What forecasters said that day
The local office's own words before this heat advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Burlington, VT wrote its last area forecast discussion before this heat advisory went out at Aug 9, 1:20 PM EDT, 2 hours 2 minutes earlier.
Area forecast discussion, Aug 9, 1:20 PM EDT, 2 hours 2 minutes before
Area Forecast Discussion National Weather Service Burlington VT 120 PM EDT Mon Aug 9 2021 .SYNOPSIS... A warm front will lift across the region early this morning, allowing hot and humid air to rebuild into the region for the rest of this week. Mainly dry conditions are expected on today and Tuesday with better thunderstorm chances from midweek onward. The best chance of widespread showers and thunderstorms will be Friday and Friday night as a cold front will push across the region. This front will finally bring relief from the heat and humidity, making for a nice weekend. && .NEAR TERM /THROUGH TUESDAY/... As of 916 AM EDT Monday...Forecast remains in good shape as of mid morning. Only notable adjustment was to increase cloud cover across northern NY through the morning hours based off current satellite imagery and modelled 700-500 RH progs. Have a great day! Previous discussion...The main emphasis for the near term will be very warm and humid conditions which will persist through much of the week. A warm front will push into Canada early this morning, spreading a very warm and muggy airmass into the North Country. Temperatures today will top out in the mid and upper 80s, with some locations in the St Lawrence and Champlain Valleys approaching 90. Tuesday will be even warmer with most spots in the mid 80s to lower 90s. Meanwhile, dewpoints will remain in the mid 60s to close to 70, making for heat index values in the mid 80s to lower 90s today, and the mid 80s to mid 90s tomorrow. The warm temperatures and high dewpoints will also result in increasing instability; CAPE values will be 500-1000 J/kg each day. This may be enough to allow a few showers and thunderstorms to pop up over the higher terrain this afternoon, though without any upper support, coverage and intensity will be quite limited. Tuesday, a weak upper shortwave will approach the St Lawrence Valley from the Great Lakes region late in the day, so chances for showers/thunderstorms will be a little better than today, though still anticipate scattered coverage at best. Regardless, given PWATs will once again be in the 1.50-1.75 inch range, any convection will be capable of producing heavy downpours. What showers/thunderstorms do develop today will wane this evening as we lose heating, but there won't be any relief from the humidity; it'll be a muggy night with lows remaining in the 60s to around 70. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... As of 325 AM EDT Monday...As mentioned yesterday...a shortwave in the Great Lakes will largely lift ENE across Ontario/Quebec with the best forcing and an associated weak surface trof drifts east with waning instability due to loss of heating thus a few remaining showers diminishing during the night across northern NY. This trof lies across CWA on Wed along with PWATS 1.5-2 inches and NAM12 CAPE values 1500-2500. Model soundings show a marginal cap and with no real forcing other than surface heating it looks like a lot of wasted cape and rich PWATS. Isold SHRA/TSRA likely terrain driven, otherwise just continued Hazy, Hot and Humid with 925mb temps 23-26C with some indications up to 27-28C. I'll play it conservative with L90s but can't rule out some M90s. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... As of 325 AM EDT Monday...Weak shortwave in W flow moves through Wed night with decreasing instability due to loss of daytime heating YET still some octane to this atmosphere. Can't rule out an isold shra/tsra esp northern NY. Again, mentioned yesterday broad W flow across Canadian border due to elongated W-E heat ridge across lower half of CONUS and cold, winterlike strong upper low in Hudson Bay. On Thursday...strengthening WSW flow parallel to boundary just E of FA and the main cold front across Quebec/Ontario/Great Lakes. Therefore not much change in the airmass, 925mb temps 22-26C (warmest across VT) with PWATS 1.5-2 inches. A pre-fntl trof and weak embedded shortwave approaches/moves through in the aftn for sct thunderstorms. Friday will feature the cold upper low shifting east across Hudson Bay with rotating shortwave digging SSE across Ontario/Great Lakes/Quebec and eventually into our FA Friday afternoon. Strong dynamics and developing jet structure that this could be an active day. 925mb temps cooler, ranging from 20C in St. Lawrence VLY but still 25C in eastern VT and even with more clouds still L90s there. Medium range models consistent that strong >110 kt dual core 250mb jet and all strongest mid-level flow across Ontario/Quebec parallel to slow moving surface front across VT where PWATS of 1.5-1.75 inch riding along it and GFS/ECMWF still showing potential weak wave(s) developing along this front for Friday evening/ngt. Still early, but many features coming together for training storms and good synoptic lift for potential flood threat...esp VT eastward. By the weekend...AWE! Yes, Mother Nature's AC arrives with seasonable temperatures and refreshing dewpoints. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... Through 18Z Tuesday...A mix of VFR/MVFR over the forecast period. VFR in order through 04Z with scattered high clouds, mixed with some scattered cigs in the 035-045 AGL range at KMPV/KEFK/KRUT. Winds mainly south 6-12 kt through 00Z, abating somewhat overnight. Can't completely rule out an isolated shower or storm through 01Z, but paucity of coverage warrants no mention in the forecasts at this point. After 04Z maritime stratus likely to push west into eastern VT, affecting mainly KMPV/KRUT. Some IFR in BR/FG possible early at KMPV before stratus arrives, with visibilities thereafter mainly 3-5sm. Elsewhere, VFR continues. After 12Z Tuesday, lower stratus gradually lifts at KMPV/KRUT where a trend to VFR shown, with other terminals remaining VFR with just scattered mid/high clouds. Winds generally remain southerly in the 5-10kt range. Outlook... Tuesday Night: VFR. Chance SHRA, Chance TSRA. Wednesday: VFR. Chance SHRA, Chance TSRA. Wednesday Night: VFR. Chance TSRA, Slight chance SHRA. Thursday: VFR. Chance SHRA, Chance TSRA. Thursday Night: VFR. Chance SHRA, Chance TSRA. Friday: VFR. Chance SHRA, Chance TSRA. Friday Night: VFR.
