6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen

area forecast discussion... Updated
national weather service pittsburgh pa
718 am edt Mon aug 19 2019
Warmth, humidity, and daily thunderstorm chances will continue
Near term until 6 pm this evening
715am update... Lowered pops given the lack of initiation point,
meaning storms will be more isolated in nature. Minor tweaks to temp
and sky grids today to account for latest sfc ob satellite trends,
but the overall forecast message remains in tact.
shortwave trough and surface boundary will move east of the region
this morning. Upper level flow behind the wave will return to zonal
with a bit of a curve toward the nw. Weak surface high pressure will
settle in over ohio this morning, and the atmosphere will dry out.
Even though we had fropa, it will do little to nothing to evacuate
the humid conditions. Because of this, the atmosphere will still
contain plenty of buoyancy. The good news is that the real unstable
air will establish itself south and west of the region. Additionally,
there is no real trigger to initiate convection today, absent
daytime heating. Storms will thus be more isolated in nature, relying
on colliding outflow boundaries for more scattered storm initiation.
As mentioned previously, it will remain warm and muggy today.
Short term 6 pm this evening through Wednesday
Zonal flow, north of a southern CONUS high, is expected to persist
across the region Tuesday. Shortwaves embedded in the flow should
maintain periodic shower and thunderstorm chances as warm and humid
A trough, and its associated cold front, are expected to track from|
the upper midwest to the upper oh valley great lakes regions by
Wednesday. Starting to see timing differences with this feature, so
pulled back on pops.
Long term Wednesday night through Sunday
Surface high pressure building under NE CONUS upper troughing should
return dry, cooler and less humid weather by Thursday and Friday.
Aviation 11z Monday through Friday
Patchy morning fog north of pittsburgh will quickly erode with
increasing sunshine mixing.
A moist and weakly unstable environment remains over the region to
fuel aftn eve showers tstms. However, warm air advection between
850mb and 700mb will cap initiation and make it difficult for storms
to form. Add in the lack of a strong frontal boundary or upper level
support, storms will be hard to develop today and any that do will be
isolated in nature.
The lack of moisture evacuation plus clearer skies and light winds
will allow for more efficient radiation cooling Tuesday morning,
creating patchy fog favoring river valleys.
With a number of disturbances passing through the region, periods of
flight restrictions due to tstms and patchy morning fog are likely

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
