SYNOPSIS. Surface high pressure will be centered northeast of the region today, while a backdoor cold front moves through during the day. A warm front will lift through on Thursday night, followed by a cold front which will move through by Friday night. Bermuda high pressure then becomes established for the weekend, before another cold front likely approaches from the west towards Monday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. At upper levels, a rather sharp ridge will be building in overhead today as troughing from earlier in the week continues to shift away. The upper levels will largely take a back seat in their role on today's weather, however. At the surface, high pressure is centered northeast of New England this morning and will remain there through the day. A weak backdoor cold front was near the New Jersey coast early this morning and will continue to progress southwest through the day, bringing a switch to onshore winds and shielding the region from the hotter air surging in aloft.

Temperatures will be a bit tricky today due to the timing of the front. Thankfully, it is not anything like springtime when frigid ocean waters can cause these type of fronts to produce 20 or 30 degree gradients within a few miles. The warmest temperatures today should be to the west and south, over eastern PA and interior Delmarva, where highs in the mid to upper 80s are expected. Further east, highs should favor the low to mid 80s, with some small drops in temperatures possible from mid afternoon onwards once the front goes through. At the immediate coast, temperatures will remain in the 70s. It will not be especially humid, but the flow off the ocean will lead to a gradual increase in low level moisture especially towards the coast.

Regarding rain chances, have made some changes to the PoP grids for today. Specifically, have added mentionable PoPs (mainly slgt chc but locally up to low end chc) over interior southern NJ, far southeast PA, much of Delmarva, and the Poconos. The air mass remains quite dry, with PWATs around 1.0 to 1.2 inches. These values will come up a bit today, however, especially ahead of the backdoor front. There was a fairly strong signal in most of the 0z CAMs for convective development today in the areas described above. Both instability and shear will be very meager, but low level convergence ahead of the front, and terrain effects in the Poconos, may be enough to spawn some diurnally driven showers. Expect coverage to be isolated at best given weak forcing and weak dynamics, but felt there was enough support to at least add a mention in those areas. The most likely time for these would be mid to late afternoon during the peak heating hours. Should be low impact if they occur at all, and overall this will be a nice day.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/. Any showers during the day will fade quickly with loss of daytime heating. Light onshore flow associated with high pressure to the northeast will continue through the night. Dry weather is expected through the night, but as often happens in onshore flow regimes, a stratus deck is likely to envelop much of the region later tonight. Lows should generally favor the mid to upper 60s, though will be dependent on the timing and robustness of the stratus deck. Going thinking is that it will be fairly extensive, but if it comes in a little later or is less widespread, lows could be a couple degrees cooler than forecast.

LONG TERM /THURSDAY THROUGH TUESDAY/. Overview .

Get ready for the heat. While this period will start off comfortable in the wake of a backdoor cold front, significant changes are expected by the end of the week and the weekend. The upper air pattern becomes quite zonal for the weekend and into next week, with broad, low-amplitude ridging forecast to develop over much of the CONUS. A Bermuda high pattern also develops over the Atlantic. This is a warm pattern for much of the country, ourselves included. Behind a warm frontal passage Thursday night, 850 mb temperatures will range from 17C to 20C for most of the remainder of the period. While not in any sort of record territory, this is more than enough to support an extended stretch of very warm to hot weather, and that is what we will have.

In the fast moving zonal flow, two weak cold fronts will impact the region from late this week into early next week, one moving through around Friday and the other towards Monday. These fronts will serve as modulators of our heat during this stretch. On days when a front is in close proximity or overhead (i.e. Friday) we will be warm and humid but not excessively hot due to increased clouds and better chances for convection. On days without a front over top of us (i.e. Sunday and probably Monday) we will see the numbers really come up, with some heat headlines likely by Sunday and Monday.

It does seem as though we are heading towards a pattern in which fronts tend to wash out and die over top of the region, providing little relief from heat and humidity but allowing for frequent opportunities for showers and thunderstorms as the weak boundaries remain nearby. Something to watch for mainly from a hydro perspective, possibly Friday and Saturday but maybe more so towards next week.

Bottom line with the extended period, once we lose the influence of the backdoor front by the end of this week, it will be warmer than average and quite humid for the foreseeable future. A couple of excessively hot days are possible, as are a few opportunities for showers and thunderstorms, though the overall severe weather risk through the period looks fairly low.

Dailies .

Thursday-Thursday night . We remain behind a backdoor cold front on Thursday. A warm front will begin to approach late in the day, but likely will not move through until overnight. So Thursday looks like a nice day and actually quite cool compared to most recent days as steady onshore flow continues. Highs mainly in the low to mid 80s, a bit cooler right at the coast. The trend has been to slow the progression of things down enough to keep Thursday dry, though cannot totally rule out a late shower/storm across the far west. A better chance for a shower or storm, still mainly to the west, overnight Thursday as the warm front moves through.

