DISCUSSION

Currently the low stratus and patchy fog continue to hang on across the state. In higher elevations there are still visibilities between half and one mile. The trends the last few hours are the stratus breaking up, especially in the central. Tonight with the moist southerly winds, more patchy fog is possible in the Highway 83 corridor, especially near rivers and bodies of water.

Aloft a ridge is over the Dakotas, with an open wave dry clipper developing over the Canadian Rockies. Through the end of this week temperatures will be near or above normal with the warmer air in the ridge. Late Friday night that clipper system will pass by with a trailing front in a surface trough. This will cause winds across the state to be very breezy with west winds at 20 to 40 mph from the front and pressure gradient. Sunday winds switch to the south as a high pressure in Colorado crates a surface ridge over the Dakotas. With these strong southerly winds, expect highs in the 60s. Temperatures will then stay above normal (45 degrees) in the 50s through most of next week with warmer flow from the Pacific Northwest. After Tuesday another possible clipper system could bring some light rain or snow in the far northeast and cooling highs to the 40s up there. Elsewhere temperatures could remain 10 degrees above normal.
