Synopsis
Cold high pressure lingers across the deep south through
tonight... Before gradually sliding off the southeast coast
through the weekend. Light SW flow will result in dry conditions
through Monday. A cold front crosses the region late Monday
night into Tuesday morning.

Near term through tonight
Latest surface analysis places 1030mb high pressure centered
over the deep south gulf coast. Aloft, quasi-zonal flow now in
place over the eastern half of the conus, resulting in deep
layered w-sw flow aloft, and a mainly clear sky. Afternoon
temperatures averaging low to mid 50s this afternoon, slightly
cooler upper 40s around 50 where deeper snowpack is hanging on
across the i-85 corridor and NE nc.

Lows modify a bit more tonight, with early morning lows
settling into the upper 20s to around 30 for most, slightly
colder low to mid 20s where deeper snowpack exists over far sw
zones.

Short term Saturday through Monday
Surface high pressure will prevail through the weekend 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-res models
indicating potential for some developing low stratus patchy fog
possible toward morning across the piedmont. High pressure then
rebuilds across the mid-atlantic Sunday. Models a bit slower
with the upper trough through Tuesday... And thus expect a dry
day Monday, and into Monday night, as the upper trough lifts
across the great lakes. The airmass will continue to modify
through the period, 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 Monday night through Thursday
A storm system tracking across the southern great lakes by Monday
will push its attendant cold front across the local area during
Tuesday. What remains to be seen is whether this occurs during the
morning or afternoon as there's about a 6-hr difference in timing
between the 12z operational GFS and ecmwf. The 12z GEFS tends to
side more with the ecmwf, and so am inclined to think the fropa
will be during the midday or afternoon hours at this time. Have
high chc to likely pops for most of the area during the 06z-18z
tue period, then pcpn moving out of the entire area by 00z wed.

The remainder of the week should be dry.

Lows Mon night mainly in the low mid 40s. Highs Tue in the low 50s
on the ERN shore to the 55-62 elsewhere. Lows Tue night in the low
mid 30s. Highs Wed in the mid 40s on the ERN shore to the upr 40s to
mid 50s elsewhere. Lows Wed night from the upr 20s n-nw to the
low mid 30s se. Highs ranging through the 40s on thu, then mid 40s
to mid 50s on fri.

Aviation 18z Friday through Wednesday
High pressure builds across the deep south through 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 dominate the weather pattern over the marine area
through the weekend with sub-sca conditions continuing. Light s-sw
winds through this evening will increase to 10-15 kt overnight and
Saturday. Winds diminish again by late sat, becoming n-nw for a time
sat night and Sunday morning. S-sw around 10 kt then prevail again
by Monday. Waves 1-2 ft; seas 2-3 ft. A cold front approaches the
region from the west Monday night then crosses the water on Tuesday.

There are some timing issues that still need to be worked out
amongst the models with respect to whether the front passes first
thing in the morning or in the afternoon. Either way, expect sca
conditions to be possible Tuesday with the fropa.

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.
