.DISCUSSION...

A cold front passes over the fire site this afternoon through 1700
LT. Expect increasing sky cover to linger into the ignition time
period before clearing occurs for the rest of the evening. An isolated
rain showers cannot be ruled out to create sprinkles at the fire site
through 1600 LT today. Lofted smoke from Canadian wildfires may obscure
the mid to late evening skies though. A wind shift from present
southwesterly to westerly occurs over the next hour or two and then
finally to northwesterly by ignition time. Northwest winds prevail
through the forecast time period of 2100 LT.
