Area Forecast Discussion

245 PM EST Wed Jan 3 2024
.SYNOPSIS...
Snow showers return tonight with another shot of cold air on
Thursday. Still lots of uncertainty regarding impacts from low
pressure moving up the northeast coast this weekend.
&&
.NEAR TERM /THROUGH THURSDAY/...
KEY MESSAGES:
-Scattered snow showers return late Wednesday night through
Thursday morning
-Minor accumulation in the lowlands with up to an inch possible
in the higher elevations
-Turning dry again Thursday afternoon and colder with a brisk
northwest wind
-----------------------------------------------------------------
Dry conditions will continue through the afternoon with zonal
flow aloft and high pressure at the surface. Cold advection
this afternoon with a weak shortwave trough crossing the PA/NY
border is resulting in a stratocu deck north of PGH while areas
to the south get a quick dose of sunshine.
Snow showers return to the region tonight as a relatively quick
moving front drops south across the region.
With minimal moisture to work with and the boundary layer
failing to extend into the DGZ, snow accumulations will be
minimal. Additionally, behind the front the level beneath the
cloud deck dries out quickly and the wind direction is too
northerly for much in the way of lake effect or orographic snow
showers.
Outside of the ridges, and possibly some locations in the I-80
corridor, the latest NBM range of potential snowfall (10th
pct-90th pct)for Thursday is well below an inch. Even in the
higher elevations the 90th percentile sits at 1 inch.
Probabilities for even 0.01-0.05 inches remain low.
Strong cold advection behind the front will maintain cloud
coverage and keep the diurnal range in temperatures to a
minimum.

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
KEY MESSAGES:
-Sunshine returns on Friday.
- A weather system could bring impacts to the area over the
weekend, however, there remains too much uncertainty to
pinpoint any details this far in advance.
NWS Pittsburgh just being lazy in their discussion whatever it may be.
