Technical discussion: Another hot one, but big changes are coming soon!

HARTFORD, CT (WFSB) -

Good Wednesday evening!

***An AIR QUALITY ALERT remains in effect for Hartford, Tolland, Windham, Southern Fairfield, New Haven, Middlesex, and New London Counties until 9:00 pm this evening***

For the 12th time this year, the mercury hit the 90 degree mark at Windsor Locks. The high temperature as of 4:00 this afternoon was at least 91 degrees. By this time last year, we had 19 days with a high of at least 90 degrees, but there were none in August! Very interesting when you consider July 2013 was the all-time hottest month on record!

A cold front will pass through the state this evening with scattered showers and thunderstorms. Some thunderstorms could pack a pretty good punch with heavy downpours and vivid lightning, but that will be more the exception than the rule. The front will bring an end to our recent spell of hot weather. In fact, we'll notice a difference overnight as the air begins to dry out. The temperature will dip into the range of 55 to 65 degrees by morning.

Tomorrow will be a very pleasant late August Day! Hurricane Cristobal will accelerate out to sea far to the east of New England and high pressure will head our way from the Great Lakes Region. That means we can expect mostly sunny skies, a nice northwesterly breeze, low humidity, and comfortable temperatures. Afternoon highs will range from the mid 70s in the Litchfield Hills to the low 80s elsewhere.

With clear skies and diminishing winds, the mercury will dip into the 40s and 50s Thursday night. Great sleeping weather! Friday will be another ideal day for outdoor activities with mostly sunny skies and highs in the mid to upper 70s! That is actually a little cooler than normal for late August. The normal, or average, high for August 29th is 81 degrees. If you're heading to Rentschler Field to watch UConn take on BYU for the season opener, you can look forward to very comfortable conditions. The temperature should be close to 72 degrees for the 7:00 pm kickoff.

Warm, humid air will return in a big way over the Labor Day weekend. Saturday will be comfortable with highs in the upper 70s and low 80s. The humidity will remain low and a nice southerly breeze will develop in the afternoon as high pressure moves offshore. However, we'll be feeling the warmth and humidity of summer again both Sunday and Monday. Temperatures will rise well into the 80s to possibly near 90 degrees, and dew point readings could reach 70 degrees, if not higher. While the weekend will not be a washout, we will have to be on the lookout for showers and thunderstorms during the afternoon hours both Sunday and Monday as a cold front settles into New England. Some of these storms could be on the strong side and they will be capable of producing torrential downpours since there will be so much available moisture in the air.

As I mentioned above, Hurricane Cristobal will move away from the New England Coast tomorrow. However, boaters should be aware of the large swells over the open ocean waters and swimmers need to be aware of dangerous rip currents. A High Surf Advisory has been posted for ocean facing beaches from Rhode Island to Cape Cod. This includes Martha's Vineyard and Nantucket. Be careful!

Enjoy the rest of your week!
