AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE, IL
702 AM CDT FRI MAR 25 2016

.SHORT TERM...
336 AM CDT

THROUGH SATURDAY NIGHT...

MAIN FORECAST CONCERNS/CHALLENGES ARE WITH PRECIP CHANCES THIS
WEEKEND...AND THEN SHOWER/THUNDER CHANCES LATE IN THE FORECAST
PERIOD.

RADAR IMAGERY DEPICTING SOME LIGHT RETURNS PUSHING INLAND OVER
NORTHWEST INDIANA...PRIMARILY ACROSS PORTER COUNTY. THESE ISOLATED
SNOW SHOWERS HAVE GENERALLY STAYED ON THE LIGHTER SIDE WITH VIS
RANGING FROM 2 TO 4 MILES. HOWEVER...VIS HAS OCCASIONALLY FALLEN
TO UNDER 2 MILES AT TIMES BUT DONT ANTICIPATE THIS TO CONTINUE
THIS MORNING. CONDITIONS ARE ALREADY NOT OVERLY FAVORABLE FOR
DEVELOPMENT EARLY THIS MORNING...WITH THESE CONDITIONS BECOMING
EVEN LESS FAVORABLE OVER THE NEXT SEVERAL HOURS. FLOW WILL STAY
NORTHERLY THROUGH MID MORNING AND COULD SEE AN ISOLATED LIGHT SNOW
SHOWER TO CONTINUE THROUGH THAT TIME...BEFORE SHIFTING HIGH
PRESSURE HELPS TO END ANY FURTHER DEVELOPMENT. CURRENT STRATUS
OVERHEAD WILL CONTINUE TO SLOWLY DRIFT SOUTHWARD THIS MORNING BUT
WITH ADDITIONAL CLOUDS EXPECTED TO LIKELY MOVE OFF THE LAKE...DID
INCREASE CLOUD COVER OVER NORTHWEST INDIANA THROUGH MID TO LATE
MORNING. SUNNY SKIES ARE THEN EXPECTED TODAY AS HIGH TEMPS RISE
INTO THE 40S FOR MOST LOCATIONS.

ATTENTION THEN SHIFTS TOWARDS ENERGY MOVING THROUGH THE WESTERN
CONUS THIS MORNING. THIS ENERGY WILL MOVE THROUGH THE CENTRAL
PLAINS LATER TODAY AND TONIGHT...WHILE LONGWAVE TROUGH BECOMES
MORE AMPLIFIED. GENERAL MODEL AGREEMENT THIS MORNING WITH TIMING
AND PLACEMENT OF THIS SYSTEM DURING THE DAY SATURDAY...BUT THERE
IS SOME VARIABILITY TO HOW ENERGETIC THIS LEAD WAVE WILL BECOME
THAT EVENTUALLY LIKELY FEEDS INTO FURTHER VARIABILITY WITH THE
EVOLUTION OF THIS SYSTEM. THE BULK OF ANY PRECIP SATURDAY AND EVEN
SATURDAY DOES APPEAR TO STAY TO THE NORTH/NORTHWEST OF THE
CWA...SO DID REDUCE POPS SATURDAY/SATURDAY NIGHT WITH MOST
LOCATIONS LIKELY STAYING ON THE DRY SIDE. THIS LACK OF PRECIP AND
NOW LESS SKY COVER WHILE WAA OCCURS ACROSS THE REGION WILL ALLOW
BETTER WARMING TO OCCUR ON SATURDAY. DID INCREASE TEMPS A COUPLE
OF DEGREES FOR MOST LOCATIONS EXCEPT FOR AREAS NEAR THE LAKE IN
ILLINOIS...WHERE STRONGER ONSHORE FLOW WILL HELP KEEP COOLER
CONDITIONS IN PLACE. ONLY HAVE HIGHS IN THE 50S...BUT COULD SEE
60S BEING REACHED IN SOME LOCATIONS.

.LONG TERM...
336 AM CDT

SUNDAY THROUGH FRIDAY...

