Area Forecast Discussion National Weather Service New York NY 753 AM EDT Tue Sep 29 2020

SYNOPSIS. A slow moving cold front will approach today, and pass through late tonight into Wednesday morning as a wave of low pressure develops along it. High pressure will build in Wednesday night through Thursday, with a cold front moving through Thursday night. Weak low pressure will develop along the frontal boundary on Friday and head northeast. After high pressure returns for the weekend, another frontal system may impact the area next Monday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Low clouds mainly across the interior and eastern Long Island will persist into this morning. Meanwhile a weak trough and upper level jet streak moving up the coast will bring an initial round of showers this afternoon, some of which could be moderate to locally heavy, and impacting mainly western sections of the area this afternoon. The cold front that will bring heavier rain tonight will only just be entering ern PA by late afternoon.

Afternoon clouds/precip should hold back high temps a little, and blended MOS with cooler model 2m temps, with highs in the lower and mid 70s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. A vigorous upper trough with the approaching cold front will be taking on a negative tilt tonight, and induce a wave of low pressure to develop along the front as it enters the area as well as a 70+ kt southerly LLJ. The LLJ will transport tropical moisture northward, with PW increasing to 1.75-2.00 inches. Model guidance in general agreement that a round of heavy showers will occur after midnight, but disagree somewhat on placement, with high-res CAM's focusing more on the lower Hudson Valley and SW CT, while latest NAM/GFS are a little farther east across NYC, Long Island, and CT. Either way, a widespread 1-2 inch rainfall is likely, with isolated totals over 3 inches possible in the heaviest rain bands. Urban and poor drainage flooding are the main threats, as antecedent conditions have been dry and flash flood guidance is quite high. Reintroduced chance thunder to the forecast as the LLJ should help destabilize the low levels and increase elevated CAPE.

Issued a wind advy for most of Long Island and southern CT for late tonight into early Wed morning as the LLJ passes overhead, with model guidance indicating potential a shallow mixed layer allowing 40-45 kt gusts to occur especially with heavier precip.

Winds will shift to WSW after cold fropa, with improving conditions from west to east through the day on Wed, and high temps in the upper 60s and lower 70s.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. Conds should be mainly dry Wed night into Thu, but confidence is not very high. Earlier model guidance had backed off on the idea of a second low impacting the area Wed night into Thu, but another approaching upper trough late Thu night into Fri may induce a wave of low pressure to develop along a frontal boundary over the Mid Atlantic region and bring showers late this week. NAM does this as early as daytime Thu and grids now have slight chance PoP to account for this possibility Thu into Thu night.

High pressure builds in for the weekend before another frontal boundary may impact the region next Monday. However, there is a great deal of uncertainty with this system and the potential for an area of low pressure to move up the East Coast.

As for temperatures, with an upper level trough over the area, and 850 hPa temperatures starting out at around 7 C on Thursday drop to between 4 to 7 C into the weekend and the beginning of next week, expect near normal temperatures on Thursday transitioning to seasonably cool by Friday and should continue into Monday.

AVIATION /12Z TUESDAY THROUGH SATURDAY/. A cold front approaches the east coast today through tonight bringing unsettled conditions late this evening into the overnight hours.

MVFR to IFR stratus should begin to wane this morning though KGON expected to have IFR much of the morning. Any lingering fog should dissipate as well. VFR conditions could be brief as afternoon showers are expected to promote MVFR ceilings for most of the afternoon into the evening.

Rain showers become more steady and relatively heavier tonight and overnight with widespread MVFR to IFR expected after 05Z.

Winds will generally be S near 10-15 kt for most of the day then increase to 15-20kts with gusts 25-30kts possible ahead of the cold front. Wind shear may also become an issue for the east most TAF sites during the overnight hours.

. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty . Timing of showers and gusts late this evening may need amendments.

OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY. Wednesday. MVFR/IFR with rain showers. Heavy rain possible early. LLWS early with S-SW winds 40-50 kt at 2kft. SW winds 10-15 kt with gusts 20-30 kt, highest east of NYC terminals and highest in the morning. Thursday. Mainly VFR. SW wind gusts 15-20 kt. Friday. MVFR possible with a chance of rain showers in the afternoon and evening. Otherwise, mainly VFR. Saturday. VFR.

MARINE. Ocean seas should remain in the 3-4 ft range today, with S flow increasing to 10-15 kt. Stronger S winds with an approaching cold front expected tonight, and have issued a gale warning for all waters except NY Harbor and the Western Sound, with wind gusts 35-40 kt expected overnight tonight, and ocean seas as high as 6-9 ft. Winds on the western Sound and Harbor should reach SCA criteria, with gusts 25-30 kt.

Seas will slowly diminish Wed into Thu, but 5-ft ocean seas could linger into daytime Thu.

HYDROLOGY. A slow moving frontal boundary and a wave of low pressure will bring significant rainfall from this afternoon into early Wednesday. Widespread rainfall of 1-2 inches with local totals over 3 inches are possible. Due to dry antecedent conditions, the relatively long duration of the event, and high flash flood guidance, no significant flooding is anticipated. Urban and and poor drainage flooding are the main threats.

Light to moderate rainfall is possible Friday into Friday night.
