QUASI-ZONAL FLOW CONTINUES ACROSS THE STATE. AN UPPER LEVEL WAVE
MOVES THROUGH THE AREA INTO EASTERN NORTH DAKOTA. HIGH
TEMPERATURES ARE FORECAST TO WARM INTO THE 40S TO LOWER 50S
AHEAD OF A WEAK COLD FRONT. PATCHY FOG CONTINUES ACROSS THE
NORTHWEST THIS AFTERNOON SLOWLY BURNING OFF, AND COULD RETURN
TONIGHT ACROSS MUCH OF THE SOUTHWEST. OVERNIGHT LOW TEMPERATURES
ARE FORECAST TO DROP DOWN INTO THE 20S TO 30S. HIGH
TEMPERATURES TOMORROW ARE FORECAST TO BE ON THE COOLER SIDE IN
THE UPPER 30S TO MID 40S AS A COLD FRONT MOVES THROUGH THE
REGION TONIGHT. SURFACE HIGH PRESSURE WILL MOVE THROUGH THE
REGION TOMORROW LEADING TO CLEARING SKIES AND LIGHT WINDS.
AN UPPER LEVEL RIDGE IS FORECAST TO AMPLIFY AND PROGRESS ACROSS
THE NORTHERN ROCKIES INTO THE NORTHERN PLAINS THURSDAY INTO
FRIDAY. THIS WILL PLACE THE NORTHERN PLAINS IN NORTHWESTERLY
FLOW ALOFT. AS A RESULT, QUIET CONDITIONS WILL PERSIST INTO THE
WEEKEND. HIGH TEMPERATURES ARE FORECAST TO REMAIN IN THE 40S TO
50S THROUGH THE WEEKEND. THERE ARE NO STRONG WAVES FORECAST TO
MOVE THROUGH THE REGION THIS WEEKEND, RESULTING IN DRY
CONDITIONS. FORECAST MODELS ARE PICKING UP ON A POTENTIAL SYSTEM
LATER NEXT WEEK BRINGING IN A COLDER AIR LEADING TO BELOW
NORMAL TEMPERATURES. HOWEVER, THERE ARE SOME HINTS THAT A COLDER
AIRMASS MIGHT NOT BE AS STRONG. AS FOR PRECIPITATION THERE IS A
LOT OF UNCERTAINTY, THE ENSEMBLES ARE PRETTY CONSISTENT ON A
CLIPPER SYSTEM REMAINING NORTH IN CANADA THE MIDDLE OF NEXT
WEEK. THIS SYSTEM WILL DROP THE AFOREMENTIONED COLDER AIRMASS
INTO THE REGION.
