Powerful Storm System Impacts Many This Week


We're enjoying a tranquil March day in Central Indiana today with sun and seasonably cool temperatures in the 40s.

Near carbon-copy conditions Tuesday with highs finishing near 50 under a sky of sun and clouds.

Then all eyes point toward the west where merging pieces of upper energy create rapid strengthening of low pressure in the Central Plains on Wednesday. Due to continued model consistency...there's a high probability of heavy snow and possibly blizzard conditions from Colorado to the US/Canadian border.

Central Indiana will be on the warmer side of this system and the features 60s here on Wednesday and possibly 70s Thursday... which could be our warmest day since October.

Local impacts include the potential of high non-thunderstorm wind gusts exceeding 60 mph Thursday. The non-thunderstorm gusts could impact a large area of Central Indiana and we'll need to monitor for power outages and damage if these trends continue.

In addition, but on a smaller scale perhaps, is the possibility of severe storms. Newest data has increased low-level moisture fields which would up the ante for supercells given the modeled wind environment. There's lower confidence in severe storms verifying, at this time, versus it seems highly likely Thursday produces at minimum Wind Advisory criteria. Please check back for updates and changes.

The warmth is brief as we're back to near 40 for highs Friday and Saturday. Plan on cloudy conditions with spotty mixed showers if you're going to the Indianapolis St. Patrick's Day Parade on Friday. If you're waiting to celebrate on the actual St. Patrick's Day (Sunday) then you're in for a sunny and lower 50s treat!
