area forecast discussion

724 am edt Thu mar 30 2017

Synopsis
We will start off dry today, though clouds will increase and
thicken in the afternoon. Our next system will spread rain
across the area late today, which will linger through Saturday.

For some areas east of interstate 81, there will be a wintry
mix of snow sleet and freezing rain at times. Some snow or ice
accumulations will be possible at higher elevations from tug
hill and catskills to poconos.

Near term /through Friday/
415 am update...

dry for now, but a cold rain will overspread the region late
today through Friday. Main concern will be potential for wintry
mix at higher elevations east of i-81 tonight into Friday. Also,
with between an inch and inch- and-a-half of total
precipitation with this system late today through early
Saturday, river rises are expected. Please see hydrology section
near the bottom of this discussion for more details on flood
potential.

Dry ridge of high pressure is sitting on this morning but it
will shunt eastward this afternoon. Early sunshine will give way
to thickening clouds as next system approaches and moistening
warm air advection occurs aloft. What is effectively an elevated
warm front will lift through this afternoon and evening,
resulting in increasing chances for rain especially from central
twin tiers through finger lakes and eventually syracuse-mohawk
valley. However, at the surface, chilly low level air will keep
feeding in from the east-southeast courtesy of stout pressure
gradient between surface low making its way from the midwest,
and high pressure in quebec with ridge extending through new
england. This is why there is the wintry mix concern east of
i-81 later tonight into Friday morning.

There is a lot of uncertainty in thermal profiles and thus
precipitation types and amounts. We will probably need a winter
weather advisory for a portion of our area east of i-81 but in
coordination with NWS buffalo/albany/upton/mount holly, we will
allow forecasters another look at latest models later today to
get details finessed before deciding exactly which counties.

The NAM model has performed quite well this winter during mixed
precipitation events due to its handling of terrain features
and thermal profiles. I thus leaned hard on NAM for this
forecast at least for precipitation type whereas I used a blend
of models for precipitation amounts. Overall trend has been for
less snow/sleet and more of a freezing rain concern for higher
elevations of catskills and, at least for a time, the poconos.

Meanwhile, towards higher elevations of oneida county and
especially tug hill plateau area, cold air appears thick enough
for initial rain to change to a quick 1-3 inches or so of wet
snow-sleet tonight before a smaller window of freezing rain
early Friday. By Friday afternoon, only the highest elevations
of the catskills should still have a freezing rain threat,
though coverage could increase again Friday night as mentioned
below in the short term discussion.

Short term /Friday night through Sunday night/
A low pressure storm system will slide off the new jersey coast
Friday night, slowly bringing an end to showery mixed
precipitation. Friday night however, a changeable mix of rain,
snow, sleet, and possibly freezing rain is forecast over much of
the eastern forecast area.

Cold surface temperatures Saturday morning will keep the threat
for mixed precipitation over our extreme eastern counties. By
early afternoon, temperatures will be warm enough to change any
remaining shower activity over to rain.

High pressure will bring a sunny day Sunday, with temperatures
back in the 50s.

Long term /Monday through Wednesday/
An unsettled long term is forecast again, as another wave ejects
out of the central plains and into the ohio valley late Monday
or early Tuesday. The surface cyclone will meander toward the
mid-atlantic coast Tuesday afternoon, with rain or rain showers
spreading north into ny/pa through early Wednesday.

Maximum temperatures will average in the upper-40s to middle-
50s.

Aviation /12z Thursday through Monday/
Vfr conditions today, however, our next system will begin to
bring restrictions this evening and especially later tonight.

Initially mainly clear sky will give way to increasing high thin
clouds around or above 20 kft agl starting around midday, which
will then thicken and lower with time late afternoon through
evening. Rain will be spotty and light at first but from about
00z west to 06z east will bring in MVFR restrictions with fuel
alternate required to ifr conditions not far behind. Initially
light and variable winds becoming southeast 6-12 knots for
kith-kbgm-kelm-kavp; maintaining east-southeast ksyr-krme
outlook...

Friday through Saturday... Restrictions likely in
showers, especially Friday through Friday night. Snow or sleet
may be mixed in at times for krme.

Saturday night through Monday... PrimarilyVFR.

Monday night... Good chance of rain and associated restrictions.

Hydrology
350 pm edt Wednesday update...

a renewed threat for minor flooding returns this weekend as low
pressure moves from the southern plains to the eastern
seaboard. The system currently appears strong enough to generate
widespread QPF in excess of one inch by Saturday morning. The
main problem with this situation is the forecast of marginal
boundary layer temperatures. We should see a portion of the
precipitation fall as snow, sleet or freezing rain at the onset,
followed by several hours of rain, then a wintry mix again at
the conclusion of the event. This definitely hampers the
prediction of runoff and accurate flow/stage forecasts.

The current best estimate suggests that temperatures will be
marginally cold, and although we may see differing precipitation
types, not a lot of this new precipitation will be locked up.

Another factor contributing to the confusion is how the remaining
snow cover deep in the woods and hills of the susquehanna and
upper delaware headwaters will behave. Colder than usual temperatures
in the 30s to low 40s may not do much to melt the snow, however,
fairly warm rain falling into the ripe snow pack could do some
damage and exacerbate additional runoff.

Bottom line is that river rises will kick in again, and the
most plausible river simulations do suggest parts of the
susquehanna and delaware rivers could exceed their posted minor
flood stages by a little bit. Current confidence is very low,
and our best river forecasts are probably not going to happen
until the precipitation is on the ground. Thursday we will
evaluate the need for another flood watch.
