yoda Posted September 4, 2023 Share Posted September 4, 2023 @MN Transplant morning AFD from LWX mentioned dewpoint mixing I believe in the short term discussion part .NEAR TERM /THROUGH TONIGHT/... Well above average temperatures continue into this morning. Normal morning lows should be in the upper 50s to low 60s this time of year, depending on your exact location, and many areas are still around 70! More of the same is expected today as we saw on Sunday. High pressure to the south and a strong upper ridge will set the stage for a very hot air mass over the region. Winds out of the WNW could again result in significant warming in downslope flow, especially for areas up next to the ridges. Could see many spots make a run at 100 today, but most will see mid-upper 90s. In fact, some spots may even reach record highs today (see climate section below for more details). Humidity will again be manageable, through it will still feel plenty hot. Dew points in the 60s should keep us out of and advisory criteria, but it will certainly be close, and anyone outdoors today should still remember to keep hydrated and take plenty of breaks in the shade/air conditioning. Going into tonight, temperatures may even be a touch warmer overnight than we saw this morning. Some spots could see record warm overnight lows. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... The hottest days of the week look to be on Tuesday and Wednesday. The pattern remains similar, with the ridge aloft strengthening ever so slightly. Temperatures at 850mb warm a degree or so each day Tuesday and Wednesday when compared to Monday, with values anywhere between 20-24 deg C. This, paired with downsloping winds, should yield afternoon high temperatures in the upper 90s to low 100s. Maintaining thoughts on humidity, as the downsloping winds will crash the dew points (perhaps even more than currently forecast). Think we remain below advisory criteria once again on Tuesday, but Wednesday could come very close. Either way, that doesn`t take away the fact that it will be extremely hot during this time period, and you should be taking proper precautions to avoid heat-related illness. Overnight lows remain very warm both nights, with record warmth during the overnight possible once again. 1 Link to comment Share on other sites More sharing options...

Saw a few raindrops in my morning run. Not even a trace though, just made it even more humid. 1 Link to comment Share on other sites More sharing options...
