to ABC News. Mudslides also blocked roads close to Livermore.

Mountain areas around Lake Tahoe on the California-Nevada border reported a foot of snow. The Sierra Nevada mountain range had storm warnings for heavy snow from Kings Canyon to Yosemite that were in effect until late night hours. Areas above 9,000 feet saw 5 inches of snow by early evening, and snow levels were expected to fall to 5,000 feet.

Yolo, Lake, and Colusa counties were issued flash flood warnings according to the weather service.

The snow in Sierra could help with the drought that has hit California. California counts on snowpack to feed reservoirs. The storm also hit areas that were burned by wildfires earlier this year.

Major Hurricane Drought Reaches Record 117 Months

The continental United States has not been hit with a major hurricane in more than 117 months, a record according to the Hurricane Research Division of the National Oceanic and Atmospheric Administration (NOAA).

NOAA’s tracking of storms dates back to 1851.

A “major” hurricane is defined as a storm of Category 3 or higher.  The last major hurricane was Hurricane Wilma in 2005 which reached Category 5.

The scale does not mean smaller storms could not cause damage, but that major storms are most likely to cause catastrophic damage and significant loss of life.  The most recent storm to cause damage while not being considered a “major” hurricane was Hurricane Sandy, a category 1 storm that was downgraded by the time it made landfall in the northeastern United States.

The streak is not expected to end this Atlantic hurricane season as “El Nino” is especially hot and among the strongest in the last 50 years.  That warm current of air mixed with colder than normal Atlantic Ocean water decreases the possibility of major storms.

“Even if El Niño went away tomorrow, which it won’t do, we would still forecast a below normal season because the Atlantic is so cold,” Phil Klotzbach, a research scientist at Colorado State University told the Miami Herald. “When you get that combination, it’s really lethal for storms.”

Category 4 Hurricane Dolores, currently raging in the Pacific Ocean, is so far off the coastline that forecasters do not believe it will make landfall in Mexico or the United States.

Tropical Depression Bill Causes Flooding

Tropical Storm Bill weakened Wednesday to a tropical depression but is still bringing massive amounts of rain to south Texas.

“Rainfall will result in significant flooding across central and eastern Texas and into southern Oklahoma through Wednesday night,” AccuWeather meteorologist Chyna Glenn told USA Today.

However, Texas is not the only state bearing the brunt of Bill’s wrath.

Southern and eastern Oklahoma have reported more than a foot of rain including just over 13 inches reported at Newport, Oklahoma. Interstate 35 in southern Oklahoma was closed due to flooding and one exit had to be closed because the rain dislodged boulders which rolled into the roadway.

Multiple rivers including the Red River, Trinity River and Washita River are either at flood stage or are forecasted to be reaching flood stage by the weekend.  The National Weather Service said the flooding from the Washita River in Oklahoma could be “catastrophic.”

The storm is moving eastward into Missouri and Arkansas, bringing heavy rain and the possibility of flooding in those states.

Deadly Storms Rage Through Texas and Oklahoma

Officials in Texas and Oklahoma say that at least 11 people are dead and over a dozen missing following a massive storm front that roared through the two states.

Record rainfall fell in many communities and flooding caused mass devastation.

Houston officials say that two people were found Tuesday and that they likely drowned in the massive flooding in the area.  Authorities were telling residents to not leave their homes.   Over 70,000 customers are without power in the Houston area.

The National Weather Service reported 11 inches of rain in six hours throughout southwest Houston.  Over 130 water rescues had to be conducted throughout the city.  The weather was so severe that the Houston Rockets NBA team told the people who came to their playoff game to stay inside the arena in their seats until the passing of the storm.

“We’ve seen flooding before, but not nearly to this extreme,” said Gage Mueller, a Houston resident for the past 40 years and Houston Rockets employee who stayed overnight at the Toyota Center because it wasn’t safe to go home. “It rains and it rains and it rains, and there’s really nowhere for the water to go. … It’s ridiculous.”

Texas Governor Greg Abbott declared disasters in 37 counties.

“You cannot candy coat it. It’s absolutely massive,” Abbott told reporters after he viewed the devastation in the region.

One of the storm’s victims was 18-year-old Alyssa Ramirez, president of the student council at Devine High School who was driving home from her senior prom.  She called 911, she called her father and then the flood waters rose too fast for her to be rescued.

The flooding was so strong that a vacation house next to the Blanco River was pushed off the foundation and rushed downriver into a bridge.  Only parts of the home have been found.  At least one person was killed by the flooding of the Blanco river.

A dam near Highway 71 broke causing the highway to be blocked.

Substantial El Nino Predicted

Scientists say that the El Nino effect is under way in the tropical Pacific.

Australia’s Bureau of Meteorology says a “substantial” El Nino event could take place before the end of the year.  Forecasters say that the El Nino is in early stages but the potential for extreme weather is real.

U.S. scientists initially said that El Nino had arrived but characterized it as “weak.”  Australian officials countered their U.S. colleagues’ claims.

