.DISCUSSION...

High pressure builds in across the area and will keep a cold and dry
air mass over the area, as well as a northerly wind flow over the
coming days with minimum RH values reaching near or below critical
levels at times through Thursday. While wind speeds will generally
remain less than 10 mph and be below red flag criteria, the fire
danger will remain elevated over the next couple of days due to the
