SYNOPSIS
A frontal boundary remains in the vicinity tonight, pushing east on Thursday, followed by high pressure Friday into Friday night.
The high moves off the coast Saturday as a cold front approaches. This front moves through Sunday night into Monday morning, then stalls south of the region. The front moves back north as a warm front Tuesday into Wednesday.



NEAR TERM /UNTIL 6 AM THURSDAY MORNING/
Frontal boundary remains in the vicinity tonight, though dry conditions should prevail. There may be some weak lift towards morning to account for some drizzle, but right now, think that this will more likely take the form of fog and low clouds. Went with patchy fog, but it could be more widespread for eastern areas as we head toward daybreak.

With clouds in the area tonight and a light southeasterly flow, low temperatures will be just a degree or two above normal for this time of year, in the upper 40s to lower 50s

SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/
Low pressure passes well north of the area Thursday, helping to push the frontal boundary through the forecast area during the day. The low, and associated developing shortwave dive southeast, passing east of the area overnight tonight.
Thereafter, high pressure builds in from southeastern Canada at the surface while a high amplitude ridge over the eastern Great Lakes moves slowly east, but its ridge axis remains just west or begins to enter the forecast area by the daybreak Saturday. Have gone with a dry forecast based on weak dynamics and track of the low and upper shortwave.

The main forecast challenge will be the high temperatures for Thursday. The area may be warm sectored for a brief time during the day Thursday, and the southwesterly to westerly flow that develops may help to bring in warm temperatures for this time of year. Given previous discussion on how cool NBM has been lately, and looking at NBM probabilities of greater than 75 and then 80 degrees, thinking is that much of New York City and points north and west will see highs in the low 80s, while southern portions of the city much of Long Island, and southeastern Connecticut remain in the upper 60s to lower 70s.
However, there is a great amount of spread in the NBM, with 15 to as much as 18 degree difference noted between the 25th and 75th percentiles. Therefore, there is a rather large amount of uncertainty with the temperature forecast.

Seasonably warm conditions expected Thursday night with lows generally in the 50s region-wide. Temperatures drop back to near normal on Friday.



LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/
An upper level ridge over the area Friday night into Saturday, as the flow becomes near zonal into early next week. A longwave upper trough across eastern Canada amplifies into the northeast Tuesday and moves off shore Wednesday as another upper ridge builds to the west of the area and moves into the region Wednesday. At the surface high pressure along the northeast and mid Atlantic shifts slowly east into Saturday as a cold front approaches. This front tracks across Sunday night into Monday, and becomes nearly stationary as the flow becomes parallel to the boundary. A period of some heavier showers will be possible Sunday as precipitable water values increase to 1.3 inches. Then Tuesday into Wednesday high pressure builds south from the Hudson Bay region of Canada into the eastern Great Lakes. With a deep low tracking northward from the northern plains into southern Canada Tuesday into Wednesday the stalled cold front will move slowly northward as a warm front. There is uncertainty as to the movement of the front as high pressure, and an upper ridge will be in place. Temperatures Friday night through Sunday will be around 5 degrees above normal, and then Sunday night into Wednesday 5 to 10 degrees above normal. For highs and lows Monday through Wednesday used a blend of NBM and NBM 75th percentile to raise temperatures a few degrees above the NBM.
Depending on the movement of the warm front next week, there is a chance that a few locations will have a record high low Monday night into Tuesday morning.

AVIATION /20Z WEDNESDAY THROUGH MONDAY/
Weak high pressure remains just east of the area through this evening, then gives way to a weak frontal system approaching from the west. There is some uncertainty as to how quickly the associated warm front/cold front get through the area on Thursday, which could lead to wind timing and intensity issues.
The front may struggle to get east of the coastal terminals.

Mainly VFR for the remainder of this afternoon. Widespread IFR/LIFR conditions are the forecast to develop this evening into the early morning hours Thursday. Improvement to VFR is forecast to occur quickly after 12Z Thursday.

SE winds generally 10kt or less through the overnight, then gradually veering from west to east on Thursday as a frontal system attempts to work across the area. The westerly wind shift may remain west of the KLGA and KJFK for much of the day, before going around in the early evening. There is fair amount of uncertainty as to how far east the west winds get on Thursday. W/NW winds 10-15kt G20kt are possible for those locations that do come around.

...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

There is only low to medium confidence on the timing of IFR ceilings tonight.

The timing of the wind shift to the W/NW on Thursday could be delayed significantly, especially at KLGA and KJFK. Warm front could get hung up across the area during the daytime hours.

OUTLOOK FOR 18Z THURSDAY THROUGH MONDAY...

Thursday Afternoon: VFR everywhere. Some W/NW gusts around 15-20KT in the afternoon.

Friday: VFR.

Saturday: Mainly VFR. Chance of showers and MVFR cond in the afternoon, becoming likely overnight.

Sunday...Chance of MVFR or lower in showers. ESE winds G15-20kt.

Monday...VFR.
