Wednesday, everything changes ?
The day will start in the mid- to upper 40s but will quickly heat up. Temperatures will hit the mid-50s around 11 a.m. and the 60s by 1 p.m.
The high will be only a few degrees below normal.
Thursday, Friday and the weekend ?
It will finally feel like May.
The expected highs on Thursday and Friday, in the upper 60s, would be just slightly below average. Saturday and Sunday should be in the low 70s, which is on par for this time of year.
What can explain all of this?
Cold air moved in and, in my unofficial terminology, it has overstayed its welcome.
Or as Melissa Di Spigna, a National Weather Service meteorologist, told me, “It’s a very, very slow-moving pressure system.” That system, she continued, gave “us cloudier conditions, breezier conditions and colder air.”
“It’s finally supposed to move east of us on Wednesday night,” Ms. Di Spigna added. So, Wednesday “could be a little showery, off and on.”
What’s the big picture?
This May has been colder and wetter than usual.
So far this month, New York City’s temperature has been, on average, about one degree below normal, Ms. Di Spigna said.
