.UPDATE...
ISSUED AT 1021 AM CDT SAT APR 25 2015

THE CWA WAS COVERED BY LOW CLOUDS ALONG WITH AREAS OF FOG THIS
MORNING. IT LOOKS LIKE THE FOG WILL DISSIPATE WITH THE CEILING
HEIGHTS INCREASING THROUGH THE DAY WITH MAYBE SOME BREAKS IN THE
CLOUDS EAST. TEMPERATURES SHOULD STILL BE ABLE TO RISE INTO THE
50S AND LOWER 60S BY LATE AFTERNOON. TOOK OUT POPS ACROSS THE WEST
ALSO FOR TODAY.

&&

.SHORT TERM...(TODAY THROUGH MONDAY AFTERNOON)
ISSUED AT 323 AM CDT SAT APR 25 2015

ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL LIKELY
CONTINUE ACROSS THE SOUTHERN CWA THROUGH THE MORNING HOURS AS WEAK
UPPER LEVEL ENERGY WOBBLES AROUND THE NORTHERN PLAINS. DUE TO THE
MOIST EASTERLY FLOW...STRATUS CURRENTLY OVER THE CWA IS LIKELY TO
STICK AROUND THROUGH THE DAY...AND BECAUSE OF THE CLOUD
COVER...TEMPERATURES ARE LIKELY TO BE COOLER...MAINLY IN THE 50S
AND 60S ACROSS THE REGION.

AN UPPER RIDGE THEN DEVELOPS OVER THE REGION...WITH A HIGH
AMPLITUDE LONG WAVE TROUGH SETTING UP FURTHER WEST. THE RESULT
APPEARS TO BE CLEAR AND DRY CONDITIONS ACROSS THE EASTERN
CWA...AND CLOUDY WITH ON AND OFF RAIN SHOWERS POSSIBLE ACROSS THE
WEST. IT ISNT UNTIL MONDAY THAT THE TROUGH BEGINS TO MOVE
EAST...DRAGGING A FRONT ACROSS THE CWA. RAIN CHANCES ARE POSSIBLE
ALONG THE FRONT...WITH BEST CHANCES APPEARING TO BE ACROSS THE
NORTHERN CWA...ALTHOUGH QPF AT THIS POINT LOOKS FAIRLY LIGHT.
TEMPERATURES RISE BACK INTO THE 60S AND 70 FOR SUNDAY AND MONDAY.

.LONG TERM...(MONDAY EVENING THROUGH FRIDAY)
ISSUED AT 323 AM CDT SAT APR 25 2015

AN UPPER TROUGH WILL WORK ITS WAY ACROSS THE REGION MONDAY NIGHT
BRINGING SOME SHOWERS. BY TUESDAY SFC HIGH PRESSURE SETTLES IN AND
AN UPPER RIDGE BEGINS TO SHIFT INTO THE NORTHERN PLAINS. THIS WILL
KEEP THE WEATHER PATTERN MOSTLY DRY THROUGH FRIDAY. ANOTHER LOW
PRESSURE SYSTEM MAY MOVE THROUGH THE DAKOTAS FRIDAY NIGHT AND
SATURDAY. MODELS DIFFER ON THE TIMING AND EXTENT OF THIS SYSTEM
BUT HAVE SOME SLIGHT CHANCE POPS IN THE FORECAST FOR NOW.

TEMPERATURES WILL RISE THROUGH THE PERIOD...ESPECIALLY UNDER THE
UPPER RIDGE. HIGHS MAY TOP OUT NEAR 80 BY THE END OF THE WEEK
DEPENDING ON CLOUD COVER.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 1235 PM CDT SAT APR 25 2015
