SERVICE.

.DISCUSSION...
MAIN WEATHER CONCERNS FOR THE PRESCRIBED BURN LOCATION TODAY WILL
BE THE LOW HUMIDITY VALUES AND GUSTY SOUTH WINDS. 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.
THESE TWO FEATURES WILL CREATE A TIGHT PRESSURE GRADIENT ACROSS
NORTHERN MINNESOTA THIS AFTERNOON AND PRODUCE 20 FOOT WINDS 15 TO
20 MPH...WITH GUSTS TO 25 MPH. WIND DIRECTION THIS MORNING AND
INTO THE EARLY AFTERNOON WILL REMAIN FROM THE SSE...AND THEN SHIFT
TO THE SOUTH BY THE LATE AFTERNOON AND EARLY EVENING. STRONGEST
WINDS WILL BE THIS AFTERNOON AND JUST BEFORE SUNSET. AFTER SUNSET
THE BOUNDARY LAYER WILL DECOUPLE AND ALLOW WINDS TO DIMINISH TO
AROUND 6 TO 12 MPH. BY MIDNIGHT...THE TROUGH MOVES INTO THE AREA
AND THE WINDS SHIFT TO THE SW...AND EVENTUALLY THE WEST AS THE
TROUGH AXIS MOVES THROUGH EARLY TOMORROW MORNING. THE OTHER
CONCERN WILL BE THE LOW RH VALUES LATER TODAY. WITH THE CLEAR
SKIES AND VERY DRY AIR IN PLACE...EXPECT MINIMUM RH VALUES INTO
THE LOWER 30S THIS AFTERNOON.
