.WHAT HAS CHANGED...
QPF has trended up quickly for the Friday rainfall with a more
convective element raising totals to between 0.25-0.75 inches
for much of the region. High temperatures rose some on Sunday,
given a later frontal passage and more pre-frontal heating
throughout the daylight hours Sunday.

.KEY MESSAGES...
1) Warming trend over the coming days before a Sunday night
cold front.

2) Very light rain today with additional waves of rain and
storms through the weekend.

.DISCUSSION...
KEY MESSAGE 1...

Subtle height rises across the region paired with over 3 days
of general WAA at 850 mb and a largely southerly surface flow
support high temperatures rising each day through the weekend.
High temperatures today will take a 10-15 degree leap over
yesterday and return us to above normal. 850 mb temperatures are
set to climb as high as 15C Sunday afternoon. This combined
with a breezy southwesterly flow ahead of the impending cold
front will allow high temperatures across much of the area to
punch into the 70s, with upper 60s north of I-80. Probabilities
for high temperatures over 75 degrees F are over 40% SW of
US-422 and rise to 70-80% south of I- 70. High temperatures on
Sunday could be as much as 20-25 degrees above average.

A cold front sweeps the region Sunday night, with cooler high
pressure filtering in behind it. High temperatures return to
near normal values but can fall on the order of 20-30 degrees
from Sunday to Monday.

KEY MESSAGE 2...

Mostly virga has been noted today with limited radar returns
being spurred by the movement of a weak short-wave through the
area. POPs begin to decline this afternoon and dry conditions
are expected overnight.

Another short-wave rounds through the largely west-
northwesterly upper-level flow Friday and pushes a surface low
across southern Ontario and into the Northeast. SFC heating
ahead of the front will supply weak instability on the order of
100-200 J/Kg, which could allow for some weak updrafts to supply
thunder chances but the likelihood of severe weather looks
quite low. With a more convective look to the precipitation (and
the availability of CAMs now) QPF expectations have risen to
between 0.25-0.75 inches, with the highest totals in heavier
showers and thunderstorms. Despite the uptick, little impact is
expected from this QPF.

An additional short-wave and associated surface front return
rain chances to the region Sunday-Sunday night. Ample heating in
moist southerly flow ahead of the front sets the stage for
storms once again and the machine learning models are projecting
some risk of severe weather. However, the overnight timing of
the front and a notable high bias early this season in the
machine learning models across our region bring some concern to
how real a threat this will be. At this time, SPC has no
outlooks for our region.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
VFR ceilings remain in place at 18Z, with some virga and light
rain showers crossing the region along with a weak shortwave.
Have PROB30 mentions for these showers to the southwest of PIT.
The shortwave departs by sunset, at which point southwest wind
around 10 knots will diminish. A VFR overnight period is
figured.

The next shortwave will begin to approach Friday afternoon, with
an increase in mid and upper clouds. Instability and moisture
availability will be better with this disturbance, with shower
potential introduced at FKL/DUJ (and at PIT after 20Z) by the
end of the TAF period. Any potential of thunderstorms should
hold off until after 18Z Friday. Better low-level mixing will
provide southwest wind gusts of around 20 knots by midday.

Outlook... Rain and thunderstorm potential, with attendant
restrictions, becomes higher Friday afternoon. A VFR Saturday
may then be followed by a frontal passage Sunday that could
bring another round of restrictions and a few thunderstorms.

.PBZ WATCHES/WARNINGS/ADVISORIES...
