Area Forecast Discussion National Weather Service New York NY 652 AM EDT Tue May 26 2020

SYNOPSIS. Offshore high pressure will continue ridging across the area through Thursday. A slow moving cold front approaches Friday and moves through Saturday. High pressure returns Sunday into early next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. The fog and stratus burns off by late morning. A model consensus was used for burnoff time, but this is always tricky especially near the coast. The stlt fog product shows extensive fog over the ocean. It is entirely possible that a fog bank sets out there today, possibly even hugging the Long Island coast based on the sly llvl flow.

The onshore flow will limit the potential warmth today, with highs ranging from the lwr 80s in the nwrn interior to upr 60s along the oceanfront. The NBM was followed with some tweaks, particularly invof Montauk where the numbers seemed too low based on the MOS. If the fog hangs in however this will be a major bust as temps could struggle to even get to 60.

There is a moderate rip current risk today.

SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/. More fog is expected tngt. There appears to be more dry air aloft which could tip the scales towards more widespread dense. Patchy dense has been included in the fcst for now. A similar burnoff challenge is expected for Wed, and to account for the uncertainty a model blend was used. For temps, went closer to a MAV/MET blend which brought the n shore of Long Island up and the sern CT coast down. Elsewhere it was very similar to the NBM. The NBM was used for the overnight temps with some manual adjustments.

There is a moderate rip current risk for Wed.

LONG TERM /THURSDAY THROUGH MONDAY/. The core of the upper ridge will begin to break down on Thursday and shift over the Western Atlantic. However, the surface ridge looks to remain in tact, which will likely keep much of the region dry through Thursday. Patchy fog and low stratus are also likely Thu morning with a continued onshore flow and warm air moving over ocean temperatures in the lower 50s. Any stratus and fog likely diminish with daytime heating, but it could linger near the coast. The ridging will boost temperatures away from the immediate coast into the upper 70s to near 80 Thursday. Temperatures closer to the coast will be held down in the lower to middle 70s and some places more exposed to the onshore flow could stay in the 60s. Temperatures could also be held down if stratus and/or fog hang on longer. There could be a few showers that traverse around the periphery of the ridge as it breaks down Thursday, mainly N and W of NYC.

The upper ridge continues to break down Thursday night into Friday with a more significant upper short wave trough digging into the Great Lakes and southeast. There may be some vort energy traversing around the ridge from the southeast Thursday night into Friday morning which could bring some higher probability of showers. Otherwise, the main area of forcing will be with the shortwave and its associated cold front, which models have been slowing down over the last several runs. There may be a prefrontal trough developing to our NW Friday with some enhanced convection, but the highest probabilities for showers and possible thunderstorms may occur Friday night into the first half of Saturday with the actual cold front. Forecaster confidence is low regarding the timing of the front, so have continued to go with chance probabilities. Have increased them on Saturday due to the trend for a slower frontal passage.

Conditions should improve late Saturday into Saturday night as the upper trough moves over the Eastern States. High pressure builds down out of Southern Canada for Sunday into early next week with dry conditions expected.

Conditions will become increasingly more humid into the end of the week. The timing of the cold front will ultimately determine how warm temperatures reach Friday into Saturday. Highs should remain cooler near the immediate coast, in the lower to middle 70s, with temperatures in the upper 70s and lower 80s away from the coast. Temperatures trend cooler and possibly below normal Sunday into early next week.

AVIATION /12Z TUESDAY THROUGH SATURDAY/. Offshore high pressure will continue to ridge across the area the next several days. This will keep the terminals under a weak, mainly moist onshore flow.

Widespread LIFR/VLIFR conditions this morning will gradually improve to VFR by late morning. The improvement looks to be quicker today than what we saw yesterday. Still though, there is some uncertainty with the timing. There is then a good potential for a repeat performance tonight with not much change in the airmass.

Light and variable winds become E-SE at less than 10 kt this morning, and then more southerly in the afternoon.

OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY. Wednesday-Thursday. VFR. Chance IFR with areas of fog during the overnights into early morning hours each day. Thursday night-Saturday. MVFR possible. A Chance of showers and thunderstorms.

MARINE. Areas of dense fog can be expected thru this mrng. There is a chance the fog could persist all day, especially on the ocean. Additional fog development is likely tngt into Wed. Winds and seas however will remain blw sca lvls thru Wed.

High pressure over the Western Atlantic will keep winds and seas below SCA levels Thursday. More fog is possible Wed ngt and Thursday morning. Winds increase ahead of a cold front on Friday and could come close to 25 kt on the ocean. Ocean seas may also build to around 5 ft. Winds should gradually weaken Friday night into Saturday, but 5 ft ocean seas may persist into the first half of the weekend.

HYDROLOGY. No significant hydrologic impacts are expected through Thursday. Showers and thunderstorms are are possible Friday into Saturday with a chance for minor urban and poor drainage flooding.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . Dense Fog Advisory until 10 AM EDT this morning for ANZ330-335- 338-340-345-350-353-355.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
