Synopsis
High pressure builds in today and lasts into Thursday. A warm
front approaches Thursday night, then low pressure and cold
front pass Friday. Another weak low passes Sunday, followed by
another frontal system Tuesday. High pressure briefly builds
between each passing system.

Near term until 6 pm this evening
Ridging at the surface and aloft today brings us a sunny day.

Cold air advection will help with breezy gusty conditions, but
high temperatures will still end up above normal - even at
south-facing coasts as wnw winds should be strong enough to
prevent a sea breeze from moving in. Went closer to the warmer
guidance for high temperatures based on forecast temperatures
near the top of the mixed layer along with good mixing on the
downsloping flow.

Short term 6 pm this evening through 6 pm Thursday
Mostly clear skies and light winds tonight will result in good
radiational cooling conditions across outlying areas, where lows
could dip to into the upper 30s in some spots. Elsewhere,
temperatures drop into the 40s, except around 50 in the city.

Clouds increase during Thursday ahead of a warm front. Models
have trended earlier with the threat of showers ahead of the
front, so have gone with low chances of showers for most spots
by the end of the afternoon. Instability is lacking, so no
mention of thunder. High temperatures expected to be within a
couple degrees of normal.

Long term Thursday night through Tuesday
Some differences are noted in amount of phasing between northern
stream and southern stream shortwaves Thursday night into Friday.

However, there does appear to be better agreement in global models
when compared to previous runs.

Warm frontal precip may impact the area early in the evening, with
perhaps a break in the rain for the remainder of the night Thursday
night. Then as trough approaches, deepening moisture and stronger
lift will allow for increasing coverage of showers Friday. Warm
front remains close to the coast, and sfc low likely develops around
the triple point of the warm front, occluded front extending north
to parent low, and cold front extending south. This triple point low
passes nearby late Friday, deepening as it moves northeast. This
scenario looks closer to previous ECMWF run. For Friday, expect
showers to prevail, with a rumble of thunder possible due to weak
elevated instability above the low level inversion.

The showers taper off Friday night as drier air gets ushered in
behind the deepening low and cold front. Gusty winds and dry
conditions can be expected into Saturday.

These dry weather conditions will persist between the departing
trough, and fast moving downstream shortwave. GFS is advertising a
stronger upper shortwave, and deeper sfc low reflection for Sunday
as this moves through compared to canadian and ecmwf. Best chance
for showers will be Sunday, then dry conditions move back in behind
this system. Downstream trough approaches, and upper flow will
become nearly parallel with cold front that passes Sunday. As such,
more rain could move back in as air lifts over this front by
Monday night or Tuesday.

Overall, chances for rain followed by brief breaks in the rain is
expected during this time frame.

There will be minor fluctuations in temperatures, but in general,
temperatures should remain within a few degrees of climo through the
period.

Aviation 08z Wednesday through Sunday
A cold front passes through the terminals 08z to 10z with any
widely scattered showers ending, and SW winds shifting to w.

High pressure build in from the west through the TAF forecast.

Vfr.

S-sw winds 5-10kt shift to w-nw behind the cold front with gusts
developing 12z to 13z, gusting 20-25 kt. Gusts diminishing and end
23z to 00z, and winds become NW to N less than 10 kt. Winds will be
around 310 magnetic especially this afternoon.

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.
