Area Forecast Discussion
National Weather Service Burlington VT
411 AM EDT Thu May 17 2018

.SYNOPSIS...
A dry cold front will slowly move through the region this morning 
and afternoon bringing with it near to slightly below average 
temperatures. This weekend will see rain move in as low pressure 
lifts northeastward from the Ohio Valley into New York and New 
England. Next week will see a return to drier conditions and above 
normal temperatures.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 402 AM EDT Thursday...This morning will bring a dry cold front
out of Canada will just a remote chance of precipitation this 
morning. Hi-res models show small window after sunrise for a
brief, passing shower, but any area that sees anything will be 
looking at a trace amount at best. Expect the winds to shift to
the north this morning as the front slides south through the 
CWA. Along with the wind shift, a drier airmass with cooler 
temps which will lead to highs this afternoon about 5-7 degrees 
cooler than Wednesday, but still right near seasonal normals. 

Thursday night should be dry as well as skies clear and temps 
cooling quickly into the low to mid 30s, and possibly mid 20s in 
parts of the Dacks, so we'll need to continue to monitor for frost 
potential but no fog is expected.

Dry weather continues for Friday as high pressure settles in behind 
the front. While skies will remain relatively cloud free, 
especially across the northern counties, northerly flow will 
continue, for most of the day, keeps high temps again right near 
seasonal normals.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 408 AM EDT Thursday...The ridge aloft over the Northeast 
breaks down and high pressure will move east of Maine and 
Canadian maritimes Friday night into Saturday. A cool and 
increasingly moist low-level southeast return flow becomes 
established by Saturday morning as a warm front develops to our 
southwest. 

Good strong warm advection and moisture convergence is evident 
Saturday at 925/850 mb as winds increase to 30 to 50kt leading to 
modest QG forcing. This along with a surge of 1.50" of precipitable 
water will bring about rain moving in from southwest to northeast 
overspreading the entire region between 12 and 18z Sat. Rain will 
become more showery in nature Saturday night as the best warm 
advection and overrunning lifts northeast of the area during the 
overnight hours. Some of the area especially in northern NY may get 
into the warm sector while east of the Greens its less likely.  The 
NAM is showing some CAPE of 250-500 J/kg in NY, mainly elevated 
while the GFS is less. Showalter nears zero and Ks in the 30s, so 
thunder is not out of the question, but averaging NAM/GFS have left 
out thunderstorms at this point, but something to watch in later 
forecasts.  Its looking like about a half inch of rain is expected 
with locally 0.75 to near an inch over the south central Greens. 

Temperatures a bit tricky.  First Friday night as it will start out 
mainly clear and calm but high clouds increase the second half of 
the night. Going with lows mostly in the 40s but could be some 30s 
in the north, perhaps near freezing in the northern Adirondacks and 
NEK of VT.  Saturday looking at cool highs mainly in the 50s perhaps 
touching 60 in the north in the  morning before the rain moves in 
and temperatures fall a bit. Some of the model temperatures even 
suggest the higher terrain in the south could be in the upper 40s 
for highs on Sat. Little change in temps for Saturday night with 
lows ranging from the upper 40s east of the greens to mid 50s in the 
St. Lawrence valley.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 408 AM EDT Thursday...Some showers will linger Sunday as 
a weak cold front moves through behind departing low pressure. 
Monday is looking dry right now with a NW flow aloft and weak 
high pressure. Things become a bit more uncertain next week as 
the flow aloft backs to more westerly with perhaps a weak short 
wave or two embedded for another chance of showers Tuesday into 
Wednesday. Temperatures continuing close to average with highs 
in the upper 60s to lower 70s and lows in the 40s to around 50 
each day. 

&&

.AVIATION /08Z THURSDAY THROUGH MONDAY/...
Through 06Z Friday... Expect VFR Conditions overall for the 
period. Exceptions will be KRUT with MVFR ceilings over the next
few hours and KSLK/KBTV/KMPV possibly seeing MVFR as well right
around sunrise for an hour or two as front to our north begins 
to sag south. Any MVFR ceilings should lift through the morning 
hours as drier air moves in with VFR conditions expected through
the remainder of the period. 

LLWS is expected over the next few hours at all stations with 
decent pressure gradient and 35 to 40 kt jet at 2000ft and 
lighter surface winds. Southerly winds overnight will veer to 
the NW around 5-10 kt as front moves through the area between 
11-13z. 

Outlook...

Friday: VFR. Patchy BR.
Friday Night: VFR. NO SIG WX.
Saturday: Mainly MVFR, with areas VFR possible. Chance SHRA.
Saturday Night: Mainly MVFR, with areas IFR possible. Chance
SHRA.
Sunday: Mainly MVFR, with areas IFR possible. Chance SHRA.
Sunday Night: VFR. Slight chance SHRA.
Monday: VFR. Slight chance SHRA.
