Synopsis
A surface trough will be located over the piedmont this afternoon
through Sunday. An upper level disturbance will cross the region
this afternoon and early evening, followed by another disturbance
Sunday afternoon.

Near term today and tonight
As of 950 am edt Saturday...

there is a slight risk of severe thunderstorms this afternoon and
evening.

Westerly flow in the mid levels will be increasing to 40-45kt this
afternoon from the mid-mississippi valley east across nc va. At the
surface, surface dew points are now in the lower to mid 60s. With
ample sunshine expected, strong heating will result with
temperatures to peak in the upper 80s to around 90f resulting in
mlcapes on the order of 2000+ j kg. Any approaching, hard to time
disturbance in the increasing westerlies will combine with the
aforementioned parameters to support the development of scattered
thunderstorms late this afternoon and evening, mainly over the
western and northern piedmont into the northern coastal plain.

Considering the expected favorable elevated mixed layer (eml) and
the degree of instability expected, some of the thunderstorms will
become strong with at least isolated severe storms expected. The
main hazards are expected to be large hail and damaging wind gusts.

Areas to our west will have to be watched in the fast flow aloft as
storms upstream may be able to make it east of the mountains
overnight due to the lingering instability and strong steering flow.

Lows tonight in the mid 60s to near 70 (where it does not rain).

Short term Sunday and Sunday night
As of 244 am Saturday...

isolated severe storms possible Sunday afternoon and evening.

While the main focus for severe convection may be more over
tennessee kentucky, a few storms or even short lines of storms may
cross the mountains and develop SE of the blue ridge, into the
piedmont during the afternoon and evening. The development to the se
should be encouraged by strong afternoon heating and resultant
instability again along and east of the blue ridge, with a forecast
maximum of instability over central nc. Dew points in the mid to
upper 60s along with temperatures forecast to reach the mid to upper
80s, will result strong instability over the nc va piedmont east
through the coastal plain. This will be a favorable environment for
strong to locally severe storms again Sunday.

Convection is expected to weaken and decrease Sunday night as the
region gets convectively overturned and or nighttime stabilization
develops. Lows generally in the 65-70 range again expected.

Long term Monday through Friday
As of 350 am Saturday...

a deep mid upper level trough is again expected to develop across
the eastern half of the country next week, with the deep mid upper
low expected to slowly wobble eastward across south central canada
to southeast canada. This will drive another cold front into central
nc on Monday. Afternoon low level thickness values support high
temps above normal for Monday, generally ranging from the mid to
upper 80s NW to the lower to mid 90s se. A cold front driven by an
embedded S W in the cyclonic flow around the deep mid upper low,
will be the focus for strong to severe storms Monday
afternoon evening. With MLCAPE values of expected to range from 1500
to 2500 j kg and deep layer shear on the order of 40 to 50 kts,
expect we will have the potential for supercells with the main
threat of damaging winds and large hail. Thus, SPC has most of our
area in a slight risk for severe storms Monday.

The surface front will settle southeastward and stall and weaken
across eastern portions of nc Monday night into Tuesday. Lingering
mostly diurnal chances slight chances for showers and storms will be
possible from mid to late week as quick moving low amplitude (hard
to time) disturbances move through the l W trough. Temps will
generally be near to slightly above normal during this time frame,
with highs generally in the 80s, lows in the 60s.

Aviation 15z Saturday through Wednesday
As of 950 am Saturday...

a disturbance aloft and a boundary lying across virginia will bring
a chance of thunderstorms to most areas late this afternoon into the
evening. Otherwise,VFR conditions are expected through 12z Sunday.

Outlook: a series of upper level disturbances along the frontal zone
will nudge the front south into the area Sunday. There be a chance
of mainly late day storms on Sunday, and again on Monday through
Wednesday as a cold front slowly approaches from the west and
potentially stalls over the area.

Rah watches warnings advisories
None.

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.
