Area Forecast Discussion
National Weather Service State College PA
147 PM EDT Fri Aug 29 2025

.SYNOPSIS...
* Chilly fall-like pattern with low humidity continues today
  through Sunday.
* Meteorological Fall (September 1) kicks off with continued
  pleasant and dry conditions and a gradual warmup for Monday
  through Wednesday.
* Cooler than normal temperatures will likely be observed across
  most of the area today into tonight.

&&

.NEAR TERM /THROUGH TONIGHT/...
Consistent northwesterly flow today is keeping our high temps 5
to 10 degrees F below normal for this time of year across the
central mountains and up through northwestern Pennsylvania. Fair
weather cu will continue to spread across the area this
afternoon making for a pleasant end to the work week. High
pressure will build into the south east portions of the state
late tonight and should become centered over Central PA
Saturday.

Clouds will clear overnight and winds will become calm, making
ideal conditions for efficient radiational cooling and lows well
into the lower 40s across much of the CWA. Across the northwest
mountains near Bradford temperatures could dip into the upper
30s with some spots possibly developing localized frost in the
coldest places.

&&

.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
Saturday will feature a prolonged return to mostly sunny skies,
low daytime humidity with excellent vsby and high temps in the
upper 60s to mid 70s from the northern and western high terrain,
to the Valleys of Scent and SE PA. Strong high pressure will
firmly be in place by Saturday afternoon. The center of the high
will be located over the southern Great Lakes region. The fall
like conditions will be here to stick around for the end of
August.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
High pressure from north-central Canada will keep it (very) dry
for the second half of the weekend. The compact upper low just
to our NE will finally lift away before the start of the work
week, but troughiness remains. The sfc high should fend off
rainfall until the second half of the upcoming week. However,
low level southeast flow could make for some pesky low clouds
at times. Temps rise only slightly for the first half of the
week (maxes in the 70s and lower 80s). The next chance for rain
will not arrive until late Wednesday into Thursday as the next
spoke of the upper level trough swings down from central Canada
to bring another cold frontal passage to the Mid-Atlantic and
New England regions.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Widespread VFR conds were found across Central PA early this
afternoon, beneath partly sunny skies with a northwesterly sfc
breeze occasionally gusting 15-20 kts.

Winds will diminish this evening. Some model guidance is
suggesting that there could be fog and/or low clouds across the
NW mtns overnight. However, confidence is low enough that
decided to leave it out of the TAFs for now. Otherwise, expect
continued VFR conds.

Regardless, Saturday should feature plentiful sunshine and
widespread VFR conds areawide.

Outlook...

Sat-Tue...AM valley fog possible; otherwise predominantly VFR.

&&

.CLIMATE...
Altoona set a record low temperature yesterday (8/27) of 43
degrees (45 in 1958).

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
