We continue to keep our eyes focused on Thursday as a large storm system will move across the upper midwest. This will bring the chance for rain, freezing rain, and even snow. Yes snow. After having highs ranging from the upper 50s to the mid 40s, we will snap back to reality on Thursday.
A surface low will move out of Kansas and will track to the northeast. As it does, the low will deepen. There is a lot of moisture with this system so this will lead to moderate precip totals. Precipitation will begin after midnight Wednesday. It will be warm enough that precip will begin as rain and then will transition over to freezing rain then snow. This transition will take place from northwest Iowa to southeast Iowa. The greatest chance for heavy snow will be focused on the I-35 corridor and across northeast Iowa. This is where a blizzard watch has been issued.
The blizzard watch goes into effect from Thursday morning through Thursday night. This is because wind gusts will be near 55mph. Combine this with the moderate to heavy snow, and this will lead to white out conditions. Snowfall totals in the blizzard watch will be between 3 and 7 inches. The heaviest of the totals will be across northeast Iowa. Ice accumulation will not be a big issue as we are only expecting minor ice accumulations. Snowfall rates of 1 to 2 inches will also be likely during the peak of this storm.
Across southeast Iowa, most of the precipitation will be all rain, with very little snow accumulation possible. The morning commute will be wet, but will not be slick. Snow will begin around the noon hour so the evening drive home will be slick. As always we will have the very latest details on our facebook page and right here at Iowachase.com.
