SYNOPSIS. A surface high will move slowly across the Great Lakes and Northeast states this weekend before settling across the Appalachians for much of the upcoming week. A cold front is forecast to move into the Northeast Thursday night and Friday.

NEAR TERM /THROUGH TONIGHT/. Few changes needed to previous fcst or grids. Dew points were adjusted down in a few spots.

Sprawling high pressure centered in the Great Lakes region this morning will shift slowly eastward through tonight, likely positioned in southern Quebec by 12z Sunday. Northerly surface flow in advance of the high will gradually become more northeasterly and weaken as the surface pressure gradient relaxes with the high's approach to the region. Winds have increased through the morning, with speeds 10 to 15 mph and gusts 20 to 25 mph occurring. The winds speeds are expected to lower gradually during the afternoon, and may become light and variable by tonight.

This leads to the main forecast concern: frost potential in the Poconos and northwest New Jersey tonight. Models were too aggressive with cooling temperatures this morning, as strong mixing in the cold advection regime in advance of the surface high mitigated more substantial radiational cooling. However, expectations are that decoupling will occur quickly after sunset tonight. As a result, the forecast is for temperatures to drop below consensus guidance. Will likely need a frost advisory for Carbon, Monroe, and Sussex Counties tonight, but have held off at this time in coordination with neighboring WFOs owing to ongoing headlines this morning to the northwest.

Forecast highs today are in the mid 50s to lower 60s in the Poconos and northwest New Jersey and in the middle 60s elsewhere, based on a blend of continuity and statistical guidance. Forecast lows tonight are in the middle to upper 30s north of Interstate 78 and in the 40s elsewhere, based on a blend of colder hi-res model guidance and continuity.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. A vort max will dig southeastward across the Mid-Atlantic on Sunday, which will reinforce the high pressure already established in the Northeast and adjacent southeast Canada. This may lead to another breezy day, with northeast winds increasing to 10 to 15 mph with a few gusts 20 mph or so. A mostly sunny and cool day is expected across the area.

Lows on Sunday night will be fairly similar to those the previous night, with another round of frost likely in the northern CWA (especially north of I-80). Frost headlines will likely be required.

High pressure will begin to shift southwestward on Monday as TC Teddy continues to churn northward well east in the western Atlantic. By Monday night, high pressure will become positioned in the central/southern Appalachians. Continued dry conditions are expected across the area Monday and Monday night, with temperatures remaining quite similar to the previous two days.

LONG TERM /TUESDAY THROUGH FRIDAY/. The era of high pressure continues across the eastern U.S. during the medium-range period.

As TC Teddy begins its race northward into and east of the Canadian Maritimes, high pressure will remain entrenched in the Appalachians for much of the week. Broad midlevel ridging will exist across the U.S., with faster flow remaining near the International Border. A fairly potent vort max will move from the northern Plains on Wednesday to the Northeast on Friday, but high pressure in the east-central U.S. will likely prevent any substantive moisture from advecting poleward in advance of the trough. As such, the attendant cold front is expected to move through the region with little or no precipitation (and will be weakening anyway as it approaches the surface high). Notably, the 00z GFS trended much wetter both with the front on Friday and with a reinforcing vort max the following weekend, so it is possible PoPs will need to be raised in subsequent forecasts should operational models trend in this direction. However, other operational models lend little support to this scenario at this juncture.

Temperatures will be warming in advance of the vort max Tuesday through Thursday, likely becoming a few degrees above seasonal averages Wednesday and Thursday. Modest cooling is expected after frontal passage on Friday. Dry weather is forecast Tuesday through Thursday, with only a slight chance of showers in the far northern CWA on Friday as the shortwave trough moves through the area.

AVIATION /16Z SATURDAY THROUGH WEDNESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . VFR with north to northeast winds around 10 kt with gusts to 20 kt. High confidence.

Saturday night . VFR with winds either becoming light and variable or generally northerly under 10 kt. High confidence.

Outlook .

Sunday through Wednesday: VFR with northeast winds on Sunday and Monday and west to northwest winds on Tuesday and Wednesday. Winds generally 5 to 15 kt (lighter at night), though a few gusts to 20 kt or so may occur during the late morning and afternoon hours each day.

MARINE. Winds and seas are now solidly above advisory criteria on the Atlantic waters and also Delaware Bay (elevated platforms). Gusty north to northeast winds will continue into the early afternoon, but are expected to diminish as the afternoon wears on. However, seas will remain well above advisory thresholds (5 to 8 feet) through tonight. Additionally, winds should strengthen again overnight, likely at least flirting with advisory criteria after midnight.

A small craft advisory remains in effect through the period for all waters. We may lower it across Delaware Bay later this afternoon, it it seems like the winds will not increase too much overnight.

Outlook .

Sunday . Small craft advisory continues for all waters, though conditions may be fairly marginal on Delaware Bay. Northeast winds 15 to 25 kt with gusts to 30 kt on the ocean. Speeds will be lower on Delaware Bay, but gusts to 25 kt may occur. Seas on the Atlantic waters of 6 to 10 feet are forecast. A high surf advisory may be required for the beaches.

Sunday night and Monday . Small craft advisory extended for the Atlantic waters, with seas 7 to 11 feet likely. Advisory conditions may occur on Delaware Bay on Sunday night as well, though confidence is low. Northeast winds 15 to 25 kt on the ocean, with somewhat lighter winds on Delaware Bay. A high surf advisory may be required for the beaches.

Monday night through Wednesday . Winds becoming northwest 10 to 20 kt. Seas of at least 5 feet are expected on the Atlantic waters through at least Tuesday night, so the small craft advisory will likely need to be extended.

Rip currents .

Rough surf is expected on the coasts of New Jersey and Delaware through early next week. Waves in the surf zone will likely reach 5 feet by late this afternoon and will continue building on Sunday. A very long-period east-northeast swell will gradually develop today and tonight, with the latest model guidance suggesting this may occur by as early as this afternoon. Latest observations suggest the period has increased to at or above 10 seconds already, which is generally higher than model guidance has suggested to this point. With seas already 5 to 8 feet, waves in the surf zone will likely reach 4 to 6 feet today, continuing to climb on Sunday.

As a result, we are forecasting a high risk of rip currents today and Sunday. The rip-current risk will remain elevated through at least Tuesday.

TIDES/COASTAL FLOODING. Astronomical tides remain elevated from the new moon this past Thursday. With strong north-northeast winds continuing this morning and seas building, another round of widespread minor tidal flooding is expected with this morning's high tide on the Atlantic coast and on the southern coast of Delaware Bay. Coastal flood advisories remain in effect.

The latest model guidance continues to suggest the high tide late this evening will feature less widespread coastal flooding, so we have held off extending the advisory through this high tide. However, localized minor flooding is possible, especially on the southern New Jersey and Delaware Atlantic coasts. Another round of more widespread minor flooding may occur during the Sunday morning high tide. Subsequent rounds of minor flooding are possible through Monday, as well. Later forecast shifts will reevaluate this potential and may issue additional advisories as needed.

For the northern coast of Delaware Bay and the tidal Delaware River, spotty minor flooding may occur through Monday's high tides, but more widespread flooding is not currently anticipated.

For the eastern shore of Chesapeake Bay, tidal flooding is not currently anticipated.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . High Rip Current Risk through this evening for NJZ014-024>026. Coastal Flood Advisory until 2 PM EDT this afternoon for NJZ012>014-020-022>027. DE .
