SYNOPSIS
A warm front remains nearby through this afternoon. A weak trough moves through tonight, with high pressure briefly building in Monday. A back door cold front moves through Monday night followed by another frontal system for late Tuesday. The frontal system exits the area on Wednesday as high pressure builds in for Thursday and Friday. Another frontal system then approaches for Saturday.
NEAR TERM /THROUGH MONDAY/
Skies continue to clear out across the western half of the region, though much of southern CT and eastern LI remain in the gloom this afternoon. Where clouds have eroded, temperatures have been able to jump into the upper 60s and lower 70s, with still several hours of heating to climb higher. Conditions remain dry for now, but increase once again as a weak shortwave rides over the ridge late this afternoon and this evening. Increased PoPs to low likelies or high chance (50 to 60%) after 21Z for showers, with the possibility of a couple thunderstorms as well, especially into the Lower Hudson Valley. A few gusty downpours can't be ruled out with this activity either. The region should be almost entirely dry by 6Z tonight as the convection dissipates and moves offshore. Forecast remains on track and previous discussion follows.
A warm front remains nearby through the day. SW flow should give temperatures a boost compared to recent days. There will also be some clearing late morning into the afternoon. Even with mostly cloudy skies, the air mass is much warmer with 850 mb temps 11 to 13C (compared to 3 to 6C Saturday afternoon). The spread of high temperatures has been reduced, but the NBM deterministic and MOS output still lie at or below the 25th percentile, especially for NE NJ and the NYC metro. These outputs have typically been running too cool in similar setups, so will continue to side with the NBM 50th percentile, which yields highs in the upper 70s to around 80 for NE NJ, portions of the NYC metro and Lower Hudson Valley. Highs could end up a few degrees higher, especially in the normally warmer locations.
Onshore component of the wind across Long Island and Connecticut will prevent temperatures from rising as much, but should still reach the 60s to around 70 away from the immediate shore.
Another shortwave passes to the north late in the afternoon and evening. Some vorticity energy dives southeastward around the periphery of the high amplitude ridging aloft, helping to push a weak surface trough across the area. Several CAMs are signaling isolated-scattered convection, first across the Lower Hudson Valley just before sunset, and then potentially the rest of the area around our just after 00z. Model soundings are showing an average of 250-500 J/kg of MUCAPE. The NAM hints at some capping aloft, so will only mention slight chance of thunder for now. Brief downpours are possible, but no severe weather is expected out of this activity. Any convection the first half of the night quickly diminishes with dry conditions prevailing after midnight. It will be much milder with lows in the 50s to potentially low 60s in NE NJ and NYC metro.
SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/
The high amplitude middle and upper level ridging will continue over the eastern seaboard on Monday. The passage of the weak surface trough will leave behind a NW-N flow and a bit deeper mixing on Monday. Weak high pressure will remain over the region. There is still uncertainty with how high max temperatures will reach mainly due to timing of a back door front and any lingering cloud cover. The deeper mixing and NW flow should allow for temperatures to reach summerlike levels based on conditions being favorable for quick warming during the first half of the day. Models also tend to run too cool in early season warmth, similar to this setup. The NBM deterministic and MOS guidance continues to run close to the 25th percentile.
Given the aforementioned setup, have gone close to the NBM 50th percentile resulting in highs in the upper 70s and low 80s across CT, Lower Hudson Valley, and Long Island. Highs in NE NJ and the NYC metro are generally in the middle 80s. The potential continues to be there for temperatures to reach the upper 80s and possibly make a run at 90 in NE NJ potentially at Central Park. See climate section for records for April 29th.
The back door cold front moves through Monday evening into Monday night from northeast to southwest. Easterly flow develops which could set the stage for a few showers, but for now will leave the forecast mainly dry. Think low cloud development is more probable especially as the front works its way east of the area.
The ridge axis will begin to shift to the east on Tuesday as a shortwave axis approaches from the west. A wave of low pressure will develop along the front to our west Tuesday and then slowly slide east across the region Tuesday night. Chances for showers begin to increase Tuesday afternoon and especially Tuesday night. There may even be a few thunderstorms with instability aloft. Not anticipating strong convection at this time with the stable surface and easterly flow. Highs on Tuesday will be cooler ranging from the upper 50s and low 60s east to the upper 60s and lower 70s west.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
*Key Points*
*Near to slightly below normal temperatures to start the period followed by a slight warmup for the week's end into next weekend.
*Mainly dry conditions expected with a few chances of showers and thunderstorms as multiple frontal systems impact the area during the period.
Decent model agreement on a shortwave heading east of the forecast area on Wednesday AM as the trough axis shifts offshore. Upper ridging then builds back into the north east becoming a bit more amplified by the weekend. At the surface, weak sfc low and attendant fronts continue to head offshore on Wednesday. Shower chances remain for at least the first half of the day until the aforementioned trough axis clears the area.
Clouds will be slow to clear, but should become partly cloudy everywhere by late afternoon.
Surface high pressure then returns for Thursday and Friday, and it should remain mostly dry during this period under the large scale subsidence. Another upper low then ejects out of the Northern Plains and heads into Canada late Friday into Saturday.
An accompanying frontal system with this low then impacts the area late Friday into Saturday with additional chances of showers and possibly some thunder.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
A weak trough approaches this evening and crosses through overnight. A back door cold front moves through Monday afternoon.
VFR, except MVFR cigs over KGON thru 20z. Potential for a period of showers this evening increasing, with a low chance of thunder for KSWF, KHPN, KEWR, KTEB with marginal instability, during evening push, timing could be as early as 21-22z for KSWF. Slight chance of thunder for remainder of NYC/NJ metro terminals this eve, but confidence is too low to explicitly put in TAFs at this point. Drying conditions after 06z, with patchy fog possible for outying terminals.
S/SW winds 7-10kt for coastal terminals this afternoon with sea breeze. Winds veering SW and weaken this evening, becoming light W/NW late tonight with trough passage.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Timing of showers this evening may be an hour or so off. Chance of thunder, focused around 23-02z this evening, particularly KTEB/KHPN. S seabreeze of 10 to 15 kt likely for KJFK btwn 19z and 23z. Low prob for patchy fog for Mon AM push. Otherwise VFR w/ W/NW 5 to 8 kt.
OUTLOOK FOR 12Z MONDAY THROUGH FRIDAY...
Monday: Patchy early AM MVFR, then VFR. NW/N winds under 10 kt AM, shifting to E/SE winds in the aft/eve. Slight chance of PM shra/tsra.
Tuesday: MVFR or lower conds. PM SHRA potential, w/ slight TSRA potential for NW terminals. E/NE winds.
Wednesday: MVFR or lower conds. E/NE winds.
Thursday thru Friday: VFR.
