afternoon. Afternoon humidities today will drop to around 12-15%
with wind gusts up to 20 mph. A warm front on Wednesday will
support more robust moisture transport with a 30-60% chance of
showers and thunderstorms. Stronger storms will be capable of
producing wind gusts in excess of 30-40 mph, brief heavy rain, and
