MONTHLY WEATHER PATTERNS AND GLOBAL CLIMATE DRIVERS...

The mean 500 MB anomaly pattern for North America featured an anomalous upper level ridge across the north-central Pacific Ocean (indicated by warmer colors in Figure 7), an upper-level trough over the western United States (shown by cooler colors in Figure 7) and a weak upper level ridge positioned over the southeastern United States. This pattern led to warmer than average tempeatures across the mid-Atlantic and southeastern U.S., and colder than average temperatures across a large part of the western U.S. While not shown, the mean 500 MB anomaly pattern is also consistent with climate anomalies associated with negative values of the Pacific North-American Index (PNA) and positive values of the North Atlantic Oscillation (NAO). Negative PNA and positive NAO values were prevalent for much of the middle to latter part of February. The NAO and PNA are two of the main climate drivers that influence wintertime temperature and precipitation patterns across the Northeastern U.S.

For Vermont and northern New York during the month of March, the Climate Prediction Center is forecasting an enhanced chance for temperatures and precipitation to be closer to average.

La Nina continued to steadily weaken through the month of February. By the end of February, sea surface temperatures over the equatorial Pacific Ocean basin (used to monitor ENSO conditions) were at least 1 degree Celsius cooler than normal. Recently, a pool of above-average temperatures has emerged across the far eastern Pacific Ocean, which also indicates a weakening La Nina climate signal. Latest ENSO forecasts issued by the Climate Prediction Center indicate a continued weakening of La Nina, with ENSO-neutral conditions predicted during the late spring/early summer months. Through March, potential U.S. impacts from La Nina include an enhanced chance for drier than average precipitation over the southern states, Central Rockies and the central U.S. Plains states. Below-average temperatures would also be favored for a large portion of the northern tier of the U.S. (excluding New England), with an increased chance for warmer than average temperatures for the southeastern U.S.
