***Wind Chill Warning until 1 PM Thursday***
Indianapolis tied a daily record this morning with a low temperature of -11... with many cities north of I-70 near -20 earlier. What makes that temperature noteworthy in Indy is the lack of a deep snowpack, which is typically needed to reach those low levels.
Of course the gusty wind makes it much worse and dangerous... producing wind chills of -45 to -30. In fact, this is only the 5th day in Indy over the past 30 years with a wind chill of -35 or colder.
The "high" temperature in Indy today (which occurred at midnight) of 3 is the coldest "high" in the city since 1996... and marks on the 47th day since 1871 with of 3 or colder. Truly rare air for Central Indiana.
Please limit outdoor time and layer-up considerably if you must venture out. Though wind speeds ease by 5-6 PM, temperatures and wind chills remain well below zero. Indy will near another record low (-11) again overnight into Thursday morning.
But the harshness eases Thursday with highs near 20. Then focus quickly shifts to clipper system snowfall between Thursday 7 PM and Friday 10 AM...with possibly a swath of moderate accumulation near/north of I-70 during that time.
Our initial snowfall forecast is for 1" to 3" along and just south of I-70 and 3"-5" north and northeast of downtown Indy. Please realize this subject to change and we do expect a sharp drop-off in snow amounts going south and southwest.
We're still forecasting a weekend warm up but it comes with a a good deal of fog Saturday. But 50s ahead for Sunday and Monday when it will "feel" 95 to nearly 100° warmer than today.
