The intensity of extreme winter cold is projected to decrease. (NClimDiv) 1 provides data for temperature, precipitation, drought indices, and heating and cooling degree days for US climate divisions, states, multi-state regions, and the nation from . Please Contact Us. Precipitation This table gives the total precipitation that fell on Burlington during each year from 2010. Warmer and more moist temperatures in Vermont are likely to create more habitat for disease-carrying ticks and mosquitoes. However, in areas where "Equal Chances" (EC) is shown, it means that climate signals do not favor either above- or below-normal, and above-, near-, or below-normal forecast categories are equally likely to occur. This website contains copyrighted images. Some of the earliest records were kept at at U.S. military forts in the 1800s, such as Burlington and Lunenburg(h). Overall, Vermont precipitation has seen no improvement in pH of over time. Title: USGS Current Conditions for Vermont Clouds & Precipitation. Sites on the east side of the Green Mountains seem to have higher summer pHs potentially due to the cleansing effect of moving from west to east over the mountains. This database is created by scanning original documents and keying the numerical information by hand. U.S. Geological Survey An Official Lott, N., D. Ross, and A. Graumann, A forecast of Equal Chances does NOT necessarily mean forecast conditions are expected to be near-normal. Higher spring and fall temperatures have resulted in corresponding changes in the length of the freeze-free season, with later first fall freeze and earlier last spring freeze dates. Vermonts climate is already changing in ways that benefit its agricultural system, including longer growing periods (freeze-free periods lengthened twenty-one days since early 1900s) and milder temperatures (annual average temperature increase of 2F (1.1C) since the 1990s), allowing farmers to experiment with new crops or practices not previously viable in Vermont. [Vermont]. The changing climate also brings agricultural setbacks, such as negative impacts on fruit-bearing species like apple trees that require a sufficient over-wintering period for success in the next growing season. For products which have a "Year Range:", typing in the phrase "por" for a starting range will return information across that location's period of record. . By 2080, the Vermont ski season will be shortened by two weeks (under a low emissions scenario) or by a whole month (under a high emissions scenario), and some ski areas will remain viable. The images below are historical weather documents found in journals, newspapers, and other correspondence that have been scanned and put online for educational purposes (acknowledgement is required).

NOAA Atlas 14 Precipitation Frequency Data Server. The transformations to these climatic data were done to provide users with an intuitive understanding of whether a given months total precipitation or average temperature were similar to or different than the corresponding historical average. State government websites often end in .gov or .mil. experiencing similar NOTE: For Burlington, VT climate, it is recommended that users use the "Burlington Area" location, which includes climate records prior to 1940, when the official observation site was downtown. Changes in Vermonts elevation, terrain, and its proximity to Lake Champlain and the Atlantic Ocean all contribute to variations in climate across the state. The annual number of 2-inch extreme precipitation events has been above the long-term average over the past 26 years (19952020), with the highest number of events occurring during the periods of 1995 to 1999 and 2005 to 2009 (Figure 2e).

Lake Champlain level (in ft) and lake temperature (in degrees F) graphs. Climate of the Northeast U.S. NOAA Technical Report Vermont has experienced little or no exceptional (D4) drought, so there are no D4-level drought impacts recorded in the Drought Impact Reporter. During the extreme hydrologic drought of 20202021, new 30-year record lows were observed across the state. The Standardized Precipitation Index (SPI) is an index to characterize meteorological drought on a range of timescales, ranging from 1 to 72 months. At the same time, multiyear meteorological and hydrological droughts continue to pose challenges for water-dependent sectors.

National Water Information System: Web Interface, Accessibility 1998: Eastern U.S. Average temperatures have increased by nearly 2F since 1900. } The outlooks express forecast probability that temperatures or total precipitation in the 6-10 or 8-14 day period will tend to be similar to the 10-highest ("above-normal"), middle-10 ("near-normal"), or 10-lowest ("below-normal") observed in the 1981-2010 normals period. Station Data. We were unable to display data for this section. Its NOAA Monthly US Climate Divisional Database (NClimDiv)1 provides data for temperature, precipitation, drought indices, and heating and cooling degree days for US climate divisions, states, multi-state regions, and the nation from 1895 to the present. From north to south, Vermont is 159 miles (256 km) long. National Oceanic and Atmospheric Administration, The program creates an online, password-protected, digital database of historical weather and climate data. FOIA An official website of the United States government. Data for the past several decades show long-term shifts in temperature, precipitation, and the risks of certain types of severe weather. Vermonts Global Warming Solutions Act requires a reduction in greenhouse gas (GHG) emissions. The driest multiyear periods were in the early 1910s and the early 1960s. Observations taken from the King St. To evaluate seasonal trends in bulk precipitation pH. Each lake has been monitored under the current VLTM project from 28 to 32 years, making it one of the oldest lake monitoring programs designed specifically to assess acidification. The number of days with precipitation counts the days when rainfall or snowfall (when melted) amounted to 0.01 inches (0.3 millimeters) or more. Get the facts here, including data from the National Oceanic and AtmosphericAdministration. lived in counties with cooler, NIDIS is a multi-agency partnership that coordinates drought monitoring, forecasting, planning, and information at national, state, and local levels across the country. National Oceanic and Atmospheric It is a way to both preserve and share the quality science of our researchers. The release of heat-trapping greenhouse gases, particularly carbon dioxide (CO2), has increased the heat in the atmosphere. Maps are generally updated around the second week of the following season. For more information on climate change and health impacts refer to the Vermont Department of Health Climate and Health website. The Halloween storm of 2019 produced 35 inches of rain in a single day, broke multiple precipitation and temperature records, led to extensive flooding, and caused over $6 million dollars of damage to infrastructure across the state. The winter warming trend is reflected in a below average annual number of very cold nights since the mid-2000s (Figure 2b). November 2022. The flooding resulted in more than $700 million in damages across the state.
