CURRENTLY THERE IS QUASI-ZONAL FLOW ACROSS NORTH DAKOTA AT THE
BOTTOM OF A LARGE TROUGH. MOVING ON SHORE IN THE PACIFIC
NORTHWEST, IS A LARGE RIDGE. AT THE SURFACE A STRONG HIGH
PRESSURE CENTER, LOCATED IN EASTERN MONTANA, IS INFLUENCING THE
NORTHERN PLAINS. TEMPERATURES ARE CURRENTLY FALLING INTO THE 20S
ACROSS THE STATE AS THE SURFACE HIGH PRESSURE IS CALMING WINDS
AND NOT ALLOWING A BLANKET OF CLOUDS TO KEEP IN THE RADIATIONAL
HEATING. THE LOWEST TEMPERATURES ARE OCCURRING IN FAR
NORTHWESTERN NORTH DAKOTA, BUT FREEZING TEMPERATURES ARE
POSSIBLE ACROSS THE STATE. FOR WESTERN AND CENTRAL NORTH DAKOTA,
A FREEZING WARNING IS ON GOING. IN THE EASTERN THIRD OF THE
STATE A FREEZE ADVISORY IS ONGOING.
TODAY THROUGH FRIDAY MULTIPLE SURFACE HIGH PRESSURES WILL SLIDE
THROUGH THE NORTHERN PLAINS. ALOFT, NORTHWEST FLOW WILL BE
DOMINATE UNTIL WEDNESDAY WHEN A SMALL RIDGE MOVES ACROSS. THIS
WILL ALLOW WEDNESDAY TO BE THE WARMEST DAY OF THE WORK WEEK AS
SLIGHTLY WARMER 850MB TEMPERATURES MOVE IN. WEDNESDAY WILL ALSO
BE QUITE BREEZY IN THE CENTRAL AND EAST. A TIGHT SURFACE
PRESSURE GRADIENT WILL CREATE SOUTH WINDS TO GUST AROUND 35MPH.
TEMPERATURES WILL GENERALLY REMAIN AROUND THE 60S THROUGH
FRIDAY. FRIDAY NIGHT THE PATTERN ALOFT CHANGES TO SOUTHWEST
FLOW, AS A STRONG LOW AND DIGGING TROUGH EXIST IN THE WESTERN
CONUS. NEXT WEEKEND AS A RESULT COULD BE RAINY AGAIN. THE
