TODAY THROUGH SUNDAY...
CLEAR SKIES AND LIGHT WINDS ALLOWED COLD AIR TO PLUNGE INTO THE
REGION OVERNIGHT. MORNING TEMPERATURES PLUMMETED INTO THE UPPER
20S ACROSS PARTS OF NORTHEAST NEBRASKA AND WESTERN IOWA, WITH LOW TO
MID 30S CLOSER TO THE KANSAS AND MISSOURI BORDERS.
WESTERLY WINDS WILL CONTINUE TO ADVECT WARMER AIR DOWN FROM THE HIGH
PLAINS THIS AFTERNOON, AS A SURFACE HIGH SLIPS SOUTH INTO KANSAS. BY
NOON TEMPERATURES HAD REBOUNDED INTO THE UPPER 50S AND LOW 60S.
TONIGHT, A WEAK, DRY COLD FRONT WILL DIP SOUTH THROUGH THE REGION.
WHILE A HANDFUL OF CAMS SHOW SPOTTY SHOWERS WITH THE FRONTAL PASSAGE
OVERNIGHT, FORECAST SOUNDINGS INDICATE A NOTABLE AMOUNT OF LOW LEVEL
DRY AIR THAT WILL LIKELY EAT ANY RAIN BEFORE IT REACHES THE SURFACE.
IF ANYTHING DOES SOMEHOW MAKE IT ALL THE WAY TO THE GROUND, EXPECT
LITTLE MORE THAN TRACE AMOUNTS.
TEMPERATURES WILL BE MORE MILD TONIGHT, DESPITE THE NORTHERLY WIND
SHIFT. OVER NIGHT LOWS ARE ONLY EXPECTED TO FALL INTO THE MID AND
UPPER 40S, GIVING OUR PLANTS A NICE BREAK FROM FREEZING
TEMPERATURES. AN UPPER RIDGE TO OUR WEST WILL BEGIN TO BREAK DOWN,
AS A LOW PRESSURE SYSTEM MOVES INTO THE WEST COAST, AND A NORTHERN
TROUGH BEGINS TO SHIFT SOUTH OUT OF CANADA. PATCHY CLOUD COVER WITH
THE PASSING FRONT COULD INHIBIT OUR WARM-UP POTENTIAL SLIGHTLY
SUNDAY. AFTERNOON HIGHS ARE FORECAST TO REACH THE LOW 70S OVER
NORTHEAST NEBRASKA, AND INTO THE MID 70S NEAR THE NE/KS BORDER, AS
WARM AIR ADVECTION PREVAILS.
MONDAY AND BEYOND...
SLIGHTLY WARMER TEMPERATURES ARE FORECAST FOR MONDAY, WITH HIGHS
REACHING THE MID TO UPPER 70S AND LOW 80S. OFF-AND-ON RAIN CHANCES
(30-60%) WILL RETURN TO THE FORECAST MONDAY THROUGH THURSDAY, AS THE
CUT OFF LOW NEAR CALIFORNIA ATTEMPTS TO PHASE WITH THE LONGWAVE
TROUGH DROPPING INTO THE NATION'S MIDSECTION. A BOUNDARY LYING JUST
TO OUR SOUTH, ACROSS KANSAS AND MISSOURI, WILL BE THE FOCUS POINT
FOR PRECIPITATION. WHILE WIDESPREAD WETTING RAINFALL LOOKS TO REMAIN
JUST SOUTH OF OUR FORECAST AREA, WE WILL STILL HAVE A FEW SHOWERS
DOT THE CWA. THE GREATEST CHANCE FOR PRECIP WITHIN OUR BORDERS
CURRENTLY LOOKS TO BE MONDAY NIGHT INTO TUESDAY ACROSS SOUTHEAST
NEBRASKA AND SOUTHWEST IOWA.
TEMPERATURES WILL LIKELY TAKE A BIT OF A DIP EARLY TO MID WEEK,
DEPENDING ON THE TRACK OF THE MAIN LOW TO OUR NORTH. HIGHS ARE
CURRENTLY EXPECTED TO DROP BACK INTO THE 50S AND 60S TUESDAY AND
WEDNESDAY, WITH AT LEAST SOME POTENTIAL FOR A FROSTY MORNING OR TWO
ACROSS NORTHEAST NEBRASKA WEDNESDAY AND THURSDAY.
TEMPERATURES WILL LIKELY REBOUND THURSDAY AFTERNOON AND BEYOND AS
THE TROUGH SHIFTS EAST AND A RIDGE APPROACHES FROM THE WEST.

NORTHERLY WINDS TO THE AREA.
