We probably don’t have to tell you this…but:
Parts of New England have seen the biggest temperature changes over the past 24 hours – upwards of 40 degrees or more! As one example, the temperature at 2 pm in Lawrence, MA was 50 degrees while yesterday’s temperature at 2 pm was 90!
As the NWS reported, the decline in from the high temperatures experienced on Friday to those on Saturday was dramatic, as shown in the two maps below. The average high temperature decline between the two days was in the 30-to-40-degree Fahrenheit range over 24 hours.
The NWS notes in their Area Forecast Discussion that cooler than normal temperatures will continue:
