KEY MESSAGES
- Areas of fog today and Thursday morning.
- There is a 20% chance for advisory impacts from a wintry mix Thursday into Friday.
- A more active pattern may continue into next week bringing additional opportunities for winter impacts over parts of the region. Predictability in impacts remains very low beyond Friday.
..The Weekend and Beyond
Southwesterly flow brings another wave into the Upper Midwest Friday/early Saturday. The GFS and its ensemble members remain further north and stronger with this system, while the Canadian and European ensemble suites are further south/weaker. The most likely area to see any impacts would be our southern FA Friday afternoon into the overnight, but at this time there remains significant uncertainty in where/if any will occur. Behind this system, a return to zonal flow brings a surge of warmer Pacific air. A few weak waves are shown by various model guidance early in the week, but there is little agreement in each features placement/timing/strength. There is broader agreement in a larger system within our region towards the middle of next work week. However, there remains considerable spread in potential scenarios regarding the systems final evolution.

IFR to LIFR conditions prevail at all TAF sites this evening. BR and FG will impact aviation once more tonight into Thursday morning with 1/4 to 1/2 mile visibility and ceilings less than 500 feet. There could be brief periods with snow flurries at KDVL, KGFK and KTVF, especially prior to 12Z. Conditions will be slow to improve Thursday morning, and will be dependent on how quickly the winds pick up heading into midday. Moisture levels are increasing from south to north, which will continue to support fog persistence into Thursday morning. Winds are expected to shift to the east to southeast around 18Z, then increase into the range of 10 to 20 knots.
