KEY MESSAGES

- Temperatures dropping below 36 degrees will bring areas of frost to portions of northwestern and west central Minnesota tonight into Monday morning.

..Frosty temperatures tonight

Surface high pressure extending from Manitoba into the Dakotas will begin to shift eastward tonight. Cloud cover from the reinforcing shortwave currently digging into northeastern MN will also shift eastward, although can't completely rule out some more cirrus coming in from the west towards morning. Best chances of temps bottoming out below 36 degrees are in the Lake of the Wood region and in west central MN. NBM has probabilities of getting below 36 of 60 to 70 percent in some areas, but at this point 32 and below seems unlikely. Most of that area is boggy and unlikely to have impacts, but there are some areas in the western portions of the advisory area that have more population. Further west into the Red River Valley and eastern ND, there will be more wind as winds start to pick up from the southeast as the high pulls away. Not completely ruling out frost formation particularly near the Canadian border, but not confident enough to include quite yet.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

VFR conditions prevail through the period at all TAF sites. Winds increase out of the south to southeast this morning, with gusts into the 20-25 knot range by midday to early afternoon. Broken VFR clouds this morning give way to scattered cloud cover this afternoon and evening. LLWS is possible late this evening in portions of northwest Minnesota, with KBJI seeing the highest probability around and after 05Z.
