![]() ![]() 11, Great Lakes ice cover hit a February record low of 2.7%.Ī strong ridge of high pressure kept the eastern United States warm and dry, while California kept getting hit with atmospheric rivers, she said. But Iowa blew past its warmest February by 2 degrees, while parts of Minnesota were 20 degrees warmer than average for all of February, Gleason said. Last month was only the third-warmest February on record. The past three months were 0.82 degrees (0.46 degrees Celsius) warmer than the previous record set eight years ago, which “is a pretty good leap above the previous record,” said Karin Gleason, chief of monitoring at NOAA's National Centers for Environmental Information. ![]() This is just the latest in a drumbeat of broken temperature records, national and global, that scientists say is mostly from human-caused climate change from the burning of coal, oil and gas.Īnd it was the warmest U.S. The Lower 48 states averaged 37.6 degrees (3.1 degrees Celsius), which is 5.4 degrees (3 degrees Celsius) above average. On Friday, the National Oceanic and Atmospheric Administration confirmed that the winter of 2023-2024 was the warmest in nearly 130 years of record-keeping for the United States. Masters said he was bitten by a mosquito in Michigan this year, which he called crazy. this year,” said Yale Climate Connections meteorologist Jeff Masters, who co-founded the private firm Weather Underground. “Long-term warming combined with El Nino conspired to make winter not show up in the U.S. If the radar animation of the last hours shows local thunderstorms or precipitation cells forming and disappearing in an irregular manner, then the forecast is not vey accurate.For a wide swath of the country from Colorado to New Jersey, and Texas to the Carolinas, spring leaves are arriving three to four weeks earlier than the 1991-2020 average, according to the National Phenology Network, which tracks the timing of plants, insects and other natural signs of the seasons. The forecast works very well when weather fronts or large organized precipitation structures are moving regularly, without disappearing or being created. Real weather is more complex than just the displacement of existing precipitation cells. ![]() Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. The rain/snow forecast is computed by estimating the movement of precipitation cells observed by radar and extrapolating this movement into the future. United States: How accurate is the radar based forecast? Moreover, some countries do not operate a weather radar network, and in those countries satellite data is used to estimate rainfall, which is less accurate than a realtime weather radar. Note that lightning is not shown on the forecast, as it cannot be predicted. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually associated with thunderstorms.Ĭurrent lightning strikes are marked with small orange dots on the map (Europe only). The different colours indicate the intensity of rainfall or snowfall. The radar map is updated every 5 minutes with a new radar observation. The weather radar ( United States) shows where it is currently raining or snowing. ![]()
