Synopsis
A large low pressure system will slowly slide east through the
weekend and will weaken as it does so. High pressure will build in
south of the region Tuesday. A cold front may slowly progress
through the region starting Wednesday.

Near term until 6 pm this evening
Slow improvement in conditions from SW to NE this afternoon.

Skies become partly sunny in the W this afternoon. It will
remain mild and humid, but not as warm as Friday. Some lingering
showers possible as well. Highs will mostly be in the low 70s.

Short term 6 pm this evening through 6 am Sunday
It will remain unsettled tonight with the upper low circulating
across the area and a slowly drying lower atmosphere in place.

Skies will be partly to mostly cloudy and there will be still a
slight chc for a shower or two. It will remain mild however with
lows mostly in the 50s. A little patchy fog is also possible in
rural areas, especially if the clouds break up more than
presently expected.

Long term Sunday through Friday
Due to the current weather, the long term was not updated on
this shift. It will be updated later today. The extended starts
off unsettled as an upper level cut off low spins across the
eastern us and eventually tracks to the northeast and into new
england late Monday. Meanwhile, at the surface, low pressure
will slowly move through the mid- atlantic and cross our area
Sunday night into Monday. High pressure will nudge its way into
the area late Monday before sliding to our south on Tuesday.

Another surface low pressure system will approach the region
around midweek. Beyond midweek, the guidance diverges and shows
varying solutions from high pressure over the region to having a
slow moving boundary as we head into the end of the week.

Overall, the period looks showery with the exception of
Tuesday, and possibly some areas on Monday. With so much
uncertainty after midweek, confidence is too low to state that
any day will dry. Not much in the way of cold air moving into
the region, although Monday will likely be cooler than most days
of the extended. Depending on how the models resolve the end of
the week, there is still the potential for some cooler air to
arrive. The cooler days look to be close to the climatological
normals for april with the rest of the period remaining above
normal.

Concern remains for some minor flooding on the eastern shores

continue to monitor. However, latest trends indicate the high
tide should fall just short of advisory levels.

Finally, have seen some minor flooding on the northern shores
of barnegat bay and associated back bays today. With prevailing
southerly flow continuing, expecting more of this through today.

The current coastal flood statement remains in effect through
the next high tide later this morning.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
