A break we
had a break from the heat, but southern parts of our region will feel another
heat wave this week thanks to high pressure building to our west. Today will be
quite warm, but the humidity will be fairly low. That will change tomorrow with
hotter temperatures and a spike in humidity.
For today we
have a little trough over the region; this could spark a few isolated showers,
but most of us won’t see them. Those with the best chance at see any rain will
be across parts of Pennsylvania, into New Jersey, Maryland, and Delaware.
Tuesday is
going to be hazy, hot and humid with highs ranging from the low to upper 90s
across the region. With dewpoints in the 60’s into the low 70’s will make for heat
indexes in the 90’s into the low triple digits. For this reason, we have a Heat
Advisory for parts of our region.
Tomorrow we’re
going to have a weak cold front dropping in out of Canada, ahead of this there
will be showers and thunderstorms across northern New York State and northern
New England, some of these will be strong to severe, the best timing on these
thunderstorms will be late afternoon into the evening and maybe the overnight.
Right now, the Storm Prediction Center (SPC) has an Enhanced Risk for severe
weather closer to the Canadian Border, with a Slight Risk for severe weather across Northern
New York State and across Central Vermont, New Hampshire and Maine. The severe
risk drops the further south you go. These storms could have strong and gusty
winds. With gust of over 70mph possible, there will be the risk for moderate to
large hail and heavy downpours, a few isolated tornadoes are also possible. The
rain and storms should be confined to northern parts of the region.
The dome of
heat is going to try and expand farther east on Wednesday and Thursday. Hot air
out of the Canadian Plains will drop down and expand into southern parts of our
region. Northern New York State and northern New England will be north of a
frontal boundary, so they will be slightly cooler and less humid on Wednesday. But
the rest of the region will be baking. Again, air temperatures in the 90’s into
the low 100’s will make for high heat indexes. That cold front is going to try and drop south
Wednesday evening/night. This could set off a few showers and thunderstorms across
southern New York State, Pennsylvania, into the Middle Atlantic. Some of these storms could be strong to
severe. This will be the first in a series
of cold fronts that will be dropping into the region. The front is going to be very week, so it won’t
really impact air temperatures all that much for Thursday. But it will lower
the humidity slightly.

Friday is
when we will see the wave of cold fronts start to impact the region. These will
bring scattered rain showers and thunderstorms, some of these storms will be
strong to severe. With the chance for gusty winds, hail, frequent lightning and
heavy downpours. The cold front is going
to stall on Saturday, a few areas of low pressure move along it, these will be
capable of producing rain showers and thunderstorms across southern parts of
the region. The series of fronts are going to continue to drop into the region
over the weekend into early next week. These are going to cool the region down
quite a bit. On Monday, were going to see a couple of frontal boundaries set up
near the Gulf Coast. These could develop something tropical. Regardless of
development, we’re going to see tropical moisture surge northward
