Looking Ahead 28 Days from December 16, 2022; Plus Weekend Report; Plus Excerpts from NOAA Four-Season Outlook

Updated at 6:32 p.m. EST Monday, December 19, 2022 (Our regular evening report will be published tonight).

Once a week we show many of the actual forecast maps not just provide the links to these maps. This makes it easier for the reader. Our report provides a separate forecast for Days 1 and 2, Days  1-5, Days 6 -10, Days 8 – 14, and weeks 3 and 4. We also include a next-day and 10-Day Global Average Temperature and Cumulative Precipitation Forecast. This provides information that is useful to readers in terms of planning their activities for the weekend and the next 28 days. Over the weekend and into Monday there will be frequent updates of the short-term forecast.

Looking out 28 days, what we see is:

  • For Temperature: The previous colder-than-normal air mass that entered the Northwest is moving east and being replaced by warmer-than-normal air from west to east.
  • For Precipitation: The evolution of the predicted Southern Tier drought for the first part of 2023.

We have also included the January 2023 and the JFM 2023 Outlook from the NOAA Seasonal Outlook issued on December 15, 2023.
