Upcoming 'Spring' Storm

The last few days have been fairly depressing across the area due to the dense fog that has stuck around the area nearly 24/7.  The reduced visibilities of less than a 1/4 mile have created some travel problems, including a very large accident on I-35 in the Kansas City area.  Our fog will finally be coming to an end today, as a storm system will finally increase our wind speeds and begin mixing down some dryer air.  Although our fog will come to an end sometime near the Noon hour today, we'll still be stuck under cloudy skies and likely see some form of drizzle and light rain through the afternoon.  Additional showers and even a thunderstorm or two will be possible this evening and overnight for northern/central Kansas and much of Missouri.  Further north where surface temperatures are going to struggle near freezing we have Winter Storm Watches that have been issued due to the likelihood of freezing rain/drizzle.  Ice accumulations greater than a tenth of an inch are possible throughout much of Iowa and eastern Nebraska, with greater than a quarter-inch of ice possible across central portions of east-central Nebraska and central Iowa.  These watches will likely be upgraded to advisories or warnings for freezing rain later this morning.  Total rainfall amounts of 0.10-0.40" are likely across the region from the KC Metro through much of northern Missouri, eastern Kansas, eastern Nebraska, and much of Iowa.

Additional showers are possible for early Wednesday as a warm front finally lifts northward through KS/MO, bringing an increase in temperatures as well as beginning to clear our skies out.  A low pressure system will move out of the Arklatex region to the northeast, perhaps leaving portions of southern Missouri under additional showers and even a thunderstorm.  Our next storm system will move off of the Rockies late Friday and onto the northern Plains, dragging a cold front with it that will likely push through on Saturday bringing additional rain showers to eastern Kansas and much of Missouri for Saturday and Saturday night.  Areas of Nebraska and Iowa may see rain showers and freezing rain once again as surface temperatures still struggle with the snow pack that remains in areas.  More details on this weekend's system in later updates...

We are trying to get into more of a spring-type systems with a mixture of precipitation types, but we look to fall back into freezing weather after our weekend system for at least a few days.
