Weather Hurdles

18zWe continue to keep our eyes on a few hurdles that we will have to jump over before we get to a warmer weekend. The first hurdle is very small. It will be a quick clipper system that will move through tomorrow morning bringing a quick shot of very light snow to southern Iowa. The best chance for this snow looks to be along the highway 34 corridor. This is where up to one inch of snow could accumulate with most areas in southern Iowa only seeing less than a half of an inch. Temperatures will then warm up on Thursday and will continue to climb up from there.

Temperatures aloft will be above freezing and surface temperatures across southern Iowa will also be above freezing slightly. Temps across the north will be cooler so this is where the troubles come in. It does appear that we will see freezing rain to start off with then briefly transition over to all rain, then back to a freezing rain/wintery mix. The issue at this current time is where will this freezing line set up and how long will precip fall as freezing rain. The 18z NAM also tries to wrap some moisture around on the back side which would bring snow to central Iowa, but right now I am viewing this as an outlier.

We will have to continue to monitor this as there will be plenty of moisture to work with in this system and that could amount to some ice accumulations, but the million dollar question is how much? We will have our eyes on this very closely and will continue to bring you the very latest at Iowachase.com.
