Precipitation in the northwest quarter of the United States this week has put even more of a damper on the occurrence of wildfires, the execution of prescribed fires, and agricultural burning.

After weeks of warm, dry weather the Black Hills finally received a little precipitation over the last 24 hours. I won’t know the exact amount at my house until the snow in the rain gauge melts, but there was an inch or two of the white stuff on the ground. Today is sunny with a high of 32 predicted, so maybe it will trickle through the tipping bucket this afternoon.

Small amounts of precipitation in southern Saskatchewan may be the reason smoke from that area is no longer immigrating into the United States, as you can see in the two maps below. The first one was the smoke forecast for November 15 and the one after that is for today, November 18.

However, prescribed fires, wildfires, or agricultural burning in Louisiana, Arkansas, and eastern Texas are still producing large quantities of smoke that at times moves north into the midwest.

No rain is predicted until the middle of next week for the areas where wildfires are smoking out the residents in some areas of Tennessee, North Carolina, Georgia, and South Carolina.
