SALT LAKE CITY (ABC 4) – Good day, Utah! Wicked winds on deck for our Wednesday in many parts of the state, while a quick moving system could deliver wet weather to Northern Utah. The best chance for wet weather looks to be during the afternoon and overnight hours Wednesday into Thursday.
Light measurable moisture is possible in our valleys while an inch of snow to a few inches looks possible in our northern and central mountains, above 6,000 feet. As this system moves through Utah, it also brings the chance of thunderstorm development to a bulk of the state. The Storm Prediction Center has put out a general thunderstorm risk for the Wasatch Front, western side of Utah and SW Wyoming.
Gusty southerly winds are going to intensify in southern Utah. Parts of the state, especially Washington County, have faced air quality impacts as a result with moderate air. We also have ozone levels rising in parts of the state including Eastern Utah, with sunshine and heat promoting the chemical reaction that creates ozone. As a result, we have moderate air quality projected for the Wasatch Front from Davis County southward and the Uinta Basin, plus Carbon, Washington and Iron Counties.
Winds are also going to contribute to an elevated fire risk. We have dry fire fuels, low relative humidity and gusty winds which could easily spread flames. As a result, we have critical fire danger in the South Central and Southeastern Utah and a Red Flag Warning goes into effect for the Grand Staircase Area, Iron County and Washington County at noon. Any fire start would spread quickly Wednesday.
Temperatures will slightly cool into Thursday, and the day will remain unsettled. We could see an isolated shower Thursday, and by Thursday afternoon we’re back to dry skies as high pressure takes charge. This will lead to dry skies to close out the week and move into the weekend as we warm up in a big way!
Bottom Line? A quick-moving system brings the chance for storms, wicked winds and fire danger.
