and Sunday High pressure will drift off to the east today, allowing warming temperatures as surface winds turn southerly today then south- southwesterly on Sunday. Skies will be mostly clear for much of the period, however clouds are expected to increase late Sunday as a low pressure system develops across the upper Mississippi Valley. Overnight lows will only drop off into the lower to middle 30s overnight as surface winds stay up a bit. Although a steep inversion will still be in place on Sunday a much warmer start to the day along with gusty south-southwesterly winds and increased boundary layer temperatures will allow highs to rise into the 50s, with a few 60 degree readings possible across portions of central Wisconsin.
344 AM CST Sat Mar 7 2020 An impressive ridge of high pressure will amplify over the Plains today, bringing well above normal temperatures. Other than temperatures, a southerly pressure gradient will continue the breezy southerly warm advection that has kept overnight temperatures above freezing for most. On Sunday, the ridge will begin to move eastward, but the warm air mass remains in place through the afternoon, bringing another day with highs in the upper 50 to low 70s.

By Sunday morning, think the best bet for the areas of fog would be from east central ND toward Bemidji, with the lowest chances from Elbow Lake to Wadena (where winds should stay higher). Had been keeping a strip of freezing drizzle or ice pellets along the Canadian border overnight, but removed that due to low confidence. Additionally, the signal for anything of more significance appears to be low owing to non-phasing of upper trough while keeping distinct northern and southern streams.

Min RH values with the lower dewpoints still remain at or above 30 percent with the majority of areas 35 to 40 percent based on the lower dewpoint forecast.
With low level moisture increasing and winds expected to remain in the 10-15 mph range overnight, temps should not drop much below the lower 40s. A cold front will approach from the northwest Sunday afternoon and evening with a thermal ridge extending northward along its leading edge. Farther north, thermal profiles are cooler and snow is deeper, so there will be a pretty impressive and interesting temp gradient and temps will remain in the mid 40s to lower 50s there. The front will pass through and bring cooler air back in Sunday night.
As we head into this evening and into Sunday morning the ridge will move east of the area as an upper level trough digs across the plains. The good part of the winds is that they with remain southerly which will continue to bring moisture into the area and warmer air as we head into Sunday.
The latest surface map features high pressure centered across the Ohio Valley, with ridging extending northeast into the eastern Great Lakes region, and southwest through the lower Mississippi Valley.
