Synopsis
A weak cold front will sink south through the region late this
afternoon into tonight. The front will drop into the carolinas
Sunday, and then return north as a warm front Sunday night.

Another cold front approaches from the northwest on memorial
day.

Near term through tonight
Current GOES wv imagery reveals a shortwave trough tand
associated surface low pressure tracking across tn and ky this
morning. Mostly clear locally this morning with temperatures
warning rapidly with mid 70s to near 80 by 10 am. May need to
bump up afternoon highs a degree or two. The trough will dig
ese today, with the surface low following suit and tracking
across central SE va late this aftn through the evening.

Conditions remain dry through midday and even into later
afternoon at the coast, before the chc for showers tstms
increases during the aftn into the evening. Storm develop acorss
central va later this afternoon and then race east and southwast
towards the coast.

0-1km MLCAPE values are progged to reach 1000-1500 j kg, with a
decent mid upper level speed MAX resulting in 0-6km bulk shear
of 40-50kt. Downdraft potential is rather high along with hail
and lightning potential given thermal profiles. Severe
thunderstorms are possible this aftn and evening with areas
along and S of the i-64 corridor in a slight risk area. The main
threats are damaging wind gusts and large hail.

Mostly sunny this morning, then becoming partly sunny, and
mostly cloudy late. Forecast highs range from upper 70s to near
80 over the ERN shore to the low mid 80s inland W of the bay.

The chc for showers tstms diminishes nw-se overnight tonight
with lows generally in the 60s.

Short term Sunday through Monday
The initial shortwave trough pushes offshore Sunday morning,
with shortwave ridging building over the mid-atlantic. The
surface cold front drops into the carolinas Sunday with N ne
flow developing across the region in the wake of the mid-level
trough and surface cold front. Variably cloudy with some patchy
morning stratus or fog possible. Cooler over the ERN shore with
highs in the low mid 70s and locally upper 60s at the immediate
coast. Highs will generally be in the upper 60s from the wrn
shore of the bay through coastal SE va nc nc, with low mid 80s
for central SRN va and interior NE nc.

The surface boundary returns newd into the region late Sunday
aftn into the evening and early overnight hours. This will
combine with another shortwave trough resulting in an increasing
possibility of showers tstms during the evening and overnight
hours. 0-6km bulk shear rapidly increases to 35-45kt after 00z
resulting in a chc of a few strong to marginally severe tstms
mainly during the evening. Mostly cloudy with lows in the 60s.

A cold front will be crossing the mountains Monday morning, and
then continue ewd Monday aftn. Additional showers tstms are
expected memorial day aftn evening. There is some model
disagreement with respect to coverage, so pops will remain
30-50%. Increasing wsw flow aloft ahead of a trough digging
across the great lakes will yield 0- 6km bulk shear values of
40-50kt. This will combine with 1000-2000 j kg of 0-1km mlcape
resulting in the potential for severe thunderstorms. Partly
sunny then mostly cloudy on memorial day with highs ranging
through the 80s, with the potential for near 90 se, and 70s
along the atlantic coast of the ERN shore.

Long term Monday night through Friday
A frontal boundary will push south of the area Tue morning, with
weak high pressure providing mainly dry wx for Tue aftn thru wed.

More unsettled wx with chcs for showers or tstms then expected
wed night thru fri, as a frontal boundary will linger over the
region or acrs the carolinas. Highs will mainly range fm the
upper 70s to mid 80s thru the period, with lows ranging fm the
upper 50s to the upper 60s.

Aviation 15z Saturday through Wednesday
Vfr conditions prevail this morning and into early this aftn.

Scattered showers and tstms return to the region later this
aftn, becoming most probable from about 18-20z through
00-03z sun. There is a potential for some strong storms with
strong wind gusts being the main concern (and brief heavy
rain reduced vsby).

Otherwise, the wind will shift to the N NE later tonight and
become E SE during the day Sunday. Some lower CIGS MVFR-ifr
conditions are possible Sun morning. A chc for showers tstms
returns Sunday evening night and again Monday aftn evening.

Minimal chcs for aftn evening showers tstms persist into
Tuesday and Wednesday.

Marine
Latest surface analysis places a weak ridge of high pressure over
the water with an area of low pressure over the ohio valley. Winds
are generally light and variable, with speeds at or below 10 knots.

Waves ~1 foot and seas 1-2 feet. The ridge axis slides offshore this
morning as low pressure approaches from the northwest. An associated
cold front reaches the waters this afternoon. Flow becomes south to
southeast around 10 knots. Seas 2-3 feet. Low pressure pushes across
the waters tonight as the front drops over north carolina. Flow
becomes northerly at 10-15 knots. Low pressure stalls offshore
Sunday as high pressure nudges in from the northeast. Flow becomes
onshore through Sunday evening at 10-15 knots. The next area of low
pressure lifts over the eastern great lakes region Sunday night and
into eastern canada on memorial day. A trailing cold front reaches
the waters late Monday into Monday night, stalling along the coast.

The front washes out as high pressure slowly builds in from the west
through Wednesday. Winds generally at or below 15 knots. High
pressure prevails through the end of the work week.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
