A frontal system brings periods of heavy rain tonight and a gusty Friday as a deepening low departs northeast. Widespread 1.5–2.5" rainfall, gusts to 40–45 mph, gale conditions on coastal waters, and minor coastal flooding near high tides. Best outdoor windows arrive Saturday afternoon and Sunday.

A compact but potent frontal system has already carved its way across the region today, and the picture for the next week is one of an active transition: bands of moderate to locally heavy rain tonight, a strengthening low exiting into New England and eastern Canada Friday into Saturday, then a drier and seasonably cool period through midweek with one more frontal ripple possible Monday night into Tuesday. I’ll walk you through the meteorology in straightforward terms and give practical, location-aware advice for outdoor adventurers in the New York metro, Long Island, and coastal Connecticut.
The near-term: expect the main band of rain to continue sliding eastward this evening. The line has produced locally heavy downpours and has already diminished a bit in overall intensity, but a surge of convective showers and wrap-around rain is expected tonight as the low’s triple point lifts overhead. Widespread totals of roughly 1.5–2.5 inches are likely by morning, with some pockets up to 3–4 inches. That means lingering saturated ground, ponding on streets and low-lying trails, and nuisance flooding in urban low spots and back bays. Winds will be variable tonight but turn westerly after midnight; gusts up to ~35 mph are possible tonight with stronger gusts coming Friday.
Friday into Saturday: the surface low will deepen as it departs to our northeast, tightening the pressure gradient. That translates to a gusty Friday — sustained west winds near 20–30 mph with peak gusts to 40–45 mph, especially near the coast and around NYC. A Wind Advisory is in effect from noon Friday into Friday night for the entire area. Conditions will still be breezy Saturday with gusts 25–30 mph near the coast and metro; winds ease late Saturday evening. Temperatures are modest — highs in the mid-50s both Friday and Saturday, then overnight lows cooling into the 30s away from the immediate coast Saturday night (frost possible inland).
Coastal and marine impacts: gales have been observed across the bays and eastern ocean waters and are expected to re-establish, particularly Friday into Saturday. Gale Warnings are in effect for many waters. Expect steep breaking waves (5–7 ft) on the oceanfront and the potential for beach erosion and inundation around high tides — the afternoon tide this evening already produced minor coastal flooding in vulnerable bays and lower NY Harbor locations. Another pulse of locally minor coastal flooding is possible with the Friday morning high tide on south shore bays where water may not have fully receded.
Hydrology: with the 1.5–2.5" areal average and higher localized amounts, urban and poor-drainage areas will see nuisance flooding. Trails with poor drainage and riverbanks could be slippery and higher than normal. Flash flooding is not the widespread expectation, but localized rapid rises are possible in small streams near heavier convective bands.
Aviation and visibility: many terminals have been in MVFR/IFR through the afternoon with pockets of heavier rain and low ceilings; conditions should gradually improve behind the eastward-moving band to MVFR, then VFR later Friday. Marine visibility will likewise be reduced in heavy showers and fog in sheltered bays.
Longer range (Sunday–midweek): a more settled, seasonable airmass builds in behind Friday’s system. Sunday looks mostly sunny and cool with light winds, though inland lows could dip into the mid-30s and produce frost in protected valleys. Monday could be slightly milder as high pressure moves offshore; a weak cold front may brush the area Monday night and early Tuesday with low chance showers. Overall confidence in the weekend through midweek pattern is moderate to high.
What this means for outdoor adventures: tonight and Friday morning are not good for exposed outdoor plans — heavy showers and gusty winds will make paddling, shore fishing, beach access, and exposed ridge hiking unsafe. Friday afternoon into Friday night is the peak wind threat — secure gear, avoid shoreline ledges and exposed bridges, and avoid boating in open waters. Saturday afternoon offers improving conditions for outdoor pursuits, though coastal winds remain breezy. Sunday is the best full-day window for trail hiking, road cycling, photography, and paddle outings in more sheltered bays if you’re mindful of cooler overnight temps and possible frost inland. Keep an eye on tides and recent erosion before planning beach walks on eastern Long Island ocean beaches.
Bottom line: tonight brings the bulk of the rain and flooding nuisance; Friday is the wind event (Wind Advisory), especially problematic for coastal and high-profile travel; Saturday improves but stays breezy; Sunday into midweek is the more dependable outdoor window. If you have flexible plans, defer exposed watercraft and oceanfront activities until Saturday afternoon or Sunday, and expect slick trails, damp roots, and localized ponding into early next week.

Active storm tonight with heavy rain and saturated ground reduces suitability. Friday’s strong winds and marine gales limit exposed adventures. Saturday afternoon and Sunday provide much better windows for many activities, though pockets of risk (slick trails, coastal surge) remain.
Favours inland hiking, trail running, and photography on Sunday and Saturday afternoon in sheltered areas.
Not good for ocean kayaking, open-water boating, or exposed ridge travel tonight and Friday due to heavy rain and gusty winds.
Caution for road cycling Friday — crosswinds and fallen debris possible; better on calmer Sunday.
A cold frontal system and associated low will pass through tonight into Friday, then rapidly deepen and move into New England and eastern Canada. Strong west to northwest pressure gradient follows Friday into Saturday producing gusty winds and marine gales, then high pressure builds for a drier, seasonable weekend into midweek with only a small chance of showers late Monday into Tuesday.

Tonight’s heavy rain and Friday’s gales will make open-water paddling hazardous; calmer waters and lighter winds return Sunday after high pressure builds.
Sunday late morning to mid-afternoon
Avoid oceanfront launches until surf subsides; check for debris and runoff near river mouths after heavy rain.
Wind gusts ease Saturday afternoon; Sunday has the most stable, seasonable air with clearer skies and good light for photos.
Saturday afternoon and Sunday all day
Trail roots will be slick from rain—use trekking poles and wear good-grip footwear. Expect chilly mornings and potential frost inland.
Breaking waves (5–7 ft) and minor coastal flooding around high tide are possible tonight and Friday; shoreline conditions improve late Saturday with decreased surge.
Late Saturday afternoon when winds relax
Watch for dune erosion and avoid low-lying back-bays at high tide; observe posted beach warnings.
Friday’s strong gusts favor sheltered routes or postponement; Sunday is a much better day for road cycling with lighter winds and cooler temps.
Avoid Friday midday–evening; Sunday is ideal
Expect crosswinds and possible debris Friday; secure loose gear and lights, and ride defensively.
Trails will be slick after heavy downpours. Use a steady cadence, avoid wet rock edges, and consider traction devices for steep descents.
Small streams and boggy sections will be fuller than normal. Bring gaiters and quick-drying socks to stay comfortable.
Waterproof cases or drybags are recommended for phones, cameras, and first-aid kits during tonight’s rain and any residual showers.
Friday’s gusts (Wind Advisory) can topple lightweight shelters and blow debris. Secure tents and avoid exposed ridge camping.
Lightweight, breathable rain shell to stay dry during lingering showers and heavy downpours.
Midweight base layer and insulating mid-layer for chilly mornings and windy ridge exposures.
Helps with balance on muddy, root-filled trails after heavy rain.
Protect electronics, first aid kit, and spare clothing from rain and splashes during paddling or shore walks.
Useful on frosty surfaces early in the morning or late-night climbs that retain ice.
For urban cyclists or anyone near roadways during gusty conditions and lower visibility.
