Happy Spring everyone! Wait, it is really anything but spring like
outside right now across Iowa. In fact, there is a bunch of light snow
going on across the western half of the state right now. What gives?
Alas, that tends to be March, and even April at times, in the Midwest.

Morning lows ranged from the mid 20s out east to the low and mid 30s
to the southwest, and had not moved too much by late morning with many
areas in the low to mid 30s currently. The light snowfall slowly moved
into western Iowa early this morning and is just now making its way to
the ground in areas of central Iowa. As the afternoon continues, light
will linger a while longer but is expected to fade before it can reach
eastern Iowa. Total snowfall accumulations of around an inch may be
seen in northwest Iowa, while areas further south and east will
quickly fade to under a half inch and trace amounts.  

Temperatures the rest of the week will warm a bit, but tend to stay
away from widespread spring like temperatures. Highs will peak 
Thursday and Friday ranging from the mid and upper 40s to the north 
and northeast to the 50s and even around 60 to the southwest. A quick
moving system may bring a brief hit of rain and snow Thursday morning,
but is not expected to accumulate with temperatures quickly warming.
The bigger impact may come Friday into Saturday as a system brings
about widespread rain and snow chances. Northern Iowa will have the
best shot at accumulating snow while central and southern Iowa will
likely see predominantly rain.
