SYNOPSIS
High pressure will prevail across the region through the end of the week yielding above normal temperatures. A back door cold front will push into the region Friday night, then stall out by Saturday. A stronger cold front will pass through the region Sunday night through Monday, and that front may linger near the area through Tuesday.

NEAR TERM /THROUGH TODAY/
Forecast is on track early this morning. Only minor tweaks were made. Quiet night overall.

Dry conditions continue through tonight as ridging aloft remains in place across the Mid Atlantic region, while high pressure remains offshore of the east coast. Some high clouds continue to linger which could result in temperatures being a touch warmer, but may also preclude low clouds and fog development. Will see how things trend and see if any fog develops, but think it will be confined to the more rural and sheltered areas.

For today, the ridge aloft begins to get squeezed, but remains across the area, while high pressure offshore sinks a little to the south. Temperatures on Thursday are expected to be a degree or two warmer than Wednesday, with similar dewpoint and humidity levels. Therefore the heat index values will be similar to Wednesday, if not slightly higher. Therefore we will keep the Heat Advisory for Thursday. The forecast during the day Thursday will be dry as the backdoor frontal boundary is expected to be well to our north during the daylight hours.

SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/
Overall, the trend remains for somewhat lower temperatures and somewhat lower humidity levels with a notable marine influence across our area. Expect low temperatures in the mid 60s to near 70 degrees for Thursday night under mostly clear skies. A light south to southwest wind should prevailing overnight.

By Friday, Bermuda high pressure will remain positioned off the Mid- Atlantic coast. Increasing south to southwesterly flow plus the upper ridge starting to sink farther south will usher a warmer and more humid air mass into the region. Highs on Friday should get solidly into the low to mid 90s, perhaps in the upper 90s within the Philadelphia to Trenton metro area.
Regardless, this appears to most likely be the hottest day of the heatwave through the end of the week. Surface dew points rise into the upper 60s to low 70s, resulting in max heat index values ranging from the mid 90s to near 100 degrees. Given the confidence level for reaching Heat Advisory criteria, and Warning level heat indices appearing unlikely, we have upgraded the Excessive Heat Watch to a Heat Advisory for Friday through Friday night. Additionally, this will be the 4th day of the heatwave in much of the advisory area.

The other aspect for Friday is that a back-door cold front will sag in from the north, likely initiating a few afternoon and evening showers and thunderstorms. Will follow NBM and carry low-end likely PoPs for the southern Poconos and far northern New Jersey, and chance PoPs down to along the I-78 corridor.
Slight chance PoPs continue down to Philadelphia. For areas north and west of the Fall Line, PWATs will be up around 1.75 inches and 0-6 km Bulk Shear will be less than 20 kt. SB CAPE values should range from 1500 to 2000 J/kg. Water loaded downdrafts could cause localized flooding due to potentially slow- moving thunderstorms producing heavy rain, as well as the potential for microbursts. The SPC carries a Marginal Risk (1/5)
for severe thunderstorms north of I-78.

Lows will be a couple of degrees warmer Friday night compared to Thursday night, mainly in the upper 60s to low 70s. Urban areas that don't experience any convection could stay in the mid 70s. Patchy fog may develop Friday night as well.

LONG TERM /SATURDAY THROUGH WEDNESDAY/
Excessive Heat Watch will remain in effect for Saturday and Sunday, mainly based on the cumulative impacts have based on several days of heat and humidity with little, if any, relief at night due to warm overnight low temperatures have.

While high temperatures seem to be trending slightly lower than originally forecast, surface dew points are trending on the higher side given persistent southerly flow allowing low level moisture to build into the Northeast and Mid-Atlantic and the upper ridge sinking farther south.

