Synopsis
High pressure remains over the mid atlantic region through the
remainder of the week with temperatures gradually moderating.

Near term until 6 am Wednesday morning
The current surface analysis shows ~1028mb high pressure
centered over the low potomac river. The sky is clear, except
for a band of mid high clouds skirting the albemarle sound and
some stratocumulus just offshore. The high remains over the region
tonight resulting in ideal radiational cooling conditions with
clear, cool, and dry conditions expected. Lows tonight will
generally be in the mid upper 30s for rural inland locations,
with low mid 40s for coastal SE va NE nc. Frost should be
widespread enough early Wed morning across rural outlying
locations of the piedmont to warrant a frost advisory. Went with
a frost advisory from mecklenburg to powhatan to caroline county
after coordination with our neighboring offices.

Short term 6 am Wednesday morning through Friday
High pressure remains over the region Wednesday thru Friday as
the airmass gradually moderates. Sunny clear and dry conditions
will continue. Highs Wednesday range from 65-70f followed by
highs Thursday of 70-75f. Highs Friday will reach the mid 70s
for most places. Lows Wednesday night will generally be in the
40s. Lows Thursday night will range from the mid 40s inland to
the low mid 50s coast.

Long term Friday night through Tuesday
High pressure gradually pushes off the coast over the weekend.

Temperatures will continue to moderate with sky conditions no
worse than partly sunny. Much disagreement in the models by the
first of next week with respect to the arrival of the next cold
front. ECMWF is much wetter than the GFS with its deeper trough
aloft and a potential sfc low developing along the coast. Will
show chance pops Monday Tuesday, then another potential cool
down by the middle of next week. Highs sat-mon in the mid-upr
70s except 70-75 along the coast. Lows Sat nite 50-60. Lows sun
nite in the mid 50s to low 60s. Lows Mon night in the upr 50s to
mid 60s.

Aviation 00z Wednesday through Sunday
High pressure will dominate the region tonight into this
weekend providing dry wx with a mostly clear sky and mainly
light winds. The next cold front will affect the area Mon and
tue.

Marine
High pressure continues to push into the region and the gradient
along the coast continues to weaken along with the gradual
ending of the cold advection. This all spells the weakening of
the wind fields. So while the NE winds continue, but they will
continue to diminish in intensity. Seas are also dropping as
well with the relaxing wind field. So with this package will
drop the SCA headlines across the lower ches bay, currituck
sound and the 2 northern coastal zones. The remains SCA flags
will continue through 00z tonight and midnight, but conditions
may improve so that the advisories can be dropped early.

The high becomes centered over western and central virginia
tonight and the high remains entrenched over the region through
the remainder of the week into the weekend. There is a weak
front that tries to move through the northern waters on Friday
afternoon, which would turn the winds to the NW briefly and may
kick winds up to the 10 - 15 kt range, but otherwise expect
light winds and seas from Wednesday through the weekend.

Equipment
The kakq radar will be down through Wednesday, october 18th for
radome repairs.

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.
