Sorry everyone! I meant to get this final map out sooner & I became side-tracked with lots of other tasks. Thank you all very, very much for your totals! They are very helpful!!
This map is a combination of NWS COOP observers, CoCoRaHs observers & all of our NWS & WLFI area spotters.
Final snowfall for February 12-13 for the viewing area will go down as 2-6". Highest totals were in a strip in northern Newton County with 6" reported between Hebron & Demotte from farmer just south of the Kankakee River on Indiana 8. Southwest of Demotte, 4.2" was measured by CoCo observer.
The +6" totals were found just north of the Kankakee River in Porter County with 6-8". 7.1" was measured just northeast of Hebron from CoCo observer.
Lowest totals of 2-2.5" were found near Pine Village to Otterbein to Chalmers & Monticello.
This is a driving, spring-like rainfall tonight. Rates have been high for the time of year at 10:45 p.m. with temperatures 34-44 over the area from northeast to southwest.
Rainfall total at this WLFI site is 0.57".
Rainfall totals vary (so far) from 0.25-0.80" over the area with considerable ponding in areas that have seen +0.50".
Rain will taper to drizzle & temperatures will warm overnight to the 40s.
Dense fog is most likely in the 1-7 a.m. time frame before front whisks it away & winds turn brisk from the northwest.
Temperatures will also fall with passage of the front tomorrow morning.
A few sprinkles & flurries are possible tomorrow afternoon as temperatures fall to 34 by 1 p.m. with northwest wind at 15-25 mph.
Arctic high should shove winter storm west & south of our area. Many times you'd have to watch a big storm in the southern Plains for eventual big impacts here, but not this time.
Snow may fall from the Plains to parts of the Upper South.
We look cold though. We should stay mostly sunny Wednesday-Thursday with highs 27-33 Wednesday & 23-28 Thursday.
Lows will run as low as the single digits. If we had snow pack it would be much, much colder.
Friday should still be cold with highs below normal at 32-37.
Whether it is all rain or rain & snow Sunday-Monday will be determined by exact track of two waves of surface low pressure along a front. Looks like two main waves of precipitation. They add up to +1" of liquid.
Canadian & European models show more in the way of snow Sunday-Monday than rain. German ICON model is rain & snow mixed. GFS model is all rain. The French model shows the 540 thickness line south of our area Sunday-Monday which would mean snow.
Signs are that we will reach the 50s quickly Tuesday late as much warmer air comes in on south-southwest winds 20-40 mph with drizzle & some patchy rain as warm front lifts northward.
Cold front should pass Wednesday with showers & temperatures falling from 50 early to 38 by evening with wind shift to the west-northwest.
