Synopsis for the long island waters and new york harbor.. High pressure continues to move offshore today. Meanwhile, weakening low pressure and an associated warm front will gradually approach on Tuesday. The low will pass to the south Tuesday night, with the warm front remaining to the south on Wednesday. Low pressure will then move across Wednesday night, and become nearly stationary across eastern canada later this week as high pressure builds from central canada into the plains states. The high will then slowly build eastward toward the east coast this weekend.

Area Forecast Discussion National Weather Service Mount Holly NJ 1232 PM EST Mon Feb 24 2020

SYNOPSIS. A warm front located to our south today will begin lifting northward overnight tonight, before stalling to our south Tuesday. Several waves of low pressure will move along this boundary to our south Tuesday into Wednesday. A stronger area of low pressure will lift across the Great Lakes region Wednesday into Wednesday night, pulling a cold front across the east coast. Breezy northwest flow will be in place for Thursday, Friday, and Saturday, before shifting to the north Sunday, before high pressure builds across the region Monday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Will bump up max temps by several degrees, as it is quite warm out there even with increasing cloud cover.

Surface high pressure will remain centered across the western Atlantic Ocean through the day. This will allow weak southerly flow to continue bringing warmer air and increasing dewpoints into the forecast area. Meanwhile, the next system to impact our region will continue developing as it moves across the southern Plains toward the central Mississippi Valley by the end of the day. Upper diffluent flow associated with this system will move into our region throughout the day. This will lead to increasing and gradually lowering cloud cover, especially by late afternoon into the evening. The main forcing for precipitation will not arrive until later tonight though, so the forecast will remain dry through the evening.

Temperatures will be on the order of 15 degrees or so above normal with S-SW winds 5-10 mph.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/. The upper wave associated with the system to our west will continue moving toward the region overnight. The surface low will move slowly east across the Ohio Valley then weaken as the parent upper wave flattens. Despite the surface low's demise, the upper wave will still bring an area of rain showers toward our area overnight with PoPs increasing from SW to NE toward daybreak. With mainly overcast skies, temperatures will remain mild overnight with lows mainly in the 40s. Winds will be light and variable, but generally favoring a southeasterly direction.

LONG TERM /TUESDAY THROUGH SUNDAY/. Unsettled weather with multiple rounds of precipitation will begin the long term period Tuesday and Wednesday, followed by mostly dry weather but breezy conditions for the remainder of the week into the weekend.

For Tuesday, a warm front will be lifting toward the area, but will likely stall just to our south Tuesday night into Wednesday. Several waves of low pressure are forecast to move along this frontal boundary, and likely remain just to our south. Several short waves will pass over the area or just south of the area, during this period as well. There will be plenty of moisture north of the warm front, which will lead to several periods of light rain Tuesday through Wednesday. When it's not raining, with the amount of moisture trapped under an inversion, there could also be areas of fog and/or drizzle. This would most likely occur late Tuesday, Tuesday night, and early Wednesday.

By late Wednesday into Wednesday night, a strong area of low pressure will move through the Great Lakes region, which will pull a cold front across the east coast. There is some weak instability forecast, mainly by the NAM, around 200 J/kg. The instability is elevated, but it may be just enough for an isolated thunderstorms or two to occur. A triple point low will likely move right overtop of the area, which could limit thunderstorm potential for areas north of the low, but it could also enhance rainfall for many location. Regardless of any thunderstorms, PW values approach one inch, some moderate to briefly heavy rainfall will be possible. Rainfall amounts are expected to be between 0.50-0.75 inches or less, so no issues are expected. Once the front and triple point low moves through the area, it will bring most precipitation along with it. There may still be some wrap around showers behind the low, especially for portions of northeast Pennsylvania and northwest New Jersey where any precipitation could change over or mix with snow. Another concern behind the front and low will be an increase in winds. Winds will likely begin to gust 20-30 mph overnight.

The two low pressure systems, the Great Lakes low and the triple point low, will lift to our northeast through Thursday and begin to merge into one low Thursday night into Friday. As this happens, our area will remain under strong west to northwest flow. This strong flow will continue through the weekend, although winds will shift toward the north by Sunday. Winds will remain gusty with gusts reaching at least 20-30 mph.

With the northwest flow, a few weak surface troughs, along with short wave/vorticity impulses aloft could move across the area Thursday through the weekend. With each one of these short wave and trough passages, some lake effect snow showers could affect portions of northwest Pennsylvania and northwest New Jersey.

AVIATION /18Z MONDAY THROUGH SATURDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
