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
Very little adjustments were made in the near term despite
warmer trend in guidance with temperatures tonight. After
collaboration with surrounding offices decided against frost
advisory with coverage limited to patchy.

At the surface, high pressure to the west continues to draw
closer as the winds go light wsw to variable tonight. With
subtle warm air advection above the surface tonight, and very
little winds and very dry conditions patchy frost should be
achieved in northern most zones. Otherwise, crystal clear with
lows similar to last night, perhaps just a few degrees warmer
than last night in the coldest locations. A wider spread with
tonight's minimums are expected due to a more textbook
radiational cooling set up.

Short term 6 am Wednesday morning through Wednesday night
Sunny skies and a gradual moderation in temps begins on
Wednesday as SW return flow develops around the high to the
south. Temperatures should warm to slightly above seasonable
levels in the upper 60s to lower 70s. It will not be nearly as
cool Wednesday night with warm air advection pattern getting
well underway.

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 19z Tuesday through Sunday
High pressure remains just southwest of the region through
Wednesday.

Vfr through the TAF period. Winds gradually back to the west-
southwest this afternoon. Speeds remain less than 10 kt through
the period.

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.
