SYNOPSIS. Strong high pressure will shift to the northeast through the overnight as low pressure pushes across the Southeast and towards the Carolina coast. The low will strengthen as it tracks up the East Coast later Friday and Saturday, then it continues to move away during Sunday. After a brief period of drier air, another low pressure system moves across the Tennessee Valley and into the Mid- Atlantic Monday into Tuesday. High pressure then looks to settle into the region Wednesday into Thursday.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. For the 830 PM and 930 PM updates, due to only thin cirrus and low dew points (light to no wind) the hourly temperatures and low temperatures were lowered some for several areas given trends. The clouds will increase and thicken overnight and this is expected to halt the temperature drop and result in either a steady state or slow rise toward morning. The 00z Wallops Island, VA raob shows a very shallow layer that is moistening just below 850 mb. There are some clouds in the 4000-5000 foot range nearby, however it is rather dry below and above this layer. As a result, it will take much of the night to moisten the lower levels. Despite this, a stratocumulus deck is expected late tonight across much of the area which may then lower some closer to daybreak. Still see at least some drizzle potential especially if more of a stratus deck occurs, however there remains uncertainty given the dryness of the airmass currently in place. This will be monitored overnight especially given the cold temperatures.
Otherwise, strong high pressure will shift to the northeast tonight, allowing moisture and warmer air to begin filtering back into the area. The low-level flow (e.g. 925-850 mb) will veer southeasterly overnight which will allow some lower clouds to begin moving into the area after midnight or so. Consequently expect overnight lows (generally ranging from the mid 20s to around 30) to largely occur before midnight with most locations being several degrees warmer by daybreak.
This increasing low-level moisture will combine with some weak isentropic ascent to potentially support some very light precipitation (drizzle) early Friday morning. Given how dry we are initially (e.g. current dewpoints are mostly in the teens) combined with the fact that the upper-level dynamics won't arrive until later in the day, generally doubt we will see much measurable precip. There is also a small chance that the overunning setup could result in some freezing drizzle in spots along the northern periphery of the moisture return, but confidence in this occurring is too low to warrant any headlines at this time.
SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/. A lead shortwave will begin to approach during the day on Friday and an UL jet streak will approach from the south. These factors will combine with continued isentropic ascent to increase precipitation chances through the day on Friday. Although expect that the bulk of the precipitation will be light in this period (the heavier precipitation will likely occur in the extended) do have high enough confidence to include likely PoPs for just about everywhere by Friday afternoon. Regarding Ptypes there is the potential for some light FZRA (particularly north of I-78) Friday morning, but given uncertainty over both PoPs and the thermal profiles in this period did not include any ice accumulations at this time. Also can't rule out some patchy fog/mist Friday afternoon as low-lvl moisture and precipitation begin to increase (particularly over SE PA).
Temperatures will be warmer than today, although uncertainty (as is typical in these prefrontal overunning setups) does increase further away from the coast. Generally expect highs along and east of I-95 to reach the upper 40s to lower 50s, while low-mid 40s will be the norm over interior eastern PA and NW NJ.
LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/. A novel, Part 1 (shorter long term) .
A wet and wild beginning to the extended forecast period as low pressure moves out of the Southeast toward the Carolina Coast by Saturday morning. Strong PVA and WAA associated with a strongly negatively oriented mid- level trough will lead to strong pressure and height falls over our region and into the Northeast, progressing the surface low quickly off to the north and east through the day Saturday and into Saturday night. A strong jet developing over New England will also aid in the rapid intensification of the low, especially as it moves from the mid-Atlantic and into the Northeast. The low looks to track mostly over our region, thus we will bear much of the impact. Rain looks to fall heaviest early Saturday morning, where much of the area will likely pick up at least half an inch of rain in the first portion of the day. Given the track of the low, have a feeling that rain rates will lessen mid to late morning and into the afternoon behind the first initial surge in rain early Saturday morning as the center of the surface low moves near or just west of the Delaware Valley. This may work to dry slot us a little more than what some of the models are suggesting, so only made some minor adjustments to the QPF grids for now.
Give the antecedent conditions, minor flooding could be an issue. Normally, rainfall below two inches over this span of time wouldn't lead to significant concerns, but the appreciable rainfall we experience earlier this week has almost saturated portions of the soil, limiting the amounts necessary to cause concerns. PWATS ranging from one to one and a half inches support moderate to heavy rainfall, thus there is increased concern for localized flooding. Rainfall above two inches will likely cause concerns so if we can keep amounts below this, things should stay fine. Rainfall totals right now range from one to one and a half inches, so no flood products appear to be needed at this time but this could change if forecast totals trend upwards.
