SYNOPSIS. A weak cold front will continue moving out to sea tonight and Tuesday, with high pressure building in for midweek. A cold front associated with low pressure moving through the Great Lakes region will bring a renewed threat of showers and thunderstorms later Thursday through Friday. High pressure building in from the midwest should then bring increasingly warmer and more humid weather for the end of the week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. A weak cold front lies just offshore with surface high pressure centered over the Great Lakes this evening. Meanwhile, a weak mid-level trough will pivot through the region along with several strong shortwaves through the overnight and into tomorrow. A few light thunderstorms are working their way across the Chesapeake late this afternoon. These are very isolated, with a few rain showers for the Eastern Shore in Cecil and Kent Counties.

With a drying north to northwest flow, surface dewpoints are lowering across the region, falling from the upper 60s this morning to the upper 50s/low 60s this afternoon. As a result, as that trough and shortwaves pass through the region this evening, there will not be much moisture for showers, so no precipitation is expected as thunderstorms remain suppressed across the rest of the region.

High pressure continues to build east tonight. Skies clear out with departure of trough, and northwest winds become nearly calm.

Lows tonight will be in the 60s.

SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/. Surface high pressure continues to build east and will be centered over western New York and western Pennsylvania in the afternoon. Some troughiness will lie over the Northeast, but the base of the trough will be offshore. Some shortwaves will dive into the base of the trough, moving through northern New Jersey.

With northwest flow over the area, conditions continue to dry out due to the downsloping flow. A pleasant day expected, as surface dewpoints fall into the low to mid 50s, with the lowest dewpoints across the Pine Barrens of New Jersey. Highs generally in the mid to upper 80s, yet some places may touch 90 along and east of the urban corridor.

A backdoor cold front will also approach from the north late, and combined with those shortwaves, some showers and thunderstorms may develop well north of the region. Cannot rule out some more showers south of Delmarva. Will keep the local area dry, however, as dry conditions should prevent showers from developing.

A pleasant summertime day with low humidity.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/. A mid-level trough and its associated axis will be exiting the coast late Tuesday afternoon and evening, taking any residual precipitation in the northern portion of the CWA with it. Then mid- level and surface ridging will provide benign weather for Tuesday and Wednesday. With an onshore flow and modest dew point temperatures for this time of year, both air temperature and relative humidity should remain fairly comfortable. Then another frontal boundary associated with a low pressure system moving through the Great Lakes region is expected to bring the chance of showers and thunderstorms to the area late Thursday afternoon through Friday. This front may sag far enough south of the region to provide benign weather during the upcoming weekend, but the combination of a mid-level ridge and southerly flow at the surface will produce increasing warmth and humidity into early next week. An impulse developing along this front may touch off a few showers and thunderstorms, mainly south of the Mason-Dixon line, Sunday night, and scattered showers and thunderstorms are possible again on Monday given an increasingly unstable airmass.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR. NW winds less than 10 kt early, diminishing to less than 5 kt late. A slight chance of a shower at Wilmington through 00Z. High confidence.

Tuesday . VFR. NW winds 5-10 kt. High confidence.

Outlook . Tuesday night through Wednesday night . Mainly VFR. Northwest winds 5 to 10 kt becoming N, then E or SE at the same speeds late Wednesday and Wednesday night. Moderate confidence.

Thursday and Thursday night . Mainly VFR, though chances for showers and storms increase late Thursday afternoon. Brief restrictions possible in their proximity. Southeast winds 5 to 15 kt becoming southerly Thursday night. Moderate confidence.

Friday . Mainly VFR, though chances for showers/storms continue, with brief restrictions possible. South to southwest winds 5 to 15 kt. Low confidence.

Friday Night and Saturday . Mainly VFR. South to southwest winds 5 to 10 kt. Low confidence.

MARINE. Tonight . Ocean seas around 4 feet, diminishing to around 3 feet late. SW winds less than 10 kt.

Tuesday . Sub-SCA conditions with 3 feet ocean seas and S-SW winds 10- 15 kt.

Outlook . Tuesday night through Wednesday night . Sub-advisory winds/seas and fair weather expected.

Thursday through Friday . Sub-advisory winds/seas expected. A chance of showers/storms, with locally higher waves and gusty winds in their proximity.

Friday night and Saturday . Sub-advisory winds/seas expected.

Rip Currents .

There is a moderate risk for the development of dangerous rip into this evening. Breezy southwesterly winds will combine with a medium- period southeasterly swell to yield the continued moderate risk conditions. Surf heights will generally be 2 to 4 feet. By Tuesday, seas will come down by about a foot as offshore flow prevails, so current thinking is that the rip risk will fall to low levels on Tuesday.

EQUIPMENT. The NOAA Weather Radio All Hazards broadcast from Hibernia Park, PA (WNG704) remains off the air until further notice due to damage to the antenna during the June 3 derecho.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
