frost warning

I forgot to post it this weekend, but Minneapolis received a small bit of snow on Saturday morning. Here's the photographic proof. It was just a few flakes, really. They stayed for a few hours in the shade until it finally warmed up. I mention it because we have a frost advisory for the morning. I'll bring in my 2 flats one more time tonight. I hope this time will finally be the last time for that cold danger.

The Minnesota state DNR provides this table for freeze probabilities in Minneapolis in the spring season.

temp (C/F)	probability of target temperature after that date
	0.10	0.20	0.30	0.40	0.50	0.60	0.70	0.80	0.90
2C/36F	May 24	May 18	May 14	May 10	May 07	May 04	May 01	Apr 28	Apr 24
0C/32F	May 12	May 06	May 03	Apr 30	Apr 27	Apr 24	Apr 22	Apr 18	Apr 13

It's only April 23rd today, so there's still historically about a 2/3 chance for another freeze before the season is done. This year, however, has been unusually warm. I'm willing to hope that tomorrow morning's freeze is the last one.
