MESOSCALE DISCUSSION 0054  
NWS STORM PREDICTION CENTER NORMAN OK  
0942 PM CST TUE FEB 06 2018  
 
AREAS AFFECTED...SOUTHERN ILLINOIS...SOUTHERN INDIANA...SOUTHERN  
OHIO...FAR WESTERN WEST VIRGINIA...AND NORTHERN KENTUCKY  
 
CONCERNING...WINTER MIXED PRECIPITATION  
 
VALID 070342Z - 070845Z  
 
SUMMARY...AREAS OF FREEZING RAIN WILL CONTINUE TO MIGRATE  
EAST-NORTHEASTWARD ACROSS THE DISCUSSION AREA THROUGH 08Z.  
 
DISCUSSION...AREAS OF FREEZING RAIN CONTINUE ACROSS SOUTHWESTERN  
PORTIONS OF THE DISCUSSION AREA (ILLINOIS/INDIANA/KENTUCKY) AT THIS  
TIME. RECENT OBSERVATIONS SUGGEST ACCUMULATIONS OF .05 TO .13 INCH  
OF ICE IN THESE AREAS WITH PRECIPITATION CONTINUING TO FALL.  
DOWNSTREAM OF THIS REGION OF PRECIPITATION, FORECAST SOUNDINGS AND  
OBSERVATIONS SUPPORT A CONTINUED FREEZING RAIN THREAT EXTENDING  
EAST-NORTHEASTWARD ACROSS THE REMAINDER OF THE DISCUSSION AREA -  
ESPECIALLY AS PRECIPITATION MOISTENS/COOLS THE BOUNDARY LAYER. IT  
IS NOT OUT OF THE QUESTION THAT A FEW AREAS ON THE NORTHERN EXTENT  
OF THE DISCUSSION AREA MAY EXPERIENCE SLEET AND/OR SNOW MIXING IN  
WITH PRECIPITATION WHICH MAY RESULT IN SOMEWHAT LOWER ICE/FREEZING  
RAIN ACCUMULATIONS (BUT ALSO POTENTIALLY HIGHER SNOW TOTALS).  
 
LATEST OPERATIONAL/HIGH-RES GUIDANCE CONTINUES TO SUGGEST THAT BROAD  
AREAS OF PRECIPITATION WILL REDEVELOP TONIGHT OVER ARKANSAS AND  
MIGRATE EAST-NORTHEASTWARD THROUGH THE DISCUSSION AREA THROUGH AT  
LEAST 08Z. PRECIPITATION MAY BEGIN TO TAPER OFF IN WESTERN PORTIONS  
OF THE DISCUSSION AREA AROUND 10Z AND END LATER IN EASTERN AREAS.  
WHERE FREEZING RAIN IS THE DOMINANT PRECIPITATION MODE, RATES ABOVE  
0.05 INCH PER HOUR MAY OCCUR WITHIN HEAVIER PRECIPITATION BANDS.
