...AIR QUALITY ALERT IN EFFECT UNTIL 11 PM THIS EVENING...
.DISCUSSION...
An Air Quality Alert is in effect until 11 PM this evening at the
request of the Massachusetts Dept of Environmental Protection for
fine particulates. Smoke from wildfires in central Canada have
spread across a large portion of New England and has led to
reduced air quality. Individuals with asthma, lung or heart
disease should limit prolonged outdoor activity given these
conditions.
Hazy, smoky conditions are expected to continue through the rest
of the afternoon. Some improvement in visibilities are expected
tonight as the most concentrated area of smoke moves westward into
interior Southern New England. Aside from the hazy, smoky
conditions, dry weather is expected to go along with seasonable
temperatures in the low 80s and low humidities as well.
Cloud cover increases for the second half of the overnight with
low temperatures in the upper 50s.
Overcast conditions are expected for Sunday, with the best chances
for rains from mid-morning to the early afternoon. An isolated
thunderstorm is possible with this shower activity but widespread
or strong thunderstorms are not expected. High temperatures in the
upper 70s.
