SALT LAKE CITY () – Happy Wednesday, Utah! We're into July, and after a hot start to the month with heat advisories, we will see highs drop about five degrees today.
We will remain a few degrees above seasonal norms with temperatures along the Wasatch Front expected to hit the low to mid-90s, with Washington County closer to the St. George average of 100 degrees. You may also notice more cloud cover today as monsoon moisture continues to stream into the state with a southerly flow in place.
Bottom Line? Increasing clouds and isolated thunderstorms today with an elevated flash flood threat.
A monsoon set up is in place with a large area of high pressure near the Four Corners, and an area of low pressure to our west gradually moving inland. Our monsoon flow is grabbing some of this monsoon moisture to the south and ushering it into Utah meaning we have the chance of isolated thunderstorms today.
As the low gets closer to Utah, we will see an uptick in storm potential especially Wednesday evening and into Thursday afternoon. Nocturnal storms are possible into Thursday morning and these storms will pack gusty winds, lightning and the chance of brief, heavy rain.
With more moisture potential, the flash flood risk will increase today. Flash flooding is possible at all of our National Parks and surrounding recreation areas like Red Cliffs, Canyonlands, Grand Staircase and near Lake Powell. It's important to mention that you should never cross flood waters and seek higher ground if you are caught in the path of a flash flood. Slot canyons and normally dry washes in southern Utah are not safe.
Looking ahead to your Independence Day, drier air will return with only a slight chance of a pop-up thunderstorm in Northern Utah. Daytime highs will be right around seasonal norms, so highs will be near 90 along the Wasatch Front and 100 in Washington County. High pressure will regain control with a chance of an uptick in winds, leading to potential fire danger. The holiday weekend looks sunny, hot and dry as of last check.
Summer conditions can shift quickly, so stay weather aware this weekend. We'll keep you updated in our 4Warn Weather forecast both on-air and online, we are Good4Utah!
