Synopsis
High pressure remains in control through the
weekend. As it passes east early next week, rain chances
increase as low pressure and a cold front approach.

Near term until 6 am Wednesday morning
Temperatures have fallen over the past two hours faster than
previously forecast with clear skies and light winds, so have
updated temperatures to reflect latest trends. Noting the warm
advection aloft, still feel that widespread frost is not likely
overnight, thus after collaboration with surrounding offices,
have decided against a frost advisory.

Short term 6 am Wednesday morning through Wednesday night
As high pressure moves in, a southwest flow will develop leading
to a gradual warm up in temperatures beginning on Wednesday.

Temperatures should warm to slightly above seasonable levels in
the upper 60s to lower 70s with plenty of sun.

Long term Thursday through Tuesday
Aloft, initial weak shortwave passes with no impact on our weather.

Ridge builds late this week and through the weekend. Thereafter,
differences in the global models arise with regard to timing and
eventual strength of upstream trough as it moves toward the east
coast Monday and Tuesday.

At the surface, a weak cold front passes Thursday night into early
Friday. Otherwise, high pressure builds late this week, and passes
off the coast this weekend. A stronger cold front approaches from
the west Monday and Tuesday. Again, due to differences in the models
aloft, differences are noted on progression of the front, and any
associated waves of low pressure that may ride along it.

Higher confidence in an increase in clouds Monday and Tuesday, along
with increasing rain chances, mainly beginning Monday night into
Tuesday.

In the Thursday through Sunday time frame, expect abundant sunshine
along with daytime highs averaging around 5-10 degrees above normal.

In fact, these above normal temperatures continue Monday and Tuesday
as well in spite of the increase in clouds.

Aviation 00z Wednesday through Sunday
Vfr as high pressure remains to the south of the region through
Wednesday.

Light ssw flow at city terminals overnight with light and variable
winds elsewhere. Winds briefly shift to the NW in the morning and
then back to the sw-ssw in the afternoon. Southerly sea breezes are
possible at coastal terminals in the afternoon.

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.