Back-door cold front through the northern half of the forecast area Friday night remains nearly stationary on Saturday. This situations tend to see the boundary stall out from around the Lehigh Valley southeast toward Trenton and the northern NJ coast. As a result, highs will be in the upper 80s to low 90s for the northern portion of the forecast area, and even along the coasts, highs will be in the low to mid 80s due to flow coming off the cooler ocean waters. Just inland, including the I-95 corridor from Trenton to Wilmington and areas west, as well as Delmarva, highs should get in the mid 90s again. Surface dew points will be in the upper 60s to low 70s. Max heat index values in these areas will be in the upper 90s to low 100s.

A thermal trough sets up over central Pennsylvania and some approaching shortwave energy may initiate some afternoon and evening showers and thunderstorms, with the highest PoPs north and west of the Fall Line. Again, heavy rain and localized flooding possible along with potential for microbursts.

A cold front approaches on Sunday. Southwesterly flow ahead of the front ushers warm and humid air with highs in the mid to perhaps upper 90s and surface dew points in the lower 70s. The temperatures have trended up slightly for Sunday, although this will be conditional based on the approaching front and associated clouds and convection. Will keep an eye on potential severe weather on Sunday. Ahead of the front, SB CAPE values rise to around 1500 J/kg and 0-6 km Bulk Shear will rise to 35 to 40 kt in the afternoon and evening. DCAPE values will be up around 600 to 800 J/kg. PWATs will be up around 2 inches.
Damaging winds and heavy rain possible Sunday afternoon and evening.

Cold front comes through on Monday and may get hung up over the area into Tuesday. With the front over the area, additional scattered showers and thunderstorms possible Monday afternoon.
Highs will be in the upper 80s to around 90, with surface dew points in the mid and upper 60s. Max heat index values will not be much higher than the actual surface temperatures. Tuesday looks to be dry with temperatures a few degrees above normal, topping off in the upper 80s to low 90s.

AVIATION /05Z THURSDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Rest of Tonight...Prevailing VFR for much of the night. Some patchy fog at KACY possible around daybreak, reducing visibilities to MVFR levels briefly. Fog should mix out by 11z though. Everywhere else should stay VFR with south/southwest winds at 5 kt or less. Moderate confidence.

Thursday...VFR Winds increase out of the south to southwest 5-10 knots. More southerly winds expected yet again at KMIV/KACY this afternoon with the passage of the sea-breeze.
Funneling up the Delaware Bay will result in a south/southeast wind at KILG as well. High confidence.

Thursday Night...VFR. Winds out of the south/southwest 5 kt or less. High confidence.

Outlook...

Thursday night through Saturday...Overall, VFR. Afternoon evening SHRA/TSRA with sub-VFR conditions possible at KRDG/KABE/KTTN/KPNE/KPHL Friday and Saturday.

Sunday...Generally VFR. Scattered afternoon SHRA/TSRA may result in sub-VFR conditions.

MARINE
No marine headlines expected through tonight. Winds will be out of the south around 10-20 kt with 2 to 3 foot seas.

Outlook...

Thursday through Saturday...Sub-SCA conditions, though persistent 15 to 20 kt winds may develop at northern NJ ocean waters each afternoon.

Sunday...SCA conditions may develop with S winds 15 to 20 kt with 25 to 30 kt gusts and Seas building to 3 to 5 feet.

Rip Currents...

Thursday...Southerly winds around 10 mph and breaking waves will be around 1-3 feet. Portions of the southern NJ coast will keep an onshore component of the wind, in addition to the Full Moon on Friday. For this reason, have maintained a MODERATE Risk for all New Jersey beaches except Monmouth County. For the Delaware Beaches and Monmouth County, maintained the LOW Risk of dangerous rip currents.

Friday...Similar weather conditions are expected on Friday in addition to the occurrence of a Full Moon. With this in mind, saw no reason to change Rip Risks for NJ/DE beaches from what is currently posted for Thursday.

Rip currents occur often in the vicinities of jetties and piers.
Utilize any guarded beaches if venturing out into the water. For specific beach forecasts, visit weather.gov/beach/phi
