Synopsis
A disturbance in the upper levels of the atmosphere will approach
and move across the region Sunday triggering scattered showers and
isolated thunderstorms mainly during the afternoon into the evening.

Another disturbance will cause scattered showers and isolated
thunderstorms again Monday mainly during the afternoon into the
evening.

Near term through today
Showers have moved off to our east or dissipated. Will have mainly
clear skies overnight with light winds. Temperatures will bottom
out near seasonable norms mainly in the 50s
a distinct short wave is moving across the great lakes region
and will track eastward through Sunday dampening across it
passes over region. As this disturbance approaches and crosses
the region with the heating of the day scattered showers and
isolated thunderstorms will occur across the area mainly during
the afternoon into the evening. Convective parameters are
expected to be rather meager with capes averaging 300-500 j kg
and showalter index values near 0c. Wet-bulb zero heights are
lowering and will be less than 10k feet, so would not be
surprised to see some small hail with the deeper convective
elements along with some strong wind gusts.

Short term tonight through Monday night
Convection should diminish with the loss of daytime heating
Sunday evening with a party cloudy to mostly clear skies. Short
wave quickly transverses across the st lawrence valley through
the evening hours leaving behind small height rises overnight
which will extend through Monday morning.

The next short wave, currently near lake winnipeg, will begin
to sharpen the trough Monday into Monday night. Again scattered
convection is expected to develop with help of instability from
diurnal heating as lapse rates increase between 6.5-7c km.

However, greater coverage is expected as height falls will
be more dramatic to maintain threat for convection into Monday
night. The chances for thunderstorms should be be tied to
daytime heating once again. With more cloud cover expected
Monday temperatures will be cooler with highs in the mid 60s to
upper 70s.

Long term Tuesday through Saturday
A trough from the great lakes swings into the northeast Tuesday with
models showing signs of it becoming negatively as it moves across
the eastern half of the region. The thermal profile will actually be
fairly cool for late june with h850 isotherms ranging 6-8c leaving
us with high temperatures below normal in the low 70s and upper 60s.

The trough's dynamics are notable and its associated cool pool aloft
should aide in diurnally driven convection. However, 700mb moisture
is lackluster so convection should be isolated to scattered with the
highest pops placed in the northern cwa.

Temperatures stay cool heading into Tuesday night with lows falling
into the 40s and 50s. An additional shortwave trough (albeit weaker)
may lag behind so have left slight chance pops for northern areas
Tuesday night. High pressure shifts into the mid - atlantic with its
northern periphery moving into our region Wednesday. Unfortunately,
the ridging and dry period is brief as another disturbance from the
northern great lakes southern canada moves into eastward. Its
associated warm front looks to nose into ny western new england
Thursday but timing is still uncertain. However, the euro and
canadian are fairly in line showing the precipitation arriving
during the second half of the day while the GFS the outlier arriving
much quicker. Considering this is day 6, left a broad brush of
chance pops for the cwa. While the guidance yesterday suggested the
warm front may get hung up somewhere in the adirondacks vt area, the
atmospheric flow upstream is fairly quick and thus should allow the
front to progress through the region.

By Friday we are in the warm sector as southwesterly flow around the
bermuda high advects warm and humid air back into our region. With
additional shortwaves riding within this warm humid southwesterly
flow, have kept chance pops for Friday as well. The system's cold
front may move into the area Saturday potentially bringing some
relief but again exact timing is uncertain.

Aviation 06z Sunday through Thursday
Mainly clear skies overnight aside from some patches of mid high
clouds. Have kept mention of bcfg at kpsf kgfl tonight with
clear skies and light winds. Have also included bcfg for kpou
since their dewpoint depression is only 3f after earlier light
rainfall. Could see a vis restriction there before the night is
through, but confidence not high enough to include in the tafs
attm.

During the late morning to afternoon hours, a good cu-up is
expected thanks to cold midlevel air and a vigorous midlevel
disturbance rotating into the area. Cloud bases are expected to
be up around 5-6kft. Isolated to scattered showers and perhaps a
thunderstorm or two are expected to develop. Kept mention of
vcsh from 17-23z at all sites except kpou. Clouds and showers expected
to decrease after diurnal heating wanes in the evening.

Light winds for the remainder of the overnight hours will become
generally southwest to west at around 10 to 15 kt by the
afternoon, with gusts to around 20 kt possible. Winds will
diminish during the evening.

Outlook...

Sunday night: low operational impact. Slight chance of shra.

Monday: moderate operational impact. Chance of shra... Tsra.

Monday night: moderate operational impact. Chance of shra... Tsra.

Tuesday: moderate operational impact. Chance of shra... Tsra.

Tuesday night: no operational impact. No sig wx.

Wednesday: no operational impact. No sig wx.

Wednesday night: no operational impact. No sig wx.

Thursday: moderate operational impact. Chance of shra... Tsra.

Fire weather
Winds will diminish this evening. Winds will be westerly again
Sunday but not as strong at around 10 mph with gusts into the
teens. Isolated to scattered showers and perhaps a few
thunderstorms are expected Sunday afternoon as another cold
front approaches. Minimum relative humidity values of 45 to 55
percent are expected Sunday afternoon.

Hydrology
Hydrological problems are not anticipated through over the next
several days. A drier, more comfortable airmass continues to
settle into the region. Isolated to scattered showers and
perhaps a few thunderstorms are expected Sunday afternoon as
another cold front approaches. The weather will remain unsettled
early next week as another low pressure system approaches and
moves across the region with chances for convection Monday
afternoon into Tuesday.

and forecast river stages and lake elevations, please visit the
advanced hydrologic prediction service AHPS graphs on our
website.

Equipment
Kgfl airport observations are coming in and we will continue to
monitor this trend.
