Same here, WH. We got up to 64F yesterday and I was still slightly chilled in a long-sleeved shirt. The forecast here was for freezing night temps this coming Monday and Tuesday. Looks like they've changed that to a slight (31F) freeze tonight and that's the only freeze in the foreseeable future forecast...rain moving in Friday night for a few days then clearing and...turning back colder.
As for the muck. We had some clearing around the yard done (@*"&^#!!! privet hedge!!!) and some "topsoil" hauled in for low spots. That topsoil is some sticky, gooey, slick snot. I'm hoping that the freeze and slight heaving/"spewing" of the surface layer is what affected it and that's not typical of how it's going to be...will be glad when (hopefully) we get some grass growing in it. When we had the work done it was really too late to get grass established so that is yet to be seen.
Last Wednesday the high was 30.5F. Sunday the high was 73.1F. It looks like we're going to be stabilizing for a week in the upper-50F to mid/low-60F range...with rain thrown in for fun.
ETA: BUT...I'd rather have my weather than your thawed out frozen ground!!!!!! I can see how that *would* make a mess!!!!!
