April Turns Active: Timing Out Storms…

A series of storm systems will impact the OHV region over the next couple of weeks. As we look at the overall pattern, a negative NAO will begin to have significant influence on the overall pattern through mid-April. We note the mean trough position settles into the western portion of the country with a reflection of a southeast ridge in place. Accordingly, the Ohio Valley will find itself in the middle of the primary storm track as we progress through the middle part of the month.

With said pattern in place, precipitation is expected to run above, to significantly above, normal during the mid-month stretch.

After a gorgeous Saturday (sunshine and lower 70s), the first of a series of storm systems will begin to impact the region Sunday. A couple of strong to severe thunderstorms are possible across southern and central IN- especially during the afternoon.

Thereafter, additional dates to monitor for storm impacts include the following:

Wednesday night and Thursday- April 10th and 11th

Saturday and Sunday- April 13th and 14th

Wednesday and Thursday- April 17th and 18th

We’ll be able to get much more specific with these individual storms as we get closer! An updated video will hit this evening looking closer at Sunday’s storm threat. In the meantime, get set to kick off the weekend with superb weather!

Here Comes Spring: More Of A Substantial Warm-Up On Deck…

After a cold March (Indianapolis ran 4 F below average) and open to April, changes are on the horizon.

Coldest anomalies were located across the northern Rockies into the Plains during March with only the Four Corners and southern Florida escaping the unseasonably cold conditions.

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.

Heavy Rain Ends As Snow This Evening…

A wet day is in store for central Indiana as a wave of low pressure moves along a stalled frontal boundary this afternoon. Once that low scoots by, the front will get a shove to the southeast and much drier weather will return as we go through the 2nd half of the weekend. The transition in between will be a combination of heavy rain eventually ending as wet snow this evening. Let’s time things out:

This morning’s initial wave of steady rain is now pushing into Ohio (as we write this just before 9a). Scattered showers are left behind.

That said, another wave of steady and, at times, heavy rain will return early this afternoon. A couple of thunderstorms are possible across southern Indiana.

Precipitation coverage will be widespread from noon until around 8p, including additional rainfall amounts over 1″ in many spots across central Indiana. Localized ponding and low-land flooding will be a good bet this afternoon into the evening hours.

As the area of low pressure scoots to our east, it’ll help pull the cold front south through central Indiana during the mid to late evening hours. Accordingly, rain will transition to a period of wet snow between 6p and 8p across central Indiana. More specific to Indianapolis, we think rain will switch to snow around 7p.

While snow won’t last a long time and temperatures will be above freezing as the snow is falling, briefly heavy intensity will likely result in a quick wet coating to around an inch in spots from central parts of the state, including east-central Indiana.

All precipitation will exit the state before midnight. While we could have a couple of scattered snow showers early Sunday morning, most of the day will be dry with increasing amounts of sunshine as the day progresses. It’ll be much colder with highs not making it out of the 30s.

Improving weather conditions will build in here through the early parts of the work week, along with moderating temperatures, thanks to high pressure. – Much more on the week ahead and longer range later today with our PM video update.
