Relative humidities will most definitely remain critical, with values into the single digits expected. The pressure gradient should keep winds light through Friday, but Saturday there is a chance we could see enhanced winds mix down to the surface from the mid-levels. If this occurs, at minimum it looks that we will see enhanced fire weather concerns, but there is a chance we could be looking at near red flag concerns from sustained winds 15-20 mph. Currently, we`re erring on the low side with winds generally around 6-12 mph from the northwest for the site, but we`ll continue to watch forecast updates tonight and tomorrow to see how models handle the mid-level winds and their influence on the lower levels. .REST OF TONIGHT...
