An area of low pressure will move northeast from the great lakes into quebec through Thursday. A warm front will cross the region today and tonight, followed by a cold front Thursday. High pressure will then build into the region Friday and Saturday. A developing area of low pressure to our northwest will drag a cold front through the region Sunday, with a coastal low potentially developing along this front early next week. Near term through tonight The big concern in the forecast today lies with the freezing rain drizzle potential across the northern portion of the cwa. The nam has a stronger signal for this to occur, whereas the GFS is a bit warmer drier. Not overly confident of what will end up transpiring. The large-scale lift associated with a subtle midlevel perturbation moving through the region during the day is weak, at best, and there are some questions as to how quickly the low levels will moisten sufficiently for any precipitation to occur. Bufkit soundings are quite variable model to model, and the overall appearance of the more aggressive models is for (near-)saturation generally at below the 700-mb level. This suggests any precipitation will be light and liquid. Would not be surprised if little more than drizzle occurs northwest of the fall line through the day given the shallow look of the moist profiles and the rather dry near-surface layer. Of course, the other question will be surface temperatures, with statistical guidance appearing much too warm much too quickly. The typically colder NAM (raw) model output was favored here, which slows the warming temperatures north of i-78 considerably during the day. So far, this has worked well for temperatures early this morning in these areas (especially the poconos and far northern new jersey). With the above in mind, have slight chance for (light) freezing rain starting late this morning. It doesn't appear that this will make it further south than the lehigh valley at this point, as surface temps will likely be above freezing by the onset of precipitation southeast of the fall line. The window for near-freezing temperatures in the lehigh valley is quite short, with temperatures well above freezing likely by mid afternoon. The best potential for a longer duration of near-freezing temperatures remains in carbon and monroe counties, where a winter weather advisory is already in effect. Confidence is too low for expansion elsewhere given questions regarding precipitation coverage, onset versus marginal (and warming) surface temperatures, and overall model variability. Tonight the main forecast question is how quickly the steadier rain moves into the area, with overall consensus suggesting a slower onset. Generally, increased pops from northwest to southeast through the period, with timing matching a consensus hi-res blend. The main period of precipitation looks to start after midnight, possibly reaching the atlantic coast as late as daybreak. Kept temps on the colder side for today's highs, given the cold air over the past couple days, and the overall tendency for it to stick around in these scenarios longer than simulated. Also, bumped temps up a touch across DELMARVA to account for the stronger warm air advection trend through the day. As it stands, highs should range from the mid 30s across the poconos to the low 50s across southern delaware. Winds will pick up through the day, with gusts above 25 knots possible along the coast and over DELMARVA by evening. Given the southerly flow and warm air advection, lows Wednesday night will likely not deviate much from Wednesday's highs, with a warming trend possible through the period. Another sensible weather impact of note tonight will be the increasing south to southeast winds generally southeast of the urban corridor. Winds may gust 30 to 35 mph in this area (possibly stronger near the coast) as a strong low-level jet develops aloft. Though mixing will not be efficient, it may be strong enough to generate some rather breezy conditions overnight. Short term Thursday through Thursday night Strong surface low in quebec 12z Thursday will lift northeast through the day, dragging a cold front through the region. Very strong southerly southwesterly low-level flow in advance of the front will continue to advect warm and unusually moist air into the area. Forecast pws approach 1.5 inches during the morning, which is in record territory climatologically. Additionally, very strong and deep ascent aided by favorable positioning of the right entrance region of an intense 250-mb jet streak, considerable differential cyclonic vorticity advection, and low-level isentropic ascent aided by a 70-kt synoptically-forced low=level jet will generate widespread precipitation across the mid-atlantic during the morning. Bufkit soundings show very weak instability in advance of the front, so little or no lightning is expected (except maybe off the coast). Nevertheless, strong frontal lift appears to generate sufficient lift for locally intense enhanced precipitation. With the high- octane air in place, a period of heavy rain is probable in advance of the front. Model QPF is generally 1 to 1.5 inches from 09z to 21z across the area, with most of this precipitation likely occurring in a 3-6 hour period at any particular location. With cold soils, months of antecedent wet conditions, and relatively high rain rates expected at times during the day, flooding potential seems elevated. Have issued a flood watch for the lehigh valley southeastward to the i-95 295 corridors for Thursday. Though the watch is technically an areal flood watch, flash flood potential exists here, given the possibility of high rain rates producing quick rises in sensitive streams and urban areas. For more information, see the hydrology section below. Winds will also be elevated in advance of the front, aided by the aforementioned low-level jet and sufficient mixing. Additionally, any convectively-induced precipitation may mix down some very strong winds aloft. Will need to watch this potential closely as the event unfolds. The front races offshore during the afternoon, with precipitation potential rapidly lowering behind it. Cold air will filter in quickly. Depending on how quickly the precipitation ceases upstream of the front, may see a quick brief switchover to snow showers before the precipitation ends, especially in the northwest cwa. Temperatures will surge in advance of the front, with readings in the 50s to near 60 southeast of the fall line. However, temperatures will fall rapidly behind the front, with lows below freezing virtually everywhere Thursday night. Skies should rapidly clear by Thursday night, although some lingering moisture may keep the low clouds present in the far northwestern