THE SYNOPTIC PATTERN FEATURES AN OMEGA BLOCK ACROSS THE CONUS
WITH TROUGHING IN THE NORTHERN/CENTRAL PLAINS AND ACROSS THE
EAST COAST WITH A RIDGE AXIS FROM THE GREAT LAKES THROUGH THE
MISSISSIPPI VALLEY. THE OMEGA BLOCK BREAKS DOWN LATER THIS WEEK
WITH A LOW AMPLITUDE PATTERN DEVELOPING BY MID TO LATE WEEK.
MOSTLY DRY WEATHER IS EXPECTED THROUGH AT LEAST WEDNESDAY. A FEW
SHOWERS OR STORMS CANNOT BE COMPLETELY RULED OUT TODAY ACROSS
FAR SOUTHEAST MISSOURI. KEPT THE LOW END POPS (< 30%) FOR THIS
AREA THROUGH THE AFTERNOON. TEMPERATURES WILL CONTINUE TO BE
ABOVE NORMAL THIS WEEK WITH HIGHS INTO THE LOW TO MID 90S FOR
MOST LOCATIONS. WE STILL LOOK TO LUCK OUT ON THE LOWER DEWPOINTS
AND SUBSEQUENT LOW HEAT INDICES.
THE NEXT CHANCE OF SHOWERS AND STORMS ARRIVE LATE IN THE WEEK
AND WEEKEND ASSOCIATED WITH AN UPPER LEVEL TROUGH ACROSS THE
NORTHERN PLAINS. CHANCES OF SHOWERS AND STORMS INCREASE ACROSS
PORTIONS OF SOUTHEAST MISSOURI AS EARLY AS FRIDAY MORNING WITH
