SYNOPSIS
The last of the cold weather remains through tonight. High pressure remains in control through Thursday as temps begin to moderate ahead of a low pressure system and cold front that passes through Friday and Friday night. The weekend will start out dry on Saturday but will become increasingly more unsettled for Sunday and into the middle of next week.
NEAR TERM /THROUGH TODAY/
A swath of mid-level clouds coinciding with a passing shortwave and warm advection aloft is beginning to lift out to the northeast across New York and New England, with scattering and clearing skies expected through the rest of the overnight. Bit of a tricky low temperature forecast tonight as the clouds have initially offset radiational cooling, but as skies clear, and with dew points in the low to mid teens, the floor is pretty low for temps tonight. Complicating factors are a low level jet that will move overhead and a weak gradient wind that may offset otherwise ideal radiational cooling as low as some MOS guidance suggests. Hi res forecast soundings depict a very steep surface inversion overnight tonight, so in the end still thinking we do cool fairly well with lows dropping to the 20s save for the urban areas and coastlines with low 30s.
Surface high pressure centered to our south will hold a dominant influence over the region through the near term. Even with this surface high pressure shifting offshore to our south Thursday, conditions will remain tranquil and quiet through the length of the term.
Some shortwave energy to our west will propagate through the region this evening into tonight, but with high pressure holding influence over the region, the only impact from this should be a brief period of increased cloud cover. Skies will become clear after midnight as most of the shortwave energy moves further eastward.
Warm air advection will continue over the region through the length of the near term; High temperatures Thursday will be much warmer than those seen today. Delmarva and NJ coastal areas could see the low 50s, while the rest of the region (with the exception of Sussex County NJ and the Poconos) sees the mid to upper 40s.
SHORT TERM /TONIGHT THROUGH SATURDAY/
The forecast for this period remains on track with some rain moving through the region on Friday.
An area of low pressure will develop near OK/TX Thursday night and will move northeast. An expansive cloud shield in association with this system will begin to move in late Thursday night into early Friday. This will result in noticeably warmer temps Thursday night compared to the night prior, with lows generally in the 30s.
Light rain begins to overspread the region on Friday from west to east beginning late in the morning to early afternoon timeframe. Some brief periods of moderate rain are possible Friday afternoon into the evening before the system moves out by early Saturday. Surface through 850mb temps do look to be quite warm, thanks to the warm air advection pattern ahead of the system with the high moving offshore, so we are only expecting rain for this event.
Rain should end by Saturday morning but the next in the series of upper level waves will be quickly on its heels as it moves into the lower Great Lakes Saturday. At the least, this should keep conditions mostly cloudy for Saturday but it still looks at this point like enough deeper moisture will have moved out with the first wave to keep it mainly dry. It will be fairly mild with highs mostly in the 50s, except around 60 over southern DE.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
Not much change to the long term forecast, but one thing we have gained confidence in is that the long term will be unsettled. The exact details are increasingly more uncertain as there will be several shortwaves tracking around the base of the longwave trough by the end of the weekend into the middle of next week. This will keep the area under persistent cloud cover with several opportunities for precipitation throughout the period, although any given day does not look to be like a total wash.
The first of the several shortwaves passes by Saturday night, but another shortwave is soon on its heels that passes on Sunday. Most of the area should remain precip free initially Saturday night, but rain showers will overspread the area into Sunday.
The forecast from this point forward then becomes extremely uncertain as the timing and progression of the longwave trough aloft differs variably. Have kept at least a chance (30-50%) of rain showers Sunday-Tuesday due to the abundance of shortwaves tracking across the area through this time. Eventually, a cold front will pass through near the middle of next week where the region will (finally) dry out. Temps through the period will be slightly above normal toward the start of the period, then gradually trend to slightly below normal toward the end of the period. For now, this appears to be mostly rain, with only a slight chance of some snow showers mixing in the higher elevations around mid week.
AVIATION /06Z THURSDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...
Tonight...VFR. Calm or variable winds less than 5 kt may tend SW in exposed spots. SCT/BKN mid level clouds giving way to SKC overnight. High confidence.
Thursday...VFR. Light WSW wind will back more out of the SSW in the afternoon, up to 10 kt. Clear skies may give way to some high clouds in the afternoon. High confidence.
Outlook...
Thursday night...VFR. S-SW winds around 5 kt. High confidence.
Friday through Friday night...Sub-VFR likely with periods of rain especially during the afternoon and evening. Southerly winds around 10 kt during the day, becoming NW-N winds around 5-10 kt at night. Moderate confidence.
Saturday through Saturday night...Mostly cloudy with potential for sub VFR conditions during the day Saturday due to low stratus with a higher potential for this at night. Winds generally northeast 5 to 10 knots. Low confidence.
Sunday through Sunday night...Sub-VFR probable with rain showers. NE winds around 5-10 kt with gusts up to 15 kt during the day, becoming NW winds around 5-10 kt at night. Low confidence.
Monday...Sub-VFR probable with rain showers. W-NW winds around 10 kt. Low confidence.
MARINE
Tonight...WSW winds 14-18 knots with seas 2-4 feet. As a low level jet moves overhead overnight, some occasional gusts up to 25 kt may occur, mainly beyond several miles from shore, and not enough to justify any advisories.
Thursday...SW winds in the 10-15 kt range with seas of 2-3 feet.
Outlook...
Thursday night through Friday...Potential for southwest winds gusting up to 25 knots Thursday evening into the overnight.
Winds should then ease somewhat for Friday. Seas of 2-4 feet through this period.
Saturday through Saturday night...No marine headlines expected. N-NE winds around 10-15 kt. Seas of 3-4 feet.
Sunday through Sunday night...No marine headlines expected. NE winds around 10-15 kt during the day, becoming NW winds around 10-15 kt with gusts up to 20 kt possible. Seas of 2-3 feet.
Monday...No marine headlines expected. W-NW winds around 10-15 kt with gusts up to 20 kt possible. Seas of 3-4 feet.
