Few rumbles to the north

Our weather pattern remains fairly quiet, but active for some across the US.  The jetstream remains in more of a zonal flow with storm systems tracking across much of the northern tiers of the US.  Strong winds in the jetstream will push a low pressure system through the northern Plains and into the northern Great Lakes by this afternoon.  As it does, a warm front will continue to lift off to the north through the afternoon with a trailing cold front sweeping through later this evening and overnight.  A few showers/rumble of thunder may be possible through the night before the front passes Wednesday morning.  Stronger storms will be likely into north-central Wisconsin and back through Iowa closer to the main area of low pressure.  Daytime heating and moderate instability will allow some of the storms to produce gusty winds and hail through the afternoon hours.
