Area Forecast Discussion National Weather Service Duluth MN 523 PM CST Sun Mar 7 2021

DISCUSSION. (This evening through Saturday) Issued at 432 PM CST Sun Mar 7 2021

Summary: A few sprinkles or flurries possible in the Minnesota Arrowhead tonight. Above average temperatures will continue in the beginning of the work week. High temperature records could be broken on Tuesday. A change in the weather pattern presents itself in the middle of the week. Dry conditions return with temperatures closer to normal to end out the week.

A weak shortwave moving through Minnesota brings the possibility for some light sprinkles or flurries this evening into tonight. Monday morning, an upper level ridge over the Northern Plains will keep us dry and warm, with above normal temperatures into the work week. High temperatures in the 50s Monday are expected as northwesterly flow aloft turns southwesterly. A warm air mass aloft will move northeast through the Northland on Tuesday, with NAEFS Ensemble 850 mb temperatures well into the 90th percentile of climatology. Thus, high temperatures will be nearing the 60s and close to tying record highs across the CWA on Tuesday, with the potential of a few to be broken.

Global models show a couple systems moving through the upper Midwest as a trough makes its way east and the ridge moves out of the area. A surface low caused by divergence in the left exit region of a jet stream on the back end of a ridge will move north of the Dakotas and Minnesota. Most of the precipitation should stay to the north of us in Canada. However, areas along the International Border could see some light rain or sprinkles at the edge of this system. As this low exits, another forms in the Northern Rockies and moves through the Midwest into our area Wednesday morning. Uncertainty remains what the initial precipitation type will be in northeastern Minnesota due to variations in the guidance, but there is fair agreement that northwestern Wisconsin should start with rain. As the day progresses, precipitation should shift to rain or a wintry mix, then slowly shift back to snow as cold air is advected behind the system. Some freezing rain mixed in as the transition to snow occurs is possible in scattered areas across northwestern Wisconsin and northeastern Minnesota. The system should move out Thursday morning, with the end of the week settling back into a dry pattern, with temperatures closer to normal in the mid 30s.

AVIATION. (For the 00Z TAFS through 00Z Monday evening) Issued at 511 PM CST Sun Mar 7 2021

VFR conditions are expected to continue for the rest of the day. Low level wind shear due to a tight gradient aloft is present across northwest WI, affecting the HYR terminal. Some low MVFR clouds are possible this evening at INL and HIB. Guidance also includes the possibility for some fog at BRD, but the atmosphere should be dry tonight, which will inhibit fog from forming. Thus, fog was included but kept VFR. All terminals should remain or rise to VFR as we head into tomorrow morning.
