Area Forecast Discussion
National Weather Service Wakefield VA
150 PM EDT Mon Jun 5 2017

.SYNOPSIS...
Low pressure over the eastern Great Lakes will move southeast
today...and deepen over southern Virginia by late afternoon. A
slow moving cold front will cross the local area tonight. The
front will stall over the Carolinas Tuesday as an upper level
area of low pressure lingers near the local area through
Thursday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Current analysis indicating ~1005 mb sfc low pressure centered
over upstate NY, with a sfc trough extending SSW to the central
Appalachians. Water vapor imagery depicts strong upper level
low centered N of the Great Lakes, with shortwave energy moving
through the base of the trough, one pushing SE through northern
Indiana/northwest Ohio late this morning, and another shortwave
farther south over Kentucky moving east. Models suggest these
two features phase to some extent between 18Z-00Z/this aftn
early evening. Coinciding with precipitable water values of
1.50" to 1.80" (well above avg), and a deepening sfc low/meso-
low over southern/southeast VA, expect coverage of precip and
potentially for heavy rain to increase during this period. QPF
amounts through tonight will avg 0.50" to 1.00" NW 1/2 of the
CWA, to 1.00" to 1.50" over southeast VA and northeast NC (with
locally higher amounts possible all areas in embedded tstms). Enough
instability for isolated to scattered tstms N, and a higher
coverage/probability of tstms over the southeast (where higher
instability will reside). Shear generally too weak for anything
strong/organized, perhaps an isolated strong storm possible from
about 20-00Z over the far south/southeast (SPC has this area in
a marginal risk for today). Remainder of the CWA is just in
general thunder. Highs in the in the low to mid 70s NW to the
mid 80s in northeast NC.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
Cold front will push S and E of the entire FA Tue
morning...resulting in lowering PoPs by late tonight
(NW-SE)...then VRB clouds and possible ISOLD SHRAS (due to an
upper level low approaching from the NW) Tue. Cooler Tue with
highs in the l-m70s on the eastern shore to mainly 75-80F
inland.

The combination of upper low pressure lingering over the NE
states/srn New England, and sfc low pressure off the SE and Mid
Atlc coasts will result in a partly-mostly cloudy sky and ~20%
PoPS Wed. Relatively cool with highs u60s NE to l-m70s
elsewhere.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
The combination of upper low pressure lingering over the NE
states/srn New England, and sfc low pressure areas tracking NE
off the SE and Mid Atlc coasts, will result in a partly to
mostly cloudy sky and a slgt or sml chc for pcpn Wed night into
Thu evening. High pressure will then build over the area and
off the coast for later Thu night into Sat morning. A trough of
low pressure will approach and move acrs the area late Sat aftn
into Sat night, possibly triggering isolated or sctd
showers/tstms. High pressure will re-establish itself off the
coast for Sun. Highs in the lower to mid 70s Thu, in the mid 70s
to near 80 Fri, in the upper 70s to mid 80s Sat, and in the 80s
Sun. Lows in the mid 50s to lower 60s Wed night and Thu night,
in the lower to mid 60s Fri night, and in the 60s Sat night.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Deteriorating aviation conditions this afternoon across SE VA
and NE NC as the atmosphere destabilizes ahead of a cold front
pressing SE. Main impact from thunderstorms will be brief
periods of MVFR-IFR CIGs/VIS in moderate to heavy rainfall. SW
winds generally to 10-15 kt will become more NNW in the
post-frontal environment this evening and overnight.
Precipitation will diminish slowly tonight, however MVFR-IFR
CIGs are expected to linger into Tuesday morning. High pressure
builds into the region from the upper Midwest late tonight/early
Tuesday. An upper level trough will keep the threat for isolated
to scattered showers at all TAF sites through at least Thursday.

&&

.MARINE...
The SCA over northern coastal waters has been cancelled as seas
there are expected to top off at 4 ft for the remainder of the
morning.

Previous Discussion...
SCA headlines remain in effect through late morning for 15-20 kt
winds over the Bay due to a tightening pres gradient ahead of an
approaching cold front, and for seas up to 5 ft out 20 nm over
northern coastal wtrs. Sub-SCA conditions thereafter for the
remainder of the day and night as the cold front slides through
the region and little in the way of CAA behind the front. NW/N
winds Tue avg 10 kt with 1-2 ft waves over the Bay and 2-4 ft
seas over coastal wtrs. A couple areas of low pressure will then
track northeast off the Southeast and Mid Atlc coast Tue night
through Thu, resulting in N or NE winds 10-20 kt and seas
building to 4 to 6 ft.
