After a cold March (Indianapolis ran 4 F below average) and open to April, changes are on the horizon.
Before going further, March was always expected to be the coldest month (relative to average) of meteorological spring. For new subscribers, you can find our Spring Outlook here.
Looking ahead, note the rather dramatic shift that takes place at 500mb from the immediate term (image 1) to the medium range (or 6-10 day) period in image 2 below. Say goodbye to that AK ridge and subsequent downstream trough/ associated cooler than normal conditions.
This will likely result in the warmest air since October by the time we get to this weekend. High temperatures into the lower to middle 70s are a good bet this weekend. Saturday looks mostly dry before a few t-storms enter into the picture by Sunday.
As we look forward, additional unsettled conditions are a good bet early next week, along with seasonable to warmer than average conditions continuing.
