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.
Morning GOES 1km visible image shows smkoy smudge from NW-SE from St. Cloud through Twin Cities area.
Next rain Friday:
It appears our next shot of rain will roll in Friday. Expect a chance of showers and storms to move into northwest Minnesota tonight and overspread the state Friday.
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!
