Area Forecast Discussion National Weather Service New York NY 1239pm EST Thu Jan 23 2025 Synopsis High pressure continues to weaken into tonight as low pressure passes offshore late in the day and tonight. Another high builds into the region Friday, and remains Saturday, shifting south Saturday night. A cold front is expected to move across the region late in the weekend, followed by another cold front Tuesday into Wednesday. Near Term - Through Tonight Warm advection continues this afternoon allowing temperatures to moderate from the last few days. There has even been some flurries reported across eastern Long Island and southeastern CT. Have added in isolated flurries for the next few hours. No accumulation expected given the flurries are coming from a shallow cloud layer and there is limited snow growth based on very light reflectivity. Otherwise, high pressure continues to weaken this afternoon. Highs will reach the middle and upper 20s for most with low 30s closer to the CT and LI coasts. Most spots will stay below freezing, but a few locations on eastern Long Island may touch or briefly exceed freezing for the first time since Sunday night. A southern stream low pressure will pass well offshore tonight. Any moisture with this system looks to stay well to our east with mostly clear skies overhead. Lows will range from around 10 degrees inland to the middle and upper teens elsewhere. Short Term - Friday Through Saturday Upper ridging moves into the region during Friday and remains Saturday, while surface high pressure builds into the region. With another upper trough moving into the northeast Saturday night the surface high gets suppressed southward. However, dry conditions will remain with temperatures remaining below normal levels. Once again a blend of the deterministic and MOS guidance was used. Long Term - Saturday Night Through Wednesday High pressure remains over the region this Saturday night and Sunday. Temperatures do warm a bit for Sunday with highs in the middle and upper 30s, to near 40 along the coast. The high slides offshore allowing a series of upper level troughs and associated surface cold fronts to push across the region. The first will be Sunday night into Monday, followed by another Tuesday night into Wednesday. Each of these systems should bring some cloud cover to the area, however there is not much moisture to work with, so many of these fronts will push across the area dry. High temperatures Monday and Tuesday will be in the 30s. A cold front will bring a re-enforcing shot of cold air for Wednesday and Thursday with highs remaining in the 30s. Marine A weak pressure gradient will lead to winds and seas below SCA levels through Saturday night. Small craft conditions are expected to return for Sunday and continue for a large portion of next week as a series of cold fronts move across the area. Hydrology No hydrologic issues expected through the middle of next week. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None. Marine None. |
