..Frost and freeze headlines

With many spots putting out plants for Mother's Day, we are starting to issue frost and freeze headlines starting this weekend. NBM probabilities for temperatures less than 36 degrees are 50 percent and higher along and north of Highway 200, although there are some warmer temps progged for the northern Red River Valley. With the shortwave moving through this evening and bringing some showers and cloud cover, conditions will not be ideal for frost formation but enough of a chance of getting below 36 to put out an advisory for tonight. More widespread cold temperatures expected tomorrow night, with high probabilities of under 36 all the way down to the South Dakota border. Chances for under 32 degrees are over 80 percent in portions of northeastern ND and northwestern MN, with some 30 to 40 percent even of under 28 degrees.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 623 PM CDT Fri May 8 2026

Northwest winds will continue for the TAF period, although a more NNW wind is expected to develop this evening and overnight as a front moves through the region. Accompanying this front will be showers with the potential for variations and wind directions and brief wind gusts to 40 knots. Conditions remain quite dry so ceilings will remain VFR regardless with a very low chance for MVFR visibilities from rain.

Winds will diminish after sunset but will rise once more tomorrow afternoon beneath VFR skies. No other aviation impacts are expected to develop.
