Area Forecast Discussion
National Weather Service Binghamton NY
111 PM EDT Mon Jun 5 2017

.SYNOPSIS...
Periodic showers and thunderstorms will prevail through
Tuesday as a storm system impacts the region today, then
becomes stationary over the region. Warmer and drier weather
will return towards the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
1000 am update...
Not a lot of change from the forecast with the update this
morning. Just trying to give a bit more detail to the forecast
using the latest high res model guidance (mainly NAM3km and
HRRR) which seem to have a decent handle on the convection
rolling along the srn shore of Lake Ontario. Still expecting a
more widespread area of convection to develop by early to mid
afternoon (1-3pm) over wrn and w-central NY and track to the
east into the early evening hours. Modest low level lapse rates,
dry air entraining into the mid levels, and around 1000-1200
J/kg of Downdraft CAPE point to the threat of gusty winds within
the storms. Sufficient CAPE in the hail growth zone, deep layer
shear around 50 kt and wet bulb zero heights around 9kft point
to the potential for large hail. Saturated soils and plenty of
low level moisture (sfc dew points around 60 deg F) elevate the
threat for flash flooding, but storms should be fairly
transient which will limit the extent of hydro issues. Still not
concerned with the potential for tornadoes as low level shear is
very weak.

430 AM EDT Update...
Just a couple of showers are still present over the area this
morning, but over the next couple of hours expect all activity in
cntrl NY and ne PA to end. The warm front that moved over the
region yesterday is now stationary and is located over central
NY. This has allowed sfc temps to hold fairly steady so far this
morning ranging in the uppr 50s to low 60s. Dew points are near
saturation due to copious amounts of low lvl moisture. The next
storm system to impact the region is located over the great
lakes, and we currently have zonal flow aloft. The mid-lvl low
is also just to the NW of NY, with little impact attm over the
area.

Dense fog has developed over portions of NY/PA due to abundant
amounts of low lvl moisture and a slight inversion over the region.
The fog should mix out fairly quickly after sunrise this morning as
the uppr level low will start to dig southward across the great
lakes the and the mid-lvl low will shift further east.Sfc temps
are forecast to range uppr 60s to low 70s today.

Showers and and thunderstorms will likely develop early today
as high dew points are present along with sfc warm temps. This
will lead to destabilization most likely along the Finger Lakes
region. Expect these showers to be scattered in nature. This
afternoon a shortwave will be ejected over the region which will
force a cold to move across the area. More organized showers
are possible along this frontal boundary. During the afternoon
hours MLCAPE could rise to around 1000 J/KG, 0-6 KM Bulk Shear
is projected to be around 45 Knots, the upper level dynamic
support large hail growth, and with dry mid-lvl air, this
suggests the possibility of strong downdrafts. Thus, large hail
and strong winds today is the main threat. The threat for severe
weather could start as early as 17Z and last through 02Z.
Showers and an occasional rumble of thunder is possible through
the night. Monday's lows will be in the low to mid 50s.

On Tuesday the sfc low will drift south and this will increase the
chance of showers as the flow becomes NW. Showers are likely
throughout the whole CWA, however the best chance for showers will
be I-81 and east. Sfc temps will range in the uppr 50s to low 60s
Tues afternoon.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
345 AM Update...
Showers gradually diminish Tuesday night, yet scattered
diurnally-driven showers can still be expected Wednesday
through Thursday due to very cold pool of air aloft in vicinity
of upper low. Cool east-northeast flow in the lower levels will
depress temperatures to 10-12 degrees below climatology for
highs Wednesday. Some moderation - up about 5 degrees - will
occur Thursday as low level flow becomes variable, yet the upper
low will also drift directly overhead posing a bit of
instability aloft. So there will be a slight chance of thunder
in addition to scattered showers Thursday.

&&

.LONG TERM /FRIDAY THROUGH SUNDAY/...
Approaching wave and surface front finally begins to kick the
old 500mb low out of the area later Thursday and Friday. So,
the chance of mainly afternoon showers and thunderstorms will
lessen and daytime highs will rise. Of course, the approaching
front will trigger another chance of showers and storms on
Saturday, but system is progressive and should clear the area
near the end of the period.

&&

.AVIATION /18Z MONDAY THROUGH FRIDAY/...
Showers and thunderstorms are developing over wrn /w-central NY
and far nrn PA early this afternoon and will likely expand in
coverage and intensity through 00Z. Flight conditions will
range from VFR to MVFR in TS with brief gusty winds and locally
heavy rain possible. Will likely see IFR restrictions later
tonight with another round of rain showers by Tuesday morning
and ceilings only improving to fuel alternate required or MVFR.

Winds will remain light and variable through the forecast
period. A gust to 30 kt or greater is possible if a thunderstorm
impacts a terminal.

Outlook...

Tuesday night...Restrictions likely in rain showers.

Wednesday-Thursday...Restrictions possible in morning fog,
showers through the day...and afternoon thunderstorms.

Friday...Restrictions possible in showers and storms.
