It has been a soggy day and the rain continues tonight and continue through Wednesday. The rain finally will taper off Wednesday evening. Mild temperatures, in the low 50s tonight, linger into Wednesday morning. Temperatures slowly fall into the upper 40s during the afternoon. Here is the rain potential from Tuesday evening to Wednesday evening.
A gusty south wind continues through Wednesday evening. Wednesday night the wind starts to come from the west pushing dry air across Iowa clearing the clouds around midnight.
The sky remains clear through Thursday night. Wind gusts could reach 45 mph Thursday from the west and then gradually diminish Thursday night.
Here is the forecast map for Thursday morning.
We are tracking the chance of a rain/snow mix changing to light snow Friday afternoon into Friday night. The moisture initially has to overcome the dry air in place Friday morning. The map below shows the dry air over Iowa Friday morning.
The ground is wet and warm (50s)…that has to cool down before snow begins to accumulate. The map below shows the road temperatures.
The exact track of the precipitation and duration is still a bit uncertain. Timing, at this point, is a rain/snow mix sometime in the afternoon Friday changing to light snow Friday evening. The light snow tapers off by sunrise Saturday morning. So this could impact your Friday evening commute and possible Saturday morning. Stay up to date on the forecast through the rest of the week.
Now if all of this plays out in the favor of snow, minor snow accumulation is possible. Minor snow, here in Iowa, is 3” or less. The map below shows the chance of 1″+ of snow through 6 pm Friday.
Exact forecast snow amounts are still unknown at this time since there is plenty of uncertainty. We will continue to track our potential first snow of the season.
