Red Flag Day

Red Flags are posted in an area when there is a high danger for fire.  High winds and low humidities had everything to do with this.  Our prairie sits within a highly residential area. If we were out in the middle of nowhere, I think we'd be rocking and rolling.  With the winds and humidities burns would more than likely get out of control.  They move very fast, and the possibility of spot fires elsewhere on site are great.

Forecast:
Backing winds are forecasted to lift northward Wednesday night into Thursday morning for our region.  The south winds will turn to southeast.  This is the wind direction we need.  However with these backing winds could be followed by precip, as any low pressure system is associated with.  This isn't a conventional low pressure system though.  We have a window in the morning to get the burn done.  Rh looks to be in the 50s by 9am with the right wind direction, and still awaiting the mixing height/ventilation forecast tomorrow for thurs.

NOAA quote from today:
"UNREAL. THAT IS ABOUT THE ONLY (AFD FRIENDLY) WORD THAT COMES TO MIND WHEN TRYING TO WRAP MY MIND AROUND THE CURRENT WARM SPELL. IT IS REMARKABLE ENOUGH TO WATCH LONG STANDING ALL TIME RECORD TEMPS BE THREATENED...BUT THE TOTAL SCOPE (DURATION AND INTENSITY) OF THIS WARM SPELL ISSOMETHING THAT HAS HISTORIC AND UNLIKELY TO BE MATCHED IN OUR LIFE TIME."








Everyone knows how warm its been.  Chicago has broken every temp record for 11 days straight!  This also leads into another variable with the burn.  With everything greening up, this creates more of a smoke issue.  A burn shouldn't hurt the natives too much due to an established root system they carry.  Cool season grasses do not carry this trait, and they will suffer which is good.  It all depends on your burn objectives.
