745 FXUS63 KDLH 100523 AFDDLH Area Forecast Discussion National Weather Service Duluth MN 1223 AM CDT Mon Jun 10 2024 .KEY MESSAGES... - The entrance of a high pressure combined with clear skies will cause temperatures to drop quickly overnight. Frost Advisories are in effect for portions of the Northland. - Rain showers and storms return for Tuesday and Wednesday. - Active pattern persists through the week. && .DISCUSSION... Issued at 147 PM CDT Sun Jun 9 2024 A weak cold front is leading to cloudy, windy conditions across the Northland today. Directly following, a surface high pressure will settle into the Upper Midwest. Skies will clear this evening, and efficient radiational cooling will cause temperatures to drop into the mid 30s to lower 40s tonight. A Frost Advisory is in effect for north central Wisconsin, the Iron Range, and inland portions of the Arrowhead. High pressure remains over the area through Monday, but with a cool air mass associated with the high, temperatures will remain in the low 70s despite the plentiful sunshine. In addition RHs will be low Monday but with light winds, so near critical fire weather conditions are not likely. This short break from precipitation won`t last long as a pair of shortwave troughs move through late Monday through Wednesday. The first round of showers and storms will be sub-severe, with little instability and a strong low level inversion. With the second wave, there is a small chance for strong to severe storms. While the best environments are further south, MUCAPE values 1000-1500 J/kg and wind shear values 35-50 kts will still be sufficient for isolated severe storms Wednesday afternoon and evening. Models start to diverge by late week, but still show a few more rounds of precipitation in the late week and into the weekend. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1223 AM CDT Mon Jun 10 2024 High pressure will bring VFR conditions through the period. Some fog has begun to develop, but is expected to remain away from the terminals. && .MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 147 PM CDT Sun Jun 9 2024 Northerly winds today will become calm these evening and Monday as a high pressure moves over the area. By Tuesday, winds will have increased out of the south ahead of a low pressure system. Gusts up to 20 kts are possible and could create hazardous conditions to small craft. These winds will be monitored as Tuesday gets closer. For the open water discussion, refer to the NWS Marquette Area Forecast Discussion at weather.gov/mqt. && .DLH WATCHES/WARNINGS/ADVISORIES...
