What happened

The episode as NWS IND wrote it up.

A powerful winter storm moved across the United States, bringing severe winter weather to central Indiana from January 31 through February 2. Freezing rain, sleet, snow, strong winds, and arctic air impacted the state. Indianapolis received 0.6 inches of ice and 1.0 inch of sleet from the storm. The first wave of precipitation fell during the evening of January 31, and this precipitation was mainly freezing rain and sleet, with a little snow across the northern parts of central Indiana. The second wave of precipitation began in earnest during the afternoon of February 1 and continued into the overnight hours. Far northern sections of central Indiana saw snow, with a sleet/freezing rain mix across much of the central part of the area. Across the south, mainly freezing rain was noted. After the strong area of low pressure passed over the area, winds increased with gusts over 50 mph reported. This wind created blowing and drifting snow across the north, and caused trees and power lines to come down across areas that saw freezing rain. Travel became near impossible at many locations, with several counties across central Indiana restricting travel. As the storm moved across the state, warm air briefly moved into central Indiana warming temperatures to above freezing across parts of the area. The warmth was brief though, as Arctic air flowed into the area after the storm passed. Temperatures dropped to near zero in some locations by the morning of February 3.

.UPDATE...

THE AVIATION SECTION HAS BEEN UPDATED BELOW.

&&

.SYNOPSIS...

A POTENTIALLY CATASTROPHIC WINTER STORM WILL CONTINUE TO IMPACT
CENTRAL INDIANA THROUGH WEDNESDAY...WITH A WIDE VARIETY OF
PRECIPITATION TYPES AND SIGNIFICANT ACCUMULATIONS EXPECTED. IN
ADDITION...ARCTIC HIGH PRESSURE PLUNGING INTO THE CENTRAL PORTION OF
THE COUNTRY BEHIND THE STORM WILL RESULT IN STRONG GUSTY WINDS
TUESDAY AFTERNOON INTO WEDNESDAY...EXACERBATING THE SITUATION. THE
HIGH WILL ALSO RESULT IN COLDER TEMPERATURES LATE THIS WEEK AND THIS
WEEKEND.

&&

.NEAR TERM /TONIGHT/...

SECOND MAIN WAVE MOVING THROUGH CENTRAL LATE THIS EVENING SHOULD
MOSTLY MOVE OUT INTO OHIO OVERNIGHT WITH PERHAPS POCKETS OF LIGHT
FREEZING RAIN OR DRIZZLE THE REMAINDER OF THE NIGHT. SOME AREAS
COULD SEE A QUARTER INCH OR MORE TOTAL ICE ACCUMULATION BY
MORNING...AND NORTHWEST PARTS OF CENTRAL INDIANA COULD SEE 3 TO 4
INCHES OF SNOW AND SLEET ACCUMULATION.

STUCK NEAR MAVMOS WHICH APPROXIMATES SURFACE WETBULB TEMPERATURE
PROGS.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...

SECOND MORE POTENT WAVE OF THE WINTER STORM WILL IMPACT THE AREA
TUESDAY THROUGH WEDNESDAY AND THIS REMAINS THE FOCUS. GFS HAS BEEN
RELATIVELY CONSISTENT AND ALSO REPRESENTS SOMEWHAT OF A COMPROMISE
SOLUTION BETWEEN THE RANGE OF GUIDANCE...AND IS ALSO SUPPORTED BY
HPC MODEL DIAGNOSTICS. HAVE GENERALLY LEANED TOWARD ITS SOLUTION.

GUIDANCE HAS COME IN SLIGHTLY COLDER OVERALL...WHICH REPRESENTS A
SLIGHT SHIFT IN EXPECTATIONS TO THE SOUTH...BUT NOT MAJORLY
DIFFERENT THAN PREVIOUS FORECAST. THUS...ONLY TWEAKS MADE TO
PRECIP TYPES ACROSS THE AREA.

ALL INDICATIONS REMAIN THAT AN EXTREMELY STRONGLY FORCED SYSTEM
WILL PASS ACROSS THE AREA...WHICH PRECIP TYPE REMAINING THE ONLY
REAL QUESTION.

MODEL SOUNDINGS CONTINUE TO INDICATE MAINLY ALL SNOW NEAR
LAF...WITH POTENTIALLY SOME SLEET TUESDAY NIGHT. EXPECTATION IS
THAT A LARGE PORTION ALONG THE INTERSTATE 70 CORRIDOR WILL SEE
FREEZING RAIN OR A MIX OF FREEZING RAIN AND SLEET FOR MUCH OF THE
EVENT...WITH SLEET MORE LIKELY THE FURTHER NORTH ONE GOES. STILL
EXPECT THAT SOME ABOVE FREEZING SURFACE AIR MAY PUSH INTO THE
SOUTHERN TIER OF THE AREA MAINLY TOMORROW EVENING...AND HELP TO
CUT DOWN SLIGHTLY ON ICE ACCUMULATIONS THERE.

AS THE STORM EXITS THE AREA...MUCH COLDER AIR WILL PUSH INTO THE
AREA LATE TUESDAY NIGHT INTO WEDNESDAY...AND REMAINING PRECIP WILL
CHANGE OVER TO SNOW. LIGHT ACCUMULATIONS MAY BE POSSIBLE MOST
EVERYWHERE THEN.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH NEXT SUNDAY/...

SLIGHT CHANCE FOR SNOW WEDNESDAY NIGHT AS A WEAK UPPER TOUGH
MOVES THROUGH...OTHERWISE...ARCTIC AIR WILL BUILD IN ALLOWING DRY
BUT VERY FRIGID WEATHER ESPECIALLY IN THE SNOW PACK BUT EVEN IN
AREAS THAT RECEIVE THE DREADED ICE WHICH COULD EXACERBATE THE
EXPECTED POWER LOSS. WENT BELOW ZERO NUMBERS ESPECIALLY EARLY IN
THE EXTENDED.

&&

.AVIATION /DISCUSSION FOR THE 010600Z TAFS/...

MOSTLY IFR CONDITIONS EXPECTED THROUGH THE PERIOD...WITH LIFR
POSSIBLE.

FIRST WAVE OF PRECIPITATION WILL BE EXITING OR ABOUT TO EXIT THE
SITES AT VALID TIME. BEHIND THIS THERE WILL BE PATCHY LIGHT
PRECIPITATION AND FOG UNTIL THE NEXT SIGNIFICANT WAVE MOVES IN
DURING THE AFTERNOON HOURS.

TRIED TO SHOW THIS TIMING IN TAFS WITH LIGHTER PRECIPITATION IN
BETWEEN.

KLAF STILL LOOKS TO BE PREDOMINANT SNOW WITH SLEET MIXING IN AT
TIMES. ELSEWHERE FREEZING RAIN WILL BE THE PREDOMINANT TYPE...WITH
FREEZING DRIZZLE IN BETWEEN WAVES OF PRECIPITATION.

WINDS WILL INCREASE DURING THE DAY TUESDAY...WITH GUSTS NEAR OR OVER
30KT EXPECTED BY MID AFTERNOON INTO THE EVENING HOURS TUESDAY.

Brown County Chief Deputy Coroner Earl Piper says 93-year-old Thomas Pat McGuire died of hypothermia on Tuesday night outside his rural Morgantown home about 15 miles northeast of Bloomington as freezing rain and strong winds swept the area. He says McGuire broke a window in his front door after locking himself outside of his northern Brown County home, but apparently couldn't reach the lock. Piper says McGuire was not wearing a coat. He says McGuire was apparently walking toward his daughter's nearby home when he succumbed to the cold. McGuire's daughter found his body Wednesday morning.