Considerable warm air advection with southeasterly flow ahead of the system will lead to mild conditions Saturday with 850 mb temps from 10 to 15 degrees C. Thus, highs are forecast to make it into the low to mid 50s again Saturday. There isn't a substantial push of cold air with this system, unlike the snow producer earlier this week, thus, no frozen precip is forecast as the low moves northeast Sunday. Temperature will drop but not too drastically for this time of year with afternoon highs Sunday sitting in the mid to upper 40s. It will be breezy, however, with wind gusts up to 25 mph into the afternoon. Low temperatures Sunday night will drop into the upper 20s to lower 30s across the region.
A novel, Part 2 (longer long term) .
A ridge of high pressure will be across the region early Monday. After a seasonably chilly morning, the high will move offshore and clouds will increase over the area. Precipitation will follow for the afternoon when temperatures should have warmed enough to allow mostly rain for the area. We have to still mention the possibility for some snow at the onset for the W and NW areas, but there is plenty of uncertainty at this range about the beginnings of the storm. Earlier precip favors more mixed/snow while later timing will bring mostly rain. Either way, a period of 24 to 30 hours of (mostly) rains across the CWA with perhaps 3/4 to 1 1/2 inches of QPF possible. Temperatures will be a little above normal Tue as long as the present storm track just N of the area holds. Highs will be in the 40s N and 50s S. The EC is showing much warmer readings attm, but not ready to go with this solution attm.
Precipitation ends overnight Tue into Wed morning, perhaps as a little snow, as colder air arrives. The few days after that will feature mainly dry but cold weather. High pressure will settle across the area at the end of the week. Highs will mostly be in the 30s, but some low 40s for Delmarva are possible.
AVIATION /03Z FRIDAY THROUGH TUESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Overnight . VFR with high clouds giving way to a lowering ceiling from southeast to northwest after midnight. Timing regarding when the ceilings lower to MVFR is less certain, but it is generally expected to be in the 06-12Z time frame (starting at ACY and MIV). South to southeast winds around 5 knots becoming light and variable, then becoming light east or east-northeast late. High confidence in lowering ceilings; low confidence with the timing of MVFR ceilings.
Friday . Generally MVFR to start the day, with conditions deteriorating to IFR in the afternoon with some visibility restrictions in mist also possible. Some light rain should occur at times at all terminals, especially in the afternoon. Easterly winds 5-10 knots. High confidence in general flight category trends and winds; low confidence in specific category timings.
Outlook . Friday night and Saturday . MVFR to IFR as moderate to heavy rain moves through the region. Easterly winds turning southwesterly from 5 to 10 knots in the morning with gusts up to 15 knots strengthening to 10 to 15 knots and gusts to 20 knots in the afternoon. Moderate confidence.
Sunday . MVFR conditions possible, especially in the early morning as rain showers lift north and east. VFR conditions return as the low pressure as the storm system lifts to our north. Breezy with westerly winds from 10 to 15 knots and gusts from 25 to 30 knots possible. Moderate confidence confidence.
Sunday night . VFR conditions expected with northwesterly winds from 5 to 10 knots. High clouds will be on the increase by Monday morning as another storm system begins to close in on the region. Moderate confidence.
Monday and Monday night . Mainly VFR conditions expected. Rain/snow may move into the terminals by late morning/early afternoon. West to northwest winds from 5 to 10 knots. Low confidence.
MARINE. As high pressure moves northeast of the area a general easterly- southeasterly flow will develop over the waters tonight through the day on Friday. Expect conditions to remain below criteria through the day on Friday with easterly winds sustained 10-15 kts and gusting to 20 kts. 2-3 ft seas tonight will increase to around 4 ft by Friday afternoon.
Outlook . Saturday . Winds may approach Small Craft Advisory Criteria by the late afternoon with gusts nearing 25 knots out of the southwest. Seas from 5 to 7 feet.
Saturday night . Small Craft Advisory winds out of the southwest will prevail. There is the potential for a Gale force gusts early Sunday morning. Seas drop to 3 to 5 feet.
Sunday . Gale force gusts possible out of the west from 30 to 35 knots through the afternoon. Seas ranging from 4 to 6 feet.
Sunday night . Small Craft Advisory winds out of the west-northwest with gusts near or exceeding 25 knots. Seas from 2 to 4 feet.
Monday and Monday night . Seas are expected to fall below 5 feet by early Monday morning and will drop to around 1 to 3 feet through the day. Some 25 knot gusts may occur early Monday before 12Z but are expected to be out of the northwest around 10 to 15 knots throughout the remainder of the day.
