Looking at the models this morning, it is beginning to look like we will end up with a brown Christmas. There is one small disturbance that will move through the state on Wednesday, which will allow for light rain during the day Wednesday. As cooler air moves in by Wednesday evening, rain will transition over to light snow across northern Iowa.
The reason for seeing rain instead of snow on Wednesday, is temperatures will be 10-degrees to 20-degrees above average. Just look at how temperatures will shape up in the week ahead:
Sunday: Near 40° to near 50°
Monday: Low 30’s to low 40’sTuesday: Low 40’s to upper 40’s
Wednesday: Upper 30’s to low 50’s
Thursday: Mid 30’s to upper 40’s
This above average temperature trend has been great for some, but for those of you that have been wanting snow, it has been a nightmare! The kicker is that a few of the models are showing a larger storm system after Christmas, around the 27th and 28th. The 12z GEM today was the most aggressive with this system. As shown above, it takes the perfect track to produce all snow across Iowa. With it being over a week away, changes are likely. It is just something to keep in the back of your mind if you will be traveling home after Christmas.
