Frontal rain looks to be breaking up as it heads east

1.5 so far at my station

Comfortable night. Temp 73 DP 38. Take advantage of the low dews. They won’t last too long.

Down to 29.04 or 983 millibars at my station. Impressive for April 30th. Winds going to be gusting 20-30 mph once the center passes. Atlantic City gusting to 35 out of the west.

Down to 29.07 with 3.5 inches of rain for the day so far and a storm total of 5.55

Looks like the low is off the Delaware coast. My barometer is showing 29.11. Atlantic City at the 10pm obs down to 29.05 (approx 984 millibars) Not much wind though. Probably because there is no high pressure nearby.

My barometer is down to 29.25 and still falling rapidly.

Had a rate of 7.02 inches per hour with that deluge a little while ago. Total for the day so far 2.76. Storm total 4.82 so far.

1.98 total at my station.

Just over 1.5 inches at my station so far.

Just over 2 inches at my station. Much needed.

Up to 69 at my station on a light ENE wind. Sun shining through the clouds.

Looks like the intensity is decreasing somewhat as the sun sets

89 dew of 49 by me at the north "inland" part of Sheepshead Bay Brooklyn

Wind just flipped to SSW and temp is down to 68 now Down to 60 as of 4:10pm on a SE wind

Up to 77 here now with more sun shining through the overcast

Up to 74 now.

Up to 72 with mostly cloudy skies.

.45 of rain so far here at my station

OKX sticking with a mostly rain scenario at the coast. From this morning’s AFD: By Monday night, the upper level low forces the coastal low to rapidly deepen as it passes near the 40N 70 W benchmark. Some model guidance actually has a separate area of low pressure develop over the area in the apex of the inverted trough. This will result in widespread moderate to locally heavy precipitation Monday night into early Tuesday morning. Rain along the coast may be heavy at times through the night. This is likely when a bulk of the precipitation from the event falls with coastal areas possibly seeing as much as 1.5 inches of rainfall from sunset Monday to sunrise Tuesday. There remains a considerable amount of uncertainty as to how the transition to snowfall occurs of the northwestern fringe of the cyclone. The thinking is that mainly rain Monday evening transitions to a rain/snow mix and then primarily snow for the Lower Hudson Valley and portions of interior NE NJ and W Connecticut. As strengthening NW winds advect marginally cool air from the north, the rain/snow transition may make some southward progress toward daybreak Tuesday. There remains a possibility that precipitation for much of the area will be a mix of rain and snow by Tuesday morning and through much of the day on Tuesday with temperatures expected to be in the middle 30s for the coastal areas. As precipitation lightens Tuesday afternoon and evening, the upper level trough passes over the area allowing for a more favorable profile for plain snow for much of the area. Any accumulations at this point should be minimal.

I just passed JFK. It’s a snow/rain mix. Temp down to 36

From OKX evening AFD: NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... Guidance has converged for the weak and quick moving low pressure system that will be moving out of the upper midwest and passing to the south of the region tonight. The trend has been for a colder and slightly farther southern track, with mainly snow across the area late this evening and overnight. There may be a brief rain/snow mix at the onset, and transition to snow as the atmospheric column cools. Precipitation will be generally light with weak upper support with a flat and broad shortwave moving through the area. Timing of the precipitation is also rather consistent with onset around 1000 PM and ending by 500 AM, with the bulk falling in a 3 hour window midnight to 300 AM. The onset may be delayed as the lower layers are dry, and will have to be overcome. The band of snowfall is also rather narrow, with a sharp gradient of no snow to 1 to 1 1/2 inches of snowfall. And locations to the northeast and east likely see no to very little precipitation. Therefore, any minor shift in the track of the low will have impacts to where the heaviest snow will occur. With the ending time of snow toward Tuesday morning, the morning commute will be impacted and this is highlighted in the hazardous weather outlook (HWOOKX).
