Everything looks to be on track with our quick moving and fairly weak weather disturbance that is currently pushing into portions of the Midwest this evening and will lead to a quick hitting round of accumulating snow across portions of Illinois later tonight and into tomorrow morning. As mentioned earlier, this will not be a big deal event but given we are now into the middle part of March, it is somewhat noteworthy and worth mentioning.
The latest on this system follows below...
Our wave is currently moving across portions of Iowa this evening and will continue southeast into and through Illinois later tonight and through the overnight hours.
As we get a look at current radar across the Midwest, we can see that precipitation continues to slowly develop to our west across Iowa and this will eventually move into portions of western and northwest Illinois later this evening.
Snow will continue east and ESE overnight tonight in a fairly narrow corridor which continues to be well modeled on high resolution model guidance. Even though snow will fall over a small area, it could snow rather heavy or intense in the band given the favorable ingredients in place for a few hour period of heavy snow. This could lead to a quick 1-3" of snow in spots wherever this band establishes itself.
Snow will quickly end from west to east early tomorrow morning with the rest of the day quiet and drying out with high pressure moving in from the west. Our thoughts on snow totals has not changed much and we will update the map below if need be later tonight.
