Area Forecast Discussion
National Weather Service Burlington VT
355 AM EDT Fri Apr 24 2020
.SYNOPSIS...
Other than variable clouds and a passing light rain or snow
shower across far southern Vermont through early afternoon, dry
weather is expected into Sunday morning as high pressure across
southern Canada holds firm. Chances of precipitation increase
steadily by Sunday afternoon into Sunday night as low pressure
lifts into the region.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 316 AM EDT Friday...The forecast is panning out largely
as expected as low pressure passes to our south today.
Precipitation has struggled to push north into our area due to
very dry boundary layer air associated with Canadian high
pressure centered off to our north/northwest. Latest global and
hi-res guidance maintain this idea today, keeping primary threat
of steadier light rain/snow shower activity off to our south.
As such have maintained only low chances of precipitation across
our far southern VT counties through the mid morning to early
afternoon hours. Further north dry conditions will continue.
Temperatures will be a bit tricky due to variable cloud cover,
though the running idea of slightly milder north (l-m 50s) under
filtered/partial sunshine still looks reasonable. Slightly
cooler readings (mid 40s to around 50) are expected south under
thicker, more persistent cloud cover.
Clear to partly cloudy skies return area wide tonight as today's
system edges offshore and aforementioned high settles across the
region. This will set the stage for an outstanding weather day on
Saturday with full sunshine, light winds and seasonably mild
temperatures from the mid 50s to around 60.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 352 AM EDT Friday...The short term is initially quiet. This
doesn't last long. Clouds will be increasing throughout the evening
hours as two shortwaves begin to phase over the Ohio River Valley.
This will lead to near normal low temperatures, with most areas in
the mid to upper 30s. Precipitation chances will begin to steadily
creep upwards towards dawn on Sunday. Low-level dry air will need to
be overcome first before precipitation can reach the ground, though,
so have kept PoPs in the chance to slight chance category during the
morning. By afternoon, much of the dry air is filtered out and
vertical motion will begin to increase as a strong warm front lifts
into the region. Dry air is likely to hang in longer north of the
front, keeping areas along the International Border, especially the
St. Lawrence Valley, drier. This warm front will be enhanced by
strong baroclinicity from a 1030mb high centered near James Bay in
Canada and strong warm advection ahead of an occluded low and
secondary development east of the Appalachians. This will be
supported by a well-defined deformation axis along with a coupled
jet structure. The strong omega fields are thus reasonably expected.
A band of moderate to locally heavy rain should develop along this
potent warm front and lift northwards Sunday afternoon into Sunday
evening, pivoting once it reaches the Dacks and Southern Vermont.
North of the warm front will be an easterly 40-45kt LLJ develop to
the north of the low. This should keep us in a cool, maritime air
mass with highs likely staying in the 40s for the day, though a few
spot 50s seem reasonable as well. How warm low-level temperatures
are and precipitation trends will need to be watched for potential
gusts for western slopes of the Southern Greens. The overall thermal
profile and mesobanded precipitation will be something to keep an
eye on as well. Strong diabatic cooling could allow for some snow to
mix in with rain at times during the heaviest precipitation Sunday
evening across Rutland/Windsor Counties in addition to the higher
elevations.
Upper low lingers across the region into Monday with cold air
advection behind the surface low now off the New England Coast. This
will keep the day showery, with snow levels around 1500-2000ft
elevation. Temperatures are also likely to remain sub-50 into Monday
for highs. A preliminary forecast (to be revised) indicates
less than 0.3" for the St. Lawrence Valley, 0.33"-0.5" across
Northern Vermont, and 0.5"-1" across the remainder of Vermont
and in the Adirondacks with the highest amounts along the
eastern slopes of the Greens and Adirondacks.
&&
.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
As of 352 AM EDT Friday...For Monday night, the upper low will
finally take its leave of our area and showers will begin to
gradually diminish. Tuesday afternoon will trend drier and warmer as
a narrow shortwave ridge amplifies between the departing upper low
and an amplifying shortwave in the Mississippi River Basin.
Wednesday will be pick of the week, with the warmest and driest
conditions. Late Wednesday, another upper low will begin to encroach
upon our area. Some timing differences exist on when the bulk of
precipitation arrives, but the better chances look to be on
Thursday. This system also looks dynamically vigorous, with early
outlooks suggesting an efficient moisture tap. We shall see how it
plays out.
&&
.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
Through 06Z Saturday...VFR through the forecast period under
SCT/BKN mid to high level cigs. Winds light and vrb through 14Z,
trending light north to northeasterly from 4-8 kts by Friday
afternoon, then near calm again after 00Z. An outside shot of a
brief light shower/sprinkle at KRUT in the 12-18Z time frame but
scant coverage warrants omission at this point. Dry elsewhere.
Outlook...
Saturday: VFR. NO SIG WX.
Saturday Night: VFR. Chance SHRA.
Sunday: Mainly VFR, with local MVFR possible. Chance SHRA.
Sunday Night: Mainly MVFR, with areas VFR possible. Chance SHRA.
Monday: Mainly MVFR, with areas VFR possible. Chance SHRA.
Monday Night: Mainly VFR, with areas MVFR possible. Slight chance
SHRA.
Tuesday: Mainly VFR, with local MVFR possible. NO SIG WX.
