area forecast discussion
national weather service pittsburgh pa
158 pm edt Sun mar 26 2017

Synopsis
Warm temperatures will be marred by rain this afternoon and
Tuesday as a series of low pressure areas cross the region. A
Tuesday cold front will drop readings back toward the averages.

Near term /through tonight/
With noon update, tweaked pops for rain moving into eastern
ohio, as well as rain across central west virginia that will
move northeast into the region. Also tweaked temperatures a bit
in locations that received a few hours of Sun earlier. General
trend of forecast appears to be on track. Previous discussion
follows.

The primary change with the 8:30am forecast update was to slow
down arrival of precipitation by a couple of hours in most
locations. Closest precipitation remains west of the columbus
metro area, and trended the forecast in the direction of the
hrrr/rap. Only minimal changes made to the rest of the forecast.

Shortwave ridging in advance of midwestern low pressure continues
to suppress precip over the upper ohio region despite the presence
of a stalled front analyzed across the pittsburgh area.

That situation will change today as the low is forecast to continue
digging eastward, escalating pops from the west as the system
trundles toward the lakes. A general half, to three quarters of
an inch of rainfall is expected with the passage, and in the
wake of the systems occluded front during the next 24 hours.

Thunderstorm formation is progged to be hampered by meager
instability, although deep layer shear will be favorable for
severe as usual this time of year with the crossing low. A
chance thunder mention was maintained with the categorical rain
pop.

Rain chances will fade quickly on Monday morning as the weakening
trough slides eastward. Given the occluded nature of the front,
warm temperatures will be maintained in its wake.

Short term /Monday through Tuesday/
Shortwave ridging is timed to keep much of Monday dry, but
another midwestern trough, albeit weaker is likely to generate
more precip on Monday night and Tuesday. That system is
projected to pull a cold front across the region later on
Tuesday which will drop temperatures closer to the seasonal
averages.

Long term /Tuesday night through Sunday/
With high pressure settling in behind Tuesday's cold front and
northerly flow developing, dry and seasonable weather is
expected Tuesday night through Thursday. By Thursday evening,
the GFS and ECMWF begin to show diverging forecasts, with one
model showing low pressure over lake huron by Saturday morning
and the other model showing low pressure across tennessee. Have
stuck close to the superblend through this part of the forecast.

Aviation /18z Sunday through Friday/
Low pressure tracking across the oh valley/lower great lakes
will result in 3 distinct periods of showers the remainder of
the afternoon and tonight.VFR looks more likely to be
maintained after the first wave... But as moisture increases in
the lower levels deterioration to low MVFR is likely.

Thunderstorms still remain a possibility, however, have not been
included in tafs at this time based on limited instability.

Outlook...

restrictions are likely again Mon night/tue with a crossing
cold front.

Pbz watches/warnings/advisories
Md... None.

Oh... None.

Pa... None.

Wv... None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
