Here we are, back in that always interesting time of the year when both winter and severe weather can strike. Long range models show a little bit of both are possible in the coming days and weeks, before a more seasonal transition to much cooler weather by the latter half of November. With that being said, it’s time to focus on a storm system set to affect Iowa for the first half of the coming week.
By late Monday Night into Tuesday, the storm will begin to affect the area. Moving up from the south, the quickly developing storm center will bring very heavy rainfall to the region. In fact some areas could see 2 or more inches of rain when all is said and done with. This will produce a very dreary period over much of the state.
As things begin to wind down and the storm moves off to our north and east, wraparound moisture will push in. Coupled with dropping temperatures, some areas could see some light flurries or snow. It could be a little more serious in portions of western Iowa. Some of the models are forecasting a period of dendritic snow. If this feature were to verify, it could lead to light to moderate snowfall accumulations in far western Iowa.
The National Weather Service in Des Moines has already advised that if that were to happen, it would justify the issuance of a Winter Weather Advisory either Tuesday Night or Wednesday Morning. Something to keep in mind if you are traveling in this area. We’ll continue to monitor the possibility of any advisories. I will say it looks like we could see something issued. Forecasters like to err on the side of caution with the first measurable snowfall of the year here in Iowa.
