Update On Late Weekend-Early Week Storm SystemMarch 21st, 2013 at 9:59 am by Chad Evans under Chad's WLFI Weather Blog
One thing I have been able to confidently decide is that the Sunday-Monday (even some scattered precip possible Tuesday) system looks like all snow now. Entire column will be below freezing early Sunday morning as precipitation moves in with excellent dendrite growth & saturation noted in the SGZ (Snow Growth Zone).
What I do not feel confident about is the storm track & corresponding snowfall amounts. Whether the heavy band is directly across the area or just to the north or just to the south is in question.
Time will tell with new data over the next couple of days on whether this will be a significant late-season event or not.
Regardless, I like “snow possible” with removal of any rain or rain to snow wording for the forecast early Sunday morning-Sunday afternoon & evening, (before steadier snow ends Sunday night). This looks to be followed by scattered snow showers Monday to even Tuesday that will be largely driven by daily heating. There will be a lot of cold air aloft, so scattered of brief, occasionally intense, snow showers looks good there.
High of 34 looks good Sunday, low of 31 Sunday night & 34 Monday, 27 Monday night & 36 Tuesday.
