Most snow to fall in one day during recent years in Washington DC. Since then, the record amount of snow to fall in one day at Washington is 16.4 inches (41.7 centimetres) on February 11, 1983. When this happens, we look for more cold weather outbreaks in the eastern U.S., and that could lead to more snow. These extremes were measured at Reagan National Airport near downtown Washington and go back to 1946. This takes a look at winds in the stratosphere. Storm Team4 also reviews something called the Quasi-Biennial Oscillation (QBO). This year, snowfall in that area of the world has been a little late, but it's starting now to really increase. Normally, cold and snowy weather there during this time period could mean a colder-than-average winter for us and one with more snow. The warm water of the Pacific should also help to bring more moisture in from the west.Īnother factor to consider is Siberian snow cover in October and early November. For example, warm water in the Atlantic Ocean and the Gulf of Mexico should help produce more moisture during storms in the D.C. There are numerous other factors at play in addition to El Niño. Other factors involved in predicting a snowy winter That’s a big number - and Storm Team4 expects a big winter. So over those other El Niño winters (1957-1958, 83), we got an average of 32.1" per winter. While El Niño might have been similar that year, other factors are not, and Storm Team4 is taking that year out of the equation. The winter of 1972-1973 was actually our least snowy winter on record, with just 0.1". The average snowfall over those four winters was 24" - but we said we hit the jackpot only almost every time. to 5 p.m., accumulating snow is likely near D.C. We reviewed four similar El Niño winters: 1957-1958, 1965-1966, 83. The winter storm will hit the southwestern suburbs first, Storm Team4 says. area has hit the jackpot in regards to snowfall almost every time. Looking at previous years with similar conditions, the D.C. This developing El Niño is looking to be a strong one. What to know about El Niño's effect on winters in the DC area In our area, it normally means more snow, but let’s dive into the details. El Niño has a profound influence on the weather around the globe. They are also predicting above-average precipitation in our region - and we agree with this as well.Įl Niño has set up in the equatorial Pacific, and that could lead to more snow, including the potential for some big snowstorms. The National Oceanic and Atmospheric Administration (NOAA) is currently predicting above-average temperatures for our region this winter, and we agree with this. Now, as we look toward the winter of 2023-2024, we could be feasting quite a bit more.
