BANGHOFF/DANGELO

What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS State College, PA wrote its last area forecast discussion before this river flood warning went out at Aug 14, 7:55 AM EDT, 1 hour 52 minutes earlier.

Area forecast discussion, Aug 14, 7:55 AM EDT, 1 hour 52 minutes before
Area Forecast Discussion
National Weather Service State College PA
755 AM EDT Tue Aug 14 2018

.SYNOPSIS...
A slow moving upper level low pressure system located over
Central Pennsylvania this morning will drift northeastward
to near Boston by daybreak Wednesday. This weather feature
will bring fairly numerous moderate, to occasionally heavy
showers and isolated thunderstorms across Pennsylvania today
through early tonight. Localized Flash Flooding is possible
where heavy showers and thunderstorms train, or remain
stationary over the same locations. A ridge of high
pressure will move east from the Ohio valley and crest over
the region Wednesday into Thursday morning, accompanied by
dry weather, light wind, and temperatures about 5 degrees above
normal both Wednesday and Thursday. A weak cold front will
arrive late in the week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Flooding concerns re-igniting across portions of the Central
and North- central Mtns of PA early today as a compact, though
rather potent spoke of mid/upper level vorticity pivots west and
SW around the center of a slow-moving upper low located across
the Mid/Lower Susq Valley.

GOES East, Mid and Upper level water vapor channels show some
drying aloft and subsequent cloud-top cooling with occasional
IC flashes and CGs near and to the SW of KUNV over the past
hour.

QPE to FFG has increased to 70-80 percent in a few of the
heavier slow-moving showers/TSRA between KUNV and KJST, with
Hydrophobic Unit Streamflow values also expanding/increasing to
between 3.5-7.5 M3*Sec-1*KM-2. These values are sufficient to
begin poor drainage flooding and bankfull conditions on small
streams in that area, and prompted the expansion of the Flash
Flood Watch that runs through 02Z Wed.

Last several runs of the HRRR have been erratic, with runs from
around 04Z showing a concentration of convection and 2+ inch
rainfall between KIPT and KSEG, while the last few runs of this
CAMS guidance quickly dissolve the current and most intense
convection near and to the south of KUNV and shift the
concentration to the Mid Susq Valley and points north where WPC
has its highest risk of Excessive Rain this morning.

Compact area of convection is intensifying between KSEG and
KAVP and this is where the earlier runs of the HRRR showed the
highest QPF. Another area to monitor closely over the next
several hours.

Expect the current and aforementioned compact vort lobe to
maintain better areal coverage and intensity of the convection
over Central and Scent PA than the HRRR depicts, before the
brunt of the showers/isolated TSRA shift primarily to the north
and east of a KBFD to KUNV to KSEG line this afternoon and
evening as the upper low lifts across NEPA.

Although the flash flood threat is not as great as Monday,
very wet ground could leave the eastern counties susceptible to
additional flooding issues through this afternoon/early
evening.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
Upper low continues to slowly lift newd to the Hudson Valley
later tonight. This will lead to steadily decreasing areal
coverage and intensity of showers as the HREF shows very little
QPF to the West of a KELM to KSEG line and PWAT values on the
GEFS drop from about 40MM at 00Z Wed to under 25 MM by 12 WED
across most of the CWA.

Any partial clearing will combine with the moist ground and near
calm air to produce areas of dense valley fog late
tonight/early Wed morning. Min temps will still be near to
slightly above normal for tonight - in the upper 50s NW to low
and mid 60s elsewhere.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Models agree in the current upper low lifting out across the NEw
England states and weakening Wednesday, bringing a short period
of dry weather for a change for midweek as a flattening ridge
aloft slides east across PA.

The respite in the rain will be short lived as a new upper
trough/weak cold front is slated to approach the area Thursday
and Friday. In fact the models have a pair of upper shortwaves
that translate into several more days of at least scattered
showers and thunderstorms, mainly from later Thursday through
Saturday.

Drier weather should arrive for Sunday, but the overall pattern
looks to remain unsettled as the medium range guidance favors
and eastern trough and western ridge pattern through at least
the middle of next week.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
Upper low continues to bring impacts to flying conditions over
central PA. Conditions variable this morning, with restrictions
generally confined to the NW half. But showers/isolated
thunderstorms bringing local reductions and brief heavy rainfall
as they drift southward.

Convection should retreat to just the NE counties by late
morning as conditions gradually improve to VFR, but scattered
showers/tstms return this afternoon with local impacts.

Break in the precip starts tonight but anticipate ceiling
restrictions to develop over the western higher terrain and
(with very wet ground) a good amount of valley fog areawide.

.Outlook...

Wed...AM fog. Otherwise no six wx.

Thu-Sat...AM fog. Otherwise, scattered showers/tstms will bring
local restrictions.
