April so far has run much warmer than normal across our region, and a large part of the country. However, a rather significant shift in the pattern will take…

After a warm open to April, we note the MJO is heading into Phase 2 in the medium range. Phase 2 this time of year would imply for a cooler than normal pattern.
Sure enough we see the modeling going towards the cooler look for Week 2 (around 4/17…give or take a day, or two).
Note the GFS ensembles reverse course towards a cooler regime after the warm period currently.
The European ensembles (left) show a tendency for eastern troughiness, as well.
This isn’t saying some sort of record-smashing cold pattern is coming or anything of that sort, but it is to say that after a warm open to April, we’ll reverse things for a few days, at least, during the medium range period. This could include a push of frost and freeze conditions, as well.
In the shorter-term, please remain weather aware tonight and keep close tabs on watches and warnings issued by the National Weather Service. Thunderstorms should push into central Indiana around midnight and will be capable of severe levels, including damaging hail, destructive straight line winds, and quick spin-up tornadoes.

Enjoy Today; Very Busy Times Coming…Let’s get the easy and good stuff out of the way first- today will feature simply stunning weather conditions across the region. Wall-to-wall sunshine and temperatures climbing into the middle 60s after a chilly start! Enjoy!
A warm front will lift through the state late tonight and Thursday morning. This may help ignite scattered thunderstorms early Thursday morning. We’ll then see a “lull” in the action before additional waves of thunderstorms rumble in during the afternoon and evening. Some of these storms may reach severe limits with hail and damaging straight line winds of greatest concern.
A secondary area of low pressure will slowly traverse the Ohio Valley Friday and deliver widespread moderate to heavy rain. As the low scoots to our east, it’ll help pull much colder air into the area. Temperatures will fall through the day and rain will begin to mix with wet snow Friday night. While we won’t deal with accumulation here, areas from northern Indiana over to northern Ohio may pick up a light slushy accumulation of snow.
We’ll clear things out just in time for Saturday, but it’ll be a cool and breezy day, especially early. Most of Easter Sunday will also feature sunny and pleasant conditions, but moisture will increase late and we’ll mention the chance of showers by evening.
Early next week is back to the active regime with multiple waves of showers and thunderstorms Monday and Tuesday. Heavy rainfall and embedded strong to severe thunderstorms will be possible.

We’re shifting gears into more of a spring like weather pattern over the course of the next 4-6 weeks. Things appear to get rather active and warmer than average, as…

Evening Rain…The day has started unseasonably cold and sunny, but changes are in the offing later this afternoon. Breezy south winds will help temperatures moderate from the very cold morning readings. In fact, if we hang onto the sunshine long enough, south winds will combine with the extra sun to allow temperatures to rise close to 50 degrees. As it is, we anticipate increasing afternoon clouds followed by showers arriving towards mid to late afternoon. These showers may even be accompanied by an embedded rumble of thunder. Rainfall amounts won’t be heavy and most can expect to accumulate between 0.10″ to less than 0.25″.
We’ll enjoy a nice stretch of sunshine and moderating temperatures Monday through Wednesday. A clipper system should stay well north of our region Tuesday, but if your travels take you into northeastern portions of the state or to Ohio, expect a few showers.
The next storm system of note here will arrive Thursday. A cold front will deliver showers and thunderstorms, especially during the afternoon.
Another area of low pressure will deal a chilly rain to Indiana to wrap up the work week, but the good news in that sunshine appears to be the rule as we head into the special Easter weekend.
