OF THE FORECAST AREA...WITH TEMPERATURES IN THE LOW TO MID 70S MOST

LIKE THIS MORNING...EXPECT SOME PATCHY FOG OVER MUCH OF THE AREA
TONIGHT.

SOME CHANGES ARE COMING FOR THURSDAY.  THE MORNING WILL STILL BE
QUIET WITH THE SURFACE RIDGE SHIFTING OFF TO THE EAST...BUT WILL
ALLOW WINDS TO SWITCH AROUND TO THE SOUTH.  A MID LEVEL WARM AIR
ADVECTION BAND AND A WEAK MID LEVEL SHORTWAVE WILL BRING SHOWERS AND
THUNDERSTORMS TO PARTS OF THE EASTERN DAKOTAS AND WESTERN AND
CENTRAL AND SOUTHERN MINNESOTA DURING THE AFTERNOON...JUST CATCHING
THE SOUTHWEST PORTIONS OF THE FORECAST AREA.  THE WARM AIR ADVECTION
WITH THIS SYSTEM DURING THE DAY WILL STILL BE WEAK ENOUGH THAT HAVE
ONLY PUT HIGHS INTO THE MID AND UPPER 70S.

SURFACE HIGH PRESSURE WILL PROVIDE THE NORTHLAND MOSTLY CLEAR SKIES
FOR WEDNESDAY NIGHT AND THURSDAY. A UPPER LEVEL RIDGE OVER THE
NORTHERN PLAINS WILL SHIFT INTO THE UPPER MIDWEST. THIS WILL PROVIDE
SLIGHTLY WARMER TEMPERATURES FOR THURSDAY COMPARED TO WEDNESDAY.

AN UPPER LEVEL LOW OVER THE PACIFIC NW WEDNESDAY NIGHT WILL LIFT
INTO SOUTHERN ALBERTA AND SOUTHERN SASKATCHEWAN THURSDAY AND
THURSDAY NIGHT. THE ASSOCIATED SURFACE TROUGH OR OCCLUDED
FRONT...WHICH WILL EXTEND TO THE SE INTO THE NORTHERN PLAINS...WILL
APPROACH AND MOVE INTO THE NORTHLAND LATER THIS WEEK. THIS WILL
PROVIDE THE NORTHLAND WITH LOW CHANCES OF SHOWERS AND STORMS FRIDAY
AND SATURDAY. THE UPPER LOW WILL LIKELY MOVE THROUGH THE NORTHLAND
DURING THE LATTER HALF OF THE WEEKEND AND CONTINUE TO PROVIDE LOW
CHANCES OF SHOWERS AND STORMS.

THE MODELS ARE SUGGESTING THAT HIGH PRESSURE WILL MOVE INTO THE
CENTRAL UNITED STATES AND PROVIDE THE NORTHLAND WITH DRY WEATHER FOR
THE EARLY AND MIDDLE OF THE WEEK.
