WHAT HAS CHANGED

No significant changes.

KEY MESSAGES

1) Temperatures will remain above normal through Friday.

2) Showers and thunderstorms possible tonight and Friday, and again Sunday afternoon and evening.

3) A cold frontal passage on Sunday will usher in much colder weather for the beginning of next week.

KEY MESSAGE 3

A stronger cold front will move across the region on Sunday, bringing another round of showers and embedded thunderstorms.

Good cold air advection kicks in on a NW flow behind the front and temperatures quickly fall by late in the evening and overnight. Any lingering areas of rain may mix with some sleet or snow as the precipitation comes to an end. Lows Sunday night drop into the 30s, except near 40 in the NYC metro area.

The cold pool aloft builds in Mon with 1000-500mb thicknesses around 520dam. The steep lapse rates should allow for at least isold-sct shwrs, possibly mixed with snow or ice pellets. The NBM pops may be a bit too low. Temperatures Monday night will range from the upper 20s to middle 30s.

Friday: Chance of showers, mainly in the afternoon and early evening. MVFR or lower conditions possible, especially at night.

Saturday: Chance of MVFR ceilings.

Sunday: MVFR or lower conditions possible. Showers likely. W winds gusts 20 kt in the afternoon and evening.