“This is a proper El Nino effect, it’s not a weak one,” David Jones, manager of climate monitoring and prediction at the Bureau of Meteorology, told reporters. He said that El Nino could bring much lower than normal rainfall and enhance the country’s drought conditions.

“You know, there’s always a little bit of doubt when it comes to intensity forecasts, but across the models as a whole we’d suggest that this will be quite a substantial El Nino event.”

After the Australian model was released, U.S. forecasters on Thursday revised their statements and said that El Nino could bring much needed rain to California.

“We’ve seen continued evolution toward a stronger event,” NOAA official Mike Halpert told TIME. “Last month we were calling it weak, now we’re calling it borderline weak to moderate.”

“Stronger El Niños interrupt tropical rainfalls. That rain fall shifts and Indonesia and Austrailia become drier than average,” explained Halpert. “They’re not looking forward to El Niño shutting the tap off.”

February Could Show Record Setting Cold

Meteorologists say that February 2015 could end up as one of the coldest months in Detroit history with an average temperature of just over 13 degrees.

“I’m doing some calculations but I think we are on track here to have the coldest month ever in Detroit, the way things are looking,” said AccuWeather’s Dean DeVore. “And it’s going to be brutally cold here today.”

“It’s like an open spigot from like Barrow, Alaska down to the Great Lakes. Meantime, they can’t buy a drop of rain on the west coast for the past month or so,” AccuWeather’s Dave Bowers added. “It’s been wicked. It really is quite a contrast. The western half of the country is having an extremely warm winter, and here it really is more like the Northwest Territories in our backyard.

“We’re running about almost 12 degrees below normal his month.”

Other cities across the U.S. have been setting records for cold temperatures.  Cleveland fell to -5 on Monday breaking a record set in 1873 and the first time since 1889 it was below zero on February 23rd.  The temperature hit -17 on Friday, shattering the previous low and was just 3 degrees short of the all time record for low temperature in the city.

Ann Arbor, Michigan hit -7 on Monday which broke the previous record for the date set in 1900.

“Milky Rain” Across Pacific Northwest

Scientists across the Pacific Northwest are investigating a rain that left a residue on cars in two states.

The “milky rain” fell on both Oregon and Washington states, leaving a powdery resident on vehicles and buildings.  Samples have been collected by the Pacific Northwest National Laboratory and the Benton Clean Air Agency in an attempt to discover what was in the rain.

So far the scientists have competing theories.  One is that a volcanic eruption in Japan has resulted in volcanic ash mixing with clouds to create the rain.  The other is that dust from central Oregon somehow mixed with a storm.

The National Weather Service has taken a mostly impartial view, stating dust storms were the likely cause but it could not rule out volcanic ash.  The NWS says they do not have the equipment necessary to analyze the rain and discover its origin.

Robin Priddy of Benton Clean Air says that air monitoring stations detected nothing during the rain but that they don’t feel it poses a health risk.

“We don’t have any reason to think there’s anything wrong, but there’s no reason not to be cautious if you’re concerned,” she added. “You may want to wash it off your car with water, rather than with your hands, and avoid touching it and breathing it in.”

Iselle Weakens To Tropical Storm Before Landfall

Hawaii residents dodged one bullet when Hurricane Iselle weakened before making landfall Friday.

Tropical Storm Iselle was still the first named storm to strike the islands in 22 years.

The storm game ashore around 2:30 a.m. local time just outside of Pahala.  The storm carried sustained winds of 60 m.p.h.  No deaths or major injuries have been reported so far.

Officials say that heavy rain has been falling on the island of Oahu that has been causing localized flooding.  Roadways have been impassible and residents have been told to avoid traveling.  Downed trees have blocked the H-1 freeway.

Power is out to large parts of the islands.  Officials confirmed at least 21,000 homes are in the dark and the total is likely to climb as the storm continues.

Hurricane Julio, which has strengthened to a Category 3 storm, is now tracking to move just north of the islands but could still bring heavy rain from the outer bands to the areas currently being hit by Iselle.

Polar Vortex Drives Down Summer Temperatures

The polar vortex is back…but many Americans are happy to see it arrive this time.

The vortex is bringing cool summer temperatures into the Midwest and south that remind many residents of early September rather than the middle of June.  In some areas, record low temperatures are being set and the daily highs are the lowest in history.

Mobile, Alabama, on the Gulf of Mexico, reported a low temperature of 64 degrees Thursday morning, breaking a 128-year-old temperature record.  Huntsville, Alabama tied a record low of 59 degrees set in 1945.

Nashville, Tennessee tied a record set in 1886 of 57 degrees.  Other cities setting temperature low records included Kansas City, Missouri and Omaha, Nebraska.

Forecasters say the cool air from the vortex is going to expand eastward through the rest of the week and into the weekend, bringing down temperatures from Michigan to southern Louisiana.

The temperature shifts have also caused unusual weather incidents.  Waterspouts formed over Lake Erie on Sunday and meteorologists say the other Great Lakes are at risk for waterspouts because of warmer waters mixing with colder air.
