Severe Thunderstorms Expected Early Saturday Morning

SUMMARY: Isolated thunderstorms are expected Friday night into Saturday morning, before a line of strong to severe thunderstorms accompanies a cold front Saturday morning. Additionally, expect windy condition as the front nears the region.

TIMING: Windy conditions throughout the day on Friday, thunderstorms Saturday morning

AREAS: All of Coverage Zone 1, 2, and 3.

POTENTIAL HAZARDS: Winds outside of thunderstorms will be in the 10-20 MPH range beginning Friday. Damaging winds in excess of 60 MPH, and tornadoes.

ACTIONS ADVISED: Prepare now for gusty winds by securing all loose outdoor items, including holiday decorations to prevent loss or damage. Prepare for any Watches and Warnings issued by the National Weather Service. Know your severe weather plan in case Warnings are issued. Prepare for power outages. Ensure electronic devices have a proper charge in the event of a power outage.

DISCUSSION:

HI-RES model data is showing isolated thunderstorm development before a vigorous line of thunderstorms approaches Saturday morning. Sufficient SHEAR/moderate CAPE will be in place for thunderstorms ahead of the front to be severe. Even though this is looking to be a face-paced squall line, NWS does have portions of the area in a Marginal Risk for Excessive Rainfall.
