Can I see my 3rd consecutive sub 70° Max in a row? Guess I'll have to wait and see lol

Forecast high was 72°, so far we have maxed out at 68.5° but has since dropped a couple degrees.. Obviously still plenty of time to warm...Another picture perfect day..

Fairly complicated scenario setting up for the first part of the new
work week with potential for some beneficial rains, but also the
possibility for some stronger storms. One thing that looks more
certain at this time is that any remnants/associated moisture from a
tropical system moving northeast from the Gulf Coast should remain
south of the area.

A large upper trough will dig across the upper Midwest/upper Great
Lakes on Monday, while strengthening main surface low pressure
pivots northeast into James Bay. A strong trailing cold front will
approach from the west on Monday. Deep southwesterly flow ahead of
the aforementioned features will pump GOMEX moisture northeast
across the area. This combined with very warm/humid airmass and
fairly strong mid/upper level dynamics in place should lead to the
likelihood for showers and thunderstorms to break out across the
area by Monday afternoon, some of which could be on the stronger
side. High PWATS will mean the potential for locally heavy rainfall
as well. At the same time, upper jet will be strengthening over the
upper Great Lakes aiding in the development of low pressure on the
cold front under the right entrance region of the upper jet. This
will likely slow the eastward progression of the surface boundary,
allowing for the potential for showers and storms to linger into
Monday night. At this point appears cold front will slowly cross the
area sometime later Monday night into Tuesday as surface low
pressure rides northeast along the boundary. Combined with plentiful
moisture still in place and right entrance region of the upper jet
overhead, this would continue to support the likelihood of showers
right into the day on Tuesday, with lessening chances for thunder as
the day progresses owed to instability getting shoved east of the
area with the boundary.

Main upper trough axis crosses the area Tuesday night with the
chance for a few lingering showers. A much cooler and drier airmass
is then set to move into our area for Wednesday and Thursday as high
pressure builds across the area from the west. Upper troughing will
remain overhead which will keep the cooler air locked in over the
Northeast and Mid Atlantic. Despite any diurnal instability that
develops with the cool airmass overhead, limited moisture will
preclude much in the way of any shower development either day, with
much of the time remaining dry.

Otherwise, above normal temperatures and high humidity levels on
Monday will trend downward, with below average temperatures by
Wednesday and Thursday and much more comfortable humidity levels.

Satellite imagery showing an expansive area of convective debris
clouds moving into Western NY. Clouds will continue to increase from
west to east through midday. While the thickening debris clouds will
yield some showers...dry air blow H7 will retard the advance and
amount of pcpn. Meanwhile...the threat for thunderstorms has mainly
shifted to the later parts of the afternoon and evening.

A complex convective forecast will evolve through tonight, with the
timing and placement of better chances of showers and thunderstorms
tied to subtle convectively manipulated shortwaves and vorticity
maxima. Synoptically, a mid level trough will move from northwest
Ontario today to western Quebec by late tonight, with an associated
upper level jet streak moving from the central Great Lakes today to
the Ottawa Valley by tonight. A series of more subtle and
convectively augmented shortwaves downstream of the synoptic trough
will move east across the Ohio Valley and eastern Great Lakes within
a plume of deep moisture, with PWAT exceeding 1.5" later today
through tonight.

Following the first round of rain chances, there should be a break
for several hours this afternoon across Western NY, and late
afternoon/early evening east of Lake Ontario. The clouds and showers
moving through during the day will interfere with destabilization,
only allowing for relatively modest instability to develop. Another
subtle mid level trough will reach the eastern Great Lakes during
the evening, supporting another round of showers and scattered
thunderstorms. The chances for thunder should be higher with this
second batch, with a more favorable thermodynamic environment in
place. The showers and scattered storms will move east overnight,
with rain chances gradually diminishing from west to east as the
trough axis moves into eastern NY.

The highest severe weather chances today and tonight will be found
southwest of our region across the Ohio Valley, where the eastern
extent of an Elevated Mixed Layer (EML) plume will contribute to
strong destabilization to the south of a composite outflow boundary
from the morning convection. Lack of instability will be the main
limiting factor across Western and Central NY. If enough instability
develops, moderate effective shear may result in a few storms with
strong wind gusts during the evening across Western NY, but this
risk appears low at this time. Heavy downpours will occur with any
storms that develop as PWAT values exceed 1.5

Heading to Wyoming and Colorado tomorrow  for 10 days. Quite the forecast where I may be able to see snow and 100 degree temps all in the same week. Planning on going up into the snowy mountains of Wyoming on Monday where high temps look to be around 50 with snow showers in the morning with temps in the 30s. Then have a wedding in Denver on Thursday where the high is 99 degrees. Should be a fun time with lots of weather extremes.

Gotta be some gorilla hail in that thing.  Never see such big pink blobs like that on the NWS radar.

At 847 PM EDT, a severe thunderstorm was located near Wilmington,
moving southeast at 15 mph.

HAZARD...Two inch hail and 70 mph wind gusts.

SOURCE...Radar indicated.

IMPACT...People and animals outdoors will be injured. Expect hail
         damage to roofs, siding, windows, and vehicles. Expect
         considerable tree damage. Wind damage is also likely to
         mobile homes, roofs, and outbuildings.
