Record Cold, Snow Blast New York City!

After a very mild and basically snowless winter, New York City, along with many other locations across the northeastern United States were dealt a blast of arctic air and even some snow on Saturday morning. The highly anomalous airmass, which originated over the Arctic Ocean, is responsible for numerous record lows in the region.

As the airmass rolled in late on Friday night, the temperature in New York’s famed Central Park dropped to 36 deg F (2.2 deg C ) which broke the record for May 8th of 37 deg F (2.7 C) set back in 1947. By early Saturday morning the temperature dropped to 34 deg F (1.1 deg C) which not only broke the record for May 9th of 35 deg F (1.6 deg C), also set in 1947, but is the coldest it has ever been on record this late in the season. Although not a record, Saturday’s afternoon high in the city only reached 47 deg F (8.3 deg C). This is not only 21 degrees below average, but more typical of high in early December, rather than early May.

The unusual cold temperatures were accompanied by very rare May snow. A trace of snow was recorded in Central Park, which ties the record set on May 9th 1977 for latest snowfall in a season. The trace of snow is equal to what the city recorded in all of this past February. In nearby Islip, New York, a trace was also recorded, which is more than what actually occurred in February. Much higher amounts of snow were seen in various locales across the northeast. One such place was Sugar Hill, New Hampshire, which recieved 10.5 in (27 cm) of snow.

With the growing season well underway, widespread freeze warnings are in place throughout the region. Given that it is May, prolonged periods of cold cannot be sustained, and a warm up will commence by midweek.

Another Round of Severe Weather Strikes Southern U.S.!

Once again the American South is ground zero for severe weather, in what has been a seemingly endless streak of death and destruction over the last few weeks. The region was hit by a barrage of flooding rains, damaging winds, and deadly tornadoes from Wednesday into Thursday. At least 7 people have been killed, while widespread damage has been reported across several states. 44 tornadoes have been reported during the two day period.

In the town of Madill, Oklahoma an EF2 tornado, with winds between 111-135 mph (179-217 kph), touched down on Wednesday afternoon. The twister is responsible for two deaths. One of the victims was a worker at a local steel factory whose body was found 6 miles (10 km) to the southwest of Madill. The factory where the man worked has been heavily damaged, putting it’s 600 employees out of work.

Onalaska, Texas was another town struck by a deadly tornado. Here, it is estimated that an EF3 tornado containing winds of 140 mph (225 kph) traversed the area. 3 people were killed as the storm ripped through town, uprooting trees, downing powerlines, and destroying homes. According to one local official, 291 homes sustained damaged, 46 were destroyed, and 33 people were injured.

Large hail and extreme flooding were among the hazards dished out by the storm system. Hail up to an inch and a half in diameter (2.54 cm) was reported in several towns across Louisiana, including Livonia. The flooding proved deadly in Louisiana as an elderly man was swept away by the floodwaters in DeSoto Parish. Numerous water rescues were performed in the vicinity as well. 5 inches of rain (12.7 cm) within just a few hours inundated the streets of Charleston, South Carolina on Thursday afternoon.

Death Toll Surges in Wake of Storms across American South

After being pummeled by a relentless storm system over the weekend, residents across the Southern United States are cleaning up and accessing the damage. The storm system delivered a plethora of hazards to the region including hail, flooding rains, and deadly tornadoes. 33 people are confirmed dead, the result of storms that carved a destructive path stretching 1200 miles (1931 km) from Texas to the Carolinas. Over 1 million customers lost power due to the outbreak, while hundreds of homes and businesses were damaged or destroyed.

While the severe weather outbreak lasted Saturday through Monday, Sunday was the busiest day. Not only was Sunday the busiest day of this outbreak, it was the most active severe weather day of the calendar year thus far, and produced the most severe storm reports in one day since 6/28/2018. It also is the deadliest tornado outbreak in the United States since 2012.

There were nearly 60 reports of tornadoes, with most of them occurring in southern Mississippi. Several of them featured very long tracks that contributed to the extensive damage. One such was given a preliminary rating of EF4 on the Enhanced Fujita Scale, containing winds of 170 mph (274 kph). This twister tore through the town of Bassfield.

Tornadoes may have caused the most damage during the outbreak, but other dangerous perils, such as flooding were rampant as well. In the town of Dalton, Georgia massive flooding led to numerous high water rescues as roads were inundated with up to 4 feet (1.2 meters) of water. Governors of the effected states have declared a State of Emergency, in addition to the preexisting declarations due to Covid-19.

Dangerous Overnight Tornado Outbreak Threatens the Southern US

 

An extremely dangerous outbreak of severe storms, including tornadoes, will threaten the southern U.S. late on Easter Sunday through early Monday. Tornadoes and other severe hazards are particularly deadly when they occur at night due to poor visibility and the fact that many people are asleep. Keep your sources of emergency information close at hand and be prepared to seek shelter if necessary!

 

 

A strong upper level trough is pivoting out of the southwest U.S. tonight. Severe storms have already broken out over portions of west Texas with large hail and isolated tornadoes. The system will encounter rich moisture from the Gulf of Mexico on Sunday, fueling more and stronger supercell thunderstorms, especially later in the afternoon into the evening. Unfortunately, the best combination of strong upper level winds and moist instability will come together on Sunday evening over portions of Louisiana, Arkansas, western Tennessee, Mississippi, and Alabama. Deadly tornadoes and damaging hail up to three inches (7.5 cm) in diameter will occur in this region. The supercells will likely consolidate into a squall line that will race into the southeast Monday morning. Here the most widespread threat will be destructive straight-line winds up to 80 mph (130 kph), although isolated tornadoes and large hail may still occur. Major cities in the path of these severe cells include Jackson, MS, Memphis, TN, Atlanta, GA, and Columbia, SC.
