Area Forecast Discussion National Weather Service Burlington VT 322 PM EDT Sat Jun 15 2024

High pressure building into the Northeast will provide a clear cool night tonight, and partly cloudy skies Sunday along with low humidity. Unfortunately, this nice weather will be short-lived as a long-duration heat event moves in next week with several days of highs in the 90s, dewpoints in the upper 60s to low 70s, and warm overnight lows in the 60s and 70s. Heat related impacts are likely.

As of 320 PM EDT Saturday...Surface high pressure will crest over the North Country and Vermont tonight providing clear and unseasonably cool conditions with lows widespread through the 40s and some isolated spots in the 30s. Isolated frost is possible in the hollows of the Adirondacks and Northeast Kingdom of Vermont, but coverage is not high enough to warrant any headlines. Dry conditions continue through Sunday night, but as an upper ridge approaches from the west, mid/high clouds will increase early Sunday and become scattered to broken through the day and into Sunday night. Dry conditions will prevail through much of Sunday night, but some isolated showers are possible along the international border during the pre-dawn hours of Monday as weak shortwave energy rides over the ridge. Highs Sunday will warm back towards seasonal normal sin the 70s, and lows Sunday night will follow suit, perhaps a couple degrees above normal in the 50s to low 60s.

As of 320 PM EDT Saturday...A shortwave trough will be crossing to the north of the forecast area early Monday, allowing for a few showers along the international border before ridging builds into the region to shut that off later Monday. The chance of precipitation will be about 10- 30% throughout the day, and any precip will most likely be in the form of isolated showers, though a rumble of thunder is not out of the question in the afternoon.

The more noticeable weather will be decreasing cloud cover and rising temperatures to mark the start of a very warm week. Highs Monday will be in the lower to mid 80s, roughly 5-10 degrees above climatological normals. Relative humidity values will be somewhat moderate in the 40-60% range during the peak of heat. Monday night will not provide much relief or cool down, unfortunately, with lows expected to fall into only the 60s, about 10-15 degrees above average.

As of 320 PM EDT Saturday...We continue to monitor an anomalously strong ridge over the forecast area next week, producing high temperatures 90+ Tuesday through Thursday with some lingering 90+ highs on Friday for some.

For Tuesday, some of the higher resolution models are starting to coming in as well, indicating 90+ remains isolated to the wider valleys like the St. Lawrence and Champlain, with upper 80s elsewhere. However, the majority of models continue to suggest widespread 90+ outside of the higher peaks Tuesday with projected temperatures increasing slightly from what they were 12 hours ago.
The Canadian and GFS models are suggesting there could be some ridge rider showers throughout the week, which could dampen temperatures.
The GFS in particular continues to hold onto slightly "cooler" temperatures than other models, with expected highs in the 80s to lower 90s Tuesday and Wednesday. ECMWF remains on the higher side of the global models.

Regardless of precise numbers, humidity could make it feel much warmer than the forecast says, with heat indices around 100 or so each afternoon Tuesday-Thursday. In addition to daytime heat, nights next week will not provide relief with lows in the mid 60s to lower 70s Tuesday night through Thursday night. For these reasons, we have been placed in the Major and Extreme Heat Risk categories across the forecast area. Plan on dangerous heat next week. Some ways to mitigate these hazardous conditions include limiting outdoor activities, knowing where your local cooling centers will be, especially if you have no AC at home, and staying hydrated.

If we do indeed get some ridge rider forcing next week as the GFS depicts, we will be on the lookout for severe thunderstorms as the atmosphere would be well primed for severe weather with heat, instability, and moisture streaming north from the Gulf of Mexico.
Extreme heat looks to finally breakdown next weekend after a cold front drops through around the Friday time frame with some associated precipitation possible. Still, highs will be in the 80s for most following the front.

Through 18Z Sunday...VFR conditions will generally prevail through the period with VCFG possible at KMSS from 06-11Z.
Otherwise, fair weather cumulus across the area this afternoon around 5000 feet will dissipate through the afternoon with skies SKC through midnight, before high clouds begin to filter in from the west, becoming SCT-BKN after 12Z Sunday. Gusty NNW winds up to 25kts this afternoon rapidly abate towards 00Z to calm overnight, and variable less than 5kts Sunday.


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

Hot temperatures will result in values near records by the middle of next week. Below are some of the records under threat of being broken.
