Cold front will continue to move offshore later this evening, with high pressure building back in behind it. Another cold front will cross through the area late Tuesday. On Tuesday. High pressure then rebuilds offshore Christmas day and will remain in place through late week.
Through tonight As of 205 PM Sun,
Key Messages,
- Colder tonight with lows in the upper 20s inland
Broad low-amplitude trough continues to sit over much of the eastern CONUS this afternoon with a weak embedded shortwave lifting off the Delmarva Peninsula. Quick moving Canadian low pressure and attendant cold front are pushing off the Atlantic coast now with strong high pressure building in behind it.
Stronger surge of CAA expected tonight as high pressure continues to build in from the northwest. Once the high clouds associated with the front move out this evening skies should be mainly clear, but steady north winds should keep the boundary layer mixed enough to prevent any fog or stratus formation. Lows tonight drop into the upper 20s inland and around 40 along the coast, but well sheltered areas could fall into the mid 20s.
Monday As of 210 PM Sun,
Key Messages,
- Below normal conditions continue tomorrow with high pressure over the region
Mostly sunny but below normal conditions continue Monday as high pressure slides to the coast and eastern NC finds itself under classic northeast flow regime. Temps will remain mostly in the upper 40s to low 50s south and west of US 70 with winds weakening through the day.
Monday night through Sunday As of 2 AM Sun,
Key Messages,
- Mostly dry conditions expected this week into this weekend with only some minor chances for rain Tuesday and Friday
- Above normal conditions expected through this weekend, with highs in the 60s Christmas Eve and Christmas Day
High pressure pushes offshore Monday night with heights building the rest of the week as an upper level ridge moves over the region from the Deep South. We'll still be on the periphery of the ridge Tuesday which will allow a quick moving cold front to dip into the Carolinas briefly, bringing a 25-50% chance of light rain (though amounts are expected to be very light). Behind this front a stronger surface high will develop across the Gulf Coast Christmas Eve through Friday, which will push highs up well into the 60s, and possibly into the 70s on Friday. Late Friday or early Saturday a cold front will move into the region, and could bring some light rain, though again, precip amounts look to be minimal.
00z Monday through Friday As of 5:50 PM Sunday, VFR conditions are expected through the period. Broken high clouds will dissipate later tonight with mostly clear skies persisting until tomorrow evening when a few high clouds will move back in. Light winds are currently out of the NW and will veer to the E through the period as a dry front crosses the area.
Outlook: Another mainly dry front with just some trivial sprinkles or light showers on Tuesday, though VFR will persist. Quiet conditions cont through the upcoming week.
As of 220 PM Sun,
Key Messages,
- SCA expected tonight into Monday evening behind cold front
- Another period of Small Craft conditions appears likely Tuesday ahead of a weak frontal boundary
Cold front pushed across area waters earlier this morning, with winds now northwesterly at around 10 kt. Surge associated with increasing CAA will nudge winds higher early this evening to N 15-25 kts with gusts to 30 kts, with an isolated gust to 35 kt with the initial surge, through tomorrow morning. Winds then decrease quickly through Monday, becoming NE 10-15 tomorrow afternoon.
Seas are already up to 3-5 feet with a relatively long period of 11-12 sec. Seas will increase up to 7-9 ft late tonight through early Monday morning, and then subside to 4-6 ft by early afternoon.
Current SCA headlines are in excellent shape and no changes were offered this forecast package.
Outlook: Marine conditions briefly improve Monday night before SW winds increase Tuesday morning ahead of a cold front. Winds will become SW 15-25 kts with gusts to 30 kts by early Tuesday afternoon through at least the first half of Tuesday night, focused primarily over the warmer waters of the Gulf, with seas building to 4-7 ft. Improving conditions expected Christmas Eve, with decent boating conditions persisting through Christmas Day.