cwa. Cannot rule out a few flurries here as low-level northwest flow develops and a weak perturbation approaches the northern mid-atlantic overnight. Long term Friday through Tuesday Following the system, mainly dry but colder conditions move back in for Friday lasting through Saturday as the next high moves in. Temperatures will be slightly below average, but still an improvement to what we have seen the past couple days. Lots of uncertainty in this period. In the big picture, a long wave trough will remain present over eastern north america with a closed low at 500 mb persisting around hudson bay. The pattern looks to remain active with several potent pieces of energy moving southward eastward around this trough towards the coast, potentially phasing with southern stream energy. An area of low pressure looks to develop across the great lakes as several of these pockets of energy associated with shortwave troughs phase by Sunday. This keeps precipitation in the forecast through the weekend and into the middle part of next week. This will start as snow showers across the poconos and likely build southeast across the CWA Sunday. The chance for snow and rain showers could last really through the middle part of next week. Still considerable uncertainty in how much moisture will be available and how things will come together. Kept a slight chance of rain showers (south) and snow showers (north) in the forecast through Wednesday. Temperatures remain cold with highs |
slightly below average through the beginning of the week. Wednesday looks to be quite chilly with highs remaining below freezing across much of the forecast area. && Aviation 09z Wednesday through Sunday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Rest of tonight...VFR with light south winds. High confidence. Wednesday... GenerallyVFR, though CIGS will be lowering and may reach sub-vfr thresholds northwest of philly by mid to late afternoon. Cannot rule out some drizzle or showers at rdg abe as well. Winds generally south around 10 kts. Llws increases from the southwest rapidly this afternoon. Moderate confidence. Wednesday night... Conditions will be deteriorating gradually to sub- vfr and may reach ifr or worse near after midnight. Rain chances increase from northwest to southeast, especially after midnight. Winds south around 10 to 15 kts, possibly gusty near southeast of phl. Southwesterly llws anticipated through the night. Moderate confidence. Thursday... Cig vsby restrictions will continue through at least early afternoon, with rain (heavy at times). Southwesterly llws will also continue through the morning. Conditions are expected to improve rapidly during the afternoon, withVFR possible late. Southwest winds 10 to 20 kts with higher gusts before frontal passage, becoming northwest afterward. Moderate confidence. Thursday night... MainlyVFR with west to northwest winds around or below 10 kts. Moderate confidence. Outlook... Friday and Saturday... MainlyVFR conditions expected. Winds generally below 20 knots. High confidence. Saturday night through Sunday night... Cold front may bring rain and or snow showers, thus possibly lowering visibilities and bringing restrictions, especially at krdg and kabe. Moderate confidence. Marine Sub-advisory conditions exist on the waters at this time, but south to southwest winds are already increasing off the new jersey coast. Winds are expected to reach advisory levels later this morning, so have moved up the start time of the small craft advisory to 6 am on the atlantic waters. Conditions should remain sub-advisory on delaware bay through the day. Conditions will deteriorate further tonight, as south to southwest winds strengthen to 20 to 25 kts with gusts to at least 30 kts. Gales cannot be ruled out, especially on the atlantic waters, though low-level temperature profiles are not climatologically favorable for their development. As such, did not issue a gale watch at this time. Conditions will worsen on delaware bay, and the small craft advisory remains in effect overnight. Seas on the atlantic will increase to 5 to 10 feet tonight. Outlook... Thursday: small craft advisory in effect, and gales are possible. Seas 5 to 10+ feet. A cold front moves through during the afternoon, with winds switching from south or southwest to northwest. Rain likely, with visibility restrictions probable. Cannot rule out thunder, but confidence was not high enough to include in the forecast. Thursday night: rain moves out, and northwest winds diminish but will likely remain above advisory criteria much of the night. Seas will also remain elevated but will lower as the night progresses. Small craft advisory was extended through 4 am Friday for delaware bay and through 6 am for the atlantic waters. Friday and Saturday... Sub-sca conditions expected with westerly winds 10-15 knots. Seas from 4-6 feet. Saturday night through Sunday night... Sub-sca conditions expected with easterly winds initially, turning southwesterly from 10-15 knots. Seas from 3-5 feet. Hydrology We have issued a flood watch for late tonight through Thursday afternoon from the lehigh valley and northwest new jersey southeastward to the i-95 295 corridors. A cold front will move through the area on Thursday, with a round of rain, moderate to heavy at times, expected to move through the region in advance of the front late tonight into tomorrow morning. Expected storm totals are generally from 1 to 1.5 inches, with locally higher amounts possible. Normally, these totals would not be forecast to produce much flooding. However, a number of factors suggest an elevated threat exists... 1) antecedent wet conditions, including from the rainfall this past weekend. 2) relatively cold soils, aided by the arctic air that spread across the region the past couple of days. 3) the expectation of most of this rain occurring in a three-to-six hour period. With higher rain rates expected during a portion of the event, especially just in advance of the frontal passage on Thursday, additional runoff will be generated, which could lead to flooding of particularly sensitive spots (e.G., urban areas and quickly-responding creeks and streams). 4) light to moderate rain occurring for a few hours before the heaviest rainfall occurs, which may act to saturate soils sufficiently for efficient runoff during the most intense rainfall. An isolated instance of flash flooding is possible, especially if the heaviest rainfall (and high rainfall rates) occurs along the urban corridor or atop smaller stream creek basins that respond rapidly to runoff. River flooding cannot be ruled out, especially on the passaic and millstone rivers, if the axis of heaviest rainfall intersects the associated basins. Phi watches warnings advisories Pa...
