WEST PALM BEACH, Fla. — We have some big changes heading this way over the next couple of days.

Up to this point, we've seen a few cold fronts pass through South Florida. Most of them knock the temps down a little bit and drop the humidity back down into the comfort zone. But the front that arrives this week is powerful!

Straight out of Canada, this air mass will likely drop West Palm Beach down into the 40s for overnight lows by the end of the week. The Treasure Coast may see many nights in the 40s. Daytime highs will stay in the low to mid 70s from north to south.

Before this front arrives, we have to get through what will likely be a broken line of showers and downpours Wednesday afternoon. There could even be a rumble or two of thunder or maybe even a quick hitting thunderstorm. This is the remnants of what was once Tropical Storm Sara absorbed within a cold front. Dynamically, there's not a lot left with this system as it moves through south Florida. So, the threat for severe weather is very low!

But some wet weather is likely at some point. Perhaps a bit of of wind too, gusts 25-35 mph.
