FIRST ALERT: Above average temperatures continue as we head into Fall

BIRMINGHAM, Ala. (WBRC) - No significant changes to our weather pattern are expected as we begin the Official Last Weekend Of Summer. A strong ridge of high pressure remains centered along the East Coast and the moisture content of the air over the Southeast is still very limited so the rain-free conditions will remain through the weekend with mostly sunny conditions likely to continue as well. Afternoon temperatures will again be above average, around 90 in most areas with comfortable overnight lows near 65 again this evening.

The sinking, dry air will continue to limit cloud growth and provide rain-free conditions tomorrow and with the continued southeasterly wind flow temperatures, while above average for this time of year, will remain relatively moderate through the end of the weekend. The area of high pressure will begin to weaken somewhat by Monday allowing a cold front to sink south, approaching the Tennessee Valley during the late afternoon but as our wind flow remain easterly no real increase in moisture is expected although dew points will rise somewhat allowing for greater humidity. Still, any rain which does occur associated with the approaching cold front will likely be limited to Northwest Alabama. With an eventual wind shift ahead of the front temperatures will begin a gradual rise each afternoon and this trend will continue through the end of the work week.

As the high pressure area continues to weaken the cold front will continue sinking south and this could allow for the development of a few more showers during the mid-week period but again these rain areas are expected to be isolated at best. Then, another ridge of high pressure will begin building strength in the wake of the frontal passage which, when combined with the extremely dry soil conditions, could drive temperatures to near record levels by the end of the week. At any rate temperatures will remain above average with below normal rainfall through at least Friday. We’re continuing to Track The Tropics which, while active, show no signs of approaching out Gulf Coast to bring drought relief to the region. If you are heading to the beach, be aware of high rip current risks through at least Monday and take note of the purple warning flags indicating the presence of jellyfish along the Alabama Gulf Coast. Finally, Fall arrives at 2:50 Central Daylight Time Monday morning. It won’t feel much like Autumn but at that time the sun will be directly over The Equator. Happy Last Weekend Of Summer!
