Weather

The Western Slope is ending the month of August on a hot and dry note.

September however, will begin on a cool and rainy note! Showers and thunderstorms from the well advertised low pressure/cut-off low/subtropical tap weather pattern will continue in Utah Tuesday evening and overnight while inching closer to Colorado by sunrise Wednesday. All areas are expected to begin Wednesday with rain and this storm pattern should continue on and off throughout the day. There appears to be an afternoon lull, but very little sunshine/heating is expected and showers will continue throughout the night. The high temperature for Grand Junction (official) is not expected to make it out of the 70s. In fact, the low and the high for Wednesday is only separated by about ten degrees! The rainfall record for Grand Junction on Wednesday is from the 1930s and is .50″.

Flash Flood Watches have been issued for all of the Western Slope locations except the lower elevations/populated areas. Particular attention needs to be paid to the Grizzly Creek Burn Scar along I-70 in Glenwood Canyon by the midday Wednesday for debris flows. Heavy rain will likely continue Thursday with a bit more clearing by Thursday afternoon. The flood watch goes until midnight September 2, 2021, but by that expiration… the storms will have passed the region. Calmer and clearer weather is on tap for Friday and the weekend. The High Country will still pop afternoon thunderstorms and some lower elevations in close proximity will temporarily get blasted with wind. Slow recovery in temperatures is anticipated through the beginning of next week. Afternoon high temperatures for the first week of September look to be a handful of degrees warmer than the averages.
