.SYNOPSIS...
* Mainly dry, seasonable weather pattern to continue across
  most of central PA through the second weekend of September
&&
.NEAR TERM /THROUGH TONIGHT/...
Frost advisory remains in effect until 8AM for the NW zones
where 3AM/07Z min temps are in the mid 30s. IR satellite shows
valley fog across north central PA which should continue to
expand/persist through sunrise before mixing out by 9-10AM.
Another pleasant day ahead with abundant sunshine, low humidity,
and light wind from the east. Highs in the low to mid 70s are
near to slightly below early September climo with the largest
departures from the historical average (3-6 degrees) across the
southern tier.
Hires models continue to indicate low clouds will invade eastern
PA tonight behind and increasing easterly low level wind flow.
It is plausible that spotty light rain reaches as far west as
the I81 corridor by 12Z Wed. We made minor upward adjustments
to sky cover with this fcst cycle, but if the trend continues
we would anticipate a mostly cloudy start to Wednesday with
perhaps some mentionable POPs and QPF
