SURFACE HIGH PRESSURE CONTINUES TO BUILD AND SLOWLY MOVE
SOUTHEASTWARD HEADING INTO THE MORNING HOURS OF WEDNESDAY. THIS WILL
KEEP SKIES MOSTLY CLEAR TROUGH THE MORNING. THERE IS A MID AND UPPER-
LEVEL CLOSED LOW OVER SOUTH-CENTRAL CANADA WITH TROUGH AXIS
EXTENDING INTO SOUTHERN IOWA. EVENTUALLY THIS WILL PUSH UPPER-LEVEL
CLOUD COVER ACROSS THE REGION TODAY, BUT OVERALL FORCING WOULD BE
WEAK GIVEN THE SURFACE ANTICYCLONE MOVING THROUGH, LEADING TO A DRY
FORECAST FOR WEDNESDAY. HIGH TEMPERATURES TODAY WILL GENERALLY BE IN
THE 60S ACROSS THE REGION.

THURSDAY. MID-LEVEL NORTHERLY FLOW WITH THE PASSING TROUGH AXIS

FOR LIGHT RAIN SHOWER ACTIVITY THURSDAY AFTERNOON AND EVENING,
ESPECIALLY FOR WESTERN AND NORTHERN MISSOURI. RAINFALL AMOUNTS RANGE
FROM JUST A FEW HUNDREDTHS TO JUST A COUPLE OF TENTHS OF AN INCH. A
FEW CAMS DEPICT A FEW HUNDRED J/KG OF MUCAPE MAY BE PRESENT AHEAD OF

OF THUNDER AS THIS PASSES THROUGH.THIS LINE SHOULD PASS THROUGH THE
FORECAST AREA BY MIDNIGHT THURSDAY NIGHT. TEMPERATURES IN THE MID TO
UPPER 30S THURSDAY NIGHT INTO FRIDAY ARE POSSIBLE, WHICH MAY LEAD TO
SOME FROST FOR AREAS NORTH OF HWY. 36.

FRIDAY, AND WILL PUSH ANOTHER SURFACE ANTICYCLONE INTO THE FORECAST
AREA THAT WILL KEEP THIS WEEKEND DRY. TEMPERATURES WILL REMAIN IN
