FIRE WEATHER CONCERNS ARE LESS TODAY. WINDS IN MN FCST AREA

AFTERNOON BUT WITH THE SOUTH WIND DEW POINTS INCREASE TODAY SO
RH VALUES STAY 45 TO 50 PERCENT VALUES ON THE LOW END IN NW/WC
MN. WINDS NOT QUITE STRONG ENOUGH TO OVERRIDE THE SIGNIFICANTLY
HIGHER RH VALUES TO NECESSITATE ISSUANCE OF A SPS FOR NEAR
CRITICAL FIRE WEATHER IN MN.

INDICATING AN EXPANDING AREA OF SHOWERS AND POSSIBLY A FEW
T-STORMS INTO THE RRV AND WESTERN MN SATURDAY NIGHT. PATTERN
