.NEAR TERM /THROUGH MONDAY/...
3 am update...

Rain has moved into the entire area now and will continue into
the afternoon as a slow moving warm front moves east. The front
will push through this afternoon. Tonight rain showers will be
lighter as a dying front moves through with limited moisture.
Monday there could be a few lingering light showers from the
southern tier into NEPA. Rainfall totals will be around half an
inch for most but along I90 in Oneida County amounts could be
over an inch. In Oneida a little better low level convergence
and lift. Still nothing to worry about in respect to flooding.

Highs today in the 50s for most but some clearing may get into
the central southern tier and Finger Lakes late afternoon so
highs there around 60. Tonight lows from the upper 40s to mid
50s. Monday more sunshine so highs from the upper 60s to the mid
70s.

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
245 PM Update...

A weak surface trough will slowly exit the region to the east
Monday morning. Lingering showers are expected to remain across
the Twin Tiers into the early afternoon hours, with a possible
rumble of thunder east of I-81 in NEPA. A ridge of high pressure
over the north central US will amplify Monday morning,
generating a surface high over the Great Lakes. This will slide
eastward during the day Monday, bringing NW flow and dry air
into the region. Highs on Monday will be in the upper 60s to mid
70s.

High pressure overhead Monday night will bring, mostly clear to
partly cloudy skies and very light to calm winds. This will be a
nice setup for radiational cooling, dropping temperatures into
the low to mid 40s. Currently not seeing any frost for our
growing zones, but we will have to monitor this as we get
closer.

Tuesday will be a wonderfully pleasant spring day as the ridge
and accompanying surface high moves overhead, bringing dry
weather and mostly sunny skies. Winds shift to WSW during the
afternoon, allowing some warmer temps to push into the Twin
Tiers. Highs will reach the mid to upper 70s here, with low to
mid 70s to the north.

Tuesday night will not be as cool as the night before as SW
winds advect in a warm, moist airmass accompanied by increased
cloudiness. Temps will fall into the mid 50s for most, with
upper 50s in the Wyoming Valley and upper 40s in the Tug Hill
and Catskills.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
245 PM Update...

The nice, dry weather does not stick around for long as a
positively tilted upper level trough will sit over the eastern
US, pushing shortwave after shortwave through the region during
this period.

The first shortwave will push through Wednesday, bringing in a
warm front during the morning hours and scattered rain showers
to the region. Guidance is showing very low chances( <20%) of
CAPE reaching 500 j/kg across the Twin Tiers during the
afternoon. Rain showers will continue through the afternoon,
with a slight chance of an isolated thunderstorm over NEPA.

The upper level trough will drift eastward through the end of
the week, pushing multiple shortwaves and associated rain
showers through the area Thursday through Sunday. The upper
level trough will move overhead Friday, keeping temps cool for
the weekend as a Canadian airmass slides in from the north.
