While the bulk of Henri looks to miss us to the east, we do have the potential for daily thunderstorms in this tropical air mass, starting today..Where they pop up is anyone's guess lol

 

As the upper level system interacts with tropical system Henri, this
will bring progressively more moisture with precipitable water
values increasing to almost 2 inches. This combined with diurnal
instability will support generally scattered showers and
thunderstorms this afternoon and early evening. Moist airmass
supports the potential for locally heavy rainfall, with mesoscale
guidance suggesting the greatest risk for heavy rain across the
eastern Lake Ontario region. Otherwise, temperatures will remain
above normal with highs in the lower to mid 80s today.

Sunday night tropical system Henri will slowly meander its way
north-northwestward along the New York-southern New England border...
while becoming increasingly absorbed by the deep-layer closed low
over the mid-Atlantic states. On this track the heavy rains directly
associated with Henri will remain safely confined to our southeast...
though the larger-scale trough and tropical airmass across our region
will still lead to the potential for some scattered showers and
isolated thunderstorms across eastern/southeastern portions of the
area.

On Monday the closed low will open up a bit and slowly lift north-
northeastward across western New England. In doing so...this will
keep Henri and any of its direct impacts again confined well to our
east...though daytime heating of our warm and soupy airmass should
again lead to the development of some diurnally-driven showers and
thunderstorms across our area. The potential for these will be highest
across the North Country and interior portions of the Finger Lakes
where support from the larger-scale trough and diurnal instability
will respectively be the greatest...with chances notably lowering
with increasing westward extent across the balance of the area...
particularly across the Niagara Frontier where the bulk of the day
looks to be dry. At this point the bulk of the activity still looks
to be scattered in nature...though a brief period of more numerous
showers/storms cannot be ruled out across the North Country/interior
Finger Lakes. With the tropical airmass that will be in place...the
main issue with any slow-moving storms would be locally heavy rainfall.

Monday, showers and thunderstorms possible, with the greatest
potential expected across the eastern portions of the area. The
daytime heating and a tropical airmass will provide for at least the
chance of showers and storms. The track of Hurricane Henri will be
monitored closely as the western edge of the storm may approach the
North Country during the day on Monday, but most guidance doesn`t
push the system that far west. The plume of moisture associated with
the storm will push into the far eastern parts of the forecast area,
helping to fuel some of the showers and storms that are expected. If
Hurricane Henri does end up tracking east a bit quicker on Monday,
then that will be in response to the upper level trough moving east
more quickly as the storm gets phased into the upper level pattern.
This would result in lower chances for showers and storms on Monday
with the tropical moisture and upper level support tracking away
from the area.

Up to 82° here..

Sizzlecuse forecast 90° on Wed, so I lied when I said no more 90s haha

Yep...routinely hotter here than many places to the south in other states...it's absolutely absurd...regardless low elevation and city size. I saw upper 80s for Wednesday this upcoming week, and automatically knew that meant we'd be in the 90s for the 17th day this summer. lol

Snow Days Ahead

According to the Farmers’ Almanac’s time-tested weather formula, there will be snow, but probably not as much as a snow-sport enthusiasts might dream of. On average, we’ll see near-normal amounts of the white stuff from coast to coast. However, there will be notable month-to-month variations.

Winter’s chill will start gradually. In January, temperatures will start out mild for much of the country but will trend toward colder conditions during the middle to latter part of the month. But overall, the month will be stormy, especially along the Atlantic Seaboard where an active storm track will lead to a stretch of precipitation in various forms: rain, snow, sleet, and ice.

The Great Lakes, Midwest, and Ohio Valley will have more than their fair share of cold and flaky weather in January. The Northern Plains and Rockies will also experience Old Man Winter’s wrath with stormy weather culminating to a possible blizzard later in the month.

In sharp contrast, February will average out to be a much quieter month in terms of storminess across much of the nation. In the eastern-third of the country, for example, we calculate that on average there will be 57% fewer days of measurable precipitation compared to January, a significant drop-off. But that doesn’t necessarily mean that storminess will be completely absent.

We’re forecasting a “winter whopper” for parts of the Northeast and Ohio Valley toward the end of February. Another “atmospheric hemorrhage” from the Pacific could lash most of the far West, with everything from strong winds to heavy rains and snow.

March will see close to normal precipitation nationwide. But in a sense, March will be a microcosm of the entire winter. From start to finish, the month will be full of stretches of uneventful weather, but when it turns stormy, the precipitation will come in big doses. For the East and Midwest, for example, a late winter storm will blow in at mid-month followed by a nor’easter along the East Coast toward month’s end.

Can I trust a source that uses "flaky" to describe the weather? :lol:

I see our cool down for the end of the week is disappearing. "Sniff sniff" August is definitely going down as "hotter than average" this year. Lots and lots of 80s.

Especially considering that 80/60 are the average high/low for ROC. We're hitting mid-80s daily and around 70 at night. That's brining up the average quite a bit.

Yeah, the lows have been so high. Maybe I have a false memory of it...but I felt like stuffy, muggy nights were something I experienced on our vacations down south when I was a kid. Seems like the summers aren't much different up here than they are in the south. Just a blip...or a "new normal?"

i was going to mention that last week's projections of likely Below Normal for the 6-10 & 8-14 day periods in the NE seem to have gone into the crapper.  ;)  I realize they are only probabilities but looks like we've been granted a stay of execution.    Now let's get that Sizzle!

Yeah, these huge ridges are blasting in the heat. Tropical systems, like the ones we have been having, often seem to mess up the long-term prospects of cool downs.

It seems like it has either been raining or 85° and super humid.  Night time lows have been oddly high (and humid) as well.  This has turned out to be a remarkably moist summer.

I just hope we have a nice, long, dry, and warm fall... ;)

August temps have been well above normal for Buffalo & Watertown, both ranking in the top 5 for warmest August on record. Watertown is also well above normal for rain for the month making it the 4th wettest August on record. Rochester has been closer to normal for temps & rain.

Associated with this feature a surface low will cross northeast
across southeastern Canada. Meanwhile, its attendant cold front will
push across the lower Great Lakes Thursday before stalling across
the southern portions of New York Friday and Friday night.

Ahead of the aforementioned cold frontal passage Thursday, expect
showers and afternoon thunderstorms. While instability peaks with
MLCAPE values climbing to 3000 J/kg across North Central New York
mid/late afternoon Thursday, weak wind shear will hinder the threat
for severe thunderstorms. However, the weak wind profiles combined
with the increasing PWAT values (up near 1.5 to 2 inches) ahead of
the front will increase the threat potential for heavy rain. With
the passage of the front, activity will decrease late Thursday
evening through Thursday night. Highs Thursday will warm up into the
upper 80s across the lake plains with low to mid 80s throughout the
higher elevations across the Southern Tier and North Country.

As alluded to previously, the front will stall out across the
Southern Tier Friday. Behind the front, especially east of Lake
Ontario a much drier airmass will briefly reach the region dropping
dewpoints down nearly 10 degrees into the mid 50s Friday and Friday
night. Further south/southeastward a tad more humid airmass with
dewpoints in the 60s will reside promoting the chance for a few
afternoon thunderstorms Friday along the lake breeze boundaries.
Shower activity will then decrease Friday night due to the lack of
daytime heating. Otherwise, temperatures Friday will warm up into
the upper 60s to low 70s across the North Country and due to the
higher dewpoints across the remainder of the area, highs will range
in the mid to upper 70s with a few locations reaching 80.