Friday-Friday night . Behind the warm front, a cold front approaches from the west on Friday. Not a strong front, and it will be starting to wash out as it approaches, and especially once it passes through. Nonetheless, it will be enough to make Friday perhaps the most unsettled day of the period. Frontal timing will factor into the days' temperatures and precipitation chances, but the recent trends for a slower approach of the front suggest it probably will not move through until Friday night. That would yield a warm and humid day in southwest flow Friday, though cloud cover should cap temperatures mainly in the mid to upper 80s. Scattered showers and thunderstorms are possible Friday into Friday night. With weak dynamics, the risk for severe weather appears low, though some locally heavy rain could be possible.

Saturday-Sunday . The heat builds. As mentioned, the Friday front will be washing out as it moves through the region, and some of the latest guidance suggests it may struggle to clear the region at all. Low amplitude ridging will be developing across much of the mid- latitudes of the CONUS over the weekend, leading to a large area of warmer than average temperatures building to our west. Westerly flow aloft will gradually advect this hotter air into the region over the weekend, and surface temperatures will begin to respond. The potential continued presence of the dying cold front does present a challenge with regards to temperatures. Latest trends are more active convectively for the weekend days, especially Saturday. So if Saturday does end up cloudier with more showers and storms around, it will not be quite as hot, though still warm and humid. Sunday looks to be a better bet for more notable heat as rain chances decrease and 850 mb temperatures climb further, towards 20C. Highs Sunday will push towards the mid 90s, with heat index values over 100C. Heat advisories are possible.

Monday-Tuesday . No significant changes to the upper air pattern. Another cold front will likely approach the region either late Monday or Tuesday, but there is no breaking the back of the warm ridge that will remain present over the central and eastern CONUS and western Atlantic for this period. If there is a day during this stretch that has true excessive heat potential, it is probably Monday ahead of that next front, assuming it holds off on moving through until late in the day. Current forecast has widespread 105 to 107 degree heat index values for Monday. Afternoon storms are possible ahead of the front. If the front is a little faster, Monday would not be quite as hot, but have favored a warmer outcome with this forecast. By Tuesday, we may be post-frontal, but it is also very possible this front too will hang up over us and lead to a continuation of warm, humid weather with daily storm chances from Tuesday into the middle of next week.

AVIATION /08Z WEDNESDAY THROUGH SUNDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Through 12z . VFR. Winds light and variable overall but with the prevailing direction gradually shifting from northwest to northeast. High confidence.

Today . Mainly VFR. Northeast wind around 5 kt this morning becoming easterly then southeasterly at 5 to 10 kt by this afternoon. An isolated afternoon shower with locally sub-VFR conditions is possible especially near PHL, ILG, and MIV, but not expected to be widespread enough to include a mention in the PHL TAF at this time. Moderate to high confidence.

Tonight . Initially VFR. A broken stratus deck with MVFR cigs will likely develop near or after 06z. Southeast wind around 5 kt but winds may turn light and variable or calm. Moderate to high confidence.

Outlook .

Thursday-Thursday night . MVFR possible initially on Thursday morning due to lingering stratus, then turning VFR. VFR continues into Thursday night, but patchy fog or areas of showers with sub-VFR conditions are possible near RDG and ABE. Southeast wind 5 to 10 kt through most of the period, becoming more southerly later Thursday night. Moderate confidence.

Friday-Friday night . Prevailing VFR, but scattered showers and thunderstorms with occasional sub-VFR are likely. Areas of fog with sub-VFR conditions may develop overnight. South-southwest wind 5 to 10 kt becoming light and variable overnight. Low to moderate confidence.

Saturday-Saturday night . Prevailing VFR. Scattered showers and thunderstorms are possible mainly in the afternoon. Southwest wind around 5 kt. Low to moderate confidence.

Sunday-Sunday night . Mainly VFR. Southwest wind 5 to 10 kt. Moderate confidence.

MARINE. Through tonight . Sub-SCA conditions are expected to continue. Winds this morning will shift from northwest to northeast, then become more easterly through the day and east-southeasterly overnight. Wind speeds 10 to 15 kt. Seas 2 to 3 ft.

Outlook .

Thursday-Saturday . Sub-SCA conditions are expected. Southeast winds Thursday and Thursday night becoming south-southwesterly for the remainder of the period. Wind speeds 10 to 15 kt. Seas mainly 2 to 3 ft.

Rip currents .

Winds will turn onshore today and remain that way through Thursday. With wind speeds remaining light and offshore wave heights only 2 to 3 ft, the risk for the formation of dangerous rip currents is expected to remain low today. Wind speeds increase a bit on Thursday, and there is a chance the risk may increase to moderate levels by then, though for now the forecast will maintain a low risk.

EQUIPMENT. The NOAA Weather Radio All Hazards broadcast from Hibernia Park, PA (WNG704) remains off the air due to damage to the antenna during the June 3 derecho. It is scheduled to be repaired on Thursday the 16th.
