Could It Be?

Today was a beautiful day across the state. Highs ranged from the mid 30’s to the mid 50’s across the state. Wednesday is going to be even warmer with highs ranging from the lower 40’s to the lower 60’s across the state. The warmest spot on Wednesday will be across the southwest corner of the state. Winds will be gusty on Wednesday, however, that strong southerly breezy will allow those temperatures to really warm up. Winds will be gust up to 25mph at times throughout the day.

The weather will begin by the end of the week. Wednesday night, a brief disturbance will move through the state. This will bring a chance for light rain and snow across the northern portion of the state. Not expecting much in the way of accumulations. On Thursday, highs will be cooler as they will range from the lower 30’s to the upper 30’s.

The bigger weather system will arrive on Saturday. Right now, there are still a few discrepancies between the models. The ECMWF and the GEM are on the same page, where the GFS is throwing the most question marks into the mix. Pictured above is the 12z ECMWF take on the snowfall. The ECMWF has been consistent the past couple runs, as it brings a moderate to heavy snow band across central and southeast Iowa.

cmc_snow_acc_east_23Comparing the ECMWF to the GEM (Canadian model), it too is showing a very similar path to the ECMWF.

gfs_6hr_snow_acc_east_24Last but not least, is the 18z GFS take. As you can see, it is depicting that warmer surface temperatures will have an impact on snowfall totals. Because of the uncertainty, it is way too early to talk numbers, only trends at this point. We will continue to watch all of the very latest developments and will bring those to you throughout the remainder of the week.
