Numerous factors have been considered in the preparation of the “2025-2026 Winter Outlook” including the likelihood of another winter season with La Nina conditions across the equatorial Pacific Ocean. In fact, La Nina has been the dominant player in the tropical Pacific during four of the five winters this decade with colder-than-normal sea surface temperatures persisting during these seasons. While La Nina is likely as we head into the winter, it should be relatively weak and may transition into “neutral” territory during the second half of the season. As such, teleconnection indices related to other parts of the world have been closely analyzed including the Quasi-Biennial Oscillation (QBO), Arctic Oscillation (AO), and North Atlantic Oscillation (NAO) as they may play a bigger role than normal in overall winter weather patterns. The trend in these teleconnection indices can provide us with some clues as to the temperature and pressure patterns that can be expected during the upcoming winter season and to the prospects for “high-latitude blocking” events to take place. The combination of all these factors and a look at “analog” years with similar sea surface temperature and QBO patterns to today leads me to believe that this will be a colder-than-normal winter season across much of the eastern two/thirds of the nation including the Mid-Atlantic region with nearly normal to slightly above normal snowfall amounts on the table.

After a cool start to the week, temperatures today should climb to the comfortable lower 70’s to go along with plenty of sunshine. The weather becomes more unsettled again later in the week with the chance of showers by the time we get to Wednesday night and Thursday.

The weather looks decent across the southeast US for much of the remainder of the week featuring plenty of sunshine each day and comfortable temperatures. The key player for the weather across the eastern and central states will be strong sub-tropical high pressure centered over Texas during the next few days.

A coastal storm that has been impacting much of the Atlantic seaboard during the past few days will finally weaken and exit off to the east later today. Weather conditions will be slow to improve in the Mid-Atlantic region, but the mid-week should feature some sunshine in the area ahead of the next cold frontal system. That cold front will pass through the region on Wednesday night and it’ll usher in a chilly air mass with temperatures on Thursday likely to struggle to climb above the 60-degree mark for afternoon highs despite plenty of sunshine…there will be a noticeable northwest wind as well.

Low pressure off the east coast will continue to influence our weather today with cloudy skies, breezy and cool conditions, and occasional rain or drizzle. This coastal system will weaken and move out to sea on Tuesday and improvement in the weather will begin to take place in the Mid-Atlantic region. High pressure builds in by the middle of the week and generates comfortably cool and dry conditions for much of the second half of the week.

Lots of players are on the field as we begin the weekend with one upper-level low over the Great Lakes that is dropping slowly to the southeast and a second wave of energy in the southern stream that is helping to spin up a surface low pressure system off the southeast US coast. In addition, there is a strong high-pressure system to our north that continues to shift slowly offshore as we begin the weekend. The combination of the high to the north and low to the south is already producing an onshore flow of air in the Mid-Atlantic region and this will persist for the next few days potentially leading to significant coastal flooding/beach erosion from Long Island-to-New Jersey-to-the Delmarva Peninsula. While there can be some heavy showers and strong wind gusts across inland areas during the next few days, rainfall amounts will be much more limited with the worst impact from this developing storm system confined to coastal sections.
