Post-Tropical Storm Henriette is forecast to track well to the 
northeast of the state over the next couple of days and turn 
northwestward into the mid-latitudes Monday. Models generally 
agree on lower than normal rainfall through the next week thanks 
to dryness in the mid- levels (300-700 RH < 50%). An upper low 
will likely retrograde along 30N behind Henriette, allowing trades
to weaken a bit. Trades will then gradually increase into next 
weekend as heights rise and the surface pressure gradient 
strengthens.