ADDITIONAL MID LEVEL ENERGY WILL LIFT THROUGH THE REGION BEHIND
THE EXITING INITIAL WAVE ON SUNDAY. MODEL AGREEMENT NOT THE
GREATEST ON SUNDAY WITH THIS SYSTEM AND IS SHOWING UP WITH THE
SURFACE REFLECTION AND PRECIP SHIELD. A WEAKER AND MORE BROAD
SURFACE LOW STAYING TO THE SOUTH OF THE CWA IS THE PREFERRED
SOLUTION THIS MORNING...BUT SOME GUIDANCE IS SHOWING POTENTIAL FOR
A STRONGER/TIGHTER SURFACE LOW MOVING THROUGH THE CWA. IF THIS
WERE TO OCCUR...MUCH OF THE CWA WOULD OBSERVE MORE WIDESPREAD RAIN
ON SUNDAY WITH EVEN POTENTIAL FOR THUNDER. HOWEVER...THE PREFERRED
SOLUTION FAVORS HIGHEST CHANCES FOR RAIN ACROSS THE SOUTHERN CWA.
HAVE CONTINUED THIS IDEA IN THE GRIDS BUT DID LEAVE CHANCE POPS
ACROSS THE NORTHERN CWA FOR SOME POSSIBLE VARIABILITY WITH THIS
EXPECTED PRECIP SHIELD. THERE IS A SMALL CHANCE FOR A WINTRY MIX
SUNDAY NIGHT...BUT PRECIP WILL LIKELY EXIT PRIOR TO THIS
POSSIBILITY.

DRY AND WARMING CONDITIONS EXPECTED EARLY IN THE WORK WEEK WITH
UPPER LEVEL RIDGING IN PLACE. AS FLOW BECOMES MORE ENERGETIC WITH
THE APPROACH OF AN UPPER LEVEL TROUGH OVER THE CENTRAL
CONUS...SOUTHERLY FLOW WILL HELP ADVECT A WARM/MOIST AIRMASS
NORTHWARD. SHOWERS WILL BECOME A POSSIBILITY LATE IN THE FORECAST
PERIOD AND WITH THE EXPECTED MOISTURE RETURN...DO THINK THUNDER
WILL BE A POSSIBILITY AND SO HAVE INCLUDED SLIGHT CHANCE THUNDER
DURING THIS TIME.

.AVIATION...
FOR THE 12Z TAFS...

MVFR CIGS STILL ON TRACK TO CLEAR THE AREA THIS MORNING BUT HAVE
BEEN MUCH SLOWER THAN ORIGINALLY ANTICIPATED. ISSUANCE OF 12Z TAF
ACTUALLY WAS DELAYED A COUPLE OF MINUTES WITH THE EXPECTATION
THAT ORD WOULD SCATTER OUT...AND INDEED IT DID RIGHT AT THE END OF
THE TAF ISSUANCE WINDOW. SATELLITE IMAGES SUGGEST THE RAGGED BACK
EDGE COULD SUPPORT SOME OCCASIONAL BKN CIGS AT ORD BEFORE SKIES
FULLY CLEAR...SO MAINTAINED AN HOUR OF TEMPO TO ACCOUNT FOR THIS.
FOR MDW...BEST ESTIMATE IS FOR A COUPLE MORE HOURS OF BKN.

NORTH WINDS SHOULD RELAX AND GRADUALLY WORK AROUND TO THE EAST BY
AFTERNOON WITH A PERIOD OF LIGHT AND VARIABLE WINDS LIKELY THIS
MORNING.

LENNING

&&

.MARINE...
312 AM CDT

A HIGH PRESSURE RIDGE MOVING ACROSS THE LAKE GENERALLY WILL TURN
WINDS FROM NORTH AHEAD OF THE RIDGE THIS MORNING TO SOUTH BEHIND
IT THIS AFTERNOON...THOUGH ON THE SOUTH HALF NEAR THE CENTER OF
THE RIDGE THE WINDS LIKELY WILL BE HIGHLY VARIABLE FOR MOST OF THE
DAY. BY TONIGHT THE RIDGE MOVES TO THE EAST AND ALLOWS WINDS TO BE
MORE CONSISTENTLY FROM THE SOUTH TO SOUTHEAST.

SATURDAY NIGHT A LOW PRESSURE SYSTEM CROSSES THE LAKE AND VEERS
THESE SOUTH TO SOUTHEAST WINDS AROUND TO THE WEST AND EVENTUALLY
NORTH AGAIN BY SUNDAY NIGHT.

LENNING

.LOT WATCHES/WARNINGS/ADVISORIES...
IL...NONE.
IN...NONE.
LM...SMALL CRAFT ADVISORY...NEARSHORE WATERS
     UNTIL 10 AM FRIDAY.
