FORECAST DISCUSSION FOR ROUTINE AFTERNOON FORECAST ISSUANCE

.SHORT TERM...TONIGHT AND MONDAY
ISSUED AT 228 PM CDT SUN APR 26 2015

HIGH PRESSURE WILL CONTINUE TO DOMINATE THE WEATHER PATTERN TONIGHT
AND MONDAY. CLOUDY COVER ACROSS ONTARIO IS EXPECTED TO ROTATE
SOUTHWEST INTO EASTERN WISCONSIN LATER TONIGHT. THE QUESTION IS
HOW FAR WEST AND THE COVERAGE OF CLOUD COVER. DID BUMP UP CLOUD
COVER LATE THIS EVENING AND OVERNIGHT BASED ON MODEL GUIDANCE.

ANY LINGER CLOUDS ACROSS EASTERN WISCONSIN WILL DEPART LATER MONDAY
MORNING WITH SUNNY SKIES EXPECTED MONDAY AFTERNOON. ONLY MINOR CHANGES
MADE TO THE MINIMUM TEMPERATURES TONIGHT AND BUMPED UP MAX TEMPERATURES
A DEGREE OR TWO ON MONDAY.

.LONG TERM...MONDAY NIGHT THROUGH SUNDAY
ISSUED AT 228 PM CDT SUN APR 26 2015

MAINLY QUIET WEATHER IS EXPECTED FOR MUCH OF THE UPCOMING WEEK AS
THE ENSEMBLE MEANS SHOW ABOVE NORMAL HEIGHTS JUST UPSTREAM OVER THE
NORTHERN PLAINS DURING THIS STRETCH.  GUIDANCE HAS BEEN TRENDING
MORE SOUTHWESTERLY TOWARDS THE ECMWF AND GEM SOLUTIONS...WITH THE
TRACK OF THE DIGGING SHORTWAVE FOR MIDWEEK...BUT IMPACTS LOOK EVEN
LOWER THAN YESTERDAY.  WILL RELY ON THE LATTER GUIDANCE FOR THIS
SYSTEM.  MODELS ALSO CONTINUE TO SHOW WEAK SHORTWAVES MOVING OVER
TOP THE RIDGE LATE IN THE WEEK ALBEIT WITH TIMING DIFFERENCES.
THEREFORE...THE ALLBLEND WILL WORK FOR LATER PERIODS.

MONDAY NIGHT THROUGH WEDNESDAY...MOSTLY CLEAR AND QUIET ON MONDAY
NIGHT THANKS TO HIGH PRESSURE AT THE SURFACE AND RIDGING ALOFT.
WILL TREND COLDER FOR TEMPS.  THEN A WEAK AND SHEARED SHORTWAVE WILL
BE DROPPING SOUTHEAST OVER THE NORTHERN MISSISSIPPI VALLEY ON
TUESDAY.  MID AND HIGH CLOUDS COULD MOVE INTO CENTRAL WISCONSIN BUT
STILL LOOKING AT A DRY DAY.  THE SHORTWAVE WILL DIVE IN A MORE
SOUTHERLY DIRECTION ON TUESDAY NIGHT AND BYPASS THE REGION.
ANY MID AND HIGH CLOUDS WILL GENERALLY DRY UP AS HIGH PRESSURE
BUILDS BACK INTO THE REGION.  ANOTHER SHORTWAVE WILL PASS NORTH OF
THE REGION ON WEDNESDAY LEAVING DRY AND SEASONABLE CONDITIONS IN
PLACE.

REST OF THE FORECAST...HIGH PRESSURE WILL BE IN PLACE THURSDAY INTO
THURSDAY NIGHT WHICH WILL CONTINUE THE SEASONABLE AND DRY
CONDITIONS.  THE NEXT SHORTWAVE ENERGY WILL BE MOVING OVER TOP THE
MID-LEVEL RIDGE ON FRIDAY.  THIS WAVE WILL BRING THE NEXT CHANCE OF
RAIN TO THE REGION...BUT WITH NO GULF MOISTURE...ANY RAINFALL WILL
LIKELY BE ON THE LIGHT SIDE.  TEMPS ARE PROJECTED TO BE WARMER
BEHIND THE SYSTEM FOR SATURDAY BEFORE GUIDANCE BRINGS IN LOW
PRESSURE FOR SUNDAY.
