a cold front moves through the area.

.DISCUSSION...
KEY MESSAGE 1)
Clouds will clear early this morning followed by scattered to broken
diurnal cumulus. Finally a dry day as high pressure builds in.

As a long wave trough slowly moves across eastern Canada, a series of
short waves will move through the base of the long wave and pass
across the region Wednesday into Thursday. At the same time, an
east-west oriented cold front will sag through the forecast area
Wednesday night. This will all come together to bring more showers
and thunderstorms Wednesday afternoon and night. And some post-
frontal showers will still occur on Thursday. Precipitable water is
forecast to increase to around 1.7 to 1.8 in and warm cloud depth
does eventually increase to around 4 km. These more favorable
parameters will be rather transient, so cannot rule out some locally
heavier rain in any storms, but that should not be focused on any one
area or be persistent.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
VFR will continue at the terminals. Lingering clouds will diminish
early in the period. Scattered to broken cumulus will develop with
heating and then diminish towards 00Z. Any ceiling will be above
3kft. Mid clouds will start to spread in during the latter part of
the period. If cloud deck is not too extensive, then shallow fog may
reduce visibility at KLUK.

OUTLOOK...Thunderstorms possible Wednesday into Wednesday night and
then again Saturday afternoon. MVFR to IFR ceilings and visibilities
possible Wednesday night into Thursday.
