Synopsis for the tidal potomac and md portion of the chesapeake bay..
high pressure will continue to slide offshore tonight. Another frontal system and area of low pressure push through the area Friday into Saturday. A stronger frontal system looks to cross the waters Sunday into Monday. High pressure returns to the waters by the middle of next week. Small craft advisories may be needed Friday night due to southerly channeling.

SYNOPSIS
High pressure will remain in control through tonight. A low pressure system and cold front will pass through Friday and Friday night. The weekend will start out mostly dry on Saturday but will become increasingly more unsettled for Sunday and into the middle of next week.
NEAR TERM /THROUGH FRIDAY/
Nudged hourly temps up just a bit to match current obs and trends with this update; lingering cirrus coverage and a light breeze have resulted in a slow decrease after sunset. Winds should diminish over the course of the next couple hours as a sharp surface inversion develops and the clouds clear out as well, so expect temps will then drop off for the rest of the overnight hours, though with dew points some 10-15 degrees higher this time tonight than last night, we'll hold warmer tonight in the upper 20s/low 30s.
Surface high pressure centered to our south will continue to influence our region through tonight as it moves further eastward offshore. However, with time, surface low pressure currently centered over TX/OK will look to move northeastwards.
With this low pressure system forecast to swing northeastwards through MO/IL tomorrow, some precipitation chances will be brought to region tomorrow afternoon onwards.
Cloud cover will build in tomorrow morning rather quickly, PoPs looking to be in the forecast by tomorrow afternoon. The overall trend from guidance (i.e., decreasing PoPs overall with higher chance PoPs occurring later) is continuing. Given this, will include mainly chance PoPs for much of the region after 1PM. Mainly likely PoPs for much of the region is included 4PM onwards. Precipitation experienced by the region overall during the period will not be impactful at all. At best, 0.10-0.15 inches of rainfall can be expected.
SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/
Showers will continue Friday night into early Saturday as warm air advection and Gulf of Mexico moisture associated with a weakening shortwave moves through the area. Cloud cover is expected to dominate during this timeframe, as the moisture does not look to scour out between systems followed by a secondary low or cold front later Sunday. It will be mild with highs in the 50s to low/mid 60s, with the warmest day looking to be Saturday.
There is more uncertainty on Sunday as the guidance is somewhat split on whether we get just a cold front moving trough or low pressure crosses our area. The latter would result in a more widespread rain instead of some showers. Overall, it looks like at least weak low pressure slides near or over our area and this would keep our area more stable especially with a northeasterly low-level flow for a time. The onshore flow scenario would tend to result in cooler temperatures than currently forecast for Sunday, however given the uncertainty on the synoptic features that will be moving across or near our region we opted to just cool the temperatures slightly from Saturday. The guidance that has more of just a cold front moving through later Sunday, shows some mainly elevated instability Sunday afternoon although it is on the weak side.
LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
The long term period of the forecast looks to be unsettled though there remains quite a bit of uncertainty beyond early next week.
Showers will gradually decrease across the region Sunday night into Monday as a cold front crosses the region. A rumble of thunder or two cannot be completely ruled out, particularly closer to the coast. However, model guidance generally depicts only a few hundred joules per kilogram of CAPE and any instability that does exist will drop off as we head through the overnight hours. Chances for showers increase again for Monday with the passage of a mid-level shortwave with high pressure building to the south of the region for Tuesday.
Heading into the mid-week, the upper-level pattern remains progressive. Latest model guidance generally forms a consensus that another upper-level trough begins to develop and dig out of the midwest and move eastward towards the Eastern Seaboard. Associated with this deepening trough is a surface clipper system that quickly progresses out of the Great Lakes region and into the Mid-Atlantic during the middle of next week. This low then passes offshore and model guidance suggests that it will rapidly strengthen once it does so. However, uncertainty remains in how quickly the upper-level trough deepens and therefore, model guidance differs in exactly where and when the surface low may strengthen. As a result, PoPs for most of the long term beyond Tuesday remain around 20 percent or less.
Temperatures will begin above normal (highs in the 50s/low in the 40s/30s) to start the long term period then fall back to near normal to slightly below normal (highs in the 40s/low in the 20s) for the middle of next week.
AVIATION /03Z FRIDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Tonight...VFR. SSW winds around 5 kt. High cloud cover will move out before midnight for most sites. Expecting winds to go light and variable, if not calm, at KRDG/KABE after 02z tonight. Other sites will likely prevail at 5 knots or less out of the southwest. Guidance indicates LLWS particularly for the I-95 terminals and KRDG/KABE as a 25-35 kt low level jet moves overhead, so have included LLWS mention at those sites through 07z. High confidence.
Friday...VFR through late afternoon. High level cloud cover building in during the morning and ceilings lowering through the afternoon. -SHRA works in from the southwest for most sites by 22/23z with MVFR ceilings becoming increasingly likely (80% chance) by that time.
Outlook...
Friday through Saturday morning...Sub-VFR at times with showers.
Moderate confidence.
Saturday afternoon/night...VFR during the day then sub-VFR at night with showers. Low confidence.
Sunday...More low clouds/showers possible with MVFR/IFR. Low confidence.
Sunday night...Gradually improving to VFR as showers decrease but patchy fog is possible. Moderate confidence.
Monday...Periods of sub-VFR conditions possible with chances for showers, particularly in the afternoon. Westerly wind gusts 20-25 knots. Shower chances and wind gusts decrease overnight. Moderate confidence.
Tuesday...VFR. Westerly wind gusts up to 20 knots. Moderate confidence.
MARINE
A Small Craft Advisory is in effect until 3AM Friday for coastal waters from Sandy Hook to Manasquan Inlet as gusts up to 25 knots and seas 3-5 feet are expected through the middle half of the overnight hours tonight coincident with a low level jet moving overhead. Otherwise no marine headlines are in effect.
SSW/SW flow 15-20 kts will continue until around 11PM tonight.
Thereafter, SSW/SW winds 10-15 kts can be expected through Friday. Gusts near 20 kts are possible Friday.
2-3 foot seas this evening will build to around 3-4 feet tonight before returning to 2-3 feet for Friday.
Outlook...
Sub-SCA for Friday and into the weekend. Rains and fog possible Friday/Friday night and again Sunday/Sunday night into Monday.
Small Craft Advisory conditions possibly develop early Monday morning as westerly winds begin to increase. SCA conditions are likely by Monday evening with gusts up to 30 knots possible. Winds decrease back below SCA criteria during the day on Tuesday. Seas of 2 to 4 feet throughout.
PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...Small Craft Advisory until 3 AM EST Friday for ANZ450.
