The #summersolstice happens tonight! Summer is the one season in NYC that isn't really getting warmer (in fact, winter is our fastest-warming season), but we don't cool down as much overnight as we did 50 years ago. This is likely due to the Urban Heat Island Effect and higher humidity, both of which prevent temperatures from dropping at night.

Climate change and the 1991-2020 U.S. Climate Normals | NOAA Climate.gov

We're entering a "new normal" for climatological records in the USA.
Now that we're in a new decade, NOAA Climate.Gov is releasing its updated records for 100s of cities around the country. This article has really interesting facts about the resulting changes, including changes to USDA Growing Zones. Check it out!

Every ten years, NOAA releases an analysis of U.S. weather of the past three decades, calculating average values for temperature, rainfall, and other climate conditions that have come to represent the new “normals” of our changing climate.

11/25/2020

The 2020 Atlantic Hurricane season officially ends on November 30th. That doesn't mean storms can't form in December, but historically, the chances go way down. Speaking of historic: as you probably know, this season was a record-breaker. More from NOAA below:

Just in: A hurricane season for the history books --> https://bit.ly/3fvO6u4

As of today, November 24, the Atlantic has churned up a record-breaking 30 named tropical storms: 13 of the 30 storms became hurricanes, of which 6 developed into ‘major’ hurricanes:

NOAA forecasters accurately predicted the extremely active, above-normal 2020 season, which officially comes to a close on November 30.

The season was so busy that the World Meteorological Organization turned to the Greek alphabet for additional storm names for only the 2nd time in history (starting with Alpha) after exhausting WMO’s initial list of 21 alphabetized names that ended with Wilfred.

Several climate factors influenced the record-breaking Atlantic season including the ongoing La Nina, as well as the following phenomena:

- Warmer-than-average sea surface temps;
- Stronger West African monsoon;
- Weaker vertical wind shear;
- Favorable wind patterns coming off of Africa;

Remember: Atlantic hurricane season officially ends November 30 but tropical storms could continue to develop beyond that date.

Make sure you and your loved ones stay hurricane-safe and Weather-Ready.

November 2020 La Niña update: just us chickens | NOAA Climate.gov

La Niña conditions are likely to stick around into the Spring, and a strong event is possible. For the Tri-State area, the impact of a strong La Niña Isn't easy to predict.
One of our snowiest years on record (2010-2011, with 61.9" in the season) happened during a strong La Niña. However, other recent strong La Niña events in 2007-08, 1998-2000 (a 2 year event), and 1988-1989 each had snow totals below 20" for the entire season.

La Niña's a sure bet through the winter. And what's this about the potential for a strong event?

Notice, in addition to Eta, the red shaded area in the Atlantic. Medium range models indicate that the tropics are not slowing down anytime soon, meaning that we may go even deeper into the Greek alphabet for storm names, potentially shattering the 2005 record.

The National Hurricane Center is issuing advisories on Tropical Storm Eta, located over the southeastern Gulf of Mexico - www.nhc.noaa.gov/#Eta

Elsewhere over the Atlantic basin on this Monday afternoon, the shower and thunderstorm activity associated with a low pressure system, located several hundred miles southwest of the Azores, has increased and become better organized during the past several hours. Satellite-derived wind data earlier this morning suggested that the system had not yet become distinct from a frontal boundary in the area, however, it will likely become non-frontal soon. The satellite data also indicated that the system is already producing gale-force
winds. Additional development is expected, and a tropical or subtropical storm will likely form during the next day or two while the system moves eastward or east-northeastward over the northeastern Atlantic Ocean. It has a high (70 percent) chance of formation during the next 48 hours and a high (80 percent) chance during the next five days.

Also, a tropical wave is forecast to move over the central Caribbean Sea, where an area of low pressure could form in a couple of days. Environmental conditions are forecast to be conducive for development, and a tropical depression could form late this week or during the weekend while the system moves slowly westward. It has a near zero chance of formation during the next 48 hours and a medium (50 percent) chance during the next five days. www.hurricanes.gov

This NASA analysis combines land and sea surface temperatures. We know that there’s additional heating in the depths of the ocean, but it’s impossible to quantify because there aren't enough temperature sensors farther below the surface.

UPDATE: September 2020 was the warmest September globally since modern record-keeping began in 1880, measuring at 1.0 °C (1.8 °F) above the 1951-1980 baseline average. The eight most recent Septembers have also been the warmest.

