CTP had good info in their discussion today.
.NEAR TERM /THROUGH TONIGHT/...
1045 AM/1445Z update:
Some adjustments to the forecast and HWO product, as per SPC
outlook for this aft. Main change was an increase in concern
for strong to severe winds with storms this afternoon across
north central PA. Showers and storms moving just north of east,
at about 35 knots, so not seeing a threat of flooding. Limiting
factor is dewpoints not expected to be all that high. Main
support is a rather strong upper level trough moving across the
region for the first day of August. Most of the activity will be
between 18 and 00Z.
Earlier discussion below.
715AM/1115Z: Near term fcst is in pretty good shape and
therefore no significant changes with the final midshift update.
Showers/storms will initially be focused over the far northwest
and southeast portions of the CWA through midday. Latest hires
data continues to suggest a line of convection capable of
producing strong to locally damaging winds will push southeast
across CPA between 18Z-24Z.
