Marine Weather and Tide Forecast for Highland, NY

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
Periods of light rain continue through tonight across eastern New York and western New England as we're inbetween two surface low pressure systems. One located off the Atlantic Coast that's contributing to the steady rainfall over western New England and another located over the Great Lakes region contributing to the scattered rain showers over eastern New York. Both continue to move north and east tonight contributing to the continuation of rain showers tonight. For southern Vermont, snowfall amounts continue to trend down for less than half of an inch for locations above 2000 feet and the highest peaks up to one inch.
While snowflakes could fly tonight for locations as low as 1500 feet as temperatures hover below 36 degrees, it'll be mostly a cold rain with a brief period between 2 AM and 5 AM before sunrise for a mix of rain and snow. Temperatures continue to remain cool tonight with lows in the 30s and 40s.

SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/
Lingering light rain showers are in store to begin Memorial Day weekend as a surface low pressure system heads north and east away from eastern New York and western New England. The Mid-Hudson Valley could be missed from the precipitation chances and be mostly to partly cloudy for Saturday. High temperatures tomorrow range in the 40s for the southern Adirondacks and southern Greens while elsewhere should range in the 50s. The highest peaks of the southern Adirondacks could see Saturday morning a mix of rain and snow showers, but latest probabilities for early morning showers are less than 30 percent. Low temperatures Saturday morning range in the 30s and 40s. One more chilly evening Saturday into Sunday morning with temperatures ranging in the upper 30s and 40s.

LONG TERM /SUNDAY THROUGH THURSDAY/
Key Message:

- Return to seasonal temperatures begins Monday (60s and 70s)

Discussion: While low chances (less than 30 percent) for daily light rain showers continue Sunday through Wednesday morning due to multiple upper level shortwave troughs moving through, a period of dry conditions are favored for the end of Memorial Day weekend during the morning and early afternoon hours.
Temperatures finally begin a warming trend Sunday with highs ranging in the 50s and 60s. We warm up into the 60s and 70s for Monday into midweek. Wednesday begins the uncertainty of precipitation as an upper level low could move in and bring higher chances (40-60 percent) for rain shower activity to eastern New York and western New England. But the track could shift this far out in the forecast period with newer forecast model guidance and forecast confidence on exactly who sees a rain shower for Wednesday and beyond is low (less than 30%).

AVIATION /20Z THURSDAY THROUGH TUESDAY/
A large upper level through remains in place over the region while a surface low pressure area continues to impact eastern New England. The moist cyclonic flow in place will continue to allow for widespread clouds across the region for the rest of the day on Thursday into tonight. A few showers are possible through the rest of the day, especially near KPSF, although any precip is fairly light and rather brief, with limited impact on visibility. However, ceilings will remain fairly low for most sites. While KGFL may see some VFR ceilings through the late afternoon hours, most sites will see MVFR ceilings around 1500-3000 ft through the rest of the day on Thursday. Northeast winds will be around 10 kts, with a few higher gusts at times this afternoon, but they will start to diminish for tonight.

For tonight, MVFR ceilings are expected for all sites, with bkn- ovc cigs around 1500-2500 ft. At this point, ceilings should remain above IFR thresholds. A light breeze should help prevent much mist from developing, although if winds go lighter or calm, some brief mist/fog cannot be ruled out for the late night hours.

On Friday, flying conditions will continue to be MVFR. More showers and even a steadier rainfall is expected by the afternoon hours, with ceilings will around 1500-3000 ft for most terminals. Surface winds will be fairly light on Friday.
