Weather Impact Alert: Prepare for Challenging Weather this Weekend
Residents of Knoxville and surrounding areas should relish the pleasant spring-like conditions this week, as a significant shift in weather patterns is anticipated for the weekend, bringing more dynamic and potentially severe conditions.
This upcoming change is driven by a large, powerful low-pressure system that will traverse the country this week. While the core of this system will remain to our northwest, it is expected to extend a frontal boundary into the Southeast by the weekend.
An additional area of low pressure is forecasted to develop along this boundary. This secondary system is expected to enhance the chances of experiencing strong storms, gusty winds, and heavy rainfall from Saturday into Sunday.
The exact influences on our region will depend on slight adjustments in the timing, intensity, and trajectory of the low-pressure systems, so forecasts may be refined as we approach the weekend.
Currently, forecasts indicate that showers and a few storms could commence as early as Friday night, continuing into Saturday morning. The likelihood of strong to severe storms, however, appears greatest during Saturday afternoon and evening, although this is subject to change.
A tightening pressure gradient is expected to cause breezy conditions starting on Friday, persisting through Saturday and extending into Sunday, with a potential “mountain wave wind event” anticipated in elevated areas.
Rainfall could accumulate to 2-3 inches throughout the weekend, and the Weather Prediction Center has acknowledged the potential for flash flooding during this period. While the precipitation is much needed, the rapid onset of such a large volume may pose challenges.
The Storm Prediction Center has also highlighted our region for the potential occurrence of severe weather from Saturday into Sunday morning. Although specific details about timing and impacts remain uncertain, all forms of severe weather, including hail, damaging winds, and tornadoes, are possible.
As the situation develops, the specifics will become clearer. It is advisable to stay informed and have various methods to receive timely weather alerts, including alerts that can wake you during the night. Reviewing your emergency plan and identifying a safe location for you and your family will ensure preparedness should a warning be issued for your area.
Looking ahead, adjustments to the current forecast are likely as new data becomes available. Stay vigilant and prioritize safety by being prepared for this active weather scenario.
