Mother Nature’s been painting in bold strokes since Sunday, with the biggest snow in five years and the coldest temps in twenty years. Now: the swings won’t be as sharp, but I do have some twists and turns through the weekend.
The snow/sky combo of bright white and sunlight gave way today to thickening clouds that are likely to stay through Saturday.One benefit? Clouds (along with the departure of Arctic air in general) will keep temps pretty steady at just above zero. Chills will run as low as ten below. Beats forty below! The Wind Chill Warning expires at 7pm.
The clouds arrive along with a stationary front that will set up shop over Indiana through Friday, and help to feed a couple of small-time weather makers. A dusting of snow is possible tomorrow, mainly in the afternoon, and mainly north of Indianapolis. It would dissipate quickly Wednesday evening
A better chance of light snow arrives Thursday, but we’re still only talking an inch or less in central Indiana. An inch or two is possible in the northern quarter of the state. Highs will be in the mid 20s Wednesday, but should get close to freezing Thursday.
One note for Thursday night and early Friday morning. It’s possible that as milder air pushes in the higher levels of the atmosphere precip could fall as a liquid that freezes upon reaching the colder ground below. Any amounts appear to be very light, but it could be a little slippery Thursday night and early Friday morning. That wedge of colder air at the surface should warm to above-freezing level Friday morning, and rain chances kick in Friday afternoon and become likely Friday night.
You’ll wake up to a cold rain Saturday, which should fade in the afternoon. Saturday Night should be quiet, but Sunday brings another rain chance, maybe with snow later.The biggest threat over the next few days comes from the unwelcome moisture Friday night and Saturday morning. Up to an inch of rain may fall in central Indiana. Interestingly enough, that’s about exactly the amount of moisture Indy collected Sunday. The liquid count was 1.12″ inches, which led to 11.4 inches of snow. On Monday morning it seemed you’d be looking at it forever, but at least one computer model sees most of it gone by Sunday.
