SYNOPSIS. A weak warm front lifts north overnight. A surface trough will then pass near or just north of the area Wednesday afternoon, followed by weak high pressure through Thursday. Low pressure will then approach from the south Friday into Saturday, followed by a series of weak fronts moving through from later Saturday into early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. An area of showers advancing NE ahead of a warm front over central NJ will pass through New London County in CT during the next hour, possibly producing a quick tenth of an inch. Showers right along the warm front were also dissipating across the Trenton area. A pop up shower can't be ruled out overnight with the passage of the warm front.

With plenty of cloud cover and patchy fog, overnight lows will only fall to around 70 degrees.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. A weak warm front lifts north of the area by Wednesday morning, followed by a shortwave trough approaching from the west in the afternoon. With better upper level support, shower and thunderstorm chances will increase Wednesday morning into Wednesday afternoon, especially for areas from New York City north and west. Convection is then expected to diminish after sunset as the shortwave pushes east, allowing ridging to build in aloft for Wednesday night.

With the exception of the immediate south-facing coastlines, temperatures on Wednesday are expected to rise into the mid to upper 80s area wide. Combined with dewpoints around 70, this should produce heat index values in the upper 80s to lower 90s across much of the area, with a few locations across portions of northeast New Jersey possibly seeing heat index values touch the mid 90s. Overnight lows will provide little relief, only falling into the upper 60s to lower 70s.

A moderate rip current risk is expected again on Wednesday due to relatively long period SE-S swell of 3 ft and S flow 10-15 kt.

LONG TERM /THURSDAY THROUGH TUESDAY/. High pressure builds briefly on Thursday. Temperatures on Thursday are forecast to rise to the upper 80s and lower 90s. Heat index values should reach the mid and upper 90s across the interior and the lower 90s elsewhere. There is the potential for some isolated to widely sct showers/tstms off higher terrain and perhaps sea breeze boundaries anticipated in an unstable, but capped and weakly sheared environment Thursday afternoon and evening.

There is a moderate risk for rip current development at Atlantic Ocean beaches on Thursday as long period southerly swell continues.

Low pressure moves up the Mid Atlantic coast on Friday, passing over the region Friday night into Saturday morning. Showers and thunderstorms are possible, especially Friday afternoon and evening likely just north east of the sfc low as it taps into a warm conveyor belt of Gulf and subtropical Atlantic moisture. Still low confidence on location of this heavy rain potential, as well as potential for breezy conditions on the east side of the low, as a potential 30-40 kt LLJ develops.

An upper-level trough and its associated cold front will move into the area Saturday, resulting in hot and humid conditions and the increase chance for showers and thunderstorms on Saturday and Sunday. The cold front will move off to the east Monday, but the upper-level trough will remain overhead bringing a potential for diurnal convection as well as a gradual trend to a more seasonable airmass through early next week.

AVIATION /01Z WEDNESDAY THROUGH SUNDAY/. A weak warm front just to the south this evening across central NJ will work slowly north and pass through the terminals overnight.

Ahead of the warm front, much of the area has either IFR or MVFR conditions with not much improvement expected until the warm frontal passage. Models soundings do show the low-levels gradually drying out as the flow veers to the south. Confidence on the time of improvement is low to medium as clearing could very well be delayed until around daybreak with the onset of daytime heating. That being the case, long episodes of stratus become less frequent as we get deeper into the warm season. At the very least, do expect VFR conditions to develop across all terminals before morning ends.

A pop-up shower cannot be ruled out during the night as well, but chances are too low to mention in any one TAF. Chances for showers and thunderstorms increase Wednesday afternoon, especially north and west of NYC with the approach of a trough. E-SE winds of 5-10kt will veer around to the S by daybreak with the warm frontal passage. Winds increase to around 10 kt Wednesday with a few gusts into the teens possible in the afternoon.

OUTLOOK FOR 00Z THURSDAY THROUGH SATURDAY. Wednesday Night-Thursday. Chance of MVFR afternoon or evening showers and thunderstorms, mainly from the NYC metros north/west. Friday-Saturday. MVFR or lower conditions likely in showers along with a few thunderstorms. Chance E-SE gusts 20-25kt for Friday into Friday night. Sunday. MVFR or lower possible at times with a chance of showers and thunderstorms.

MARINE. Sub-SCA conditions are expected on all waters through Wednesday night with winds generally remaining below 20 kt and ocean seas 3-4 feet.

SCA seas are likely Friday and into early next week with a persistent S/SW flow and strengthening wind fields owing to a possible coastal low nearing the region.

HYDROLOGY. A localized urban and poor drainage flood threat exists with any isolated thunderstorm activity through Thursday.

There is increasing potential for more widespread heavy rain Friday into Saturday as low pressure moves up the coast. More details as the week progresses.

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

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
