Winter Storm: Feb. 7/8 Update #2

Several NWS offices have begun to issue their latest forecasted snow totals for portions of the Plains states.  The Topeka NWS office has decreased their amounts compared to their first forecast, with only 5-7" expected in their warning area with less amounts to the north. This 5-7" line has shifted slightly south as well, just south of the Kansas City Metro to align with the forecasted totals from the Kansas City NWS office as well.  The Des Moines NWS office on the other hand did actually increase the snow totals for parts of central and eastern Iowa where 10-13" is now forecasted.  This area is currently the favorite to see a prolonged period of moderate to heavy snow as the upper level low from the northern stream stalls for a moment during the day Monday before moving eastward during the evening and overnight.  It is important to note that any changes in the path of the northern stream upper level low could create a change in the forecasted snow totals.  I've posted the latest NWS maps regarding storm totals below, these are all as of 1:30 PM on Sunday.
