Area Forecast Discussion National Weather Service Buffalo NY 1055 PM EDT Sun Jun 16 2024

Heat and humidity builds Monday and last through at least Thursday.
Apparent temperatures during this time will likely reach 100F at some locations Tuesday and Wednesday. There will also be a chance of a few isolated showers or a thunderstorm well inland from the lakes each day. Some relief from the oppressive heat begins Friday into the weekend.

A warm frontal segment will pass by to our north, and this will begin to bring in a more humid air mass. This frontal passage will also bring a small chance of showers, mainly across the Eastern Lake Ontario region very late tonight into early Monday morning.

...Heat and humidity builds MONDAY and remains for much of the work week...


In the wake of the warm frontal passage temperatures on Monday will be notably warmer, and it will also be more humid. Apparent temperatures will rise into the upper 90s in the lower Genesee Valley and Western Finger lakes region, where a Heat Advisory was issued starting Monday. Elsewhere, will be hot with high temperatures in the upper 80s and apparent temperatures in the lower 90s.

For the most part, the day should be rain-free but some high res models do develop some isolated thunderstorms in the afternoon.
Given forecast soundings, it appears this is likely overdone and only supports a slight chance PoPs.


Dangerous Heat Wave Will Begin For The Region

Surface high pressure will be anchored over the Atlantic and a deep southerly flow will bring HOT and HUMID conditions during the day and WARM and HUMID conditions during the night Monday night through Wednesday night.

An anomalously strong upper level ridge will build across the eastern Great Lakes region and Northeast through mid-week. Warm air advection will take place Monday night through Tuesday with 850mb temperatures climbing to +20C. Very warm Monday night with lows in the upper 60s across the higher terrain and low 70s across the lake plains. Temperatures will soar into the low 90s across the region with valley locations reaching the mid to upper 90s Tuesday.
Dewpoints will climb into the upper 60s to low 70s with PWAT values 1.5 inches or greater. The combination of the heat and humidity will drive heat index values into the upper 90s to low 100s Tuesday afternoon. The forecast area will be on the northwest side of the strong upper level ridge and should be enough in the ridge to keep any upstream thunderstorm complexes outside the forecast area Tuesday. There will be high surface based instability across the region (sans the immediately shorelines.) Terrain circulations and lake breeze boundaries will likely produce a cu field with isolated to scattered showers and thunderstorms. Any convection will wane into the evening hours. The very warm airmass will persist through Tuesday night with overnight lows only reaching the low 70s.

There is little change in the sensible weather for Wednesday and Wednesday night. Another HOT and HUMID day with highs in the low to mid 90s, dewpoints in the upper 60s to low 70s, and heat index values in the upper 90s to low 100s. There is some model guidance that shows 850mb temperatures a few degrees higher (EC) which could add a degree or two to high temps Wednesday. The forecast area will remain on the northwest side of the upper level ridge Wednesday through Wednesday night. The convective potential is similar to Tuesday with low coverage of showers and thunderstorms. Another very warm night with lows in the low to mid 70s.

A Heat Advisory is in effect for the entire forecast area Tuesday through Thursday.

...Dangerous Heat Wave Will Continue For The Region Through At Least Thursday...

Model consensus shows the axis of the anomalously strong nearly 600 decameter ridge will be just to our south and southeast Thursday, just a slight jog from its position on Wednesday. This may bring 500 mb heights down just a smidge, along with surface temperatures/dew points possibly a couple of degrees cooler. All in all, very similar to the hot and steamy conditions expected for Tuesday/Wednesday, which will make Thursday the most oppressive day of the long term period with heat index values again ranging from the mid 90s to very low 100s for the bulk of western and northcentral NY.

Positioning/proximity of the upper level ridge will suppress most, if not all convection, especially across western NY. Better chance for an isolated shower/storm would be toward the North Country/Saint Lawrence Valley closer to the northern periphery of the ridge.

A very gradual day-to-day 'cooling' is then expected for the Fri-Sun timeframe as successive shortwaves traversing eastward through central and eastern Canada slowly suppress the ridge to the south, leaving a quasi-zonal flow in place across the CONUS by the end of the period. That said, still want to emphasize that conditions are still going to remain very warm to hot with elevated humidity levels. In terms of temperatures, upper 80s/low 90s Friday will slowly trend downward to the mid and upper 80s by the end of the weekend, with the highest elevations several degrees cooler respectively on any given day. Heat index values will reach the low to mid 90s for all of the lower terrain Friday afternoon, upper 80s to low 90s Saturday afternoon, and mid 80s to near 90 by Sunday.

In terms of precipitation, there will be some increase in convection potential as we close out the work week and head into next weekend.
This will be owed to mainly two things: Upper level disturbances riding the northern periphery of the upper ridge passing closer and closer to the area as the center of the ridge slowly sags further south through the period, while a surface boundary also sags south toward the region from Canada. Areas that do receive some showers/storms, will enjoy some relief, however any reprieve will only be temporary.

VFR flight conditions expected through the end of the TAF cycle.


Monday night...VFR.
Tuesday through Friday...VFR, but a slight chance for afternoon thunderstorms inland from the lakes.

Winds will be light Monday through much of next week as high pressure anchors over the Ohio Valley and New England.
