After mostly overcast day, with little rain yesterday, we’ve cleared for some more sunshine today. Temperatures are already in middle to upper 50s. The latest guidance shows 850mb temperatures 2C to 4C this afternoon. Which typically highs in upper 50s to lower 60s with sunshine. However, with north winds the airmasss today is very dry. Dewpoints will be in the upper 20s to lower 30s. This will allow temperatures to rise into the middle to upper 60s in most areas today. Even along the south-facing shores, where north winds will hold back sea-breezes this afternoon. Some spots may even get into the lower 70s.

High pressure moving move off the coast, will cause light winds to turn more east to southeast tonight and tomorrow. This will result in cooler higher temperatures in the upper 50s to lower 60s. But it will still be a nice day with mostly sunny skies. High pressure at the surface and aloft will keep clouds from forming, most of the day. Clouds will increase tomorrow night and as weak shortwave trough arrives from the west. Mostly cloudy skies are expected on Friday with some scattered showers possible.

A cold front will move across the area early Saturday. But cooler air will be lagging way behind this front. West to northwest downslope winds will cause skies to clear and temperatures to jumping into the lower to middle 70s for much of the region. West-northwest winds should sea-breezes from moving inland. This could be the warmest day so far for Northeast New Jersey, New York City and Long Island. On Sunday, center of high pressure will move just off the coast. This will cause winds to turn east to southeast again keep temperatures a little cooler than Sunday. However, it remain close to the area to keep us under sunny skies for most of the day.

Early next week, the northern and southern stream energy will phase into large upper-level low near the Great Lakes region. Several waves of energy rotating around this low will keep us in unsettled weather pattern through for much of next week, with temperatures likely averaging near or below normal. An occluded front with a south to southeast flow of Atlantic moisture, will bring some rain on Monday. Some of the model guidance also a shower secondary or triple-point low developing near the area Monday. This could enhance a period of very heavy rain and gusty winds in our area. This is only a possibility at this point. A blog post will be models later if models continue to show this threat today.
