.DISCUSSION...
As of 241 AM EDT Saturday...

KEY MESSAGE 1: A few showers and thunderstorms remain possible
this morning with some forcing along a frontal boundary dropping
out of Canada and as a wave moves west to east from the Lake
Ontario region. Forcing will not be overly strong with this
front, but some showers are already evident in northern New
York. These showers will move into north-central Vermont for the
morning before quickly dropping south.

Highest chances of showers and thunderstorms will be in
southern Vermont where a wave will move through late this
morning and early afternoon. This area is evident over western
Lake Ontario and will track eastward this morning. While strong
thunderstorms are not anticipated, lightning will be a threat to
those participating in outdoor Independence Day activities from
10 AM to 4 PM.

KEY MESSAGE 2: Wildfire smoke is evident over southern Canada
and is dropping southward with the front. As winds turn
northerly this area will advect over the region this morning and
persist until around midnight. Air quality is expected to drop
into the orange category becoming hazardous for groups that are
more sensitive to air quality degradation. Some lingering haze
is possible past midnight as high pressure moves in, but
conditions are anticipated to improve overall moving into
Sunday.

KEY MESSAGE 3: By the middle of next week, the warm weather
will continue to linger across the region. Current forecast
supports high temperatures in 80s to low 90s for next week,
although heat indices are not quite as high in comparison to the
recent heat wave. Overnight lows remain on the warmer side,
generally in the 60s, providing little relief from the daytime
warmth. Chances of showers and thunderstorms will be possible
throughout the week.
