...POTENTIAL FOR SIGNIFICANT LAKE EFFECT SNOW ACCUMULATIONS OVER
PORTIONS OF NORTHWEST INDIANA THIS EVENING THROUGH MIDDAY
TUESDAY...

.COLDER AIR WILL SPREAD INTO THE REGION THROUGH THE EVENING
ALLOWING RAIN TO CHANGE TO SNOW. THIS SNOW WILL END EARLY THIS
EVENING BUT NORTHERLY WINDS WILL ALLOW LAKE EFFECT SNOW TO DEVELOP
AND AFFECT AT LEAST PORTIONS OF PORTER AND EVEN JASPER COUNTIES
TOWARD LATE EVENING...WITH SNOW MOST LIKELY OVERNIGHT AND EARLY
TUESDAY MORNING. CONFIDENCE IN HOW THE BAND EVOLVES IN TERMS OF
ITS POSITIONING IS FAIRLY LOW BUT IT WILL LIKELY SHIFT OFF TO THE
EAST LATER TUESDAY MORNING...WITH THE GREATEST UNCERTAINTY
SURROUNDING HOW QUICKLY IT DOES SO. GIVEN THE POTENTIAL FOR SNOW
TO FALL HEAVILY AT TIMES...WITH SEVERAL INCHES POSSIBLE IN THE
COURSE OF AN HOUR...AND COMBINED WITH 15 TO 25 MPH WIND...A LAKE
EFFECT SNOW ADVISORY IS BEING ISSUED. 3 TO 5 INCHES OF
ACCUMULATION IS EXPECTED...PRIMARILY ACROSS EASTERN PORTIONS OF
THE COUNTIES WITH ISOLATED AMOUNTS OF 6 OR MORE INCHES STILL A
POSSIBILITY. AS WITH MANY LAKE EFFECT SITUATIONS...THERE WILL
LIKELY BE A QUICK DROP OFF IN SNOW AMOUNTS AS ONE MOVES WESTWARD.
GIVEN THE UNCERTAINTY IN BAND MOVEMENT...AN UPGRADE TO A LAKE
EFFECT SNOW WARNING IS A POSSIBILITY IF IT APPEARS THAT THE BAND
WILL REMAIN OVER THE AREA FOR A LONGER DURATION.
