Mid-week warm-up begins

Arguably the best weather across the country is right here in central Indiana! Sunshine and highs in the 70s today are just scratching the surface of the well advertised warm up.

Very pleasant conditions hold up for any outdoor evening plans, with temperatures staying in the 60s well after dark. The passage of a warm front early Wednesday morning triggers a wind shift to the south-southwest, which will be the conveyor belt to our warmest air in some seven months.

Our streak of sub-80 degree days will be snapped tomorrow as highs climb well into the 80s. The tradeoff will be a gusty southwesterly wind that may reach 30mph during the afternoon.

This air mass remains firmly in place for another unseasonably warm day Thursday in the 80s.

Our next chance of organized rain and storms arrives with a cool front Friday. Though we’re not expecting severe weather, locally heavy rain will be likely as the air becomes more humid.

There is much model uncertainty regarding the evolution and dissipation of this front for the weekend. One solution suggests the front stalls and serves as an igniter of scattered storms Saturday and Sunday. Another solution is for decreasing rain chances as upper level ridging (sinking air that suppresses cloud/storm development) builds across the region. At this point it’s too early for specifics, and we’ve opted to leave the ongoing weekend forecast. But changes in either direction are likely due to the diverging model solutions presently.

Have a great evening and hope you get a chance to enjoy the weather.
