A shift to a northwesterly wind flow in the upper atmosphere is feeding smoke from Canadian forest fires aloft into the skies over Minnesota.

DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY

THROUGH 0102Z July 29, 2010

Central Canada:

The numerous large wildfires of SE Northwest Territories, SW Nunavut,

and N Saskatchewan continue to emit copious amounts of dense smoke.

Dense smoke covers a large portion of N Saskatchewan into W Manitoba, the

NE corner of ND and the northern half of MN. Moderate smoke is connected

to this area over central and northern Saskatchewan over SE NW Territories

and S continental Nunavut into much of western and northern Hudson Bay.

A few other areas of moderate smoke can be seen over N Lake Superior

and NE Ontario as it moves S and SE around the western side of the large

vortex over James Bay and E Quebec.

The best chance for heavy rains appears to be in the southwest half of the state, but the system will have to be monitored.

In the mean time, enjoy a picture postcard Thursday, and watch for a reddish sunset tonight!
