Area Forecast Discussion
National Weather Service Burlington VT
320 AM EDT Mon Jul 30 2018
.SYNOPSIS...
Surface high pressure over the region this morning will provide dry
and seasonal weather to the North Country through tonight. Warm and
more humid conditions return Tuesday with chances for showers and
thunderstorms Tuesday afternoon through the remainder of the work
week, especially Wednesday and Wednesday night, as high pressure off
the Atlantic coast maintains a warm moist southwest flow into our
area.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 319 AM EDT Monday...A welcomed break from active and
humid weather is the forecast for today as surface high pressure
centered just south of the area will provide fair and dry
conditions through tonight. After early morning burns off high
clouds will increase from southwest to northeast and some fair
weather cumulus will develop this afternoon, but no
precipitation is expected. 925mb temps rise slightly from
yesterday to around +20C supporting highs mainly in the upper
70s to low 80s, with comfortable humidity as dewpoints will fall
into the low/mid 50s this afternoon.
Clouds continue to increase going into tonight associated with the
return of moist southwest flow between an approaching upper trough
and the Bermuda high parked off the Atlantic coast. Thinking clouds
will inhibit any fog development despite light boundary layer flow
with lows a few degrees milder than the previous night in the 50s to
low 60s. For Tuesday, have backed off PoPs quite a bit from the
previous forecast based on model trends. Mid-level heights are still
rising across most of the area through the day, and latest trends
are for the arrival of higher PWATs to be delayed until Tuesday
night or Wednesday. In addition, little instability is present along
with limited forcing, all pointing to less chances for
precipitation. That said, across northwest New York closer to the
approaching upper trough I could see a few showers developing so
will maintain some low chance PoPs there, but from the Champlain
Valley eastward think it will be a dry day. 925mb temps don't change
much from the previous day so highs will once again be in the upper
70s to low 80s, but humidity will begin to increase as dewpoints
climb into the low/mid 60s.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/...
As of 307 AM EDT Monday...Mainly a persistence forecast through
Tuesday night and Wednesday with one notable adjustment, namely
to lower pops downward quite a bit Tuesday night. Latest model
trends suggest that despite increasingly moist southerly return
flow, the overall lack of dynamic forcing should allow any
scattered afternoon convection on Tuesday to generally wane
overnight with loss of insolation. As such I've carried only
token 20/30 pops overnight, focused mainly across the south and
west in closer proximity to deeper moisture plume. Low
temperatures to range through the 60s to locally near 70 at
KBTV. By Wednesday that plume rides northeast into our region.
This, along with noticeable, albeit weak diffluence aloft in
advance of a dampening shortwave trough to our west should be
sufficient to drive scattered to numerous showers and storms
across the region. PWATS in the 1.7 to 2.0 inch range should
ensure locally heavy downpours in more robust cells. At least
some modestly robust instability and deep layer shear will also
be present so a few cells may also trend on the stronger side.
Time will tell. It will definitely feel more summery as
dewpoints climb well into the 60s to around 70 and daytime highs
top out in the upper 70s to mid 80s.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 307 AM EDT Monday...The main theme for late week into
next weekend is for a continuation of warmth and humidity across
the region as deep layer western Atlantic ridging holds semi-
permanent offshore. This will keep a steady flow of moist south
to southwesterly flow across our region with near daily chances
of showers and a few storms, not uncommon for early August. This
is not to say that it will be a washout on any of these days,
just to say the threat is certainly non-zero with highest
coverage in the afternoon to early evening during and just after
peak heating. Given the expected scattered nature of the
activity afternoon PoPs will generally range from 30-40% on
Thursday/Friday, then slightly lower (20-30%) by next weekend as
deeper heat and some evidence of building subsidence aloft
drift into the area. As discussed above, it will certainly feel
quite warm and humid with daily highs in the 79-86 range
Thu/Fri, then well into the 80s to locally near 90 in warmest
spots by the weekend. Lows to range mainly through the 60s to
lower 70s. With these trends, it seems a safe bet to assume the
A/Cs will be running steadily through much of the Thu-Sun time
frame.
&&
.AVIATION /07Z MONDAY THROUGH FRIDAY/...
Through 06Z Tuesday...VFR conditions will largely persist
through the next 24 hours with locally dense fog developing
across eastern Vermont valleys tonight. Only terminal to be
affected by fog will be KMPV where LIFR is expected from
08-12Z. After 12Z, we'll see more fair weather cumulus clouds
develop through the day and continue into tomorrow night. Light
and variable winds overnight will trend south/southwesterly
<10 kts during the afternoon and back to nearly calm after 00Z
Tuesday.
Outlook...
Tuesday: VFR. Chance SHRA, Chance TSRA.
Tuesday Night: Mainly VFR, with local MVFR possible. Likely SHRA,
Chance TSRA.
Wednesday: Mainly MVFR, with areas VFR possible. Likely SHRA,
Chance TSRA.
Wednesday Night: VFR. Chance SHRA, Chance TSRA.
Thursday: VFR. Chance SHRA, Chance TSRA.
Thursday Night: VFR. Slight chance SHRA, Slight chance TSRA.
Friday: VFR. Chance SHRA, Slight chance TSRA.
