Several Wyoming climate sites recorded unusually high temperatures and one rainfall record over a two-day period, according to posts from the National Weather Service forecast office in Riverton. The reports covered measurements at local airports and noted ties and new highs for mid-January dates. The agency posted details on Monday and Tuesday about records at Big Piney, Riverton, Buffalo, Lander and Casper airports. Forecasters outside the state also discussed a possible southward shift of the polar vortex later this month.
Recent reports:
- The NWS-Riverton said six weather records were reported broken across Wyoming over two days.
- Monday: Big Piney Airport reached 46°F, breaking the Jan. 12 record of 41°F set in 1999; Riverton, Buffalo, and Lander airports tied record highs at 54°F, 63°F, and 60°F respectively.
- Tuesday: Casper Airport reached 55°F (previous record 52°F, 1953); Lander hit 61°F (previous 58°F, 1953); Riverton recorded 60°F (previous 55°F, 2021); Big Piney reached 47°F (previous 42°F, 1994).
- Buffalo Airport recorded 0.03 inches of rain on Tuesday, exceeding the previous Jan. 13 rainfall record of 0.02 inches set in 2005.
- Forecasters and outlets noted that the polar vortex is a broad region of cold air that can shift southward in winter and that Arctic air may affect parts of the eastern U.S. later this month.
Summary:
The warm readings produced multiple local temperature records and a small rainfall record in mid-January at several Wyoming airports. Forecasters have reported the potential for the polar vortex to send colder air into parts of the United States later this month, so conditions may change; the timing and extent of any colder outbreak are undetermined at this time.
