Fire weather conditions will again be the focus today. Strong low
level warm advection will overspread the region and combine with
southwesterly winds and clear skies to allow afternoon temps to
warm rapidly. Satellite derived precip water data currently place
a plume of slightly higher moisture over the region and short term

drastically lower. This...along with an a strong west to east
gradient in afternoon temps...raises uncertainty in the afternoon
humidity forecast. Nevertheless expected conditions will support a
heightened fire weather concern and a watch has been posted

Thursday aiding to push temps nearer seasonal normals. A brief

The next chance of precip arrives on Sunday-Sunday night with
increasing agreement on light precip spreading across the area.

level temps will continue to be refined...however any amounts

further south and east. Temperatures quickly moderate with above
normal temperatures likely for the first part of next week.
