A drastic weather change is on the way. As the week continues, south Florida will experience something rare: a steady surge of brisk air spilling down from the north! The "main batch" of winter-type air will follow a strong cold front crossing late Wednesday. How cold will it get? Nighttime lows will settle back into the 40s (for at least a couple nights) while daytime highs struggle to reach even 60-degrees. Keep in mind, temperatures this season have been exceptionally warm. Further, when we've had a little encounter with cooler conditions, they just haven't lasted very long!
Here's a satellite image which indicates two distinct lines of clouds. The plume of clouds is with a WEAK cold front that extends across central and south Florida. This initial boundary will only create a small drop in temperature (into Wednesday). Then, the second front will be the one that actually brings us the "real chill".
What's unique about this particular weather pattern is that we'll get a "persistent" air flow from the north. This continued connection will make for a lengthy cooling trend... as the cool spell will even hold into next week!
