.SYNOPSIS...

and Tuesday night. Another cold front will cross the region
Thursday.

.NEAR TERM /THROUGH SUNDAY/...
903PM Update...Radar scans show rain showers moving out of the
region faster than previously forecast. Adjusted to show this.
Otherwise, the rest of the forecast looks good.

Previous Discussion...
Weak low pressure moving east tonight will result in showers
and isolated thunderstorms this evening. The low will weaken as
it pushes east later tonight wih showers and isolated
thunderstorms diminishing after midnight. Patchy fog is also
expected. Lows tonight will mainly be in the low to mid 50s
across the region. West to northwest flow aloft is expected
during Sunday. Mainly cloudy skies can be expected Sunday with
just some widely scattered showers expected as a weak
disturbance crosses the region. Afternoon highs will be warmer
on Sunday. Highs will range from the upper 60s to lower 70s.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
Sunday night into Monday, ridging aloft will move overhead,
along with warmer temperatures in the mid-levels. Deterministic
model runs indicate temps near 20 - 22C at 850hPa, so think
temps will be slightly higher than current deterministic run
of the NBM is showing. Not sure dewpoints will rise enough to
worry about heat headlines; right now it just looks like a muggy
day with highs in the mid to upper 80s. On Tuesday another cold
front will approach from the west, bringing clouds early on
which will help keep high temps slightly lower. Some potential
for thunderstorms ahead of the front, however right now CAPEs
are very low, even in the CAMs. Plenty of shear and high
PWATs around 1.8 to 1.9", so cannot rule out heavy precip and
maybe some gusty winds withe precip loaded thunderstorms but
overall the severe potential does not look high at the moment.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
The precip will pass through on Tuesday night, clearing for
Weds, but the cooler air will not arrive until Thursday. This
generates an opportunity for some air-mass thunderstorms across
the north on Wednesday night. On Thursday, cooler air will
begin to move in, and by Friday high temps will be much more
seasonable. Timing of the upper level trough crossing the area
is variable at the moment, so weather for Friday and Saturday
still remains uncertain with somewhat low confidence in the
forecast.
