Weekly #AGwx And #Severe Outlook…

Weekly Highlights:

I. A cold front will settle south into a warm and at least marginally unstable environment tonight into early Sunday morning. This will result in a rather rapid expansion of thunderstorms across the central Ohio Valley tonight.

II. The next big item has to do with the unseasonably cold airmass that will unload into the eastern half of the country, but this is more of a late Week 1 into Week 2 situation.

Unseasonably dry conditions will continue to allow the Deep South to dry out over the upcoming week. Meanwhile, the Great Lakes region also should run drier than normal.

Across immediate central Indiana, we’re targeting the upcoming 7-day period to produce between 1.5” and 2” of rain and most of that will fall tonight-early Sunday morning.
A highly amplified pattern will emerge late in the forecast period resulting in the overall 7-day period tilting towards a cooler than average one. Even colder air is scheduled next weekend into Week 2.
The best chance of a few strong to severe storms will take place late tonight into early Sunday morning as a cold front settles south into a briefly warmer/ unstable air mass.

Forecast Period: 05.02.20 through 05.09.20

Most of our Saturday will feature dry and pleasant conditions. It’ll be a great day to get caught up on yard work around the house before things take on a stormy turn tonight. A cold front will settle into the briefly warmer and more humid air mass and will ignite thunderstorm development by late evening. A few of these storms will likely become strong to severe late evening into the overnight period, including the potential of large hail and damaging wind gusts. Once the front settles to our south, the convection will also move south and out of our area mid-late Sunday morning. Beforehand, a swath of 1” rains are likely throughout central Indiana with a few locally heavier totals.

There will then be a couple of additional cold fronts to track through the upcoming week: Monday night into Tuesday and again Friday into Saturday. Both fronts should provide additional rain chances during that time frame followed by cooler air.

It’s the weekend front that will usher in more of a winter-like feel including the threat of late season frost/ freeze conditions during the 7-10 day period. We may have not even seen the last of snow for the season…

Welcome To May: Threat Of Record Cold Week 2…

A gorgeous Friday is dialed up complete with plentiful sunshine and temperatures warming quickly from the mid and upper 30s into the mid and upper 60s.

A couple weak impulses of energy will scoot through the Ohio Valley over the next 24 hours and while they will spark a few showers/ embedded thunder predawn Saturday and again Saturday night, most of the daytime hours Saturday will also feature dry conditions.

That begins to change Sunday as widespread showers and thunderstorms are expected to rumble across central Indiana, especially during the morning hours. Locally heavy downpours are likely.

A quick 1”-1.25” is a good bet across the heart of the state with this system Sunday morning.

Dry conditions will quickly return Sunday evening into Monday thanks to high pressure briefly building back into the region. This will lead to a pleasant open to the work week with highs topping out in the middle 60s.

Unsettled weather returns as early as Tuesday with increased chances of showers and thunderstorms ahead of a strong cold front.

Though we’ll certainly turn cooler for the middle to latter part of the week, this will only be a precursor to what lies ahead behind yet another strong cold front late next week.

The air will likely challenge records into the Week 2 time frame (May 8th-14th), including the threat and increased likelihood of late season frost/ freezes. We also likely haven’t seen the last of the snow flakes for the season either…
