.DISCUSSION...
HIGH PRESSURE OVER EASTERN MONTANA WILL MOVE INTO THE DAKOTAS
ALLOWING UPSLOPE FLOW TO DECREASE. THIS WILL ALLOW SKIES TO CLEAR
AND BECOME MOSTLY SUNNY WITH TEMPERATURES RISING INTO THE LOWER 50S.
THE AIRMASS WILL BE SLOW TO DRY OUT TODAY SO MINIMUM HUMIDITY WILL
BE NEAR 40 PERCENT THIS AFTERNOON. SURFACE LOW PRESSURE MOVING
INTO ALBERTA WILL ALLOW WINDS TO BE SOUTHERLY TODAY AND TONIGHT
BUT SPEEDS WILL REMAIN LIGHT. THURSDAY WILL BE WARMER WITH WINDS
BECOMING WESTERLY AND JUST A BIT STRONGER. BORSUM
