Pop-Up Severe Weather Expected Through the Weekend

I guess it’s that time of year again…

Due to atmospheric instability over the next following days, severe weather will pop up (mainly in the afternoons), across the Metro Area.  This type of constant instability is not entirely common in the Northeast, as it only occurs when all the ingredients come together during the day (i.e. lifting parcels of moist air as well as a ‘trigger’ of sorts to jump start the storms), but due to a build up of heat and moisture, even winds coming off the Sound can create thunderstorms. Over the past several days, intense lightning storms have made night into day for certain portions of the Tri-State, and it was only several days ago when The National Weather Service confirmed a weak tornado touched down in North Haven, Connecticut.

The primary threat from these ‘pop-up storms’ is flash flooding and lightning, although it would be inadvisable to disregard this threat as nothing, as hail, high winds, as well as the potential for some isolated spin-ups does exist throughout the week.

Remember to stay alert and aware of all current threats and alerts, and make sure you alter your plans accordingly if thunderstorms are in the forecast.

 

Rounds of Storms Firing Up in NYC Metro Area

Thought it was over? Well, guess again…

Over the past hour and a half, a line of thunderstorms brought periods of heavy rain, gusty winds, and lightning to mostly northern portions of the Tri-State Area.  Although this line of storms may have cooled things down a bit, there is yet another, larger line of thunderstorms that has the potential to bring even more severe weather to the Metro Area later on in the evening.  With respect to the first line of storms, although they may not have gotten their act quite together when it comes to supercell development, they still packed a punch able to take down large branches, leaves, and lower visibility to less than a mile in some locations temporarily.

The line of storms that is expected to move into the Metro Area tonight will have even more ingredients necessary for Severe Weather Development in their favor.  After the first line of storms earlier, the Mixed Layered CAPE, instead of dropping off, skyrocketed from 700-1,100 joules per kilogram, to 1,500-2,000 joules per kilogram.  Along with this, there has been a notable increase in Effective Helicity as well as Effective Shear, indicating that stronger and more developed storms are on the way.

The most important thing to remember today is that the storms are not over, and that it will be important to have access to NOAA Weather Alerts via an NOAA Weather Alerts Radio or via Cellular Phone so you can stay informed if Severe Weather hits.

Severe Weather Outbreak and Tornado Warnings

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.
