Marine Weather and Tides
Old Greenwich, CT

Version 3.4
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
Weak high pressure builds in through tonight, followed by a
cold front crossing the area Wednesday and Wednesday night as
an area of low pressure passes to our south. High pressure then
builds to the northeast through Thursday night, then gradually
retreats to the northeast into Saturday. This allows a warm
front to lift through the area late Saturday, followed by a cold
front that crosses the tri-state Sunday. High pressure then
builds into the area through Monday.

Near term until 6 pm this evening
Just a few minor adjustments with this update to reflect the
latest trends in observations. The forecast remains on track.

The region will be under a NW flow regime today. The result
will be dry weather and decreasing cloud cover through the day.

The NW flow should preclude a seabreeze, as a result, coastal
locations will be warmer than they were yesterday, however
inland locations should be around 5-10 degrees cooler than
yesterday. Highs should generally be in the mid-upper 80s,
except around 80-lower 80s in the higher terrain across the
northern tier of the CWA from W passaic county through interior
sw ct.

There will be moderate risk of rip currents at atlantic ocean
beaches into this evening.

Short term 6 pm this evening through Wednesday night
Nw flow continues tonight, with continued dry weather and
minimal cloud cover. Lows should run around normal, except
upwards of 5 degrees above normal in and immediately adjacent to
nyc.

The flow aloft flattens to zonal on Wednesday as a closed low
over quebec pushes farther s. An associated 700-500 hpa
shortwave approaches from the west late Wednesday - possibly
bringing some spotty showers to mainly western zones. Highs
Wednesday should be around normal levels.

The axis of the closed low pushes towards the region Wednesday
night, this should trigger some mainly scattered showers and
possibly a rumble of thunder as well. Precipitable waters
increase to 1.75 to around 2" Wednesday night, so there is the
potential for locally heavy rainfall as well. Refer to the
hydrology section of the afd for details. Lows Wednesday night
should run a few degrees above normal.

Long term Thursday through Monday
Nw flow sets up aloft Thursday as the axis of the mid-upper
level trough slides to the east. Could see some linger showers
or thunderstorms early, otherwise it should be dry with
decreasing cloud cover.

Deep layered ridging builds into the area from Thursday night
through Friday night, with associated subsidence keeping things
dry with minimal cloud cover.

The ridging breaks down over the area on Saturday as a northern
stream shortwave trough approaches from the west. This could
bring some spotty rain to the area before the associated surface
warm front lifts to the north by late in the day.

The shortwave trough passes to the north Saturday night, with
any showers confined mainly to the evening.

There is some question on the exact timing and strength of the
next northern stream shortwave trough. For now it appears it
passes by , mainly to the north on Sunday - so limit chance of
showers and thunderstorms to mainly N interior zones with slight
chance pops elsewhere. There is some chance this shortwave
passes by dry, as the best dynamics are progged to stay to the
n of the region.

Nw flow then returns into early next week, with cooler and less
humid conditions currently forecast for next Monday.

Temperatures Thursday-Saturday should be within a few degrees of
either side of normal. Sunday should see highs running above
normal and Monday should see temperatures return to near normal
and possibly below normal.

Aviation 14z Tuesday through Saturday
High pres builds towards the area this afternoon through wed.

Vfr thru the TAF period. NW flow backing to the N thru the day
becoming light tngt. Winds become light onshore on wed.
