Synopsis for the long island and connecticut coastal waters - High pressure continues sliding to the southeast through this afternoon. A warm front approaches tonight and moves north on Sunday. Weak high pressure returns late Sunday into Monday. A back door cold front moves through Monday night. A frontal system approaches from the west and moves through the area on Tuesday. High pressure then briefly follows for midweek.

SYNOPSIS
High pressure will remain in control of the prevailing conditions through early next week with low chances of showers and storms.
Below normal temperatures to start eventually rise above normal over the weekend. A weak system will be a more widespread chance of storms on Tuesday, although temperatures will remain above normal through much of next week.

NEAR TERM /THROUGH TODAY/
Latest satellite imagery shows some high clouds have filtered into the region a bit earlier than initially expected. As a result, our lows tonight are likely in jeopardy of not being realized by a few degrees in many spots. Only the NJ pine barrens have cooled substantially before high clouds have moved in. Some breaks in the clouds are moving eastward towards the region and could help cool a few spots. While generally expecting most locations outside the pine barrens to end up a few degrees warmer than the previous forecast, will maintain the Frost Advisory as is for now since some patchy frost remains possible in the most sheltered areas.

Saturday will start mainly clear with skies then clouding over through the late morning into the afternoon from west to east as the warm front approaches. There will be some showers associated with this front approaching from the west but I think they should be fizzling out as they reach eastern PA since the low levels will be fairly dry. As a result, we just mention isolated to scattered light showers in the forecast for Saturday afternoon over eastern PA and Delmarva extending into adjacent portions of NJ roughly as far east as around Trenton. The cloud cover will keep temperatures a bit cool with highs in the upper 50s to low 60s.

SHORT TERM /TONIGHT THROUGH MONDAY/
The main story for Sunday into Monday will be the strengthening ridge across the East Coast. 500 mb heights look to increase to near 580 dam by Monday, values more typical of summertime. At the surface, high pressure will be centered offshore of the Carolinas, helping to advect warmer and more moist air into the region. The result will be much above normal temperatures. Saturday night will see lows nearer to normal though (mainly in the 40s), as this will be the transition time between airmasses. Cloud cover will also limit radiational cooling Saturday night, and winds will be from the south near 5-10 mph. The warm advection aloft should result in some isolated to scattered showers overnight, mainly near and north of Philly.

By Sunday, temperatures will rise well into the 70s to near 80 degrees in many interior locations. The limiting factor for temperatures Sunday will be how quickly the morning cloud cover clears out. The cloud cover looks to hang on the longest across the northern portions of the area, so areas north and east of a line from roughly Philly to Reading will likely stay in the mid 70s at best. Some isolated showers are possible in the Poconos, Lehigh Valley, and NW NJ, but the strong ridging aloft will likely hinder development. Lows Sunday night will be about 10-15 degrees above normal, mainly in the mid 50s to near 60 degrees with clearing skies.

Monday will be the warmest day of the stretch with high temperatures soaring into the mid 80s in most interior locations under partly cloudy skies. Highs in the more urbanized areas could top out in the upper 80s, though reading of 90 degrees or higher are unlikely. The northwest flow will add a downsloping component to the winds and thus also help to boost temperatures locally near the urban corridor. The offshore wind will also allow for a notable warmup even along the immediate coast, with highs getting to the low to mid 70s before the sea breeze kicks in. As the gradient flow weakens and shifts eventually to the southwest then south, the sea breeze will likely make significant inland progress into the I-95 corridor and perhaps even farther inland from there during the evening. This will cool temperatures off into the 70s and 60s by late evening.
Dewpoints will be near 60 degrees, so the Heat Index won't be much different than the air temperature on Monday. No heat headlines are anticipated.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
The very warm weather that was in the short term part of the forecast spills over into the long term as the upper ridge that promotes it only gradually moves away later Monday and Tuesday.
Highs Tuesday will be a few degrees cooler than Monday (the warmest day of the whole forecast period) but still be in the upper 70s/low 80s most places. Temperatures will drop a few degrees Wed thru Friday but remain in the 70s for highs most places. Cooler temps for the southern Poconos and near the shore.

There are no widespread precipitation events foreseen during the long term. There is an opportunity for showers Tue/Tue night as shortwave energy rides up the backside of the retreating ridge. More showers are possible Thursday as an upper low and surface fronts arrive from the west. Pops during the Tue/Thu periods are in the slight chance or low chance range.
