Temperatures are rebounding quickly into the upper 60s and 70s across the Northland today with 70s expected in the near future for highs, even near 80 degree highs next week. The Weather Service is forecasting morning lows to remain mostly in the 50s for the next week or longer so if your plants survived Thursday morning they should be fine for a while.
