AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
243 PM CDT SUN APR 19 2015

FORECAST DISCUSSION FOR ROUTINE AFTERNOON FORECAST ISSUANCE

.SHORT TERM...TONIGHT AND MONDAY
ISSUED AT 243 PM CDT SUN APR 19 2015

WEATHER PATTERN BECOMES MORE ACTIVE STARTING TONIGHT...WITH THE
FIRST CHANCE OF WIDESPREAD RAIN ARRIVING THIS EVENING AND
CONTINUING MONDAY.

CURRENT SFC ANALYSIS SHOWED A DEEPENING LOW PRESSURE SPINNING IN
SOUTHERN ILLINOIS AND SLOWLY DRIFTING NORTH. RAIN BECAME MORE
WIDESPREAD AS THE LOW DRIFTED NORTH...WITH OBS OCCASIONALLY
SHOWING MODERATE TO HEAVY RAIN IN IL AND IN. MEANWHILE...WATER
VAPOR IMAGERY SHOWED ANOTHER DISTURBANCE SHIFTING INTO THE NORTHERN
JET STREAM...WITH A NOTED STRONGER AREA OF FORCING ASSOCIATED WITH
IT ON MESOANALYSIS. THE REFLECTION OF THIS WAS SEEN AT THE SFC
WITH A DEVELOPING LOW AND TRAILING COLD FRONT OVER NE MINNESOTA. HOW
ALL THESE FEATURES INTERACT AS THEY MERGE AND SHIFT THROUGH THE
GREAT LAKES REGION WILL DETERMINE HOW PRECIP TREND PAN OUT TONIGHT.

THROUGH THIS EVENING...TODAYS PRECIP WAS SCATTERED AT BEST AND
EASTERN WISCONSIN EVEN CLEARED OUT AND WARMED UP THROUGH THE
AFTERNOON. GIVEN THE DRIER TREND TODAY...SLOWED DOWN PRECIP
ARRIVAL THIS EVENING. BETTER LIFT DOESNT REALLY OVERTAKE THE CWA
UNTIL AFTER 03Z MONDAY...SO WOULDNT BE SURPRISED IF MANY LOCATIONS
MAKE IT UNTIL SUNSET WITHOUT SEEING MUCH IF ANYTHING IN THE WAY OF
RAINFALL.

TONIGHT AND MONDAY...THE LOW PRESSURE SYSTEM IN IL WILL SHIFT
NORTH AND EAST THROUGH THE NIGHT TOWARDS LOWER MICHIGAN.
MEANWHILE...THE DISTURBANCE OVER MINNESOTA WILL SWING EAST AND
STRENGTHEN AS IT INTERACTS WITH BETTER FORCING. THE TWO SYSTEM
WILL INTERACT AND WIDESPREAD PRECIP IS EXPECTED. INTRODUCED HIGHER
END POPS AFTER 06Z MONDAY AS THE STRONGER FORCING SHIFTS OVER
NORTHEAST WISCONSIN. COULDNT ADD MUCH DETAIL FROM THERE...AS
MODELS DIFFER ON HOW THESE WEATHER FEATURES INTERACT AND WHERE THE
BETTER FORCING WILL BE. LEANED TOWARDS A SOLUTION THAT SHOWED THE
BETTER LIFT AND HIGHER QPF IN CENTRAL AND EASTERN WISCONSIN...BUT
CERTAINLY NOT THE ONLY SOLUTION. HEAVIEST RAINFALL SHOULD BE
BETWEEN MIDNIGHT AND EARLY MONDAY MORNING.

LATEST MODELS HAVE TRENDED TOWARDS A STRONGER LOW IN LOWER
MICHIGAN MONDAY MORNING WITH A MORE EASTERLY TRACK THROUGH MONDAY.
THIS WOULD RESULT IN PRECIP TAKING LONGER TO EXIT THE AREA. IN
ADDITION...A COLD FRONT WILL SWING THROUGH THE STATE THROUGH
MONDAY MORNING AND GIVE ANY LINGERING RAINFALL A QUICK SHOT OF
EXTRA LIFT. INCREASED POPS MONDAY MORNING AND SLOWED THE EXIT OF
RAINFALL MONDAY AFTERNOON TO MIRROR THESE TRENDS. COLDER AIR WILL
FILTER IN BEHIND THE FRONT MONDAY AFTERNOON...AND WILL USHER OUT
THE NICE SPRING WEATHER WE HAVE SEEN THIS PAST WEEK. BELOW NORMAL
TEMPS WILL BE REINTRODUCED STARTING MONDAY AND WONT DO ANYWHERE
QUICKLY. WINDS WILL SHIFT NORTHEAST AND INCREASE MONDAY
AFTERNOON...MAKING IT FEEL A BIT COOLER THAN ACTUAL HIGH TEMPS
MONDAY.

