April has had afternoons in the lower 80s, temps running nearly 3° above normal, and started with some light snow showers after the 1st completely snowless March on record in Columbus.
Now we have snow on our doorstep and some very cold temps as well.
WHAT TO EXPECT:
Cold air is currently spilling into our area, with readings falling back into the 50s/40s/30s already with some areas in our southeast topping 70° earlier today. The moisture is also following the colder air a bit quicker, and this will lead more of us to see some snowfall overnight.
Tuesday night before midnight we could see some light wet snow mixed with some light rain showers north, especially in the higher elevations in the northwest.
As we get closer to midnight the colder air will start to progress east a little quicker and we will see more snow shower activity near the I-71 corridor.
In the next few hours the rain showers will be on the leading edge in the south, but as the rest of us will be cold enough, we will start to see snow in a good portion of Central Ohio. In fact, in the northwest we could see a few more moderate snow bands.
By 4am as the colder air is near the far southeast, we are going to see snow showers for most of our area, including east of I-71, and south of I-70. There could be some heavier banding along I-71 as well just before the morning commute gets going.
Even with warm road temps, the time of night, along with snowfall rates could put some slush down on the roads as the snow attempts to melt.
By daybreak, the moisture that pulls east following the colder air, and this will drag more snow east, and will taper it down to the west with colder snow showers, and a cold northwest breeze. Temps will fall to the lower 30s to near 30. Wind chills will start in the 20s.
By 8am we are now 75 mins past sunrise, and the bulk of the moisture should start to exit Ohio, with some wrap around moisture falling as some wet snow showers.
Most of the activity should be quite light by 10am with some flurries and lighter drizzle possible as temps warm up a bit.
By noon, we should see a few rain showers remaining in the southeast, with a colder breeze out of the northwest. Highs will only reach into the middle 40s on Wednesday, with wind chills staying in the 30s all day even with sunshine returning.
In fact, parts of our area, mainly west and northwest, are already under freeze watches and warnings for early Wednesday morning. This could be the period that not only sensitive plants/veggies/flowers need to be covered, but also pipes/hoses too!
It will be even colder Wednesday night into Thursday morning, where temps will likely fall into the 20s in most locations with some areas hanging onto the lower 30s. This will be a night were all the winter precautions are taken for cold temps. Hoses/outside water may freeze overnight. This freeze watch will likely be upgraded to a warning on Wednesday.
HOW MUCH SNOWFALL IN COLUMBUS BY WEDNESDAY:
It is important to remember that the road surface temps are quite warm, especially due to sunshine, and the fact its nearly a month into Spring. Most of the snowfall accumulations will be in grassy surfaces, metal roofs, tops of cars and so on.
If these numbers verify for Wednesday, that 1.9″ would fall just short of the record of 2.0″ of snowfall for the date, and only the 11th time on record we have had measurable snowfall on or after April 21st in the spring in Central Ohio.
Keep the gear handy to clear off the car, and make sure to stay bundled up for a cold and blustery Wednesday.
