Today is expected to have high temperatures in the upper 50s to 60s along the immediate coast, in the upper 60s to lower 70s not too far from the coast including NYC, in the lower to mid 70s for the immediate north and west suburbs of NYC, and in the mid to upper 70s in the interior.
Tomorrow should have at least the same temperatures, though Sunday should be warmer for the New York City area, with highs in the lower to mid 60s along the coast, and in the lower to mid 70s for NYC, and in the mid to upper 70s for the north and western suburbs. The interior will be slightly colder on Sunday, with highs in the mid 70s.
Monday To Wednesday: Some Rain, Then Warmth
While Monday should still be relatively warm, with high temperatures in the lower 70s away from the coast, Tuesday should be different. An approaching front is expected to bring light rain showers to the area on Thursday afternoon and Thursday night, though only light rain amounts are expected, less than 0.1 to 0.2 inch.
This front is then pushed northward by a developing system, which brings much warmer temperatures to the area on Wednesday. While the immediate coast should not warm up as much, inland areas have the potential to reach the upper 70s to potentially 80 degrees.
Thursday And Friday: Rain And Thunderstorms Possible
By Thursday, the cold front starts to approach the area. While high temperatures should still be warm, in the upper 60s to lower 70s, rain is expected to start approaching the area. There is still uncertainty on the exact time the cold front moves through, though it should be sometime between Thursday and Friday. At this time, I am expecting the cold front to move through on Thursday night to Friday morning, with periods of rain and thunderstorms. More details can be found in the Stormy Weather Outlook page, where a blue alert has been issued for this storm (Less than 30% chance of significant rain or storms).
