Snow Showers And Squalls Continue Into Wednesday Morning


As expected the combination of colder air aloft, upper air disturbances rotating around the main upper low, and a long fetch off of Lakes Superior and Michigan have created convective snow showers/squalls in Central Indiana. It's one of those days where you can from sunshine to near-whiteout conditions within a matter of moments.

The snow shower/snow squall machine continues to crank over Central Indiana and coverage peaks this evening. Since they're convective in nature it's possible some cells contain lightning and/or graupel this evening.

While roads today remain mainly wet before sunset, we're expecting untreated roads/surfaces to become icy after overnight into the Wednesday morning commute.

Some areas of Madison, Grant, and Delaware counties have already had an inch of snow in heavier showers this morning. Some areas get another good coating to locally 1"+ the next 24 hours.

These bursts also cause quickly changing visibility and require caution and your attention if traveling.

Snow showers lingering until at least midday Wednesday before the flow off of Michigan shuts down and we set the stage for the best day of the week... Thursday. That's when we're getting abundant sun and afternoon temperatures close to 50°.

Unfortunately model trends continue to point toward a colder solution for late-week into the weekend. We've discussed the uncertainty of a frontal boundary location. It appears it will set up near the Ohio River Friday...keeping us on the colder but dry side of the front. At this time we're sunshine to start Friday with increasing clouds in the afternoon with dry conditions for the St. Patrick's Parade in downtown Indy.

But there's growing agreement on a rather raw St. Patrick's Day this Saturday. This includes a wintry mix that may last into the afternoon and temperatures struggling to hit 40 degrees. Sunday is easily the better day of the weekend with sunshine and highs in the lower 50s.

The pattern next week looks colder than average and with another potential wintry weather too. In fact... due to a blocking pattern in the North Atlantic it's looking like much of the next two weeks likely end up being below average for temperatures with above normal precipitation. Winter weather could very well linger the rest of the month - Sean Ash