National Oceanic and Atmospheric Administration (NOAA)

Happy 50th Anniversary, NOAA! The National Atmospheric and Oceanographic Administration is the umbrella agency for the National Weather Service, and they also cover everything from the bottom of the ocean floor to the surface of the sun!

It’s official: Today’s the day ... Our 50th anniversary!

NOAA was “born” Oct. 3, 1970, and we’ve never felt more ready to face the next 50 yrs. Join us as we look back at some of our proudest moments.

For all of our accomplishments on behalf of the nation, we are deeply grateful to the hardworking and passionate NOAA workforce, without whom our achievements as one of the federal government’s three science agencies would not have been possible -- or successful.

Smoke in D.C.'s skies today traveled thousands of miles from the West Coast

The story was written in the DC metro area, but it applies here as well. The good news (for us at least) is that the wildfire smoke is lofting high in the atmosphere, not causing problems for air quality near the ground.

The smoke is graying out what would otherwise be sparkling blue skies.

Meteorological Fall began yesterday, and in NYC, the months of September, October, and November have gotten a lot warmer in the past 50 years. The biggest change is in the average overnight low temperature, due to the Urban Heat Island effect and an increase in humidity, which makes it harder to cool down at night.

As the remnants of Laura move toward the Northeast this weekend, the storm will merge with an approaching cold front, enhancing the rainfall. While most of the Tri-State doesn't need more rain, check out New England- much of the region is in a Severe Drought, and could really use the rain!

The tropics are heating up again- unlike Josephine and Kyle, these two potential developing storms are close enough to impact each other’s strength and track, making them harder to forecast and more uncertain. We’ll keep an eye on them for you.

Two areas of disturbed weather located over the Atlantic basin on this Tuesday afternoon continue to be watched closely.

One is a a tropical wave over the eastern Caribbean Sea, and continues to produce an area of disorganized thunderstorms and gusty winds. This wave is moving quickly westward at about 20 mph and significant development is unlikely while it moves across the eastern and central Caribbean Sea during the next day or two. After that time, however, the wave is forecast to slow down, and a tropical depression will likely form late this week or this weekend when it reaches the northwestern Caribbean Sea. It has a low (30 percent) chance of formation during the next 8 hours and a high (70 percent) chance during the next five days.

The other is an area of low pressure located about 1300 miles east of the Lesser Antilles, producing a concentrated area of showers and thunderstorms. Environmental conditions are conducive for development, and a tropical depression is expected to form within the next couple of days while the system moves west-northwestward at 15 to 20 mph across the central and western portions of the tropical Atlantic. Interests in the Lesser Antilles should monitor the progres of this system. It has a high (80 percent) chance of formation during the next 48 hours and a high (90 percent) chance during the next five days. www.hurricanes.gov

Isaias beelines toward us today. A Tornado Watch is in effect for the Tri-State, and we also have the potential for flash flooding as the storm dumps very heavy rain in a short amount of time. Isaias is gone already by tomorrow.

Here are the Key Messages regarding Tropical Storm Isaias, issued by NHC at 5 a.m. EDT Tuesday - www.hurricanes.gov

Most of the impact from Isaias will likely be felt in the Tri-State on Tuesday. Sun returns Wednesday morning!

Did you know that the sea level is rising faster in Miami than in NYC? The reason is fascinating (in my opinion).
The ice sheet in Greenland is so massive, it produces its own gravitational pull! But as the ice melts, the sheet loses mass, which reduces this gravity effect. This causes the water in the ocean to get distributed more evenly, sending more water toward the equator.

As our planet warms, the ocean’s surface is rising. Water expands as it warms, and melting of ice sheets and glaciers on land adds water to the ocean. Learn more about the global mean sea level with these graphs. https://www.climate.gov/maps-data/dataset/global-mean-sea-level-graph

What is a meteotsunami?

Yesterday’s thunderstorms caused a Meteotsunami in the Chesapeake Bay! Learn more about this fairly rare but potentially dangerous weather phenomenon: https://oceanservice.noaa.gov/facts/meteotsunami.html

Meteotsunamis are large waves that scientists are just beginning to better understand. Unlike tsunamis triggered by seismic activity, meteotsunamis are driven by weather events, such as fast-moving severe thunderstorms, squalls, or other storm fronts with a change in pressure. The storm generates a....