.LONG TERM...MONDAY NIGHT THROUGH SUNDAY
ISSUED AT 243 PM CDT SUN APR 19 2015

COOLER THAN NORMAL WEATHER WILL PREVAIL THIS WEEK AS
AN UPPER LOW SITS OVER THE NORTHERN LAKES. THE UPPER LOW WILL BE
CLOSEST TO NORTHERN WISCONSIN MONDAY NIGHT AND TUESDAY AND SHOULD
HAVE ENOUGH UPPER DYNAMICS TO PRODUCE SNOW AND RAIN SHOWERS OVER
ALL OF THE AREA TUESDAY. SHOULD BE COLD ENOUGH FOR SNOW SHOWERS IN
THE NORTH AND EITHER RAIN OR SNOW SHOWERS IN THE SOUTH. INCREASINGLY
DRIER WEATHER SHOULD FOLLOW FOR THE MIDDLE AND END OF THE WEEK
THOUGH THERE STILL COULD BE SCATTERED SNOW OR RAIN SHOWERS WEDNESDAY.
LAKE EFFECT POTENTIAL IS SMALL MONDAY NIGHT THROUGH TUESDAY NIGHT
DUE TO UNFAVORABLE WIND DIRECTION. WINDS AND INSTABILITY ARE MORE
FAVORABLE WEDNESDAY AND WEDNESDAY NIGHT THOUGH DRIER AIR IS ARRIVING
FROM THE NORTH AS WELL. SO DO NOT EXPECT MUCH IN THE WAY OF LAKE
EFFECT SNOW.
&&

.AVIATION...FOR 18Z TAF ISSUANCE
ISSUED AT 1146 AM CDT SUN APR 19 2015

BROKEN MIDLEVEL CIGS CONTINUE THIS AFTERNOON INTO THE
EVENING...THOUGH VFR CONDITIONS SHOULD PREVAIL. LOW PRESSURE THEN
MOVE ACROSS THE GREAT LAKES REGION TONIGHT AND WILL RESULT IN
AN AREA OF STEADY RAIN OVERNIGHT. PRECIP SHOULD BE SLOWER TO
ARRIVE THAN PREVIOUSLY FORECASTED...WITH RAIN ARRIVING LATE EARLY
TONIGHT THROUGH MIDNIGHT. LOW END IFR CONDITIONS ARE EXPECTED WITH
THIS AREA OF RAIN...WITH LIFR CIGS POSSIBLE AS CURRENT OBS IN
AREA OF INCOMING PRECIP IN IL/IN SHOW SCATTERED CIGS BELOW 500FT.
LIFR CONDITIONS IN CURRENT RAIN NOT WIDESPREAD ENOUGH AND GUIDANCE
WAFFLING ON HOW LOW CIGS WILL GO...SO NOT ENOUGH CONFIDENCE TO ADD
IT TO THE TAFS AT THIS TIME...BUT WILL BE SOMETHING TO MONITOR.
HEAVIEST RAIN AND WORST CONDITIONS WILL LIKELY BE OVER EASTERN TAF
SITES.

RAIN WILL TAPER OFF MONDAY MORNING IN NORTH-CENTRAL WISCONSIN
WITH MVFR CIGS POSSIBLE BY THE SECOND HALF OF THE MORNING. LIGHT
RAIN WILL CONTINUE FURTHER EAST WITH IFR CONDITIONS MOST LIKELY
HOLDING TIGHT UNTIL LATER IN THE MORNING. WINDS WILL BACK FROM
SOUTHEAST THIS AFTERNOON...TO NORTH OVERNIGHT...TO NORTHEAST
MONDAY AS A COLD FRONT SWEEPS THROUGH THE STATE.
