New Yorkers rolled out of bed to blue skies and almost-summer warmth on Wednesday, April 15, with temperatures already near 69°F and the city on track to hit the low 80s by afternoon. The sticky, early-season heat is expected to hang on through Friday before a strong cold front moves in Sunday and sends temperatures tumbling.
Afternoon Storm Risk
Mostly sunny skies will dominate much of Wednesday, but a slight risk of showers and isolated thunderstorms creeps in after 5 p.m., with the highest odds late in the afternoon and into the evening. Any storm that does pop up could dump a quick quarter to half inch of rain in a brief downpour. Southwest winds of about 6 to 13 mph will add to the warm feel.
The National Weather Service is keeping rain chances at only 20 to 30 percent for the city and, for now, has no watches or warnings posted.
Heat Through Friday
Highs are expected to reach around 83°F on Wednesday, dip only slightly to about 82°F on Thursday, and then settle into the middle 70s on Friday, all well above what is typical for mid-April. Early mornings will offer the most comfortable window for outdoor plans. By midafternoon, the stronger sun and humidity could make it feel muggy, so anyone staying outside for more than a quick errand should plan on water, shade, or both.
Weekend Turnaround
On Sunday, a strong cold front is forecast to sweep through the region, bringing a better chance of steadier showers and thunderstorms. Behind it, temperatures are expected to drop quickly Sunday night into Monday, with lows falling into the 40s.
Coastal waters and small craft could see higher winds and rougher seas from late Sunday into Monday, so boaters and anyone planning time along the waterfront should keep checking updated forecasts.
Plan Ahead
If you have evening events on Wednesday or outdoor plans later in the week, it is smart to have a backup option. Any thunderstorm that develops should be brief, but it could send people scrambling for cover and cause some spotty delays for the evening commute.

Bottom line: expect warm and humid conditions through Friday with scattered late-day storm chances, then a noticeable cooldown after Sunday. Sunscreen by day and an umbrella by night would not be a bad combo.
