.DISCUSSION...
KEY MESSAGE 1...
As of 1:00 AM EST...Current sfc analysis shows areas of high
pressure centered to our south and to our north resulting in
continued large scale upper level ridging. This will help allow for
some periods of clearing in the thick mid and high level clouds,
shown in current GOES satellite imagery, as a weak upper level
disturbance passes though overnight this morning. Southerly flow
will also gradually increase available moisture. Because of the
increased cloud coverage, temperatures in more northern areas are
running slightly warmer with this morning`s lows in these areas in
the mid to upper 40s, while areas south and east where there are
more breaks in clouds will allow for lows to dip into the 30s.

This morning the surface high pressure slides off the Atlantic
coast while a low pressure and upper level trough over the Great
Plains deepens and begins to slowly slide east. It`s associated warm
front lifts though this afternoon. With the peak of the ridge
almost overhead, above normal temperatures are expected with high`s
today in the low upper 50s and low 60s (terrain) and upper 60s
just reaching 70 (valleys). Although, moisture and Td continuing to
increase, it remains limited, and the best forcing looks to the N/NW
of our region. A few light showers due to upsloping could result in
the southern ADKs this afternoon but look to be less than a
tenth of an inch. For the rest of the region, a mainly dry and
pleasant day is expected. Tonight will also be somewhat mild
with lows in the upper 40s and low 50s. Some patchy fog
could develop in the sheltered valley areas tonight as
dewpoints rise. Wednesday, the upper level ridge axis moves directly
overhead and will be the warmest day this week. Model guidance
shows 850 mb temperatures on Wednesday are about 13 to 15 degrees C
and ensemble anomalies showing about +1 to +2 STDEV above normal.
Highs are expected to reach the upper 60s to low 70s (normal high
temperature for this time of year is about 54 F). It will also be
more breezy (wind gusts up to 10-15 kt), especially in the N/S
oriented valleys. Dew points continue to creep up with southerly
flow.


KEY MESSAGE 2...

Thursday, the low pressure system and cold front from the Great
Plains tracks into the western Great Lakes region and occludes.
PWATs rise to around 1 to 1.5" slightly above the 75th
climatological percentile. Showers are expected to the arrive first
in the southern ADKs and areas north and west of I-90 Thursday
morning ahead of the cold front before overspreading the region from
west to east. Western areas, especially the southern ADKs, still
have the best chance to see (40-60%) to see 0.50" or greater of
rain. Latest long range deterministic guidance continue to show the
trend of weakening showers into the afternoon as they track east
over the Capital Region into Thursday evening, outrunning the better
forcing along the front. Here, rainfall amounts Thursday generally
look to be under a quarter inch, and possibly closer to a tenth of
an inch for the Mid Hudson Valley and southwestern New England.
Additional chances for light showers linger Thursday night into
Friday as the front slows and stalls with a wave of low pressure
developing along the front near the New England coast. The latest
ensemble guidance has the best chance (60-70%) for 0.5" or greater of
rain through Friday night looks to be areas south and east of I-90,
closer to the New England coast. There is still some uncertainty as
to the timing of the front and resulting rainfall, Given very
dry weather over the last 2 weeks, any rain will be quite
beneficial with no concerns at all for hydro issues. Even if we
don`t see the steadier/heavier rain with the coastal low system,
scattered showers and cooler weather are still expected as the
upper trough/upper low and cold front tracks overhead Friday into
the weekend.

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
IR satellite imagery shows widespread bkn-ovc mid level clouds
around the region, with ceilings around 10-12 kft for all TAF
sites. Based on satellite trends, these clouds will remain in
place through much of the morning hours today.  Flying
conditions will remain VFR for all sites with no precip through
the day today. Southerly winds will be around 5 kts for all
sites. Some lower clouds around 6 kft will develop by the
afternoon and evening hours as well.

For tonight, clouds will be gradually decreasing through the
overnight hours with light to calm winds. If enough clearing
occurs, some radiational fog could be possible at KGFL, but not
enough confidence to include in the TAF this far out. Otherwise,
it looks to remain VFR with just some leftover cirrus clouds by
the late night hours.

Outlook...

Wednesday Night: No Operational Impact. NO SIG WX.
Thursday: High Operational Impact. Definite RA.
Thursday Night: Moderate Operational Impact. Chance of RA.
Friday: Moderate Operational Impact. Likely RA.
Friday Night: Moderate Operational Impact. Likely RA.
Saturday: Moderate Operational Impact. Chance of RA.
Saturday Night: Moderate Operational Impact. Chance of RA.
Sunday: No Operational Impact. NO SIG WX.
