Area Forecast Discussion
National Weather Service Burlington VT
250 AM EDT Wed Aug 19 2020
.SYNOPSIS...
Other than a widely scattered shower here and there this
afternoon, mainly dry weather is expected today under partly
sunny skies. Dry weather will continue from Thursday into
Saturday under building high pressure and warming temperatures.
The next chance of significant rainfall occurs by Sunday into
Monday of next week.
&&
.NEAR TERM /THROUGH THURSDAY/...
As of 250 AM EDT Wednesday...The base of a large longwave upper
trough remains across the Northeast this morning with light
surface winds bridged by cyclonic flow aloft. A final and rather
unremarkable shortwave embedded within this flow will swing
through the region this afternoon with little fanfare other than
a few/isolated showers. Overall forcing remains rather weak so
chances of measureable precipitation should be on the low side -
mainly from 10-25% in the noon to 6 pm time frame. Highs remain
seasonably mild from the upper 60s to mid 70s.
The upper trough then lifts out to the northeast tonight into
Thursday as surface high pressure builds east from the Great Lakes.
As such, we're looking at a mainly clear to partly cloudy period and
continued mild temperatures, perhaps 2 to 4 degrees warmer for
afternoon highs. Winds mainly light. PoPs nil.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/...
As of 250 AM EDT Wednesday...Fairly quiet for Thursday night.
Some increasing clouds as a subtle shortwave feature over the
Great Lakes accelerates into confluent upper flow across New
England. It still looks like a weak surface trough will move
along an axis of moist flow and zonal 700mb flow while a
vigorous shortwave digs across the mouth of the St. Lawrence
River. Light southerly winds near the surface will advect some
warmer air into the region to combat diurnal cooling. We should
see temperatures fall to the mid to upper 50s for much of the
region with cooler temperatures in the Northeast Kingdom, where
it will take some time before warmer air advects into the
region.
During the day on Friday, we'll see another upper shortwave quickly
shift east out of Ontario and catch up with the surface trough
moving slowly across Quebec Province. Along with diurnal
instability, this should spark scattered showers and thunderstorms,
mainly along and north of the International Border. Much of Vermont
and the Adirondacks will remain dry, as a narrow axis of drier air
resides south of the better moisture and dynamics streaming across
eastern Canada. Highs will be dictated somewhat by cloud cover. More
clouds along the International Border and the chances for
precipitation should keep max temperatures warmest in the southern
valleys with low to mid 80s. Elsewhere, mid to upper 70s are
expected.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 250 AM EDT Wednesday...There continues to be general
disagreement on how things play out the remainder of the
weekend. Several systems will continue to steadily slide their
way eastwards within west-northwesterly upper flow. Disagreement
on location, forward speed, and how amplified weak shortwaves
become while embedded within general high latitude troughing
continues to make determining the best time frame for showers
and thunderstorms a challenge. It still appears we will have one
shortwave trough push through sometime Friday night into
Saturday that should drive some showers. Outside of that, it
looks like a warm layer aloft will prevent afternoon convection
across the region.
Then a pair of additional shortwaves will bring better precipitation
coverage for Sunday and Monday. There should be a breaks in
precipitation throughout the period, but progressive flow will keep
a continual stream of systems through the area. General track of
these features across Canada should give the best precipitation
chances along the International Border. 7-Day rainfall accumulations
highlight our northern tier. So, despite the forecast headaches of
timing each of these features, it looks like our northern tier will
see beneficial rains.
&&
.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
Through 06Z Thursday...A mix of VFR and IFR depending on
terminal through 12Z due to patchy fog. Terminals experiencing
IFR/LIFR will be KMPV/KSLK and possibly KRUT with other sites
remaining mainly VFR through the forecast period. Weak trough
passage this afternoon may spark and isolated shower or two with
SCT to BKN cigs in the 045-090 AGL range, but coverage scant
enough to warrant no mention in the terminal forecasts at this
time. After 00Z skies trend mainly SKC. Light winds through 12Z
trend west to northwesterly from 5-10 kts by later this morning
into this afternoon, then abate to near calm once again after
00Z.
Outlook...
Thursday: VFR. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: VFR. Slight chance SHRA.
Friday Night: VFR. Slight chance SHRA.
Saturday: VFR. Slight chance SHRA.
Saturday Night: VFR. Slight chance SHRA.
Sunday: VFR. Chance SHRA.
