.DISCUSSION...
KEY MESSAGE 1...

Surface high pressure will build in behind a departing cold front
leading to a quiet end to the weekend. Skies will be sunny as
temperatures climb into the 80s. Based on yesterday`s observed highs
under sunny skies, temperatures were increased using a blend of NBM
and NBM 90th percentile. Dew points will be in the 50s to mid 60s,
so despite the warmer temps, it will feel more comfortable than past
days. Most of the overnight period is expected to be dry as well.
The nighttime temperatures will drop into the 60s.

KEY MESSAGE 2...

The start of Monday is expected to be mainly dry, especially for
those further east. Some early morning showers will be possible
ahead of the remnants of an MCS out of the Midwest that will track
east into the region by midday with support of a wave passing
through. As previously mentioned in past discussions, there are
signs of an EML associated with this convection though there is
uncertainty with how far east that will extended. Instability will
range from 500 to 1000 J/kg though with increasing sky cover in the
morning, it may be difficult to get values on the higher end of that
range. Shear will be fairly weak at 25 to 35 kts. Conditions will be
marginal for isolated stronger storms. The main concern on Monday
will be the potential for localized heavy rainfall. Model soundings
show moist profiles with skinny CAPE. PWATs will be 1.7 to 2 inches.
Upshear flow will be weak for part of the day, suggesting the
possibility for slow moving storms. While having a dry day prior
will help, any areas that have received higher amounts of rainfall
in recent days will be most sensitive to isolated hydro issues.

Weak high pressure will briefly build into the region early Tuesday
and bring drier air over the region. The next disturbance will drop
into western NY/PA and clip southern portions of the region Tuesday
with showers and thunderstorms. After a brief lull in activity, a
surface frontal system will approach the region from the north.
Additional showers and thunderstorms will kick off ahead of the
front as an upper level trough begins to dig over the Northeast on
Wednesday. This front will sweep through during the overnight hours
and be followed by drier air. However, with the trough hanging
around, embedded weak waves will support isolated to scattered
showers/storms on Thursday.

KEY MESSAGE 3...

Ensembles are favoring a pattern change at the end of the week as
the trough slides east and the ridge over the Midwest builds in.
There are some uncertainties on timing though, so if the trough is
slower to move out, there would be potential for spotty showers
Friday. Otherwise, drier conditions are favored into the weekend.
The ECMWF has been consistent in the past few longer-range runs with
a system moving through on Sunday as the ridge breaks down while
solutions like the GFS keep conditions dry under the ridge. Given
this, low chance PoPs were introduced for Sunday.

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
Patchy fog and stratus clouds will be around the area through
13z this morning. This will bring occasional MVFR/MVFR Fuel Alt
CIGS to RME, ITH, BGM and AVP. IFR is unlikely to occur this
morning.

By mid to late morning conditions then turn VFR through the
rest of the day and evening at all of our TAF sites. Some valley
fog could return to ELM late in the taf period, before daybreak
Monday morning, depending on if/when mid level clouds arrive.

Winds turn west-northwest and could be breezy between 10-20 kts
at RME and SYR this afternoon. Elsewhere, West-northwest winds
are mainly 5-12 kts this afternoon, diminishing quickly after
sunset and becoming variable/terrain driven overnight.

Outlook:

Monday morning...Remnant rain showers and perhaps rumble of
thunder could approach from the west; otherwise mainly VFR.

Monday afternoon through Thursday...Unsettled pattern with
periods of showers and scattered thunderstorms with associated
restrictions. Restrictions with overnight fog/low clouds are
also possible.
