The forecast this week, as it will be for much of the summer, is driven by a warm ridge of high pressure, which is currently located of the Western United States. Nederland and the Colorado Front Range are currently on the east side of this ridge which places the area under a northwesterly upper wind flow. Moisture and pieces of weak upper level energy will result in the possibility of afternoon and evening thunderstorms on Monday and again on Tuesday. The ridge will push slightly eastward by Tuesday resulting in warmer temperatures. Tuesday will be the warmest day of the week with temps nearing 80 in Ned. By Wednesday, Pacific energy will begin to erode the ridge and force it to retrograde (move westward). This will allow cooler air and more moisture to push into Northeastern Colorado. This will increase chances of afternoon and evening thunderstorms Wednesday and Thursday. Friday and Saturday look to be decent days with near normal temperatures and only isolate afternoon showers. Monsoonal moisture may begin to infiltrate the region by Sunday.
