Mother’s Day weekend here in NYC unfortunately looks to be quite rainy. We start off with the potential for rain later today. Saturday is shaping up to be the sole dry day with high pressure briefly building before giving way to a prolonged period of wet weather Sunday and Monday. So, if you’re making any outdoor plans for mom, consider bumping them up to Saturday!

Rest of today – cloudy, with temperatures around 70°F. We will sit in the warm sector of an elongated low centered over western Quebec as a warm front has already passed overhead. This will allow plenty of mild, moist air to stream northward with southerly winds ahead of the trailing a cold front associated with this low. This cold front will serve as the trigger for some showers and thunderstorms later this evening as it swings through. Overnight lows behind this cold front in the mid-50s.

Saturday – high pressure briefly builds in during the day. This will give us the best weather of the weekend with mostly sunny conditions and seasonable high temperatures in the upper-60s. Ideal weather for any outdoor activities. This nice weather doesn’t last with clouds building into the overnight hours and low temperatures dipping to the low-50s

Sunday – another storm system approaches from the south. A warm front at the leading edge of this storm seems likely to stall out. This will bring a prolonged period of chances for showers, cloudy skies, and cooler temperatures with easterly onshore winds. High temperatures in the mid-50s. Overnight lows quite cool in the upper-40s as rain chances continue.

Monday – a coastal low forms along the frontal boundary mentioned above. At this time, it appears this coastal low tracks close enough to make Monday another rainy day with cool temperatures, highs in the mid-50s, 10-15°F below normal for this time of year. Overnight lows looking even colder than Sunday if prolonged rain and a northeasterly wind flow materializes with this coastal low, current forecasts pointing to the mid-40s.
