Area Forecast Discussion National Weather Service Burlington VT 734 AM EDT Sun Sep 19 2021

SYNOPSIS. Dry and unseasonably warm conditions prevail through early next week with temperatures warming into the low 80s for some locations. A large scale weather system is expected to traverse the Northeast by weeks end bringing chances for widespread rain and a sharp cooldown in its wake.

NEAR TERM /THROUGH MONDAY/. As of 710 AM EDT Sunday . Only minor changes to the forecast based on latest observations. Increased cloud cover locally over Burlington and south into Addison County as a lake band has developed downstream of Lake Champlain this morning. Based on NAM3 sounding profiles, temperatures aloft at ~1500ft are around 10C and latest lake ob shows water temps of 68F. This give a delta around 18 degree supporting the development of this cloud. As daytime heating commences the temperature difference should lessen therefore expect this cloud to dissipate within a couple hours. Additionally, valley fog and low stratus will erode by mid-morning as well with clear skies for the remainder of the day. Going forecast has this all well covered so no other changes were needed.

Previous Discussion . Not too much to say about the weather over the next 36 hours as high pressure exists throughout the entire atmospheric column. Areas of fog/low stratus this morning will erode by mid- morning with blue skies and full sunshine today. Temperatures will be comfortably seasonable in the mid 60s to low 70s for the valleys and mid/upper 50s for the higher terrain. Winds will be generally light out of the N/NW around 10-15 mph. Tonight, clear skies and light winds will allow for ideal radiational cooling conditions. Lows will drop into mid 30s to mid 40s, with around 50 likely along the immediate Lake Champlain shoreline. A few pockets of frost are possible across the Adirondacks and Northeast Kingdom. For Monday, expect the same clear and sunny skies with temps a few degrees warmer in the low to mid 70s as winds turn out of the south.

SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/. As of 424 AM EDT Sunday . Deep-layer ridge remains in control Monday night into Tuesday while slowly drifting east of New England across the Gulf of Maine and Nova Scotia. Will see a developing low-level southerly return flow during the period. This will contribute to warmer overnight lows compared to recent nights. Lows Monday night generally low-mid 50s in the Champlain and St. Lawrence Valleys, and mid-upper 40s elsewhere. Mostly sunny and breezy conditions will characterize Tuesday. Looking for south winds 15-25 mph with a gusts 30-35 mph possible in the Champlain Valley. A Lake Wind Advisory may be required for Lake Champlain. High temperatures Tuesday generally expected in the mid 70s, but a few values near 80F are possible in the St. Lawrence Valley region. PoPs NIL.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. As of 424 AM EDT Sunday . Highly amplified mid-upper level flow pattern expected in place for mid-late week across the eastern third of the CONUS and western Atlantic. We'll be watching closely the ewd progression of slow- moving mid-level trough expected across the Great Lakes and Ohio Valley at 12Z Wednesday. Both the deterministic 00Z GFS and ECMWF develop this system into a cutoff low to our west Wednesday night into Thursday, and overall trend continues to be a slower arrival of precipitation into the North Country. Likewise, 00Z CMC-GEM has also trended slower with a cutoff low in vcnty of the upper Ohio Valley at 12Z Thursday, and mid-level ridge holding strong east of New England.

As such, have indicated breezy and warm conditions across the region on Wednesday with highs in the mid-upper 70s. May see southerly wind gusts up to 35 mph in the Champlain Valley on Wednesday. Included just a chance of showers across St. Lawrence County NY Wednesday afternoon. Overnight lows will be well above normal both Tuesday night and Wednesday night given southerly gradient flow. Mainly followed 00Z GFS with occulded front moving across our region later Thursday into Thursday night, with PoPs 60- 70% for rain during this period. The 00Z ECMWF would suggest a slower arrival of frontal precipitation by 12-24 hrs (mainly Thursday night into Friday). We'll need to watch for continued breezy conditions in advance of the frontal passage, especially in the Champlain Valley. Given strength of frontal forcing, may also see some embedded convective elements/thunderstorms as the front moves through Thursday/Thursday night (based on present indications). Trending drier and slightly cooler for Friday and Saturday with highs in the upper 60s to lower 70s.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. Through 06Z Monday . LIFR/VLIFR fog and stratus this morning will lift to VFR with minimal clouds today. Tonight expect similar reductions as valley fog returns at favored terminals (KSLK, KMPV & KEFK) after 06z. Calm winds this morning will trend northwest winds 4 to 8 knots on Sunday. Winds will decouple and trend light variable/calm after 00z.

Outlook .

Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: VFR. NO SIG WX. Tuesday Night: VFR. NO SIG WX. Wednesday: Mainly VFR, with local MVFR possible. Slight chance SHRA. Wednesday Night: Mainly VFR, with areas MVFR possible. Chance SHRA. Thursday: Mainly MVFR, with areas VFR possible. Chance SHRA.
