A heat advisory has been issued for northern Utah, specifically targeting areas along the I-1 5 corridor and the West Desert, as temperatures are forecast to reach the upper 90s to low 100s on Monday afternoon. Additionally, a Flash Flood Watch remains in effect for southern and portions of central Utah until midnight MDT tonight.
Monsoonal moisture continues to move northward, bringing the potential for scattered showers and thunderstorms across parts of central, southern, and northeast Utah, as well as southwest Wyoming. The risk for flash flooding remains a concern for much of the forecast area, with the WPC highlighting a Marginal Risk of exceeding flash flood guidance daily through at least Thursday.
A Slight Risk of exceeding flash flood guidance exists for southern and central Utah this afternoon, with additional risks noted for southwest Utah on Tuesday afternoon and northern Utah and southwest Wyoming on Wednesday.
In southern and central Utah, thunderstorm development may be delayed until closer to 3 p.m. today. High moisture levels could support efficient rainmakers, leading to heavy rainfall from well-established storms.
Looking ahead to the weekend, a mid-level trough is expected to bring drier westerly flow, which will likely limit precipitation chances primarily to higher terrain. While uncertainty remains for Wednesday regarding potential damaging winds in northern Utah and southwest Wyoming, current guidance suggests increasing moisture levels could lead to heavier rainfall and thunderstorms starting Tuesday afternoon.
