Synopsis
Bermuda high pressure prevails off the southeast coast through the
Monday. A frontal boundary along the eastern shore will lift back
north as a warm front today. A cold front pushes across the region
Monday night with high pressure returning Tuesday.

Near term /until 6 pm this evening/
Note that all 4 climate sites broke record high min temps for
4/29. See cli section below or rer's.

The current surface analysis shows a backdoor cold front
extending form NRN va across the lower md ERN shore in vicinity
of cge-sby-oxb, with a bermuda high of the southeast coast.

Morning stratus is quickly lifting and scattering with
temperatures mainly in the mid 70s to around 80 and dewpoints in
the upper 60s.

Partly to mostly sunny and hot as the early season heat wave
continues today. 850mb temps between 14-16c results in readings
generally between 85-90 west of the bay. The boundary will
gradually retreat N today and this should allow for highs in the
low/mid 80s over the ERN shore, but remaining in the 70s for the
beaches due to sea-breeze influences.

Short term /6 pm this evening through Wednesday/
Mostly clr tonight except becoming pt cldy after midnight across the
piedmont. Dry as any pcpn stays well west of the fa thru 12z. Lows
65-70 except 60-65 eastern shore.

Models continue to slow the eastward movement of the approaching
cold front from the west Monday. Data suggests a dry morning with
pops increasing mainly along and west of the i95 corridor in the
afternoon. Dry along the coast thru 00z tue. Temps remain well above
normal with highs 80-85 except remaining in the 70s at the beaches.

The cold front crosses the region Monday night and pushes offshore
by 12z Tuesday. Likely pops taper off to chc from nw-se from 06-12z
as drier air arrives from the nw. Cooler with lows from the upr 50s
nw to mid 60s se.

Spc has included the western most akq zones in a mrgnl risk late
Monday into Monday nite. Thinking is for isltd severe hail/damaging
winds from storms crossing the mts during the evening hrs. Also
expect some lclly hvy downpours psbl given the juicy airmass as
pw's apprch 1.5 inches.

Low pressure tracks into ERN canada with high pressure building into
the area tues and wed. A secondary (dry) trof moves north of the
area by 12z wed. Look for dry and cooler conditions. Highs tues
75-80, cooler at the beaches. Lows Tue night in the lwr 50s-lwr 60s.

Highs Wed in the mid-upr 70s except upr 60s-lwr 70s at the beaches.

Long term /Wednesday night through Saturday/
A complex system progged toward the end of the week. Low pressure
develops over the deep south Wed then slowly lifts NE along the
applach mts thurs and fri. Latest models show the system getting
cut off from the main flow and lingering across the region thru
sat. Meanwhile, this system will be able to tap a good amount
of gom / atlantic moisture. The associated warm front lifts
north across the area thurs with chc pops all areas. Enough
moisture for likely pops thurs nite and Fri with lingering pops
fri nite into sat. Most of the pcpn will be convective in nature
resulting in the possibility of another extended period of
rainfall. Stay tuned. Highs both thu/fri in the upr 60s NW to
low-mid 70s se. Lows Thu night mid-upr 50s NW to lwr 60s se.

Highs Sat mid 60s to lwr 70s.

Aviation /14z Sunday through Thursday/
Backdoor cold front located along the va/md line at 12z and may
stay put this morning before moving back north as a warm front
this afternoon. Sunrise special st btwn 1-2k ft will mix out
over the next few hrs as the ssw winds increase. Otw, sct cu
with sct-bkn ci expected thru the day. Ssw winds 10-20 kts.

Outlook: MVFR stratus and visbilities will be possible once
again early Monday morning with a moist airmass in place.

Conditions will briefly return toVFR on Monday before a frontal
boundary crosses the region late in the day. This frontal
boundary will bring the potential for showers and thunderstorms
along with sub-vfr conditions. Dry/vfr conditions are expected
through Wednesday with potentially another system impacting the
region Thursday.

Marine
Broad bermuda high pres allows for 10-15 kt s/sw flow today, with 1-
2 ft waves over the bay and 2-3 ft seas over cstl wtrs. Similar
conditions into tonight with seas building to 4 ft. Next cold front
approaches the area mon, and with a tight pres gradient ahead of the
front, winds increase to 15-25 kt over all wtrs during the day.

Raised headlines over all wtrs, with a gale watch over northern cstl
wtrs and a SCA elsewhere. Gale watch is for 50 percent confidence in
a few hrs of gale gusts, with other areas expected to gust up to 25-
30 kt. Seas build to 6-9 kt over cstl wtrs with 3-4 ft waves over
the bay. These conditions will last into Mon night until the cold
front crosses the wtrs. Winds/waves/seas decrease into Tue as CAA is
weak behind the front, but seas AOA 5 ft may continue through late
tue. Sub-sca conditions everywhere by wed.

Hydrology
Flood advisory continues in mecklenburg county, with vdot continuing
to report numerous roads closed in the kerr dam area, creating ongoing
navigation concerns.

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.
