Iowa High Temperatures For Sunday 11/2/2014

After ending last week on a cold note, the beginning of this week will be back to average. Temperatures today made it up into the upper 50’s to lower 60’s across the western half of the state. For the eastern half of the state, you only made it into the mid to lower 50’s. Don’t worry, if you live in eastern Iowa, your temperatures will warm up in the upper 50’s tomorrow.

NAM Forecast Precipitation Totals For Monday 11/3/2014

Our next weather system will arrive by Monday afternoon. This system will give parts of the state, a shot at some rain. Right now the best chance will be across central Iowa. This is where rainfall totals will be around a quarter to a half inch. Light rain will work into western Iowa by Monday morning, but it won’t be until afternoon when the moisture will begin to intensify across central Iowa. A cold front will be working across the state Monday afternoon into evening. As this front moves through the state, it will quickly sweep the rain out of the state.

We will get a break in the precipitation on Tuesday with temperatures slightly cooler, but still near average. What is average? Average for this time of year should be in the mid to lower 50’s.

Our next system will then enter the state on Wednesday as a trough will begin to dig into the state. The clouds will be on the increase by Wednesday morning, and so will the precipitation chances. The best chance of precip. Wednesday into Wednesday night will be across northeast Iowa. Rain will begin to enter into northeast Iowa after then noon hour Wednesday. Light rain will then be possible throughout the day Wednesday into Wednesday night. Now one thing of interest, is temperatures Wednesday night will fall into the mid to lower 30’s. This may allow for some flakes of snow to mix in. Not expecting much in the way of frozen precipitation, but it is to note that it may get cold enough before the precipitation moves out that a few flakes of snow may mix in.

GFS Accumulating Snow Through Saturday Morning

We will then get another break on Thursday before another system moves through the state Friday night into Saturday. Once again, temperatures look to be cool enough for snow Friday night into Saturday morning. The GFS model is even showing accumulating snow across northeast Iowa Friday night into Saturday as shown in the image above. Now take the snowfall forecast with a grain of salt right now as we are still several days away, so a lot will change between now and then. The models are also showing a push of cold air to enter the state behind this system with temperatures only in the 40’s by Saturday, as shown in the image below.
