WEATHER ALERT DAY: Severe storms possible Friday

Friday is an ABC17 Stormtrack Weather Alert Day.

SETUP

The weather team is monitoring a threat for all types of severe weather on Friday as an upper trough of low pressure looks to bring through a more optimized combination of ingredients for thunderstorms capable of producing all types of hazards. This upper trough will be larger and stronger than the waves impacting the region earlier in the week. This should help clear the region of a somewhat stationary boundary and the clutter of rain and clouds that is associated with it. With more dry time, and potentially more sunshine, instability should have more potential to build. With the cap potentially weak enough for storms to develop in the afternoon and early evening, all types of severe weather could result as the parent system may possess enough low-level and deep-layer shear for organization through the storm.

TIMING

Timing is uncertain at this time, but current forecasts place this during Friday afternoon into the overnight hours, with actual rain chances peaking during the late night hours. This will likely be separate from our core severe risk timeline, as it would likely be earlier in the evening. Rain will likely linger into early Saturday morning.

IMPACTS:

All severe threats will be possible, including damaging winds, 1" or larger hail, and tornadoes. How likely these threats are will become clearer with time, but these are realistic possibilities given the overall setup. Given the wet start to the week, we'll also be concerned with flooding as a secondary or tertiary threat.
