A soggy Sunday of rain, fog and possible thunderstorms for eastern Iowa
Spring fever will be in the air through Monday. Temperatures more typical of mid-March along with showers and possible thunderstorms will certainly add to that feeling.
A strong storm system will approach the state from the southwest on Sunday. Eastern Iowa will be on the warm side with areas of light rain/drizzle and fog through much of the day. As the system gets closer rain will become more steady Sunday night and with enough instability a few thunderstorms are certainly possible into Monday morning.
Rainfall amounts will be fairly decent considering it's the middle of January. A couple models have accumulations of a half inch to an inch with locally higher amounts likely in areas that do happen to get under a thunderstorm.
The "winter" side of this storm will not be that far away. Winter Storm Alerts are in affect for portions of northwest Iowa where significant snow accumulations of 6-12" is possible late Sunday night into Monday. Be advised if you or anyone you know is going to be doing any traveling in that part of the state.
Eastern Iowa will likely see a transition to light snow Monday night as cold air wraps around behind the storm as it tracks into the Great Lakes region. However, little to no accumulation is expected.
