HIGH PRESSURE OVER THE DAKOTAS WILL SHIFT EASTWARD ON THURSDAY
ALLOWING WARMER AIR TO RETURN TO THE BURN SITE. COOL MORNING
TEMPERATURES WILL CAUSE THE WARMUP TO BE SLOW WITH MAXIMUM
TEMPERATURES NOT BEING REACHED UNTIL 1500. DEVELOPING LOW PRESSURE
OVER ALBERTA WILL TURN WINDS SOUTHERLY AND SPEEDS WILL BE IN THE
12 TO 16 MPH RANGE AND STEADY. A WEAK UPPER LEVEL RIDGE WILL MOVE
OVER THE BURN SITE WHICH WILL LIMIT MIXING HEIGHTS A BIT BUT THEY
WILL STILL REACH 5000 FEET ABOVE GROUND LEVEL. HUMIDITY MINIMUMS
SHOULD STAY AROUND 30 PERCENT. FRIDAY A SLOW MOVING AND WEAK COLD
FRONT WILL REACH THE BURN SITE AROUND MIDDAY AND STALL ITS
MOVEMENT. THIS WILL KEEP WARM TEMPERATURES OVER THE BURN SITE WITH
