Synopsis
High pressure settles across the deep south today, and then
gradually slides off the southeast coast Saturday and Sunday. A
cold front crosses the region Monday night into Tuesday morning.

Near term until 6 pm this evening
Forecast mainly on track at this point. Have made only some
minor edits per latest obs.

Midday surface analysis places 1030mb high pressure centered
over the deep south gulf coast. Aloft, the trough responsible
for the 1 17-18 snow event is now well offshore with quasi-zonal
flow over the mid-atlantic.

High pressure remains over the deep south through this evening.

Sunny with a light SW breeze and moderating temperatures through
the afternoon. Mixing will be limited today, especially for
locations such as the SW piedmont and coastal NE nc where
melting snow will still be a factor. High temperatures range
from the mid upper 40s for the ERN shore, coastal SE va NE nc,
and the SW piedmont, with low 50s elsewhere.

Short term 6 pm this evening through Sunday
Surface high pressure will prevail tonight through Sunday with
mostly clear sunny and dry conditions. The initial high will
slide off the southeast coast Saturday. A subtle trough slides
across the northeast Saturday night with a weak backdoor
boundary sliding across the ERN shore. High pressure then
rebuilds across the mid-atlantic Sunday. Lows tonight range from
the mid 20s to around 30f. The airmass will continue to modify
Saturday and Sunday with highs ranging from the mid 50s to near
60f inland piedmont, and in the low mid 50s for the ERN shore
and coastal SE va NE nc. Lows Saturday night will generally be
30-35f.

Long term Sunday night through Thursday
Models remain in generally good agreement wrt the pattern for
the extended forecast period. Anticipated milder spell of wx
will continue into the middle of next week as transition of mjo
through phase 4 toward phase 5. Sfc hi pres and upper level
ridging near the E coast will gradually weaken into mon. By
late mon... Storm system tracking into the WRN great lakes will
push its trailing cold front into the mtns. That front will make
progress across the local area Mon night-early Tue W potential
shras (though 00z 18 ECMWF remains a tad slower than 12z 18 gfs
attm). Will carry 60-70% pops during that time frame.

Drying clearing out and a bit cooler (returning closer to
seasonal levels) for Tue afternoon-thu.

Lows Sun night mainly 35-40f. Highs Mon in the l-m50s on the
ern shore to the u50s-l60s elsewhere. Lows Mon night mainly in
the l-m40s. Highs Tue in the l50s on the ERN shore to the
55-60f elsewhere. Lows Tue night in the l-m30s. Highs Wed in
the m-u40s on the ERN shore to the u40s-m50s elsewhere. Lows wed
night from the u20s NW to the m30s se. Highs ranging through the
40s.

Aviation 18z Friday through Wednesday
High pressure builds across the deep south today into tonight
resulting in a SW wind AOB 10kt under a clear sky, withVFR
conditions to prevail through the 18z TAF period and beyond.

Outlook: surface high pressure gradually settles off the
southeast coast Saturday and Sunday with clear and dry
conditions continuing. High pressure slides farther offshore
Monday as a cold front approaches from the w. This cold front
crosses the region Monday night bringing a chc of showers. High
pressure returns later Tuesday.

Marine
High pressure will gradually build into the region during the
day. Current observations show generally west winds of 5 to 15
knots with seas of 2 to 3 feet (waves 1 to 2 feet in the bay).

An increasing gradient on Saturday will lead to an increase in
wind speeds over the waters. Cold water temperatures should help
to limit mixing and keep winds below small craft advisory
criteria on Saturday. Generally quiet marine conditions are
expected to continue through the weekend and into early next
week before a cold front approaches the region Tuesday. Small
craft advisory conditions will likely develop ahead of the front
Tuesday.

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.
