SPRING SWING IN NATIONAL TEMPERATURES
Temperatures this weekend are a reminder that spring is a season of transitions, and those transitions are often dramatic.
- Temperatures Saturday will be 10 to 20° below normal in most locations east of the Mississippi River, while from the Rockies and westward, temperatures will be 10 to 20° above normal.
- The heat extremes have been more recently pronounced along the immediate West Coast, as Record Highs were set from Seattle to Los Angeles on Thursday.
- Los Angeles recorded its fifth day at or above 90° this March. The previous record was three days (set in 1934, 1988, 1997).
- Most of the Northeast, Appalachians, and Great Lakes will have a difficult time getting out of the 30s on Saturday, while 80s will be common along the Front Range of the Rockies.
Despite the cold spell in the eastern U.S., the overall scorecard still tilts warm for the nation as a whole. With the data that are in through March 24:
- Record Highs are outpacing Record Lows 3 to 2.
- When also considering the Record High Minimums and Record Low Maximums, the ratio is a little less dramatic, but the warm records are outpacing the cold records 5 to 4.
- And even though there have been several individual snowfall records established, like this year in Boston (110.3”), there have been no new snow depth records this calendar year.
- Hot West, Cold East May Be Normal As The World Warms
- Turning the clock back on a global scale shows that even when the U.S. dustbowl era of the 1930s is considered, the previous three decades are warmer, and continue to trend that way.
