A cold front moving in from the plains is expected to arrive in our area tomorrow evening. The North American Mesoscale Forecast System (NAM computer model), forecasts a line of thunderstorms to develop over central Pennsylvania and New York before making its way over the NYC Tri-State by 8 pm ET.
Weather360 is forecasting frequent lightning, hail, high winds, and potentially a few tornadoes in these storms tomorrow. The Storm Prediction Center (SPC) forecasts an ‘Elevated Risk’ for severe weather tomorrow, meaning that strong storms are likely with the potential for isolated tornadoes.
Already today the main parameters for severe storm development (CAPE, shear, helicity, and ML LCL) are already favorable for strong thunderstorms. Please have access to a cellphone, television, or radio tomorrow in the event that the National Weather Service issues a severe thunderstorm, flash flood, or tornado warning. Tornadoes can and do occur in this area of the country, please take shelter immediately should a warning be issued for your area.
ALERT: The National Weather Service in Albany, New York has issued a TORNADO WARNING in effect until 4:30 PM Eastern Standard Time. The National Weather Service is also maintaining a TORNADO WATCH for the entire NYC Metro Area until 10:00 PM EST July 1, 2016. Heed all warnings set out by the National Weather Service and take all necessary common sense precautions.
This evening into tonight, several rounds of potentially severe thunderstorms are expected to move through the NYC Metro Area, bringing with them damaging winds, hail, lightning, and torrential rains. The first round of storms has already produced several severe thunderstorms and one storm capable of producing a tornado. Please be advised that in order to receive up-to-date weather alerts and warnings, one will have to consult the National Weather Service via Weather Radio or online. Weather360 estimates there is a 66% chance for Severe Weather Development to continue throughout the NYC Metro Area going into tonight.
These storms are expected to continue for up to several hours, creating the possibility for widespread power outages and downed trees and tree limbs.
For more information, please consult the National Weather Service while we here at Weather360 will continue to inform you of upcoming threats via our YouTube Channel or right here at Weather360.net.
Over the next several hours, more lines of potentially severe thunderstorms are expected to line up across portions of the Upper Midwest, bringing hail, strong winds, and some isolated tornadoes. As of 2:30 CDT, lines of heavy rain and thunderstorms are developing over portions of Southern Iowa, and are expected to make their way east into Illinois, parts of Wisconsin, and parts of Minnesota. The Storm Prediction Center (SPC), has most of Western Illinois under an ‘enhanced risk’, meaning that the potential for multiple severe storms does exist, and that the threat of tornadoes is elevated as well.
Starting tonight, strong to severe thunderstorms are expected to bring heavy rains, high winds, hail, and potentially some tornadoes from Eastern Oklahoma to Alabama. This same storm system is expected to move across the country and will eventually bring some rain to the East Coast as well.
As of 00 UTC, 8 PM EDT: Thunderstorms moving to the southeast from western portions of Virginia are maintaining enough strength to produce storms capable of damaging winds, hail, frequent lightning, and heavy rain as to classify them as severe. Thunderstorms developing in upper portions of the Midwest have the potential to produce tornadoes and more severe weather as night approaches, these thunderstorms are all moving to the east-southeast.
The Tropics: Newly formed Tropical Storm Claudette has maximum sustained winds of about 50 MPH and is moving to the Northeast off of the Mid Atlantic coast to the southeast of Nantucket. The storm is expected to make landfall near Nova Scotia as a Tropical Depression with some winds and rains, along with rip currents.
Tomorrow’s forecast: Thunderstorms developing in the Midwest will have moved far enough east to begin to affect locations in and around NYC and other locations along the I-95 Corridor. With a high temperature hovering around the mid 80’s and clouds moving in early on in the day, the heat index is likely to be lower than that of yesterday, meaning that temperatures will not feel as hot as they did earlier today. Later on tomorrow, more showers will start to move in and the potential for thunderstorms, some occasionally severe, increases.

Starting early this evening severe thunderstorms moving in from Pennsylvania and the Midwest into our area. For locations in and around the city thunderstorms will arrive this evening and potentially cause some severe thunderstorms capable of producing some damaging winds, heavy rain, hail, frequent lightning, and potentially some isolated tornadoes. For locations in and around the city, the severe side of these storms will likely move out by very early tomorrow morning and will begin to taper off as some rain.
Already areas from Ohio to the Cape are under Flash Flood Watches, meaning when the rain moves in later today there will be the potential, much like a few days ago, for some flash floods to occur. If the National Weather Service does think that there is the potential for flash floods imminently over a specific area, they will issue a Flash Flood Warning, in which all weather radios and cellular devices in the specified area will start sounding an alarm to warn the public of the danger (likewise in the event of a tornado). Remember to turn around if you see standing or moving water, the apparent depth of the water may be different from the true depth of the water.
In the event of an alarm sounding in your area whether it be from a cell phone or from a radio, heed ANY AND ALL advice the message offers to ensure safety today and tonight.
Remember also to check the National Weather Service’s website (weather.gov or noaa.gov) if you believe there may be a severe threat either near or at your location over a short period of time.
ALERT: OVER THE NEXT 2 HOURS, A VERY INTENSE AND SEVERE LINE OF THUNDERSTORMS WILL BEGIN TO MOVE INTO THE NYC AREA, THESE THUNDERSTORMS WILL LIKELY BE CAPABLE OF PRODUCING LARGE HAIL, DAMAGING WINDS, FREQUENT LIGHTNING, AND POTENTIALLY SOME ISOLATED TORNADOES.
An enhanced risk for severe thunderstorms and tornadoes does exist today now for the NYC Metro Area, this means there is an elevated likelihood, or enhanced likelihood of 1-2 inch in diameter hail, frequent lightning, and a few potential tornadoes. The enhanced risk set out by the SPC (spc.noaa.gov), also advises that due to an elevated risk of severe thunderstorms and tornadoes, that everyone keeps an eye to the sky and to any watches or warnings that are set out by the NWS/NOAA. Here at Weather 360 we advise this as well, but also that you do NOT ignore watches or warnings and common sense, such as “going indoors as thunder roars”, or to take over immediately if there is a potential threat to life due to a weather event.
Please stay tuned to Weather 360, but remember to keep an eye to the sky and to check the NWS periodically for any new watches or warnings that may regard you personally.
BREAKING NEWS: Multiple tornado warnings issued last night for places in Virginia, Maryland, Delaware, Pennsylvania, and New Jersey
The remnants of Tropical Storm Bill, while moving over Virginia still Tropical Depression Bill, brought in several lines of extremely dangerous and severe thunderstorms accompanied with rotation sufficient enough to produce tornadoes. These thunderstorms also dumped whatever was left of Bill’s moisture as well, in some places over 3 inches of rain fell in less than an hour. There were many flash flood, river flood, and flood warnings issued for areas from the Midwest to New Jersey last night as well, causing the need for some high water rescues by local fire departments and others. For anyone anywhere in the United States that may be impacted by a tornado (basically everywhere), remember that although it may be interesting to watch and videotape a tornado or any type of severe storm, whenever the warning goes out for you, take all precautions and heed every warning in order to stay safe.
Hurricane Blanca, now Tropical Storm Blanca, and soon to be Tropical Depression Blanca, has made landfall on the Baja California north of Cabo San Lucas with winds of about 50 miles an hour, which has created some rough surf and dangerous rip currents in an around the area.
Tropical Storm Blanca was only about 48 hours ago a massive category three, major hurricane, with winds over 130 miles an hour, but due to the lower water temperatures near the Baja California, the storm rapidly weakened and will continue this weakening trend until becoming a remnant low that will bring some moisture to portions of the lower US, and possibly could have a slight affect on the Northeast, but nothing terribly significant.
Areas in and around NYC have TORNADO WATCHES posted. A TORNADO WATCH means that conditions over a large portion of land are more favorable than average for the development of tornadoes, please check with the National Weather Service (NWS) on weather.gov for specific watches and warnings that may affect you.
