High pressure has drifted eastward off the coast, allowing for moisture to come in off the Atlantic Ocean as winds turn east/southeast through the first half of Sunday. With the influx of moisture, clouds will likely be around for much of the day. However, we should still be above average for this time of year with highs reaching the mid 70s. Overall, the day should feel warm and even slightly humid as we head into the afternoon.
We’ve been watching a stationary front that’s sliced across the Mid-Atlantic, responsible for the wet weather near Washington DC and New York City. Through Sunday, that boundary will start to lift north as a warm front, or the leading edge to a warm and humid air mass. While that air mass won’t make it into central New York on Sunday, the front will be close enough that we can’t rule out a shower or thunderstorm. They will likely be spotty in nature.
The warm front will move to our north Monday and southerly winds will bring in the more humid air for central New York. That additional moisture will mean we still run the risk of a shower or thunderstorm. With that warm front to our north we will take a shot of getting into the low 80s, which would make it the warmest day we’ve had so far in 2013.
Beyond Monday our weather revolves where that front ends up. We think it may not be too far away from central New York Tuesday through Thursday. With it close by we will have extra cloud cover and an increased chance for showers and thunderstorms through the middle of the work week. For that reason we are going to hold temperatures during the midweek in the 70s (still above normal for mid May). If it becomes clearer that this front will stay far enough to our north then we will likely have to raise those temperatures into the 80s.
A cold front will sweep this warm and humid air mass out of central New York late in the upcoming week.
