BREEZY NORTHWEST WINDS WITH A FEW MID TO HIGH LEVEL CLOUDS WILL
BE FOUND THROUGH THIS EVENING. THESE BREEZY WINDS ARE ALSO
PROVIDING FOR SOME WARMER TEMPERATURES IN THE 50S TODAY.
TONIGHT, SURFACE RIDGE WILL REMAIN IN THE WEST, WHILE NORTHWEST
FLOW REMAINS ALOFT. THE RESULT WILL BE DRY CONDITIONS WITH
DIMINISHING WINDS. IF WINDS CAN DIMINISH AND SKIES CAN CLEAR,
THERE COULD BE SOME PATCHY FOG TONIGHT. THE HIGHER PROBABILITY
FOR THIS TO OCCUR WOULD BE IN WESTERN ND WHERE SOME PATCHY FOG
WAS ADDED INTO THE FORECAST, ALTHOUGH THE OVERALL CHANCES FOR
FOG IS LOW TONIGHT GIVEN DRY CONDITIONS IN PLACE. THE SPACE
WEATHER PREDICTION CENTER HAS A G4 SEVERE GEOMAGNETIC STORM

CLEAR SKIES. COOLER TEMPERATURES WILL ALSO BE FOUND WITH THE

RIDGE MOVES EASTWARD WEDNESDAY NIGHT, INCREASING MID TO HIGH
LEVEL CLOUDS ARE EXPECTED WITH SOUTHWEST AND WARMING FLOW ALOFT.
MAINLY DRY CONDITIONS ARE STILL FORECAST, HOWEVER, INCREASED
