There's a bit of a chill, temperature wise. However, warmer air will arrive late Tuesday afternoon, and it will be nicely warm by late Thursday evening.
However, a cold front will arrive Thursday night, showers may pop up Friday, and Shabbat will likely be rainy.
The cold air will last into Monday of next week. It should warm up a bit towards the end of next week, but Pesach's weather looks to be more of the same. Neither spring or winter, and no real rain either.
