.SYNOPSIS... A coastal storm will continue to affect the region through today, bringing significant impacts to the coastal areas. Improving conditions expected by Tuesday as the storm weakens and moves out to sea. High pressure will begin building back into the region during the latter half of the week.

&&

.NEAR TERM /THROUGH TONIGHT/... As of 8:00 AM...have allowed both the remaining High Wind Warnings and Wind Advisories for Monmouth and Ocean Counties to expire. Winds have peaked overnight and are gradually subsiding this morning. Occasional gusts in excess of 40 mph are still possible, however the threat has diminished.

Previous discussion is below: The more expansive rain shield has continued to move westward across our area. There continues to be low-level moistening for areas west of I-95 with showers and drizzle for these areas. A robust easterly low-level jet at 850 mb has continued to lift northward across our far eastern areas and especially the marine zones. The KDIX radar velocity data shows an area of 55-60 knots of wind around 3500 feet AGL just offshore of Monmouth county. This will enhance some lift through this morning, and as a result areas of rain are anticipated to continue to expand farther west through this morning. The main impacts will continue to be felt across our coastal communities due to onshore winds and significant/severe coastal flooding. Wind gusts along the coast have been as high as 50-60 mph with a few over 60 mph so far.

For the rainfall associated with this system, we have already seen amounts of 0.50-1.50 inches with localized higher amounts along the coast. Outside of the coastal areas, totals drop off quickly, especially closer to I-95 and west of I-95. Additional rainfall looks to be around 0.25-0.50 outside of the coastal areas with this falling mainly through today. Our coastal areas from Atlantic County northward to Monmouth County could pick up an additional 1-2 inches, especially with the enhancement from the robust low-level jet located in this area currently. By tonight, we trend drier with some showers lingering.

The main concern with this system continues to be the coastal flooding (see coastal flooding section below). The winds will continue to be on the stronger side through daybreak which is why some of the headlines were briefly extended. During the day today, it will still be breezy with gusts inland near 30 MPH at times and near 40 MPH at the immediate coast.

Our temperatures today will be in the upper 50s to upper 60s. There won`t be much of a drop overnight with temperatures mainly in the 50s.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... Coastal low will slowly move east into the ocean and weaken Tuesday, with chance of rain gradually ending and potentially some breaks of sun returning, but gusty winds will linger much of the day, especially near the coast. Highs rebound well into the 60s for most.

Clouds gradually continue diminishing on Tuesday night as the low continues heading out to sea. Wind should stay elevated so not much risk of fog. Lows mostly in the low to mid 50s.

Wednesday looks relatively sunny even as a cold front pushes southward across the region, resulting in an increase in the northwesterly winds. Highs should also be elevated, well into the 60s with some spots cracking 70.

Cold advection takes strong hold behind the front Wednesday night under mostly clear skies. Lows mostly in the upper 30s to mid 40s.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/... Canadian high pressure dominates Thursday and Friday, with sunny to partly cloudy skies. This may be the coldest air mass of the season thus far, with many locales struggling to reach 60 during Thursday, and only a little milder on Friday. With much of our northern zones now out of the growing season due to last week`s freeze, the question of frost/freeze headlines is murky, as areas which haven`t frozen yet may still have enough of a breeze Thursday night to keep them from freezing, despite the chilly air mass in place. Lows Thursday night will be in the 30s for much of the region, except 40s in the warmest spots, while staying a few degrees warmer Friday night.

Warm front slips across the region as high pressure presses east of the region Saturday, with temps warming back closer to 70 during the day despite a bit of an increase in mainly high cloud cover. Next frontal system then approaches Saturday night and Sunday, with more clouds and an increasing risk of showers. Enough warm advection should occur to hold many areas at 50 or higher Saturday night, and push temps into the low-mid 70s for most on Sunday.

.AVIATION /18Z MONDAY THROUGH SATURDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Rest of Today...A mix of MVFR and IFR conditions around the region. Likely IFR conditions are to prevail for KMIV/KACY, with MVFR prevailing at all other terminals. Have included TEMPO groups for I-95 terminals for IFR ceilings over the next several hours. Periods of light rain, intermittent showers, mist and drizzle expected. North-northeast winds around 10-15 kt with gusts up to 25-30 kt possible. Moderate-low confidence overall.

Tonight...Anticipate IFR conditions (primarily ceilings) to prevail for much of the overnight period at all terminals. Visibility restrictions possible as light rain transitions to showers, mist and drizzle, especially after midnight. Northeast winds around 10-15 kt with isolated gusts up to 20 kt possible, especially near KACY. Low confidence overall.

Tuesday...IFR ceilings early, improving to MVFR ceilings by mid-late morning. Gradual improvement to VFR possible after 18Z from west to east. North-northeast winds around 10-15 kt with occasional gusts up to 20 kt. Moderate-high confidence.

Outlook...

Tuesday night through Friday...VFR rest of this week.

&&

.MARINE... As of 8:00 AM, have downgraded the remaining Storm Warnings to Gale Warnings on the Atlantic coastal waters as wind observations offshore are gradually diminishing. Otherwise, other Gale Warnings remain unchanged at this time.

North-northeast winds to continue with winds sustained between 15-30 kt with gusts up to 40-45 kt possible this afternoon. Winds will gradually subside a bit, but still remain upwards of 35-40 kt overnight. Seas of 12-16 feet today and 10 to 12 feet overnight.

Outlook...

Gale conditions will continue on the ocean waters Tuesday as the low pulls out to sea and away from the region, with SCA on Delaware Bay. Should drop back mostly to Small Craft Advisory conditions by Tuesday night for the ocean waters and potentially sub-SCA on the bay, but then probably level off at this condition (at least SCA on the ocean waters) through Thursday. Should mostly drop below SCA conditions on the ocean waters Friday wind-wise, but seas may yet remain elevated to SCA levels.

&&

.TIDES/COASTAL FLOODING... Updated the tide forecasts based on current tidal departures. No changes made to the coastal flood warnings and advisories. With the latest update, the only site still forecast to get to major flooding is Barnegat Inlet and southern portions of Barnegat Bay. Otherwise, moderate flooding is expected for the remainder of the New Jersey and Delaware coasts, Delaware Bay, and southern shores of the Raritan Bay. Minor tidal flooding is expected on the tidal Delaware River with this evening`s high tide, where a Coastal Flood Advisory remains in effect.

Additional beach erosion and dune breaching are possible along the entire New Jersey Shore and for Delaware Beaches due to the very high/dangerous surf conditions through today.

It looks as if the high tide later today will be the last tide of significant concern. There may minor tidal flooding with the high tide tonight and especially tomorrow. However, we will have a better idea the degree and extent of minor tidal flooding with those cycles once we see the tidal departure trends with today`s high tide.

That being said, given the nature of this event, tidal flooding impacts could linger longer on back bays such as Barnegat Bay in NJ and the Indian River Bay, Rehoboth Bay, and Little Assawoman Bay in DE.

No tidal flooding is expected for our eastern shore counties along Chesapeake Bay.
