After 1-2" of snow area-wide, it has completely changed over to light freezing rain & freezing drizzle. Untreated roads & surfaces are covered in snow & ice. Neighborhoods that have untreated streets & snow0packed by traffic have a layer of very slippery ice atop the snow. Surfaces from trees to mailboxes to fences are being coated in a veneer of ice. There is also fog developing in the area.
I measured 1.1" of snow here at West Lafayette & so far 0.02" of freezing rain/drizzle.
Current temperatures range from 27-32 over the viewing area with east winds at 5-13 mph.
The next 11 hours show areas of light freezing rain & freezing drizzle with fog around well into the night. Minor ice accretion will occur area-wide of less than 0.10". Temperatures should slowly rise & level off at 30-33. There will also be fog around.
Some lingering patchy light freezing drizzle tomorrow morning with fog will give way to the redevelopment of widespread freezing rain over the area tomorrow mid morning.
The duration of freezing rain south of a Pine Village to Battle Ground to Kokomo line looks fairly brief. However, an extended period of freezing rain with ice accumulation is likely along & north of this zone. In fact, the far northeastern part of the viewing area may not go to all plain old rain until 3 a.m. early Tuesday morning.
So, 0.10" glaze ice accretions may be common along & north of that Pine Village to Battle Ground to Kokomo line with up to 0.25" of ice in the far north & northeast.
Given winds increasing from the southeast with gusts to 30 mph, a few isolated power outages may occur in the north later tomorrow & some dead limbs & snags may come down.
Rain Tuesday morning will be followed by a brief break with fog & suddenly light winds. However, rainfall will revelop near midday. This will quickly change to snow & be accompanied by a sudden significant increase in the wind as it turns to the northwest.
Temperatures will tank with accumulating snowfall & northwest winds sustained at 15-30 mph with gusts 40-50 mph. Isolated gusts to 55 mph are possible.
Conditions will worsen pretty rapidly after 1-3 p.m. over the area as temperatures drop from 37-44 to the 20s quickly.
Worst conditions for wind & snow look to occur Tuesday evening in the 5-9 p.m. time frame.
Slippery travel & widespread, significant blowing & drifting snow are expected, despite only 1-2". However, new data suggests some snow banding in the area with localized 2-4" amounts. We will monitor.
The main snow will pull away by late Wednesday night, but some snow showers & flurries may linger with an additional dusting into Wednesday morning. It will remain blustery right into Wednesday morning with northwest wind gusts to 32 mph.
Count on slick roads & blowing & drifting snow with pretty bad conditions Tuesday night to Wednesday morning.
Another powerhouse storm still looks likely Thursday-Friday. Pretty bad conditions with slippery roads & blowing & drifting snow are possible. Rain & 40s will rapidly go to 20s & howling winds with snow.
