Minus the wind today it was a very nice fall day. We had lots of sunshine (see image below) and afternoon temperatures reaching into the low 50s in many locations.
A cold front will move south across Iowa tomorrow as clouds build along it. Right now I am not anticipating any showers along the front during the day. The front will stall along the Iowa/Missouri state line Friday night. As low pressure west of Iowa strengthens, the cold front will transition to a warm front and begin to lift north Friday night and Saturday morning. Along the warm front there will be a slight chance of a shower/storm Friday night and Saturday morning. The map below shows the forecast position of the warm front Saturday morning.
The wind will be strong (35 mph gusts) from the south on Saturday pushing the warm air north as our high temperatures are forecast to reach the mid-upper 60s.
Here are the record highs for Saturday, November 10:
Waterloo: 69 in 2010
Dubuque: 69 in 1949
Cedar Rapids: 70 in 1949
Iowa City: 70 in 1915
The low will track northeast into southern Minnesota by Saturday evening. The cold front that will be extended southwest of the low will swing through Iowa Saturday night and Sunday. Along the front rain is likely here in eastern Iowa.
Here is the forecast position of the cold front Sunday morning.
Here are the ECMWF and GFS models for noon Sunday showing the rain along the cold front.
As mentioned above, rain is likely on Sunday and some areas may see rain totals exceed one inch. After the cold front crosses eastern Iowa Sunday, the morning highs in the low 50s will fall into the 40s. The wind will shift to the northwest with gusts to 30 mph. Here is the rain forecast from Saturday evening to Sunday evening.
The rain will taper off Sunday evening as temperatures continue to fall. Monday will be a much colder day with highs only in the mid 30s. The wind will diminish Monday night and the sky will clear. There is a pretty good chance that the low temperatures Tuesday morning could be in the teens.
High pressure will keep the weather dry next week but cooler than normal.
