Labor Day Weekend Forecast
High pressure overhead on Friday will shift to the southeast this weekend, opening the region to a surge of hot and increasingly humid weather.
The changing temperatures will be the main weather story through the Labor Day weekend.
Friday will have near-average temperatures despite a chilly start to the day. Look for afternoon highs to rise to the mid 70s under mostly sunny skies. Humidity values will remain low with dewpoints in the 50s, and winds will be nearly calm throughout the day.
Saturday will start off with low and mid 50s, which is close to average for early September. Afternoon highs will rise above average, however, topping out mostly in the low 80s. Dewpoints will again remain in the 50s.
There will be some extra cloud cover on Saturday thanks to a weak system passing through the region. Many of the clouds will be thin and allow at least some sunshine through. A very isolated light shower cannot be ruled out, mostly during the evening hours.
Temperatures will continue to rise on Sunday, starting with morning lows mostly between 60-65 degrees. Afternoon highs will push into the mid 80s with dewpoints rising to the low and mid 60s.
Sunday’s skies will be mostly sunny, though a few stray fair-weather clouds will be possible.
There will be another very small chance for a stray shower early Monday morning before the rest of the day turns sunny with a few clouds.
Temperatures will rise several more degrees, with highs in the upper 80s to near 90 degrees on Monday. Dewpoints will mostly remain in the mid 60s.
Winds will remain on the light side throughout the weekend. Saturday will have south and southwest winds at just over 5 mph, while Sunday will have south winds early turning to the northwest late. Wind speeds will be around 5 mph. Monday’s winds will be light and variable.
Heat Continues Next Week
There will be very little change in the weather pattern until late next week.
Tuesday and Wednesday will have the best shots at seeing widespread temperatures near or above 90 degrees.
Both days will start with morning lows in the mid 60s and will have persistent sunshine throughout the day. Winds will remain light and variable.
Dewpoints will also rise further and it will become quite humid. Expect dewpoints in the upper 60s to near 70, which will push heat index values toward the mid or even upper 90s.
Thursday could very well equal Tuesday and Wednesday’s heat, but the uncertainty is a bit higher. There is a small chance for a few late-day showers and storms, which could help prevent temperatures from getting quite as hot.
Right now, I am calling for upper 80s to near 90 degrees on Thursday with mid and upper 60s dewpoints.
The chances for scattered showers and storms will increase on Friday and Saturday, but there is still quite a bit of uncertainty in how the rain chances play out.
What is more certain is that the heat will start to retreat. Temperatures will probably be back in the 70s as early as Sunday, and the following week looks to have near-average temperatures in the 70s.
Given the quiet weather and the holiday weekend, my next blog post will come on Tuesday morning. You can always get the updated forecast for your location using the zip-code forecast, which will be continuously updated each day.
Have a happy Labor Day weekend!
