The North Atlantic Oscillation (NAO) is a great way to spot long term weather patterns. Whenever NAO is negative, temperatures will stay near or below normal - like in February and early March. Whenever NAO is neutral or positive, then the Mid-Atlantic will be generally warmer than normal - like late March and all of this month. All indications point to NAO diving back negative by the middle and end of this month. This mean that temps will return to near or below average to finish the month. It could also be the return of a stormy weather pattern. This is something we will be tracking over the next several days and will have more updates soon!
