Not much going on today, as we experience the “calm before the storm”. Clouds will be thickening as the day progresses, due to the approaching system that brings us action tomorrow. We expect no new precipitation today.
Snow will move across the state tomorrow. Action in the morning will be in SW and west central parts of the state, but it will spread quickly, and we see good snows through the midday and afternoon hours. The majority of the snow will be winding down by midnight Saturday night. We are leaving our forecasted snow totals unchanged, expecting a coating to 2 inches over the northern third of the state, and 2-6” in central and southern Indiana. We won’t rule out the potential for some 3-inch totals near the US 24 corridor. We think the heaviest snows may end up in central and southern Indiana, but we have a renewed concern this morning about some rain mixing in in far southern Indiana, as temps climb tomorrow in to the upper 30s. Any rain would decrease the snow potential, of course. On Sunday, we see light snow and flurries end in the early morning in NW parts of the state, and then slowly over the rest of the state from NW to SE as the day progresses. The map at right shows updated snow potential through Sunday night.
We will be dry for Monday through Thursday of next week. Clouds increase Friday, as we are pushing back our next system again by about 12 hours. We have a chance of snow developing in the north, and rain in the south, with a few hundredths to .4” of liquid equivalent precipitation over about 60% of the state. The heaviest action will be in the south, where rain is most likely. We turn dry again to finish next weekend, Saturday and Sunday, but we also turn much colder, looking for temps below normal.
The cold theme remains for the 11-16 day extended period. We expect light snow and flurries off and on from the 21st through the 25th. These come like minor, clipper waves, bringing the potential for minor accumulations with each wave, but nothing earth shattering.
The winter storm tomorrow is likely the biggest event of this 2-week forecast. Be ready. The snow totals may not be epic, but with it being the first good accumulating snows of the year in almost every location of the state, things will be a mess.
