Dry weather with near record highs is likely once again today. Most communities should see highs in the 60s with temps around 70 across the Snake River Plain and Magic Valley. Winds will be increasing as well today. Some locations will probably reach wind advisory levels from Arco through INL to Rexburg and north. Have decided to hold off on a wind advisory as today is somewhat marginal. But the bigger reason is Monday is the bigger wind day with stronger winds affecting a larger area. On Monday, a cold front will arrive from the northwest during the afternoon. Winds will likely reach wind advisory levels from Shoshone to Blackfoot and north. Some patchy blowing dust is likely as well which very well could be strong enough to close the interstate around the Roberts area. Probably a 30-50% chance that visibilities would drop that low from the dust. The front will not have much moisture with it, probably just looking at a few scattered showers with less than 0.10 inches of qpf. Temperatures look cooler Monday with highs in the upper 50s for the mountains and highlands to mid 60s for the Snake River Plain and Magic Valley. These temperatures should fall short of the records.

Forecast gets complex from Tuesday onwards. Seeing indications that the front will either slow or stall across southern Idaho or northern Utah. The past couple days, Tuesday looked dry, now not so much. Potentially if the front stalls close enough to southern Idaho we could see showers work along the front and affect southern Idaho. The forecast for Wednesday through Friday still looks cool and wetter. During this time, mean qpf ranges from around 0.40 inches across the lower elevations to around an inch for the upper slopes and ridges. Temperatures for Tuesday and Wednesday look seasonable but then fall below normal for Thursday and Friday. So we probably will see some accumulating snow as low as 6000 feet but the heavier accumulations will likely be above 7000 feet.
