Key Messages:
As of 300 PM EDT Tuesday...
Key Messages:
- increasing chances of light rain along the coast tonight into Wednesday morning as low pressure slides northeast along the coast.
Current satellite imagery shows a well defined areas of clouds along and west of a stalled frontal boundary along the SE US coast. With high pressure, north of the area centered near Eastern Maine, stretching down the eastern seaboard a strong NE flow has developed. The combination of the stalled front and NE flow has led to an increase in clouds along the coast and these clouds have spread more inland as a weak shortwave trough rides along the front. So far the rain has remained offshore. Models continue to suggest that an area of low pressure will form along this stalled front off the Carolina coast this evening through the overnight hours. The NAM12 continues to appear to wrap the moisture well to far inland and without a stronger trough aloft, don`t think there is enough support for that type of system. Have leaned more toward the GFS and HRRR to keep the rain along the coast. So raised the chances for rain to about 60% along the coast and held onto a slight chance back to the I-95 corridor. Think the pcpn will be light overall, but could be persistent (light rain/drizzle) for the overnight hours. Overall expect rainfall amounts to be 0.50 or less for most areas. Some high res models try to show some much higher amounts, but without convection, have a hard time seeing those totals being realized. Temperatures should remain mild with overnight lows generally in the upper 50s west to upper 60s east with the clouds in place.
Conditions should begin to slowly improve through the day on Wednesday as the weak low along the front continues to move NE away from the coast. The NE flow continues for most of the day with a turn more northerly to northwesterly late in the day. This will keep the clouds around along the coast much of the day with a gradual clearing from west to east during the afternoon.

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... As of 300 PM EDT Tuesday...
Key Messages:
- Dry and trending warmer for Thursday through Friday.
High pressure is expected to dominate the weather from New England to the Gulf Coast through this time period. This will continue the dry weather and with the return of more sunshine, expect temperatures to climb back to more seasonable levels with readings in the upper 70s to low 80s Thursday to the low to mid 80s on Friday.

.LONG TERM /SATURDAY THROUGH TUESDAY/... As of 300 PM EDT Tuesday...
Key Messages:
- Dry, partly-mostly sunny, with seasonable temperatures this weekend.
The weekend should be rather pleasant with temperatures near normal. The sfc high pressure to the north strengthens, remaining in control through the weekend. This will result in dry weather and seasonable temperatures in the upper 70s to the mid 80s through Monday. Models beginning to advertise a backdoor cold front moving into the area early next week. Right now the timing looks like Monday afternoon or evening with cooler and drier conditions for Tuesday. But with limited moisture, not anticipating much chance for rain with the backdoor front.

.AVIATION /19Z TUESDAY THROUGH SUNDAY/... As of 300 PM EDT Tuesday...
High pressure is centered NE of the region with a trough offshore that continues to bring strong NE winds to coastal terminals with gusts to ~25 kt today at ORF/ECG, and 20-25 kt at SBY/PHF. Clouds continue to spread inland areas as far W as FVX with lower to MVFR levels along the coast. As a area of low pressure develops along the coastal front and slides northward tonight, expect the ceilings to drop to IFR levels with some light rain possible for ECG/ORF/PHF/SBY. Without a strong upper trough to pull the low pressure area farther west, think RIC will remain MVFR.
The area of low pressure will slowly pull NE away from the area on Wednesday with a gradual weakening of the NE flow. But it will take some time for the clouds to abate and ceiling to lift. Do think by the afternoon hours some improvement is likely, but will likely still be mvfr levels in the late afternoon along the coast.
Outlook: MVFR conditions are possible Wed afternoon into Wednesday night. Otherwise, improving conditions on Thursday with dry WX and VFR for all terminals through Saturday.

.MARINE... As of 230 AM EDT Tuesday...
Key Messages:
- Small Craft Advisories remain in effect for all of local waters.
- Seas build to 6-9 ft today with a High Risk of rip currents at all area beaches.
- Another round of SCAs is likely Friday into next weekend.
Latest sfc analysis depicts a ~1029 mb area of high pressure centered over New England with a coastal front off the Southeast coast and a weak surface low along it. This has resulted in a tight pressure gradient with NE winds 15-25 kt with gusts up to 30 kt across the local waters. High pressure gradually moves E through mid week with a weak surface low gradually moving NNE along the coastal front well offshore. As such, the pressure gradient will remain in place with NE winds averaging 15-25 kt with gusts up to 30 kt continuing through this evening, gradually becoming N and diminishing to 15-20 kt with gusts up to 25 kt tonight through Wed evening. As such, SCAs remain in effect for all local waters today with SCAs ending at 6 AM Wed for the upper rivers, 4 PM Wed for the upper Ches Bay, Lower James River, and Currituck Sound, 7 PM WEd for the middle Bay, 10 PM Wed for the Lower Bay, 4 AM Thu for the mouth of the Bay (due to elevated waves), and 6 AM Thu for the coastal waters. Will note that SCAs for the S coastal waters may need to be extended through Thu if seas remain elevated. Additionally, while frequent gusts up to 35 kt are not expected, a few gusts up to 35 kt are possible across the coastal waters this afternoon. However, wind probs for 34 kt gusts were only 35-40 percent for a few hours. As such, have opted to hold off on any Gale Warnings at this time with an SMW possible if a brief period of 34 kt gusts develops.
Seas early this morning were 4-6 ft across the N coastal waters and 6-9 ft across the S coastal waters. Seas build to 7-9 ft across all of the coastal waters by late this afternoon into this evening before gradually subsiding tonight into Thu. Will note that it is possible for peak wave heights to be higher (up to 9-10 ft) across the NC coastal waters today with nearshore waves up to around 8 ft. As such, will need to closely monitor trends today to see if a High Surf Advisory may be warranted. However, the current thinking is that the highest seas will remain offshore with generally sub 8 ft seas along the beaches. Seas of 4-5 ft may linger across NE NC through Thu, however, will keep the current end time of the SCAs for the coastal waters at 6 AM Thu for now across all of the coastal waters.
The next area of high pressure off to our W looks to build in Thu, enough to relax the pressure to some extent with mainly sub-SCA conditions expected (though winds stay elevated at 10-15 kt with gusts up to 20 kt). Onshore northeast winds increase again Fri into next weekend with an additional SCAs likely needed, especially for the lower Ches Bay and S coastal waters.
Rip Currents: A High Risk of rip currents is expected at all beaches through Wednesday, potentially easing some by Thursday.

.TIDES/COASTAL FLOODING... As of 440 AM EDT Tuesday...
A prolonged period of onshore flow and high seas offshore will lead to increasing water levels over the next several tide cycles. Widespread nuisance to minor flooding is expected across NE NC, locations along the lower Ches Bay, and areas along the tidal Rappahannock, York, and James Rivers with the next several high tide cycles beginning this morning and continuing through at least Wednesday afternoon`s high tide. As such, have expanded Coastal Flood Advisories across these areas and have extended them through Wednesday afternoon. The exception is the Atlantic coast of the OBX from srn VA Beach down to Duck where only this morning`s high tide is expected to reach minor flood stage. Farther north, departures will take longer to increase, but are forecast to slowly rise with the potential for seeing minor flooding by Wednesday afternoon. As such, have opted to hold off an Coastal Flood Advisories at this time for the upper Ches Bay as well as the MD beaches. Water levels remain elevated with prolonged onshore flow through the end of the week, though departures likely drop off a bit by Thursday. Will note that additional nuisance to minor coastal flooding is possible through Thursday for portions of the area, however, confidence is lower than for today into Wednesday.
