Client Brief: Severe Weather Event Overnight-Predawn Saturday…
Updated 12.10.21 @ 7:29a
Type: Severe weather event
What: Severe weather outbreak
When: 12a to 8a Saturday, 12.11.21
Severe Risks: Damaging straight line winds and tornadoes
Summary: A strengthening surface low pressure system will lift northeast out of the central Plains this morning into the Great Lakes region by Saturday morning. A strong cold front will trail the area of low pressure and press east across Indiana Saturday morning. Ahead of the front, unseasonably warm and humid air will be drawn north to encompass most of the state. We’ll really notice a surge in moisture levels as we progress through the afternoon and evening hours. Dew points will rise from the 40s now into the lower and middle 60s all the way north to include central Indiana during the overnight and predawn hours Saturday. While CAPE (convective available potential energy) will be in question, which is typical with late fall/ early winter severe set-ups, the concern here is that we’ll be able to, unfortunately, make up for that with the influx of moisture and abundant shear.
Showers and perhaps a rumble of thunder (nothing severe) will increase by evening across central portions of the state, but it’s not until we get closer to midnight that stronger storms should get triggered. The focal point of this particular severe weather episode will fall within the 12a to 8a range. Initially, we believe there will be the opportunity of discrete super cells ahead of what should become a rather robust squall line that will move across the state (west to east) between 6a and 8a Saturday. The potential is present for all modes of severe weather, but given the dynamics in play, we’re most concerned for the potential of damaging straight line winds and tornadoes. It’ll be important to ensure you have a means of getting the latest warnings that will likely be issued tonight (be sure to set those weather radios alerts to “on”). Add in the fact that this event will take place when most people are sleeping, coupled with the likelihood of storms racing off to the east and northeast, it wouldn’t be a bad idea to give your neighbors and loved ones a friendly heads up of the developing weather situation later tonight so they, too, can prepare.

Client Brief: Severe Weather Event And Flash Flood Potential…
Updated 06.18.21 @ 5:37p
Type: Severe weather event
What: Severe weather event and flash flood threat
When: This afternoon through tonight
Severe Risks: Damaging wind, large hail, embedded tornado potential, flash flooding
Summary: A complex of thunderstorms to our north this morning will diminish. As a result, the cloud canopy engulfing much of the region this morning will give way to mostly sunny skies late morning and into the afternoon. Intense heat is expected this afternoon, courtesy of a southerly flow ahead of an approaching warm front and upper air disturbance. Highs will reach the lower to middle 90s this afternoon and heat indices will climb to between 100° and 105°. This heat, combined with a multitude of other ingredients: dew points into the 70s, convective available potential energy (CAPE) in excess of 4000 j/kg (suggestive of extreme instability), and steep low level lapse rates (rate of temperature change with height) all will play into what looks like a significant setup for a severe weather outbreak later this afternoon and tonight.
Initially, individual cells are likely to erupt (targeting mid to late afternoon) along an OFB (outflow boundary) across n-central Indiana. Damaging wind and large hail are the biggest concerns with these cells, but a tornado threat is also on the table in this highly unstable environment. Eventually the scattered, intense cells should congeal into more of a widespread storm complex by evening and impact most of central and southern parts of the state. Precipitable water values will be in excess of 2” and promote a flash flood risk, especially if thunderstorms back-build and train over the same communities. Should this be the case, localized rainfall amounts of 3”-4” will be a good bet. As we progress into the overnight hours, the storm complex and associated flood risk will shift downstate.
