.DISCUSSION...Temperatures will warm as high as 5-15 degrees 
above normal this weekend with high pressure building overhead.

east/southeasterly nocturnal winds are possible Saturday and 
Sunday as well, especially south of I-70. Looking ahead to next 
week, light winds and an uptick in moisture will keep critical 
fire weather conditions in check. However, unseasonably warm and 
dry conditions persist, especially along and north of I-70.
