IWN Winter Weather Advisory
IowaWeatherNow.net has issued a WINTER WEATHER ADVISORY for areas shaded above.
Date: 3/8/19 at 12:20pm CST
Timing: Effective Saturday….
Discussion: A jet streak will reach the Rocky Mountains tonight and will cause a surface low to develop in southwest Colorado. This surface low will track more north allowing for the rain/snow line to be further north as I did mention yesterday, this also will make for a direct southerly flow pulling warm air north as heavy rain begins Saturday morning. Rainfall amounts should range 0.5-1.0″ with locally higher amounts but the rainfall rates will be high so with that being said I do think that some ponding and possibly even flooding could be noted in some areas. Then by Saturday afternoon cold air will work into the system allowing for backside snow in the afternoon to evening where most areas will see a quick 1-3″, locally 3-6″ in the extreme northern counties possible. Strong southeast winds will gust 40-55 MPH during the day Saturday, peaking Saturday night before switching to the northwest on Sunday. In addition to the rain and snow, blowing snow will be possible, especially in the northern counties Saturday night into Sunday.
– Light snow
– Blowing Snow
