Area Forecast Discussion National Weather Service New York NY 354 AM EDT Wed Jul 15 2020

SYNOPSIS. High pressure builds in from the Northeast today and begins to shift east on Thursday. The next frontal system will affect the region Thursday night through Friday night. Weak high pressure will then be in place for the upcoming weekend. Another frontal system may impact the region for the beginning of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. High pressure builds in from the NE at the surface while a ridge axis aloft approaches from the west. Moisture will be confined to mostly at 850mb and lower as it shifts generally east to west through the day with an onshore flow. Variable cloudiness adds some uncertainty to the high temperature forecast, but based on 900mb temperatures near 17C, leaned towards the warmer guidance.

There is a moderate risk for the development of rip currents at the ocean beaches today.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/. High pressure remains centered to our northeast tonight. The low level winds will remain onshore and result in partly to mostly cloudy conditions.

Mid level ridge axis shifts through on Thursday, and combined with the surface high, should keep us dry through the daytime hours of Thursday. In spite of the ridge axis shifting through, the boundary layer cools as winds through the mixed layer shift more SE with a stronger influence from the ocean. The top of the mixed layer (near 900mb) will be around 15C. High temperatures for the most part expected to be a couple degrees cooler than today.

There is a moderate risk for the development of rip currents at the ocean beaches Thursday.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. The 500mb flow flattens Thursday night with the passage of a shortwave to our north, where the best lift will be. Still, weak 850mb theta-e ridging and moisture flux convergence occurs with signs of isentropic lift ahead of a weak warm front. Will go with low chances of showers and thunderstorms for parts of the forecast area.

The 500mb flow becomes slightly cyclonic on Friday with indications of a weak surface cold front approaching, and passing through during the night. Stronger moisture convergence and building instability with perhaps the help of upper jet streak lift increase the chances of showers and thunderstorms for Friday and Friday night. Will cap PoPs at 50% for now. Highs on Friday returning closer to normal.

The frontal boundary could stall nearby to our south Saturday morning, but models agree on weak ridging at the surface and aloft, helping to dissipate the front. Will remain with a dry forecast on Saturday. The ridge axis aloft flattens on Sunday, but it still appears at this point we have a good chance of dry weather through the daytime. Temperatures this weekend heat up with models showing 850mb temps at 18-19C on Saturday and around 20C on Sunday. This would lead to highs 90-95 away from south-facing shores for Saturday. Will go with highs in the mid 90s for the typically warmest areas for Sunday, but may need to adjust this upward a little if models continue to show 850 mb temps around 20C. Progged boundary layer dewpoints would allow for some mixing out of surface dewpoints both days, but heat indices both days would reach heat advisory levels.

A frontal boundary moving into the region Monday and Tuesday may affect high temperatures for Monday. And any storms that develop may be more across the northern tier, along the northern periphery of the ridge. A weak trough remains into Tuesday along with a surface frontal boundary. And with energy moving through the flow chances of precipitation will remain Tuesday.

AVIATION /08Z WEDNESDAY THROUGH SUNDAY/. High pressure will build southward through the TAF period.

Mainly VFR conditions are expected but there will be some exceptions this morning as there are a few terminals with MVFR stratus. MVFR stratus will be possible this morning at other terminals as well but overall cloud coverage is expected to remain scattered. MVFR stratus will be possible again tonight.

Exact timing of the start and end time of MVFR stratus is uncertain and could vary a few hours from forecast.

Winds will be going from NE-E to more SE during today, with more variable directions tonight. Wind speed will mainly be near 5-10 kts.

OUTLOOK FOR 06Z THURSDAY THROUGH SUNDAY. Late tonight. Mainly VFR. Low chance of MVFR cigs. Thursday. VFR. Thursday night-Friday night. Chance of SHRA/TSRA with MVFR or lower conditions. Saturday and Sunday. VFR.

MARINE. Tranquil conditions are forecast on the waters as high pressure will be in control today through Thursday. A frontal system moves through Thursday night through Friday night, but the pressure gradient should be relaxed enough to preclude advisory level winds. Weak high pressure will then be in place for the upcoming weekend, maintaining sub-advisory conditions.

HYDROLOGY. No significant hydrologic impacts forecast during the period.

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

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
