Area Forecast Discussion National Weather Service Burlington VT 144 AM EDT Mon Jun 17 2024

SYNOPSIS
The pleasant weekend we experienced will be a distant memory soon enough. Temperatures warm sharply over the next couple of days leading to the warmest temperatures seen in the area in several years. Be sure to take appropriate precautions to avoid heat stress Tuesday through Thursday.

NEAR TERM /THROUGH TUESDAY/
As of 139 AM EDT Monday...Main change was to increase shower coverage for the early to mid morning hours as a front moves by the region. Mainly looking at sprinkles to a few hundredths as the front moves through from 6-11 AM. Otherwise, the forecast remains on track.

Previous Discussion...High clouds have built into the CWA over the past several hours. These clouds along with southerly winds will keep temperatures considerably higher than we saw last night. A weak warm front will pass through Northern New York and Vermont on Monday, with high temperatures close to 10F warmer than today. Areas close to the Canadian border will have a chance of showers overnight, spreading into the Dacks by Monday morning. These scattered showers will not linger and lift out by Monday afternoon.

SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/
As of 339 PM EDT Sunday...
HEAT ADVISORY IN EFFECT FROM NOON TUESDAY TO 8 PM EDT THURSDAY...

* Key points: A prolonged period of dangerous to potentially extreme heat is expected across the majority of the North Country and all of Vermont Tuesday through Thursday. This is a rare and potentially life threatening event for our region, with little to no overnight relief expected. Impacts are likely to some health systems, heat sensitive industries, and infrastructure.

The forecast remains relatively unchanged for the period with an anonymously strong near 560dm 500mb ridge situated to our south through the period, with daily rises of 925mb temperatures to +25- 27C along the spine of the Appalachians and points westward. With efficient mixing to 925mb and above, high temperatures are expected to rise to near or above record levels in the 90s, with ensemble probabilities still flirting with the potential for a few 100s on Wednesday. Adding to the heat are PWATs in excess of 150% of normal which will be felt at the surface as dewpoints in the upper 60s to low 70s which will result in heat indices in excess of 95 degrees, and potentially up to 105 degrees for portions of the Champlain, St.
Lawrence, and southern Connecticut River Valleys. Adding to the misery is that overnight lows won't provide much relief, only falling off into the upper 60s to low 70s, which provides a cumulative impact to the heat. Experimental NWS Heat Risk highlights all of this well, forecasting major to extreme heat conditions across the region, and warrants people to be extra vigilant of your health, drinking plenty of water and avoiding prolonged strenuous activity during the hottest time of day. Be sure to check up on your family, friends, neighbors, and those most vulnerable to heat.

The threat for precipitation is additionally non-zero through the period, though the likelihood is low outside of the chance for an isolated storm to develop on the daily lake breeze or over the Adirondacks. If something could get going though, the potential for heavy rain and/or a wet microburst does exist given how juiced the airmass will be. The best chance for any precipitation will be on Thursday as a weak pre-frontal trough approaches from the north and could provide enough synoptic support near the international border to produce isolated to scattered storms.

LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/
As of 339 PM EDT Sunday...A much welcomed front arrives Thursday night into Friday providing relief from the heat, and likely scattered showers and thunderstorms. Timing of the front remains uncertain, and an earlier arrival Thursday evening/night could provide greater potential for stronger storms across northern zones, while southern areas will see the best chance Friday afternoon. High pressure builds into the region briefly for Friday night, with rising chances for showers and thunderstorms on the weekend.

AVIATION /06Z MONDAY THROUGH FRIDAY/
Through 06Z Tuesday...VFR conditions will likely prevail through the period with best chances of MVFR with showers 10-16Z as a weak front moves through the region. Upstream radar shows ample returns, but decaying as they move into the ridge; thus can't rule out scattered showers for MSS/BTV/EFK/PBG/SLK. Thunderstorm chances are less than 10%, so left those out for now. Otherwise, winds will be south/southwest with gusts 15-25kts after 10Z. MSS could see a brief window of LLWS with the glancing front that tracks through 10-14Z.

Outlook...

Tuesday: VFR. NO SIG WX.
Tuesday Night: VFR. NO SIG WX.
Wednesday: VFR. NO SIG WX.
Wednesday Night: VFR. NO SIG WX.
Thursday: VFR. Chance SHRA, Chance TSRA.
Thursday Night: Slight chance SHRA, Slight chance TSRA.
Friday: Chance SHRA, Chance TSRA.
