BIG TEMPERATURE CHANGES ARE COMING! It has been a record setting weekend across our area, with highs nearing the triple digit mark. Yesterday Tuscaloosa topped out at 99°, breaking the previous record of 97° set back in 1961. Anniston also set a record high at 97°, which broke the record of 96° set way back in 1931. We could shatter more records this afternoon; however, this could possibly be our last day of extreme heat for 2016.
A southerly flow has developed in advance of an approaching cold front and this has fueled some isolated showers this afternoon. A cold front will enter the area tomorrow and bring a better chance for scattered showers and storms, especially in the afternoon and evening. After the front passes, some model data suggest we could see some post-frontal shower activity early Tuesday morning, although the coverage will remain very spotty. A cooler-dry northerly flow will take over behind the front, with clearing by Tuesday afternoon.
COOLER AIR SETTLES IN: Cooler air is expected to spill into the region on Wednesday, as an upper air trough develops over the Eastern United States. We will have high temperatures tumbling into the 70s for mid to late week, with overnight lows in the chilly low 50s. A few outlying areas over the Tennessee Valley could see lows nearing the 48° early Thursday and Friday! So it’s time to start breaking out the long sleeves for chilly mornings. It’s going to remain very dry through the rest of the week, with lots of sunshine each day. I will have more specifics on the cooler weather beginning at 9PM.
TROPICS: We continue to track post-tropical cyclone Karl over the Atlantic. This system continues to track northward over the cooler north Atlantic. We need to keep our eye on a new disturbance about 1500 miles east-southeast of the Windward Islands. This system has about a 90% chance of developing over the next five days and it’s expected to track west and impact the Caribbean.
