.DISCUSSION...
MAIN FIRE WEATHER CONCERNS FOR THE PRESCRIBED BURN LOCATION TODAY
WILL BE THE GUSTY SOUTH WINDS AND LOW HUMIDITY VALUES. UPPER
LEVEL RIDGE AXIS AND SURFACE HIGH CURRENTLY OVER THE UPPER
MISSISSIPPI VALLEY WILL SHIFT TO THE EAST TODAY AS A TROUGH OF LOW
PRESSURE MOVES INTO THE EASTERN DAKOTAS AND EVENTUALLY NORTHERN
MINNESOTA LATER TONIGHT. THESE TWO FEATURES WILL ALLOW FOR A
TIGHT PRESSURE GRADIENT ACROSS NORTHERN MINNESOTA THIS AFTERNOON
AND PRODUCE SUSTAINED 20 FOOT WINDS 15 TO 20 MPH...WITH GUSTS TO
24 TO 28 MPH. WIND DIRECTION WILL REMAIN FROM THE SOUTH THROUGH
MOST OF THE AFTERNOON. THE STRONGEST WINDS WILL BE THIS AFTERNOON
AND JUST BEFORE SUNSET. AFTER SUNSET THE BOUNDARY LAYER WILL
DECOUPLE AND ALLOW WINDS TO DIMINISH SIGNIFICANTLY. THE OTHER
CONCERN WILL BE THE LOW RH VALUES THIS AFTERNOON. WITH THE CLEAR
SKIES AND VERY DRY AIR IN PLACE...MINIMUM RH VALUES INTO THE
LOWER AND MID 30 PERCENT RANGE CAN BE ANTICIPATED THIS AFTERNOON.
