AREA FORECAST DISCUSSION
National Weather Service Binghamton NY
527 PM EDT Fri Jul 5 2019
.SYNOPSIS...
Warm and humid conditions persist into the weekend, with
showers and thunderstorms possible this afternoon and more
likely for Saturday. High pressure makes a return, Sunday to
Tuesday, with dry weather.
&&
.NEAR TERM /THROUGH SATURDAY NIGHT/...
Showers and storms have developed along the lake breeze this
afternoon, just west of our forecast area. Expect this area of
convection to persist and eventually push eastward into the
Finger Lakes Region later tonight. Very efficient rainfall is
occurring with these storms, with warm cloud depth over 12K feet
and long skinny CAPE with PWATs near 2". Flash flood guidance
is about 2"/hr, so it is possible that we see localized flash
flooding. A look at mesoscale modeling is narrowing our focus to
the Finger Lakes region southeast into Bradford county this
evening with both models showing an axis of 2-4 inches of rain.
Already several locations in Steuben county are approaching
FFG. Training of showers and thunderstorms is also occurring.
With these concerns in mind we have issued a flash flood watch
for the Finger Lakes region that runs through midnight. Further
east, showers/storms will be much more isolated, with very
little forcing in this area, but still could see isolated storm
with heavy rainfall.
Flash flood potential looks higher for tomorrow, as storms
become more widespread as a cold front pushes through the
region. A very similar airmass will be in-place, so have added
the mention of heavy rain into the forecast for tomorrow with
storms being more numerous. Latest BUFKIT forecast soundings
show potential for slow moving/back-building cells out ahead of
the front, with short Corfidi vectors. Although the potential
for flash flooding is higher tomorrow, still tough to pinpoint
any one location as more susceptible as FFG is around 2"/hr
just about everywhere. Due to that higher FFG, thinking
localized flash flooding is more likely than seeing anything
widespread in multiple locations. Will continue to highlight the
threat in the HWO for now, and if confidence grows on any
particular location, then a short fuse flash flood watch could
be issued at a later time.
Front exits the region tomorrow evening with high pressure
building in behind it and drier conditions.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY/...
Front settles over southern PA on Sunday. Models differ on what
happens next but it seems like some form of inverted trough
develops north of the front and will continue the unsettled
weather in our NEPA zones into Monday. NAM is the drier of the
models while the EURO has better developed convection,
especially with heating later in the day. Across the NY zones,
forecast remains dry as high pressure and drier air builds in
from northern NY and Canada.
Temperatures for the short term will be a bit below normal with
the northerly flow, and clouds over the southern zones.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
High pressure finally builds in Monday night at the surface, and
ridging builds aloft. This will keep the forecast area dry and
seasonable for much of the long term. Short wave is forecast to
break down the ridge at the end of the period and push a couple
of fronts into the area. This will bring a good chance for
showers and thunderstorms on Thursday.
&&
.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
140 pm update...
Scattered showers/storms possible this afternoon across Finger
Lakes Region. SYR will have greatest shot to see restrictions
from showers/storms this afternoon and evening and ELM may also
see brief restrictions for storms this evening. Further east,
showers and storms will be isolated and not enough confidence to
put in the forecast at this time.
Storms will become more widespread as a cold front pushes into
the region tomorrow. SYR/RME/ITH/ELM will have best chance to
see any restrictions from showers and storms late tomorrow
morning and before 18Z, as BGM and AVP may not see anything
until after 18Z tomorrow.
Outlook...
Saturday afternoon through Saturday night...Mainly VFR, but
restrictions expected at times in showers and thunderstorms.
Best chance for showers and storms will be Saturday afternoon
through early evening.
Sunday through Tuesday...VFR conditions expected with high
pressure moving back into the region. Possible restrictions due
to early morning valley fog.
