Synopsis for the tidal potomac and md portion of the chesapeake bay..
high pressure will build over the region through Friday, then move offshore this weekend. A strong frontal system will likely impact the region on Sunday. Small craft advisories may be needed starting Saturday night, and are likely Sunday and Sunday night. Gales are possible Sunday into Sunday night, as well.

SYNOPSIS
A weak low pressure system and warm front will push across the region today. High pressure will bring milder weather for the start of the weekend. A potent storm system and cold front will sweep through Sunday and Sunday night. Cooler high pressure will return early next week.
NEAR TERM /THROUGH TONIGHT/
An upper ridge axis will build across the central CONUS today and slide east with surface high pressure centered across the Southeast. Net height rises will result through the day today, though one more trailing and potent shortwave dives through our area in the northwest flow aloft.
The aforementioned shortwave will pass through southeast Pennsylvania and New Jersey this morning. A band of snow is pushing across central Pennsylvania coincident with mid-level frontogenesis, warm advection aloft, and convergence along a low level jet. Upstream observations and webcams show that this band is overperforming a bit and is an hour or two early compared to latest hi res guidance; visibility is dropping to as low as 1 mile within the band with some moderate snowfall rates observed which is leaving a coating on roads. Aside from this concentrated band, still not much QPF expected as the NBM mean is only up to a few hundredths of an inch, so no significant snowfall amounts are expected. That said, hi res soundings depict a cloudy DGZ when forcing is maximized, especially across southeast PA, so a quick burst of snow is definitely possible. The latest NBM probabilities indicate a 60-70% chance of measurable snowfall (greater than or equal to 0.1") from the southern Poconos down through the Lehigh Valley, with values decreasing to 30-40% further south including the Philly metro, southwest New Jersey, and northern Delaware. While we are not anticipating any significant impacts, the snow will begin falling as early as the morning rush hour for portions of southeast Pennsylvania. This may result in some slippery spots on area roadways, sidewalks, or other elevated surfaces as roadway temperatures are at or below freezing this morning.
Any accumulation will be minimal with a few tenths of an inch, locally up to half an inch especially across southeast Pennsylvania. The precipitation will be predominately snow, however farther southeast, especially southeast of I-95, some rain could mix in as well as wet-bulb temperatures rise above freezing throughout the day. The band of precipitation should begin to weaken in intensity and coverage into the afternoon while drifting slightly northeastward.
Aside from the snow potential, it will be mostly cloudy and another chilly day with highs several degrees below normal, topping out in the low to mid 40s, except for the 30s in the southern Poconos and northern New Jersey. Wind will be from the west to southwest near 10 mph.
Will likely see another evening of persistent stratocu trapped beneath a subsidence inversion across eastern Pennsylvania as low level flow is forecast to remain out of the northwest which will pull lake moisture and reinforce cloud coverage. Elsewhere skies are expected to clear and with wind going light, we should radiate down into the mid 20s/low 30s in the urban areas.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
High pressure slides off the coast with west to southwest flow developing Friday and Saturday, with heights building through Saturday before they start falling ahead of a very potent trough. Through the short term, this means dry weather except possibly right near the end of Saturday night, when some showers ahead of the next system may start overspreading the region.
More sunshine will be had on Friday with the ridge building in and high pressure still fairly close by, with temperatures jumping about 10 degrees above readings expected today. However, by Saturday, the heights falling and developing onshore flow combined with the existing relatively cool stable air over the land appears to result in a wedge of cooler air, which will send the advecting warm air initially over the top on Saturday. Thus, expect Saturday to have temps not a whole lot higher if not nearly the same as Friday. This warm advection over the cooler surface should help result in a noticeably cloudier day as well, especially when combined with higher clouds advecting in from the west. As this warm front starts to buckle northwards late Saturday night, some showers or drizzle may develop, but otherwise, mostly dry conditions expected. Lows at night will also jump considerably thanks to the increased cloud cover and developing south to southeast flow, with lows Friday night closer to freezing while lows Saturday night closer to 40.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Potent storm system with strong surface cold front and upper level trough and deepening surface low will cross the region Sunday into Monday. Majority of the weather is likely Sunday night, when the low and front most likely crosses the area.
Strong southerly flow ahead of the system with retreating warm front may still bring some showers or drizzle early Sunday, with winds picking up as the front lifts northward. Gusts of 25-35 mph look likely on land with higher over the water. Temps will rise into the low 60s for much of the area. Then the strong front will bring a band of heavier rain and possibly some embedded thunder, perhaps even a line of low-topped squalls, across the region Sunday night. This could result in widespread wind gusts of 40-50 mph, perhaps locally higher, along with isolated issues with flooding. Temps will crash with the cold front as well, dropping fairly quickly into the 40s, with 30s and some mixed rain/snow in the Poconos. Certainly looks like quite a wild ride Sunday night.
Monday, winds will gradually die down as the system pulls further east, though the upper trough may keep some showers (mixed with snow in the Poconos) lingering. High pressure then builds back in for several days of cool but dry weather Tuesday through Thursday next week.
AVIATION /12Z THURSDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...
Today...VFR conditions are most likely to prevail outside of KRDG/KABE and a band of snow is expected to impact terminals as early as 13z through as late as 19z. MVFR CIGs and VIS increasingly likely for KRDG/KABE with snow, so have included prevailing MVFR conditions there this morning. Periods of IFR visibility are also possible at KRDG based on upstream observations this morning with a heavier band of snow so have included a TEMPO group there. MVFR conditions are less likely (40-50%) at the I-95 terminals but based on overperforming upstream obs, TEMPO group for MVFR conditions was included at all of these terminals. West to southwest winds increasing to near 10 kt. Low confidence in sub-VFR conditions, high confidence otherwise.
Tonight...VFR. Wind becoming light and variable. High confidence.
Outlook...
Friday...VFR. Winds southerly around 5 kts. High confidence.
Saturday...VFR most likely, but will need to watch for potential for low cloud development especially Saturday night. Wind southerly 5-10 kts. Moderate confidence.
Sunday...Sub-VFR periods with intervals of IFR likely as strong cold front crosses the region, most likely Sunday evening. Winds may gust 25-35 kts out of the south during the day then switch westerly at 30-40 kts at night. Line of low-topped convection also possible. Low confidence.
Monday...Conditions gradually improve with VFR most likely by day's end. Winds west to northwest 15-25 kts with gusts to 35 kts. Low confidence.
MARINE
The Small Craft Advisory will expire at 7AM and no further headlines are in effect. Westerly wind 15-20 knots and seas 3-4 feet will diminish to 10-15 knots with seas 2-4 feet.
Outlook...
Friday and Saturday...no marine headlines expected with south to southeast winds 10-15 kts and waves 2-4 ft.
Sunday...Gales likely by afternoon with brief gusts up to storm force not impossible especially after evening cold frontal passage or during potential squalls along the front. Seas building to 5-10 ft by Sunday night.
Monday...Westerly winds likely gradually drop below gales as the day progresses while seas slowly drop as well, but remaining in Small Craft Advisory levels by day's end.
PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...Small Craft Advisory until 7 AM EST this morning for ANZ453>455.
