A REINFORCING SHORTWAVE TROUGH IS SINKING SOUTH OVER THE
NORTHERN GREAT PLAINS THIS EVENING. THIS FEATURE WITHIN THE
BROADER LONGWAVE TROUGH IS HELPING TO FILTER ADDITIONAL COOL
AND DRY AIR INTO THE REGION. RAIN CHANCES SHOULD CONTINUE TO
MOVE WELL SOUTH AND EAST OUT OF THE REGION TONIGHT. SURFACE HIGH
PRESSURE BUILDS INTO THE AREA BY MORNING, ALLOWING FOR CALM
WINDS. TEMPERATURES ARE LIKELY TO FALL TO NEAR FREEZING ACROSS
MUCH OF THE AREA. THAT BEING SAID, LINGERING MID TO HIGH LEVEL
CLOUDS SHOULD LIMIT FROST DEVELOPMENT FOR MOST AREAS OUTSIDE OF
AREAS NEAR THE SOUTH DAKOTA BORDER. THE COOLER TEMPERATURES
CONTINUE INTO WEDNESDAY AFTERNOON WITH ANOTHER DAY OF
TEMPERATURES IN THE 50S ACROSS THE AREA. ON THE BRIGHT SIDE,
CLOUD COVER SHOULD GRADUALLY DECREASE WITH PEAKS OF SUN BY THE
AFTERNOON. CLEAR SKIES WILL ALLOW TEMPERATURES TO FALL INTO THE
30S ONCE AGAIN THURSDAY MORNING, BUT AN INCREASING SOUTHWEST
WIND SHOULD KEEP FROST AT BAY FOR MOST. PATCHY FOG IN LOW-LYING
AREAS THAT ARE SHELTERED FROM THE WIND MAY STILL BE POSSIBLE.
TEMPERATURES ARE FORECAST TO WARM THROUGH THE END OF THE WORK
WEEK AS MODEST UPPER-LEVEL RIDGING TAKES OVER. TEMPERATURES RISE
INTO THE LOWER 70S ON THURSDAY BEFORE APPROACHING 80 BY FRIDAY.
IT SHOULD BE DRY FOR MUCH OF THE REMAINDER OF THE WORK WEEK,
BUT A WEAK DISTURBANCE DURING THE MORNING ON FRIDAY MAY BE
ENOUGH TO SQUEEZE OUT A LOW (10-30%) CHANCE OF SHOWERS. OUR NEXT
GOOD CHANCE OF RAIN DOESN'T TAKE SHAPE UNTIL THE WEEKEND.
SATURDAY INTO SUNDAY SEES AN AREA OF LOW PRESSURE TAKE SHAPE
SOUTH OF THE AREA AS A SHORTWAVE TROUGH MOVES OUT INTO THE GREAT
PLAINS. WE ARE LIKELY TO BE ON THE NORTHERN EDGE OF THE BETTER
MOISTURE. THAT BEING SAID, SHOWER AND THUNDERSTORM (30-60%)
CHANCES ARE ANTICIPATED FOR MUCH OF THE AREA. THE BEST CHANCE OF
MEASURABLE PRECIPITATION WILL BE ACROSS SOUTHEAST NEBRASKA AND
SOUTHWEST IOWA, CLOSER TO THE DEVELOPING LOW PRESSURE SYSTEM. A
COOL-DOWN ARRIVES BEHIND THIS SYSTEM ON SUNDAY BEFORE
TEMPERATURES BEGIN TO INCREASE AGAIN EARLY NEXT WEEK.
