- WINDS WILL BE GUSTY OUTSIDE OF STORMS – POSSIBLY UP TO 45 MPH!!
A potent storm system and associated cold front will bring the risk of strong to marginally severe thunderstorms during the day on Saturday. This will be your classic Low-Instability type event with CAPE Values barely reaching above 400 J/KG. Latest NAM & HRRR Guidance suggests that CAPE will remain relatively low, and there may be a CAP in place. However, since the NWS & SPC remains with a marginal risk, the situation definitely bares watching.
What you can do to prepare:
- Make sure to have a way to receive any watches & warnings that are issued
- Have fresh batteries in your NOAA Weather Radio
- Mobile Battery Packs are recommended in case of power failure to charge cell phones & tablets, etc.
