A STRONG RIDGE OF HIGH PRESSURE DOMINATES THE WESTERN
STATES...BRINGING OUR AREA GENERALLY DRY AND MOSTLY SUNNY
WEATHER. THERE REMAINS A RATHER TIGHT PRESSURE GRADIENT BETWEEN
THIS HIGH PRESSURE AND A LOW PRESSURE IN MANITOBA. THIS IS
RESULTING IN MODERATELY STRONG NORTHWEST WINDS TODAY. SURFACE
PRESSURE GRADIENTS ARE EXPECTED TO BE WEAK TONIGHT THOUGH...SO
WINDS SHOULD QUICKLY DIE OUT BY SUNSET. LOW PRESSURE OVER
MANITOBA MOVES FARTHER EAST MONDAY...RESULTING IN LESS WIND.
