Peak Fog Season
There are high clouds (cirrus), mid-level clouds (altocumulus) and low clouds (stratus). And then there are lazy clouds, stratus that forms at ground level, which we refer to as fog.
September is prime time for fog; the combination of lingering summer moisture and longer nights, which allows the temperature to fall to the dew point, allows invisible water vapor to condense out into visible cloud droplets.
Some of our most vexing challenges: predicting hurricane intensity, forecasting flash floods more than 3 hours in advance, pinpointing where tornadoes will touch down more than 30 minutes into the future, and how thick and stubborn a fog layer will be.
If fog lifts into stratus and doesn't burn off temperatures can be 10-15F cooler than they would be with the sun peeking out.
Any fog this morning should give way to a few "bright intervals" (as meteorologists at the BBC might say). Expect warm sun Friday into Monday with temperatures 10F degrees above average. 80F is not out of the question this weekend. Tuesday thunder ushers cooler air into Minnesota, with highs dipping into the 50s by late week.
Take nothing for granted, especially late September warm fronts.
