WHAT HAS CHANGED

No notable changes with this update.

KEY MESSAGES

1) A noticeable warmup begins today.

2) The warmup becomes more widespread into mid week, peaking Wednesday into Thursday.

KEY MESSAGE 2

500 mb height will remain fairly steady state, with 570dm+ likely to remain in place through Thursday. The only question is how much of a southerly component to the sfc winds will take place and for how much of the region. For Tuesday and Wednesday a W to WSW wind should prevail through midday across the entire region. This will allow temperatures to climb quickly both days, even for most coastal sections. Then later during the afternoon hours a sea breeze should develop in response to the rapid warming and the winds at the sfc will become more southerly, and therefore temperatures should fall later in the day for coastal sections, but not before temperatures climb well above normal. Daytime maxes by Wednesday likely get into the upper 80s and maybe even touching 90 in the warmest locations across metro NE NJ. This is supported by 850 mb temperature forecast of 15-16 C. On a side note, the chance of showers and any convection appear to be low through mid week. Some CAM guidance is suggestive of a chance / slight chance of showers and a few thunderstorms late Tuesday into Tuesday evening. However, the best forcing looks to remain north of the region, thus the chances of convection and any impactful thunderstorm activity appear to be rather low at this time.

OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY

Tuesday through Friday: Mainly VFR but with chance of afternoon and evening showers/tstms each day, mainly NW of the NYC metros, with brief flight cat reduction to MVFR. SW winds could gusts 15-20kt each afternoon Tue-Thu as well.

MARINE

Small craft conditions are expected across all waters today with a gusty WSW to SW flow regime. Later tonight small craft conditions subside, first for the non-ocean waters during the evening, then later at night across the western ocean. By Tuesday AM sub advisory conditions will prevail across all waters. By late in the afternoon and early evening marginal small craft conditions are expected for the ocean and the south shore bays of LI, otherwise sub advisory conditions are expected. Marginal small craft conditions are expected to develop once again for the same locations late Wednesday and late Thursday in association with sea breeze development and a diurnal increase in southerly flow. Sub advisory conditions are anticipated Friday with ocean seas primarily around 3 ft.
