The National Weather Service has issued its outlook forecasting isolated to scattered showers and thunderstorms Sunday followed by dry and very warm weather the early part of the week with a push of monsoon moisture beginning midweek.

Areas subject to the outlook include among others Utah’s Dixie, Zion National Park, south-central Utah, Glen Canyon Recreation Area and Lake Powell, central  and southern mountains of Utah and southwest Wyoming.

Critical fire weather conditions are possible, according to the forecast, especially across the western valleys mid- to late-week due to the combination of increasing winds, dry microbursts and low humidity.

At 5 p.m. Sunday, the service reports conditions from airports at Colorado City, Arizona, as mostly cloudy; Bryce Canyon, with light rain; Las Vegas, Nevada, with a few clouds. Other areas in Southern Utah currently report fair conditions.

Lightning: “When thunder roars, go indoors!”

What shelter you choose can make all the difference when lightning is active.  The National Weather Service describes both safe and unsafe shelters:

• A safe shelter from lightning is either a substantial building or an enclosed metal vehicle.

• A safe building is one that is fully enclosed with a roof, walls and floor, and has plumbing or wiring. Examples include a home, school, church, hotel, office building or shopping center. Once inside, stay away from showers, sinks, bathtubs, and electronic equipment such as stoves, radios, corded telephones and computers.

• Unsafe buildings include carports, open garages, covered patios, picnic shelters, beach pavilions, golf shelters, tents of any kinds, baseball dugouts, sheds and greenhouses.

• A safe vehicle is any fully enclosed metal-topped vehicle such as a hard-topped car, minivan, bus, truck, etc. While inside a safe vehicle, do not use electronic devices such as radio communications during a thunderstorm. If you drive into a thunderstorm, slow down and use extra caution. If possible, pull off the road into a safe area. Do not leave the vehicle during a thunderstorm.

• Unsafe vehicles include golf carts, convertibles, motorcycles, or any open cab vehicle.

      I agree, Bob. Maybe in the mountains, then? A seven day forecast and five dollars will get you a cup of coffee at Starbucks, anyway.
