High pressure will build in from the northwest through tonight. A slow moving warm front then approaches from the southwest Wednesday into Thursday. High pressure briefly builds in for Friday. A cold front moves through Saturday into Saturday night. High pressure builds in late Saturday night into Monday.

Near Term - Through Tonight
Forecast remains generally on track. Adjusted high temperatures up slightly to account for the rapidly warming BL which may overperform with highs similar to yesterday but not to the same extent.

A departing upper trough across the Northeast and an upper low lifting across the Central Plains will allow ridging between the two to build into the area through tonight. At the surface, high pressure ridging down across the Great Lakes will work in from the west. Expect another warm, dry day, but about 10 degrees cooler than the day before. Highs are expected to be in the mid and upper 60s to around 70 across the NYC metro. NW winds today may occasionally gusts 15 to 20 mph. Seabreezes should not get too far inland.

For tonight, clear skies and light northerly winds will allow for a cooler night than recent days, but still a few degrees above normal.

Short Term - Wednesday Through Thursday
Weakening low pressure lifts up through the Great Lakes on Wednesday and into south central Canada by Thursday. The associated warm front will approach from the SW during this time with increasing rain chances Wednesday afternoon and night due to deep-layered warm advection. The system is not deeply convective and lift is modest. Rainfall amounts are forecast to between 0.25 to 0.75", with the highest amounts at this time across the NYC/NJ metro and LI. The bulk of the rain looks to fall Wednesday night.

An easterly flow and chances of rain will drop highs on Wednesday about 5 to 10 degrees cooler than Tuesday, and this trend continues into Thursday. East winds ramp up Wednesday night into Thursday as the pressure gradient strengthens between the departing high and the warm front. Gusts potential is 20 to 30 mph, highest along the coast. A frontal wave developing along the warm front pushes off the Mid Atlantic coast on Thursday.

Long Term - Thursday Night Through Monday
The warm front weakens Thursday night as it moves into deep layered ridging and a weak low tracks east of the Mid-Atlantic. The low meanders off the mid-Atlantic coast on Friday with an inverted trough extending northward towards us. At the same time, a cold front approaches from the west. Most, if not all of the day will likely be dry, however, cannot rule out an afternoon shower especially north and west of New York City. A chance of showers then follows for the entire forecast area Friday night into Saturday with the cold front passing through.

High pressure then builds in from the west Saturday night through Monday, with dry conditions forecast through the period.

High temperatures through the period are expected to be within a few degrees of normal.

Wind and seas are forecast to remain below SCA (Small Craft Advisory) as high pressure builds in from the NW through tonight. A warm front approaches on Wednesday with a tightening pressure gradient between the front and departing high. There is the potential for SCA (Small Craft Advisory) conditions in an easterly flow late Wednesday night into Thursday. Gusts of 25 to 30 kt will be possible with seas on the ocean of 4 to 7 ft.

Winds diminish Thursday night into Friday, however a lingering swell with onshore flow may keep ocean seas above 5 ft through at least Friday morning. Sub- advisory conditions on all waters otherwise Friday afternoon through Saturday.

There is the potential for 0.25" to 0.75" of rainfall from Wednesday afternoon through Thursday afternoon. No hydrologic impacts are expected with this event.
