A clipper system will slide through the area tonight bringing strong winds and light snow so read on for the details…
An Alberta clipper system will impact the area later tonight into Wednesday morning. Strong northwesterly winds will be felt statewide in the evening to overnight period with the highest gusts of level 4 and 5 on my wind scale. Snow showers will also be possible during this time across the northern part of the state which has lead me to issue a Winter Weather Advisory including the northern two county rows for visibility issues during falling snow and a quick trace-2″ of snow accumulation. That said, the main risk will be strong wind gusts later tonight into Wednesday morning. Due to the snow that fell this past weekend I have issued a Blowing Snow Advisory that does cover the central and eastern part of the state where visibility could greatly be reduced later this evening from strong wind gusts. Cold dry air will set in behind the system later tonight sending temperatures back into the single digits by Wednesday morning. The strong winds will continue through daybreak on Wednesday and finally calm down later Wednesday evening. The snow and wind models are available below.
An additional storm system will pass through the central plains Wednesday night into Thursday. We will have the bulk of the snow south and west of the state. Some numbers show the system passing just south of the state but my models are pointing towards at least the chance for some light snow across southwest Iowa. Overall this should be a nuisance event with the possibility of some light snow accumulation Wednesday night.
