What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Low pressure near the new jersey coast early this morning will
bring an area of showers across southern areas, which should
push offshore by midday. Another weak weather system may bring
some spotty showers across central and eastern areas this
afternoon. High pressure will bring dry conditions but a bit
cooler temperatures on Friday. Unsettled conditions Saturday,
continuing through early Monday with the chance of showers and
thunderstorms. Dry weather expected Tuesday and Wednesday.

Near term until 6 pm this evening
10 am update...

forecast is in good shape.

Last of showers exiting south coast, which will be followed by
clearing early this afternoon. Still expecting scattered
showers this afternoon as short wave rotates through sne and
combines with sufficient moisture and some instability (cape
around 100-300 j kg). Continuing with 30-40% pops which is in
line with high-res guidance.

Bumped up temperatures a few degrees based upon latest
observations. Many interior spots should reach lower 80s.

Short term 6 pm this evening through 6 pm Friday
Tonight...

expect conditions to be mostly clear away from coastal areas
tonight. E-ne winds will continue with the high to the n, so
low level moisture will remain. Brought in low clouds and fog
especially along the coast, but could push further inland as
well. Should see lower conditions along the immediate coast.

Temps will fall back through the 50s, though may hold on close
to 60 in the urban centers.

Friday...

any coastal fog should dissipate by mid morning or so.

Otherwise, high pressure remains in control with mostly clear
conditions. It will remain cool especially along the coast with
continued onshore winds.

Long term Friday night through Wednesday
* highlights...

- Saturday perhaps not a washout, skirting rains S e
- showers t'storms N W Sunday, sweeping SE into Monday morning
- prolonged dry conditions during the week
- watching weeks-end for additional wet-weather disturbances
* overview...

pattern this weekend should feature above normal precipitable
water. Precipitable water values drop off to near to below
normal levels early next week. Temperatures on the other hand
should remain near normal, except for Saturday, and perhaps
Monday.

Split mid level flow regime should merge into a more unified
flow across much of the towards Monday. It appears likely the
pattern will transition from a potent mid level low over
northern quebec with a weaker cutoff over indiana to start this
weekend, to one which features a more amplified mid level trough
by Monday. This trough should move over the north atlantic
towards the middle of next week.

At the surface, this should mean a low pressure moving through
the great lakes towards northern new england this weekend. While
not a total washout, we will have at least a chance for showers
this weekend. A secondary cold front, along with a mid level
shortwave, should be enough to cause showers to linger into
Monday. This timing may change with later forecasts. Instability
is enough to warrant a mention of at least a few thunderstorms
at times this weekend.

High pressure with drier weather Tuesday into Wednesday.

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.
