Wind and Rain on Veteran's Day

An intense low pressure storm system is spinning over Minnesota tonight.  A cold front drops southwest from the low across northwestern Iowa, eastern Nebraska across western Kansas.  There is a tight pressure gradient associated with the low so that southerly winds will blow tonight, and for a good part of the day on Sunday from 20 to 30 mph with gusts on Veteran's Day expected to reach around 40 mph.  With this strong southerly flow over night, temperatures will not drop much.  The lows will be in the middle to upper 50's across the Stateline.  The average low this time of year is 33 degrees.  There could be a couple of light rain showers overnight, but nothing much is expected.  The front will be moving eastward across Iowa on Sunday, and as it gets closer to the Stateline showers will develop.  Showers will be likely by noon time, and you can expect occasional rain during the afternoon.  There might even be some late season thunderstorms.  The temperature will top out in the low to middle 60's.  The average high this time of year is 51 degrees.  The cold front will probably move across the area by the supper hour.  The wind will switch to the west at 10-15 mph, and rain showers will continue through the evening. Much colder air will feed into our region by midnight, and there could be some rain mixed with wet snow before it ends well after midnight.  A steep drop in temperature will continue taking the overnight low to around 28 degrees.  It will be partly cloudy, breezy and cold on Monday with a chance of afternoon snow flurries.  The afternoon high will only be around 33 degrees.  That will be quite a shock after being in the 60's over the weekend.
