Area Forecast Discussion National Weather Service Burlington VT 515 AM EDT Mon Sep 21 2020

SYNOPSIS. Our streak of quiet weather continues through most of the week. High pressure remains over the area. Hurricane Teddy approaches the Canadian Maritimes on Wednesday and we'll only see an increase in winds beginning Tuesday afternoon. Next chance at any significant precipitation for Northern New York is sometime early next week. Temperatures will return to seasonal normals or slightly warmer from Wednesday onward.

NEAR TERM /THROUGH TUESDAY/. As of 455 AM EDT Monday . With high pressure remaining over the north country from today through Tuesday, dry and quiet weather will continue. Temperatures will remain a bit below seasonal normals through the near term with highs in the upper 50s to lower 60s today, and a few degrees warmer than that on Tuesday. Tonight will be the last overnight with temperatures cold enough for frost formation, with some areas dropping below freezing. On Tuesday will have an increase in winds, especially across our Eastern zones as Hurricane Teddy approaches the Canadian maritimes making landfall around Wednesday morning. Will see some smoke make it over our area once again today and tomorrow, though mainly in the higher levels of the atmosphere. This will give the sky a somewhat milky appearance, and resulting in some filtered sunshine. Have tried to account for this in the forecast by increasing sky cover grids based on the HRRR smoke output.

SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/. As of 455 AM EDT Monday . Dry weather conditions are expected to persist Tuesday night into Wednesday with PoPs <10% throughout the period. Will see an increase in N-NW mid-level flow, with some potential increase in mid-level cloud cover, especially during the daylight hours on Wednesday per GFS/NAM mid-level RH fields. Lows Tuesday night generally in the low- mid 40s, except upper 40s in the immediate Champlain Valley. Highs for Wednesday afternoon generally expected in the 65-70F range, with a few valley locations in the lower 70s. Some modest increase in nwly gradient flow is expected, with winds generally 10-15 mph and a few gusts closer to 20 mph, especially east of the Green Mtns. Downslope flow component will aid in adiabatic warming and highs into the lower 70s across the CT River Valley Wednesday afternoon.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 455 AM EDT Monday . Main theme during the long-term period will be moderating temperatures and continued absence of significant precipitation chances. Continues to appear that weak mid-level shortwave trough in WNWLY flow will bring mostly cloudy conditions on Thursday, but with just a slight chance of showers, mainly across far nrn NY into nrn VT. Thereafter, mid-upper level flow pattern becomes increasingly amplified. With 850mb temperatures moderating to +9 to +10C, should see valley highs reach the lower 70s. Should see low-level flow regime turn S-SW Friday through Sunday as mid- level ridge builds newd from the Ohio Valley into NY/New England. Trended highs into the mid 70s for Friday and upper 70s in valley locations for Saturday (MEX-MOS shows 80F possible at BTV). Slow- moving closed low and surface frontal zone shifting ewd across the Ohio Valley on Sunday will result in potentially breezy conditions Sunday with south winds 15-25 mph and gusts to 30 mph possible. Should again see temperatures 75-80F for afternoon highs. Appears precipitation with upstream frontal system will hold off until Sunday night or Monday per 00Z GFS, and forecast currently follows this soln.

AVIATION /09Z MONDAY THROUGH FRIDAY/. Through 06Z Tuesday . VFR conditions will persist through the period under mainly clear skies. Some smoke will filter into the region from the north overnight and through Tuesday, but will remain aloft above 20,000 feet. No restriction to flight category is expected at the surface. Winds will be light through the period, except 5-10kts from the southeast at KRUT overnight, and during the day at KPBG. Added in some BR in a tempo group at MPV from 8-12z as we've had some BR develop there the last couple mornings and with clear skies and light winds anticipated this will happen again.

Outlook .

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

BTV WATCHES/WARNINGS/ADVISORIES. VT . Frost Advisory until 8 AM EDT this morning for VTZ005-009-018- 019. NY . Frost Advisory until 8 AM EDT this morning for NYZ028-035.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
