Snow today will get everyone’s attention. Cutting to the chase: We look for snow accumulations today of 1-4” from I-70 northward. South of I-70, we see potential for a coating to an inch. The farther south you go, the less the chance of snow. Coverage of precipitation today will be 80% of the state. The cold air that has come in as of late has made the ground cold enough to support the accumulations. Snow will be with us through the entire day today, through tonight and will end tomorrow. The steady snow ends by shortly after sunrise tomorrow, but we see lingering on and off snow and flurries possible through the entire day tomorrow. Travel will likely be a little difficult today, especially over central Indiana, where dealing with a late season snow always triggers more anxiety. The map above shows potential snow accumulation through sunrise tomorrow morning.
Cold air holds through at least midweek. We see a shift in wind for the later part of the week and the south flow will moderate temps somewhat. However, we likely will not push to above normal temps until sometime this weekend. Our next weather system moves in for Friday. We can start the day with some light snow over the northern half of the state as temps will be below freezing. However, the moderating air will switch all precipitation to rain by shortly after sunrise. WE look for rains of .25” to .5” over about 80% of the state. Action should be done by midnight Friday night.
The weekend will feature clouds and some sun, and temps will continue to moderate. WE look for temps above normal by Saturday afternoon.
Next week, we have a system that sags slowly across the state from NW to SE for Monday night through Tuesday. This system does not have nearly as much moisture and coverage as the previous two. WE like rains of a few hundredths to perhaps .4” with coverage at no better than 60%. Our bias will be toward less moisture too, unless this system is able to find a better moisture source. Following that, we are mostly dry for the rest of the week.
In the extended window, we are still watching a potential frontal passage around the 24th into the 25th with rains that can be from .25”-.75”. But, most of the attention today will be paid to the snow that is flying over a large part of the state. Be careful!
