Since yesterday morning, an additional 0.3-3" of snow has falln over the area with the highest amounts in our far northwest.
Total snow depth in the area varies from 3.5" in the far south to up to 12" in our far northwest. Depth around Greater Lafayette is running 4-5".
In addition to the system snow yesterday & the fluffy lake effect snow showers today, we had a period of freezing drizzle for part of the area for a while lastnight.
At one point it was 18 with freezing drizzle at our WLFI ob site.
How do you get freezing drizzle at 18? I will have a separate blog post on this set-up later this evening.
We two, potentially 3 impactful winter weather systems over the next 9 days to discuss........then a big warm-up with sudden thaw, melt with rain.....
First things first.............
Scattered lake effect snow showers & flurries will be with us off & on today with some sun. Highs will run 21-28, followed by teens tonight.
An ice storm is expected from Texas to the mid-Atlantic tonight-Thursday night. Heavy icing is expected especially from northeastern Arkansas through Kentucky with up to 0.75" of ice & tree & powerline damage expected.
Here, it looks like all snow Wednesday.
It looks like snowfall amounts will vary from 0.5" to 4" in the viewing area with 1-2" amounts being the most widespread.
I felt pretty confident that the highest snowfall amounts would be in our southern areas yesterday & although model data is very wobbly back & forth on placement of higher amounts, I still prefer the notion that the higher side of those amounts will occur over Montgomery County with lesser amounts as you go northward.
The high-res NAM model appears to capture this the best right now.
We will continue to monitor & IF tweaks need to be made, they will be made. That is still possible, so be aware & prepared for that.
This snow would tend to fall in the 2 p.m. to 1 a.m. time frame Wednesday.
Winds will be gusting to 21 mph from the northeast Wednesday & up to 30 mph Wednesday night.
This will lead to some blowing & drifting snow, especially Wednesday night (greatest on northwest- to southeast-oriented roadways).
Highs Wednesday will run 22-27 with teens Wednesday night.
A few snow flurries/showers are possible Friday from Lake Michigan & from a cold front passing through. Highs will run 15-24 north to south. Temperatures may fall to 12-20 in the afternoon with north winds 15-25 mph.
Lows of -5 to 5 are expected Friday night with wind chills -21 to -10.
With some sunshine, highs of 9-15 are expected Saturday with wind chills -5 to 5.
Another ice storm could occur Texas to the Northeast Saturday-Monday. Meanwhile we are looking at snow here Sunday with strong northeast winds to 35 mph.
Winds may gust to 45 mph Sunday night. This could lead to widespread blowing & drifting snow with reduced visiblities.
Accumulations is expected it is just unclear how much.
Highs of 16-22 are expected Sunday & lows -2 to 10 Sunday night with wind chills -21 to -8.
With north winds 15-25 mph Monday, highs in the teens to 20 will occur with wind chills of -2 to 8.
Some scattered lake effect snow showers & flurries are possible.
After highs in the teens & 20s Tuesday & Wednesday of next week with lows 0 to single digits to then teens, it appears we may deal with our own icing issues around Thursday of next week.
It appears that much of the area may have ice, though it may end up as all snow near Morocco to Demotte. There could even be a change-over to rain in our southeastern counties for a while.
This bears watching in a pattern very favorable for ice storms from Texas to the Northeast with the eastern U.S. cut in two pieces. Brutal cold will reside in the Northern Plains with spring-like warmth in the Southeast.
Highs may reach 27-37 northwest to southeast next Thursday with around 33 at Greater Lafayette.
The February 21-22 system looks like ALL RAIN & rain all the way to Ontario with 50s there & even some 60s not far away.
Biggest problem will be SUDDEN melt-down with potentiall 1-1.5" of rain falling on top of that. Ice jams may become an issue on creeks & streams, as well.
Effects of the Sudden Stratospheric Warming Event usually occur 30-60 days with colder weather. So, we should see the lingering effects depart by early March & much warmer pattern settle in.
