.Discussion...
Dry weather is forecast through Friday under the influence of high
pressure. Winds should gust to around 20 MPH on average this
afternoon. Additional mixing of drier air Thursday will result in
minimum humidities into the 30s and lower 40s, and low level
winds will veer to the east. Similar, if slightly lower, relative
humidities are pictured for Friday, with continued veering wind
toward the southeast.
High pressure and height rises into the weekend will maintain dry
weather and seasonable temperatures.
