While heat is the main story this weekend, with a heat advisory in effect for Tallahassee and heat indices above 100 across the region, tomorrow is the beginning of a long stretch of wet weather. Pack an umbrella if traveling and keep phone alerts on, as the risk of flash flooding begins tomorrow and continues through the week.
A surface low and cold front are currently just north of the Gulf states. A trough in the jet stream will gently push the system southward.
Once the front gets here, it’s going to hang around for a while as a stationary boundary. Down at 850 mb, we’ll have a persistent southwesterly flow off the Gulf, pulling in a ton of available moisture.
When you combine a stalled front with a surge of tropical moisture, that’s a notorious setup for some pretty impressive rainfall totals. On top of that, another plume of deep moisture is expected to move into the region later this week. That could bring localized flash flooding along with river flooding.
We’re expecting scattered showers and thunderstorms capable of dumping a lot of rain in a short amount of time, with some storms potentially training over the same locations for several hours…
