OVERALL, THE FLOW ALOFT WILL BE MAINLY FROM THE NW MUCH OF THE
UPCOMING WEEK AS AN UPPER LEVEL RIDGE IS OVER THE WRN US. MON AND
TUE WILL SEE ABOVE NORMAL TEMPS WITH DRY CONDITIONS IN PLACE.
FOR TUE NIGHT, A COLD FRONT WILL MOVE ACROSS THE PLAINS. POSITION
OF AN UPPER LEVEL JET MAY ALLOW FOR A SLIGHT CHC OF SNOW SHOWERS
OVER PORTIONS OF THE PLAINS LATE TUE NIGHT INTO EARLY WED MORNING.
TEMPERATURES WILL BE COOLER ON WED BUT READINGS WILL STILL REMAIN 5
TO 10 DEGREES ABOVE NORMAL.
BY THU INTO FRI THE UPPER LEVEL RIDGE MAY RETROGRADE SLIGHTLY
WESTWARD WITH THE FLOW ALOFT BECOMING MORE NNW. AS A RESULT, A
STRONGER COLD FRONT MAY AFFECT THE AREA LATE THU NIGHT INTO FRI.
CROSS-SECTIONS FROM THE MODELS SHOW VARYING AMOUNTS OF MOISTURE
ASSOCIATED WITH THE FRONT. THE GFS HAS MORE MOISTURE VS THE DRIER
CANADIAN AND ECMWF. THE GFS SOLUTION WOULD BRING A CHC OF LIGHT
SNOW TO THE AREA, LATE THU NIGHT INTO FRI MORNING, WHILE THE
CANADIAN AND ECMWF SOLUTIONS WOULD HAVE BASICALLY DRY CONDITIONS.
TEMPERATURES WILL BE WARMER ON THU AND THEN DROP BACK TO SEASONAL
LEVELS ON FRIDAY.
NEXT WEEKEND LOOKS MAINLY DRY AS THE AREA REMAINS UNDER NW FLOW
ALOFT. TEMPERATURES WILL BE NEAR OR SLIGHTLY ABOVE NORMAL.
